Instructions for Classification of Underlying and Multiple Causes of Death – Section IV – 2022

SECTION IV - CLASSIFICATION OF CERTAIN ICD CATEGORIES

A. Infrequent and Rare Causes of Death in the United States

The ICD contains conditions which are infrequent causes of death in the United States. If one of these conditions (see Appendix A) is reported as a cause of death, the diagnosis should have been confirmed by the certifier or the State Health Officer when it was first reported. A notation of confirmation should be recorded on the copy of the certificate sent to NCHS. In the absence of this notation, the NCHS coder will code the disease as stated; the State Health Officer will be contacted at the time of reconciliation of rejected data record by control cycle to confirm the accuracy of the certification.

B. Coding Specific Categories

The following are the international linkages and notes with expansions and additions concerning the selection and modification of conditions classifiable to certain categories. They are listed in tabular order. Notes dealing with linkages appear at the category from which the combination is EXCLUDED. Therefore, reference should be made to the category or code within parentheses before making the final code assignment. For a more complete listing, refer to NCHS Instruction Manual, Part 2c, ICD-10 ACME Decision Tables for Classifying the Underlying Causes of Death, 2022.

The following notes often indicate that if the provisionally selected code, as indicated in the left-hand column, is present with one of the conditions listed below it, the code to be used is the one shown in bold type. There are two types of combination:

with mention of” means that the other condition may appear anywhere on the certificate;

when reported as the originating antecedent cause of” means that the other condition must appear in a correct causal relationship or be otherwise indicated as being “due to” the originating antecedent cause.

Code to external event causing fracture of hip (X590).

A49.-           Bacterial infection of unspecified site

This category INCLUDES infection by bacterial organisms unspecified as to location or disease and not classified elsewhere. Specific disease conditions indicated to have been bacterial in origin are classified to the specified disease rather than to A49. Examples: staphylococcal enteritis is classified to A04.8 and pseudomonas pneumonia is classified to J15.1.

A80.9          Acute poliomyelitis, unspecified

This category INCLUDES poliomyelitis specified as acute unless there is clear indication that death occurred more than one year after the onset of poliomyelitis. It also INCLUDES poliomyelitis not specified as acute if it is clearly indicated that death occurred less than one year after onset of the poliomyelitis. Otherwise, poliomyelitis should be assigned to Sequela of poliomyelitis (B91).

B16             Acute hepatitis B

B17             Other acute viral hepatitis

when reported as the originating antecedent cause of:

K72.1 (Chronic hepatic failure), code B18.-

B20-B24     Human immunodeficiency virus [HIV] disease

Modes of dying, ill-defined and trivial conditions reported as complications of HIV infection should not be linked to categories in B20-B24 and R75, unless there is a specific entry in Volume 3 to that effect.

Conditions classifiable to two or more subcategories of the same category should be coded to the .7 subcategory of the relevant category (B20 or B21).

If a condition classifiable to categories A00-B19, B25-B49, B58-B64, B99, to which sequela rules apply, is mentioned on the record with HIV (B200-B24, R75), use the active phase of the condition in the application of selection and modification rules.

When a blood transfusion is given as treatment for any condition (e.g. a hematological disorder) and an infected blood supply results in a HIV infection, code the HIV as the underlying cause and not the treated condition.

B22.7          HIV disease with multiple diseases classified elsewhere

This subcategory should be used when conditions classifiable to two or more categories from B20-B22 are listed on the certificate.

B34             Viral infection of unspecified site

This category INCLUDES viral infections unspecified as to location or disease and not classified elsewhere. Specific disease conditions indicated to have been viral in origin are classified to the specific disease rather than to B34. Examples: adenovirus enteritis is classified to A082, and acute viral bronchitis is classified to J208.

B95-B97     Bacterial, viral and other infectious agents

Not to be used for underlying cause mortality coding.

C00-D48     Neoplasms

Separate categories are provided for coding malignant primary and secondary neoplasms (C00-C96), Malignant neoplasms of independent (primary) multiple sites (C97), carcinoma in situ (D00-D09), benign neoplasms (D10-D36), and neoplasms of uncertain or unknown behavior (D37-D48). Categories and subcategories within these groups identify sites and/or morphological types.

Morphology describes the type and structure of cells or tissues (histology) as seen under the microscope and the behavior of neoplasms. The ICD classification of neoplasms consists of several major morphological groups (types) including the following:

Carcinomas including squamous cell carcinoma and adenocarcinoma

Sarcomas and other soft tissue tumors including mesotheliomas

Lymphomas including Hodgkin lymphoma and non-Hodgkin lymphoma

Site-specific types (types that indicate the site of the primary neoplasm)

Leukemias

Other specified morphological groups

The morphological types of neoplasms are listed following Chapter XX in Volume 1. They are also described in Volume 3 (the Alphabetical Index) with their morphology code and with an indication as to the coding by site. The morphological code numbers consist of five characters: the first four identify the histological type of the neoplasm and the fifth, following a slash, indicates its behavior. These morphological codes (M codes) are not used by NCHS for coding purposes.

The behavior of a neoplasm is an indication of how it will act. The following terms describe the behavior of neoplasms:

Malignant, primary site (capable of rapid growth   C00-C76,
and of spreading to nearby and distant sites)        C80-C97

Malignant secondary (spread from another            C77-C79
site; metastasis)

In-situ (confined to one site)                               D00-D09

Benign (non-malignant)                                      D10-D36

Uncertain or unknown behavior                           D37-D48
(undetermined whether benign or malignant)

Morphology, behavior, and site must all be considered when coding neoplasms. Always look up the morphological type in the Alphabetical Index before referring to the listing under “Neoplasm” for the site. This may take the form of a reference to the appropriate column in the “Neoplasm” listing in the Index when the morphological type could occur in several organs. For example:

Adenoma, villous (M8261/1) - see Neoplasm, uncertain behavior

Or to a particular part of that listing when the morphological type originates in a particular type of tissue. For example:

Fibromyxoma (M8811/0) - see Neoplasm, connective tissue, benign.

The Index may give the code for the site assumed to be most likely when no site is reported in a morphological type. For example:

Adenocarcinoma

- pseudomucinous (M8470/3)

- - specified site - see Neoplasm, malignant

- - unspecified site C56

Or the Index may give a code to be used regardless of the reported site when the vast majority of neoplasms of that particular morphological type occur in a particular site. For example:

Nephroma (M8960/3) C64

Unless it is specifically indexed, code a morphological term ending in “osis” in the same way as the tumor name to which “osis” has been added is coded. For example, code neuroblastomatosis in the same way as neuroblastoma. However, do not code hemangiomatosis which is specifically indexed to a different category in the same way as hemangioma.

All combinations of the order of prefixes in compound morphological terms are not indexed. For example, the term “chondrofibrosarcoma” does not appear in the Index, but “fibrochondrosarcoma” does. Since the two terms have the same prefixes (in a different order), code the chondrofibrosarcoma the same as fibrochondrosarcoma.

A.  Malignant neoplasms

When a malignant neoplasm is considered to be the underlying cause of death, it is most important to determine the primary site. Morphology and behavior should also be taken into consideration. Cancer is a generic term and may be used for any morphological group, although it is rarely applied to malignant neoplasms of lymphatic, hematopoietic and related tissues. Carcinoma is sometimes used incorrectly as a synonym for cancer. Some death certificates may be ambiguous if there was doubt about the primary site or imprecision in drafting the certificate. In these circumstances, if possible, the certifier should be asked to give clarification.

The categories that have been provided for the classification of malignant neoplasms distinguish between those that are stated or presumed to be primary (originate in) of the particular site or types of tissue involved, those that are stated or presumed to be secondary (deposits, metastasis, or spread from a primary elsewhere) of specified sites, and malignant neoplasms without specification of site.

These categories are the following:

C00-C75          Malignant neoplasms, stated or presumed to be primary, of specified sites and different types of tissue, except lymphoid, hematopoietic, and related tissue

C76                  Malignant neoplasms of other and ill-defined sites

C77-C79          Malignant secondary neoplasm, stated or presumed to be spread from another site, metastases of sites, regardless of morphological type of neoplasm

C80                  Malignant neoplasm of unspecified site (primary) (secondary)

C81-C96          Malignant neoplasms, stated or presumed to be primary, of lymphoid, hematopoietic, and related tissue

C97                  Malignant neoplasms of independent (primary) multiple sites

In order to determine the appropriate code for each reported neoplasm, a number of factors must be taken into account including the morphological type of neoplasm and qualifying terms. Assign malignant neoplasms to the appropriate category for the morphological type of neoplasm, e.g. to the code shown in the Index for the reported term. Morphological types of neoplasm include categories C40-C41, C43, C44, C45, C46, C47, C49, C70-C72, and C80. Specific morphological types include:

C40-C41          Malignant neoplasm of bone and articular cartilage of other and unspecified sites

Osteosarcoma

Osteochondrosarcoma

Osteofibrosarcoma

Any neoplasm cross-referenced as “See also Neoplasm, bone, malignant”

B.  Neoplasm stated to be secondary

Categories C77-C79 include secondary neoplasms of specified sites regardless of the morphological type of the neoplasm. The Index contains a listing of secondary neoplasms of specified sites under “Neoplasm.” If a secondary neoplasm of specified site is reported, code to the morphological type, unless it is a C80 morphological type. If the morphological type is C80, code to the secondary neoplasm.

                                                                                                Code for Record

            I    (a) Secondary carcinoma of intestine                  C785

Code to secondary carcinoma of intestine (C785).

Code to melanoma of unspecified site (C439).

C.  Malignant neoplasms with primary site indicated

If a particular site is indicated as primary, it should be selected, regardless of the position on the certificate or whether in Part I or Part II. If the primary site is stated to be unknown, see Section H. The primary site may be indicated in one of the following ways:

1.  Two or more sites with the same morphology are reported and one site is specified as primary in either Part I or Part II.

                                                                                                Codes for Record

            I    (a) Carcinoma of bladder                                  C791

            II  Primary in kidney                                             C64

Code to malignant neoplasm of kidney (C64).

2.  The specification of other sites as “secondary,” “metastases,” “metastasis,”

“spread” or a statement of “metastasis NOS” or “metastases NOS.”

                                                                                                Codes for Record

            I    (a) Carcinoma of breast                                    C509

                 (b) Secondaries in brain                                    C793

Code to malignant neoplasm of breast (C509), since another site is specified as secondary.

3.  Morphology indicates a primary malignant neoplasm.

If a morphological type implies a primary site, such as hepatoma, consider this as if the word “primary” had been included.

                                                                                                Codes for Record

            I    (a) Metastatic carcinoma                                   C80

                 (b) Pseudomucinous adenocarcinoma                 C56

Code to malignant neoplasm of ovary (C56), since pseudomucinous adenocarcinoma of unspecified site is assigned to the ovary in the Alphabetical Index.

If two or more primary sites or morphologies are indicated, these should be coded according to Sections D, E and G.

D. Independent (primary) multiple sites (C97)

The presence of more than one primary neoplasm could be indicated in one of the following ways:

•  mention of two different anatomical sites

•  two distinct morphological types (e.g. hypernephroma and intraductal carcinoma)

•  by a mix of a morphological type that implies a specific site, plus a second site

It is highly unlikely that one primary would be due to another primary malignant neoplasm except for a group of malignant neoplasms of lymphoid, hematopoietic, and related tissue (C81 - C96), within which, one form of malignancy may terminate in another (e.g. leukemia may follow non-Hodgkin lymphoma).

If two or more sites mentioned in Part I are in the same organ system, see Section E. If the sites are not in the same organ system and there is no indication that any is primary or secondary, code to malignant neoplasms of independent (primary) multiple sites (C97), unless all are classifiable to C81-C96, or one of the sites mentioned is a common site of metastases or the lung (see Section G).

                                                                                                Codes for Record

            I    (a) Cancer of stomach                   3 months      C169

                 (b) Cancer of breast                      1 year           C509

Code to malignant neoplasms of independent (primary) multiple sites (C97), since two different anatomical sites are mentioned and it is unlikely that one primary malignant neoplasm would be due to another.

                                                                                                Codes for Record

            I    (a) Hodgkin disease                                          C819

                 (b) Carcinoma of bladder                                   C679

Code to malignant neoplasms of independent (primary) multiple sites (C97), since two distinct morphological types are mentioned.

                                                                                                Codes for Record

            I    (a) Acute lymphocytic leukemia                          C910

                 (b) Non-Hodgkin lymphoma                              C859

Code to non-Hodgkin lymphoma (C859), since both are classifiable to C81-C96 and the sequence is acceptable.

                                                                                                Codes for Record

            I    (a) Leukemia                                                   C959

                 (b) Non-Hodgkin lymphoma                              C859

                 (c) Carcinoma of ovary                                     C56

Code to malignant neoplasms of independent (primary) multiple sites (C97), since, although two of the neoplasms are classifiable to C81-C96, there is mention of another morphology.

                                                                                                Codes for Record

            I    (a) Leukemia                                                   C959

            II  Carcinoma of breast                                          C509

Code to leukemia (C959) because the carcinoma of breast is in Part II. When dealing with multiple sites, only sites in Part I of the certificate should be considered (see Section E).

E.  Multiple sites

When dealing with multiple sites, generally only sites reported together in Part I or together in Part II of the certificate should be considered except for linkages provided for in the Classification.

If malignant neoplasms of more than one site are entered on the certificate, the site listed as primary should be selected. If there is no indication whether primary or secondary, see Sections C, D and G.

1.       More than one neoplasm of lymphoid, hematopoietic or related tissue

If two or more morphological types of malignant neoplasm occur in lymphoid, hematopoietic or related tissue (C81-C96), code according to the sequence given since these neoplasms sometimes terminate as another entity within C81-C96. Acute exacerbation of, or blastic crisis (acute) in, chronic leukemia should be coded to the chronic form.

                                                                                                Codes for Record

            I    (a) Acute lymphocytic leukemia                         C910

                 (b) Non-Hodgkin lymphoma                              C859

Code to non-Hodgkin lymphoma (C859).

                                                                                                Codes for Record

            I    (a) Acute and chronic lymphocytic leukemia        C910, C911

Code to chronic lymphocytic leukemia (C911).

2.       Multiple sites in the same organ/organ system

Malignant neoplasm categories providing for overlapping sites designated by .8 are not used unless a site is specifically indexed to one of these categories, e.g. anorectum cancer.

If the sites mentioned are in the same organ/organ system .9 subcategories should be used. This applies when the certificate describes the sites as one site “and” another or if the sites are mentioned on separate lines. If one or more of the sites reported is a common site of metastases, see Section G.

a.  If there is mention of two subsites in the same organ, code to the .9 subcategory of that three-character category.

                                                                                                Codes for Record

            I    (a) Carcinoma of descending colon and sigmoid   C186 C187

Code to malignant neoplasm of colon (C189) since both sites are subsites of the same organ.

                                                                                                Codes for Record

            I    (a) Carcinoma of head of pancreas                     C250

                 (b) Carcinoma of tail of pancreas                       C252

Code to malignant neoplasm of pancreas, unspecified (C259) since both sites are subsites of the same organ.

b.  If two or more sites are mentioned and all are in the same organ system, code to the .9 subcategory of that organ system, as in the following list:

C150-C269             Digestive system
C300-C399             Respiratory system
C400-C419             Bone and articular cartilage of limbs, other and unspecified sites
C490-C499             Connective and soft tissue

C73-C759               Thyroid and other endocrine glands

                                                                                                Codes for Record

            I    (a) Pulmonary embolism                                   I269

                 (b) Cancer of stomach                                       C169

                 (c) Cancer of gallbladder                                    C23

Code to ill-defined sites within the digestive system (C269). Stomach and gallbladder are in the same organ system and reported together in the same part.

                                                                                                Codes for Record

            I    (a) Carcinoma of vagina and cervix                     C52 C539

Code to malignant neoplasm of female genital organs (C579). Vagina and cervix are in the same organ system and are reported together in the same part.

c.  If there is no available .9 subcategory or different organ systems are reported, code to malignant neoplasms of independent (primary) multiple sites (C97).

                                                                                                Codes for Record

            I    (a) Cardiac arrest                                             I469

                 (b) Carcinoma of prostate and bladder                C61 C679

Code to malignant neoplasms of independent (primary) multiple sites (C97), since there is no available .9 subcategory.

d.  Although, generally linkages only apply to Part 1, the Classification provides linkages for certain sites when reported anywhere on the certificate.

                                                                                                Codes for Record

            I    (a) Carcinoma of esophagus                              C159

                 (b)

                 (c)

G. Metastatic neoplasm

When a malignant neoplasm spreads or metastasizes it generally retains the same morphology even though it may become less differentiated. Some metastases have such a characteristic microscopic appearance that the pathologist can infer the primary site with confidence, e.g. thyroid. Widespread metastasis of a carcinoma is often called carcinomatosis. The adjective “metastatic” is used in two ways - sometimes meaning a secondary from a primary elsewhere and sometimes denoting a primary that has given rise to metastases. Neoplasms qualified as metastatic are always malignant, either primary or secondary.

Although malignant cells can metastasize anywhere in the body, certain sites are more common than others and must be treated differently (see list of common sites of metastases). However, if one of these sites appears alone on a death certificate and is not qualified by the word “metastatic,” it should be considered primary.

Common sites of metastases

Bone                                              Lymph nodes

Brain                                             Mediastinum 

Central nervous system                            Meninges

Diaphragm                                         Peritoneum

Code to primary cancer of brain since it is reported alone on the certificate.

  Special instruction: lung

The lung poses special problems in that it is a common site for both metastases and primary malignant neoplasms. Lung should be considered as a common site of metastases whenever it appears in Part I with sites not on this list. If lung is mentioned anywhere on the certificate and the only other sites are on the list of common sites of metastases, consider lung primary. However, when the bronchus or bronchogenic cancer is mentioned, this neoplasm should be considered primary.

                                                                                                Code for Record

            I    (a) Carcinoma of lung                                       C349

If the statement, “primary site unknown,” or its equivalent, appears anywhere on a certificate, code to the category for unspecified site for the morphological type involved (e.g. adenocarcinoma C80, fibrosarcoma C499, osteosarcoma C419), regardless of the site(s) mentioned elsewhere on the certificate.

Consider the following terms as equivalent to “primary site unknown”:

? Origin (Questionable origin)

? Primary (Questionable primary)

? Site (Questionable site)

? Source (Questionable source)

Undetermined origin

Undetermined primary

Undetermined site

Undetermined source

Unknown origin

Code to malignant melanoma of unspecified site (C439).

NOTE:      When "primary site unknown" or its equivalent appears on the certificate and a doubtful expression such as presumed or probably is reported qualifying a specific site(s), interpret the primary to be the site(s) following the doubtful qualifying expression and code as primary.

            I    (a) Cancer unk primary, presumed lung              C349

Code to primary lung cancer (C349).

I.  Sites with prefixes or imprecise definitions

Neoplasms of sites prefixed by “peri,” “para,” “pre,” “supra,” “infra,” etc. or described as in the “area” or “region” of a site, unless these terms are specifically indexed, should be coded as follows: for morphological types classifiable to one of the categories C40, C41 (bone and articular cartilage), C43 (malignant melanoma of skin), C44 (other malignant neoplasms of skin), C45 (mesothelioma), C47 (peripheral nerves and autonomic nervous system), and C49 (connective and soft tissue), C70 (meninges), C71 (brain), and C72 (other parts of central nervous system), code to the appropriate subdivision of that category; otherwise code to the appropriate subdivision of C76 (other and ill-defined sites).

                                                                                                Code for Record

J.  Doubtful diagnosis

Malignant neoplasms described as one site “or” another, or if “or” is implied, should be coded to the category that embraces both sites. If no appropriate category exists, code to the unspecified site of the morphological type involved. This rule applies to all sites whether they are on the list of common sites of metastases or not.

            I    (a) Carcinoma of ascending or descending colon

Code to malignant neoplasm of colon, unspecified (C189).

            I    (a) Osteosarcoma of lumbar vertebrae or sacrum

K.  Malignant neoplasms of unspecified site with other reported conditions

When the site of a primary malignant neoplasm is not specified, no assumption of the site should be made from the location of other reported conditions such as perforation, obstruction, or hemorrhage. These conditions may arise in sites unrelated to the neoplasm, e.g. intestinal obstruction may be caused by the spread of an ovarian malignancy.

Code to rheumatic mitral insufficiency (I051). Rheumatic endocarditis, selected by the General Principle, links (LMP) with rheumatic mitral insufficiency. The mitral insufficiency is coded as rheumatic since it is reported with a heart disease specified as rheumatic.

B.   When a condition listed in category I50.- is indicated to be “due to” rheumatic fever and there is no mention of another heart disease that is classifiable as rheumatic, consider the condition in I50.- to be described as rheumatic.

.                                                                                              Codes for Record

            I    (a) Heart failure                                               I099

                 (b) Rheumatic fever                                          I00

                 (b) Aortic stenosis                                            I060

Code to disorders of both aortic and tricuspid valves (I082). Conditions of both valves are considered as rheumatic since the diseases of the aortic and the tricuspid valves are jointly reported.

D.   When mitral insufficiency, incompetence, or regurgitation are jointly reported with mitral stenosis NOS (or synonym), code all these conditions as rheumatic unless there are indications to the contrary.

                                                                                                Codes for Record

            I    (a) Mitral stenosis                                             I050

I01.-           Rheumatic fever with heart involvement

This category INCLUDES active rheumatic heart disease. If there is no statement that the rheumatic process was active at the time of death, assume activity (I010-I019) for each rheumatic heart disease (I050-I099) on the certificate in any one of the following situations:

A.   Rheumatic fever or any rheumatic heart disease is stated to be active or recurrent.

                                                                                                Codes for Record

            I    (a) Mitral stenosis                                             I011

                 (b) Active rheumatic myocarditis                        I012

Code to other acute rheumatic heart disease (I018). Active rheumatic mitral stenosis is classified to I011 when it is reported with an active rheumatic heart disease. Therefore, the underlying cause is I018 since this category includes multiple types of heart involvement.

B.   The duration of rheumatic fever is less than 1 year.

                                                                                                Codes for Record

I34.0-I38    Valvular diseases not indicated to be rheumatic

A.   In the Classification, certain valvular diseases, i.e., disease of mitral valve (except insufficiency, incompetence, and regurgitation without stenosis) and disease of tricuspid valve are included in the rheumatic categories even though not indicated to be rheumatic. This classification is based on the assumption that the vast majority of such diseases are rheumatic in origin.

Do not use these diseases to qualify other heart diseases as rheumatic. Code these diseases as nonrheumatic if reported due to one of the nonrheumatic causes on the following list:

When valvular heart disease (I050-I079, I089 and I090) not stated to be rheumatic is reported due to:

A1690         C73-C759       E804-E806      J030

B.   Consider diseases of the aortic, mitral, and tricuspid valves to be nonrheumatic if they are reported on the same line due to a nonrheumatic cause in the previous list. Similarly, consider diseases of these three valves to be nonrheumatic if any of them are reported due to the other and that one, in turn, is reported due to a nonrheumatic cause in the previous list.

O00-O99     Pregnancy, childbirth, and the puerperium

Conditions classifiable to categories O00-O99 are limited to deaths of females of childbearing age. Some of the maternal conditions are also the cause of death in newborn infants. Always refer to the age and sex of the decedent before assigning a condition to O00-O99.

Obstetric deaths are classified according to time elapsed between the obstetric event and the death of the woman:

O95            Obstetric death of unspecified cause

O960-O969  Death from any obstetric cause occurring more than 42 days but less than one year after delivery

O970-O979  Death from sequela of obstetric causes (death occurring one year or more after delivery)

The standard certificate of death contains a separate item regarding pregnancy. Any positive response to one of the following items should be taken into consideration when coding pregnancy related deaths.

       Pregnant at time of death

       Not pregnant, but pregnant within 42 days of death

       Not pregnant, but pregnant 43 days to 1 year before death

 

If one of the options from the previous list is marked and the decedent is greater than 44 years old, code as a pregnancy record only when there is a condition reported which indicates the person was pregnant either at the time of death or pregnant 43 days to 1 year before death.

Additionally, if the third option is checked, but there is a maternal condition reported with a duration that indicates the pregnancy was within 42 days of death, disregard the checkbox and prefer the duration.

 

The following are valid single character codes used in the separate checkbox item regarding pregnancy on some variations of the standard death certificate. These codes are to be taken into consideration when coding pregnancy related deaths.

1 - Not pregnant within the past year

2 - Pregnant at the time of death

3 - Not pregnant, but pregnant within 42 days of death

4 - Not pregnant, but pregnant 43 days to 1 year before death

7 - Not on certificate

8 - Not applicable

9 - Unknown

 

Consider the pregnancy to have terminated 42 days or less prior to death unless a specified length of time is written in by the certifier. Take into consideration the length of time elapsed between pregnancy and death if reported as more than 42 days.

If an indirect maternal cause is selected as the originating antecedent cause, reselect any direct maternal cause on the line immediately above the indirect cause. If no direct cause is reported, the indirect cause will be accepted as the cause of death.

1.  Checkbox only

If the only indication of pregnancy is in the checkbox, convert the condition selected as the underlying cause to the relevant maternal category.

            I    (a) Rheumatic heart disease                                 I099

                 (b)

                  Pregnancy: Pregnant at time of death

Code to O994. Convert the condition selected as the underlying cause (I099) to the relevant maternal category. Pregnancy checkbox is marked 2 so use the state (pregnancy) as a lead term and follow the index: Pregnancy, complicated by, conditions NEC in I00-I09.

            I    (a) Right heart failure                                          I500

                 (b) Pulmonary hypertension                                  I272

                  Pregnancy: Not pregnant, but pregnant 43 days to 1 year before death

Code to O961. Convert the condition selected as the underlying cause (I272) to the relevant maternal category. Pregnancy checkbox is marked 4 so assign O96.-. Follow the index to find the current pregnancy code O994 (Pregnancy, complicated by, conditions NEC in I20-I461). Since the current maternal code would be indirect, assign the fourth digit to 1.

            I    (a) Pulmonary embolism                                      I269

                 (b) Right heart failure                                          I500

                  Pregnancy: Not pregnant, but pregnant within 42 days of death

Code to O994. Convert the condition selected as the underlying cause (I500) to the relevant maternal category. Pregnancy checkbox is marked 3 so code as indexed under Pregnancy, complicated by, conditions NEC in I470-I958.

O08.-          Complications following abortion and ectopic and molar pregnancy

Not to be used for underlying cause mortality coding. Use categories O00-O07.

Not to be used for underlying cause mortality coding. If no other cause of maternal mortality is reported, code to Obstetric death of unspecified cause (O95).

O81-O84     Method of delivery

Not to be used for underlying cause mortality coding. If no other cause of maternal mortality is reported, code to Complication of labor and delivery, unspecified (O759).

P07.-           Disorders related to short gestation and low birth weight, not elsewhere classified

P08.-           Disorders related to long gestation and high birth weight

Not to be used if any other cause of perinatal mortality is reported. This does not apply if the only other cause of perinatal mortality reported is respiratory failure of newborn (P28.5).

P70.3-P72.0         Transitory endocrine and metabolic disorders specific to fetus and

P72.2-P74.9         newborn

Not to be used for underlying cause mortality coding. If no other perinatal cause of mortality is reported, code to Condition originating in the perinatal period, unspecified (P96.9). If another perinatal cause is reported, prefer this cause. If more than one perinatal cause is reported, apply the rules for conflict in linkage in selection of the other perinatal cause.

P95             Fetal death of unspecified cause

Not to be used for underlying cause mortality coding. Use P96.9 for fetal death in mortality coding.

Q44.6          Cystic disease of liver

with mention of:

Q61.1-Q61.3      (Polycystic kidney disease), code Q61.1-Q61.3

R69.-          Unknown and unspecified causes of morbidity

Not to be used for underlying cause mortality coding. Use R95-R99 as appropriate.

S00-T98      Injury, poisoning, and certain other consequences of external causes

Not to be used for underlying cause mortality coding.

V01-Y89     Classification of external causes of morbidity and mortality

The codes for external causes permit the classification of environmental events and circumstances as the cause of injury, poisoning and other adverse effects.

1.  Successive external causes. Where successive external events occur and cause death, assignment is to the initiating event except where this was a trivial accident leading to a more serious one. In the latter case, the trivial event may be disregarded.

 

2. Slight injuries. When a slight injury is involved as a cause of death, the Rules for Selection are applied. Slight injuries are trivial conditions rarely causing death unless a more serious condition such as tetanus resulted from the slight injury. Therefore, where a slight injury is selected, Rule B, Trivial conditions, is usually applied. For the purpose of these rules, slight injuries comprise superficial injuries such as:

 

abrasions                    exposure NOS

bite of insect               minor cut

          (non-venomous)     prick

blister                      puncture except trunk

bruise                       scratch

burn of first degree         splinter

contusion (external)

 

 

 

For slight injury resulting in streptococcal septicemia, septicemia, or erysipelas refer to Section IV, B, categories A40.-, A41.-, A46.

 

3.  Accident information entered in space outside Part I and Part II. When information concerning an accident is reported only in a space specifically provided for such information outside of Parts I and II of the Medical Certification Section, inquiry should be made concerning the relationship of the accident to the death and to the other causes reported. If no information is received from the inquiry, the assignment is made by application of the Rules for Selection to the causes reported in Parts I and II.

 

4.  Accident due to disease condition. When a disease condition, such as cerebral hemorrhage, heart attack, diabetic coma, or alcoholism is indicated by the certifier to be the underlying cause of an accident, the assignment is made to the accidental cause unless there is evidence that the death occurred prior to the accident. Thus, accidents are generally not accepted due to disease conditions. However, there are some exceptions to this concept:

a.  asphyxia from aspiration of mucus or vomitus as a result of a disease condition

b.  a fall from a pathological fracture or disease of the bone

c.  aspiration of milk or other food due to diseases which presumably affect the ability to control the process of swallowing, for example, cancer of the throat or a disease resulting in paralysis

d.  accidents resulting from epilepsy (G40-G41)

 

5.  Found injured on highway. See category V892 in Volume 1.

 

6.  Complication of trauma for purposes of applying Selection Rule 3. Refer to Section II, Selection Rule 3, Direct Sequel.

 

7.  Selecting external causes as the underlying cause. External causes will be coded as the underlying cause even though a Chapter XIX code is not reported. When selecting the sequence responsible for death, no preference is given to the external cause. Apply selection and modification rules in the usual way.

 

8.  Use of the Index and Tabular List. ICD-10 provides separate indexing in Volume 3, Section II for the external causes of injury, with frequent references to Volume 1. The External Causes of Injury Index provides a double axis of indexing—descriptions of the circumstances under which the accident or violence occurred and the agent involved in the occurrence. Usually, the “lead terms” in the External Causes of Injury Index describe the circumstances of the injury with a secondary (indented) entry naming the agent involved.

                                                  Code for Term

Fall from building                        W13

Locate the E-code for “fall”:

Fall

- from

- - building W13.-

After locating the external cause code in the Index, always refer to Volume 1 since certain external cause codes require a fourth character.

The ICD provides a fourth character for use with categories W00 - Y34, except Y06.- and Y07.-, to identify the place of occurrence of the external cause. NCHS uses a separate field for this purpose. Only the three-character category codes are assigned in underlying cause coding.

                                                    Code for Term

House fire                                     X00

Locate the E-code for “House fire”:

House fire (uncontrolled) X00.-

V01-V99     Transportation Accidents

1.  General Instructions

The main axis of classification for land transports (V01-V89) is the victim’s mode of transportation. The vehicle of which the injured person is an occupant is identified in the first two characters since it is seen as the most important for prevention purposes.

Definitions and examples relating to transport accidents are in Volume 1, Chp. XX. Refer to these definitions when any means of transportation (aircraft and spacecraft, watercraft, motor vehicle, railway, other road vehicle) is involved in causing death.

For classification purposes, a motor vehicle not otherwise specified is NOT equivalent to a car. Motor vehicle accidents where the type of vehicle is unspecified are classified to V87-V89.

A vehicle not otherwise specified is NOT equivalent to a motor vehicle unless the accident occurred on the street, highway, road(way), etc. Vehicle accidents where the type of vehicle is unspecified are classified to V87-V89.

Additional information about type of transports is given below:

a.  Car (automobile) includes blazer, jeep, minivan, sport utility vehicle

b.  Pick-up truck or van includes ambulance, motor home, truck (farm) (utility)

c.  Heavy transport vehicle includes armored car, dump truck, fire truck, panel truck, semi, tow truck, tractor-trailer, 18-wheeler

2.  Use of the Index and tabular list

ICD-10 provides a Table of land transport accidents in Volume 3, Section II. This table is referenced with any land transport accident if the mode of transportation is known. Since the Index does not always provide a complete code, reference to Volume 1, Chapter XX is required.

For V01-V09, the fourth character indicates whether a pedestrian was injured in a nontraffic accident, traffic accident, or unspecified whether traffic or nontraffic accident.

For V10-V79, the fourth character represents the status of the victim, i.e., whether the decedent was driver, passenger, etc. For each means of transportation, there is a different set of fourth characters. Each means of transportation is preceded by its set of fourth characters in Volume 1.

                                                          Code for Term

  Car overturned, killing driver                   V485

In the Index, refer to:

Overturning

- transport vehicle NEC (see also Accident, transport) V89.9

Accident

- transport (involving injury to) (see also Table of land transport accidents) V99

In the Table of land transport accidents, select the intersection of:

Under Victim and mode of transport, select
Occupant of:

- car (automobile)

Under In Collision with or involved in: select
Noncollision transport accident

The code is V48.-. From Volume 1 the fourth character is 5, driver injured in traffic accident.

                                                          Code for Term

  Auto collision with animal                       V409

In the Index, refer to:
Collision (accidental) NEC (see also Accident, transport) V89.9

Accident
- transport (involving injury to) (see also Table of land transport accidents) V99

In the Table of land transport accidents, select the intersection of:

Under Victim and mode of transport, select
Occupant of:
- car (automobile)

Under In collision with or involved in: select
Pedestrian or animal

The code is V40.-. From Volume 1, determine the fourth character is 9, unspecified car occupant injured in traffic accident.

3.  Classifying accidents as traffic or nontraffic

If an event is unspecified as to whether it is a traffic or nontraffic accident, it is assumed to be:

a.  A traffic accident when the event is classifiable to categories V02-V04, V10-V82, and V87.

b.  A nontraffic accident when the event is classifiable to categories V83-V86. These vehicles are designed primarily for off-road use.

c.  Consider category V05 to be unspecified whether traffic or nontraffic if no place is indicated or if the place is railroad (tracks).

d.  Consider category V05 to be traffic if place is railway crossing.

e.  Consider accidents involving occupants of motor vehicles as traffic when the place is railroad (tracks).

X30-X39     Exposure to forces of nature

These categories INCLUDE accidents resulting directly from forces over which man has no control, but EXCLUDES those resulting indirectly through a second event which is classified to the causative agent involved in the subsequent accident.

General Guidelines when coding cataclysms:

-Use these categories for deaths resulting from direct effects of the storm

-Do not use these categories for deaths resulting from a second event, such as clean-up after a cataclysmic event.

-When hurricane, storm, etc is reported, consider references to power failure, loss of power, lack of air conditioning, etc as part of the storm and not a subsequent accident.

-Code wildfire as X01, Exposure to uncontrolled fire, not in building or structure.

X40-X49     Accidental poisoning by and exposure to noxious substances

1.  Poisoning by drugs

a.  When the following statements are reported, see Table of drugs and chemicals for the external cause code and code as accidental poisoning unless otherwise indicated.

Interpret all these statements to mean poisoning by drug and code as poisoning whether or not the drug was given in treatment:

drug taken inadvertently
lethal (amount) (dose) (quantity) of a drug
overdose of drug
poisoning by a drug
toxic effects of a drug
toxic reaction to a drug

Natural

Code to X64, interpreting as suicide since MOD is natural.

c.  When components of combinations of medicinal agents classifiable to X40-X44 are involved, proceed as follows:

(1) When accidental poisoning from a single drug is reported in Part I with a combination of drugs in Part II, code the external cause code for the drug reported in Part I.

 

                                                                                                                   Codes for Record

            I    (a) Acute barbiturate intoxication                                          T423 X41

            II Accident - Took unknown amount of barbiturates and aspirin    T423 T390

Code to X41, accidental poisoning by barbiturates since certifier indicated this drug was the cause of death.

(2) When accidental poisoning by a combination of drugs classified to different external cause codes is reported and (1) does not apply, code the external cause code to X44, accidental poisoning and exposure to other and unspecified drugs, medicaments, and biological substances. Note that this applies to accidental manner of death only. Use the following codes for the different manners of death: Suicide X64, Homicide X85 and Undetermined Y14. Note that this does not apply to chemicals such as carbon monoxide and acetone.

                                                                                                Codes for Record

            I    (a) Drug intoxication                                        T509  X44

                 (b) Digitalis & cocaine intoxication                     T460 T405

            I    (a) Alcohol and barbiturate intoxication              T519 X45 T423 X41

Code to X41, accidental poisoning by and exposure to antiepileptic, sedative-hypnotic, antiparkinsonism and psychotropic drugs, not elsewhere classified. Alcoholic intoxication or poisoning reported in combination with medicinal agents is classified to poisoning by the medicinal agents.

EXCEPTION: When alcohol poisoning is reported in Part I and drug poisoning in Part II, code to the alcohol.

                                                                                                Codes for Record

            I    (a) Poisoning by alcohol                                   T519 X45

                 (b)

            II   Toxic levels of heroin and flunitrazepam             T401 X44 T424

2.  Carbon monoxide poisoning

Code carbon monoxide poisoning from motor vehicle exhaust gas to noncollision motor vehicle accident (traffic) according to type of motor vehicle involved unless there is indication the motor vehicle was not in transit. Consider statements of “sleeping in car,” “sitting in car,” “in parked car” or place stated as “garage” to indicate the motor vehicle was “not in transit.” Assume “not in transit” in self-harm (intentional) and self-inflicted cases.

X60-X84     Intentional self-harm

The categories X60-X84 include intentionally self-inflicted poisoning or injury as well as deaths specified as suicide (attempted). The codes are indexed under the event as well as under “Suicide” in the External causes of injury index.

                                                                                                Codes for Record

            I    (a) Hanging                                                     T71 X70

Code to intentional self-harm by hanging, strangulation and suffocation (X70).

X85-Y09 Assault

The categories X85-Y09 include injuries inflicted by another person with intent to injure or kill by any means as well as deaths specified as homicide. The codes are indexed under the event as well as under “Assault” in the External causes of injury index.

When the manner of death block is marked as Homicide but the certifier specifies Accident elsewhere on the certificate, code as Accident. The definition of homicide as "death at the hands of another" may lead certifiers to mark Homicide in the checkbox when really the death itself was unintentional.

Words like deliberately, intentionally, purposefully or assault can be interpreted as intentional and coded as homicide.

                                                                                                Codes for Record

2.  Deaths at ages under 18 years for which the cause of death certification specifies homicide and an injury occurring as an isolated episode, with no indication of previous mistreatment, should not be classified to Y070-Y079. This excludes from Y070-Y079 deaths due to injuries specified to be the result of events such as shooting, stabbing, hanging, fighting, or involvement in robbery or other crime, because it cannot be assumed that such injuries were inflicted simply in the course of punishment or cruel treatment.

                      Female, 1 year                                                      Codes for Record

Y40-Y59     Drugs, medicaments and biological substances causing adverse effects in therapeutic use

1.  Condition due to (named) drug or drug therapy

When a condition is reported due to a (named) drug or drug therapy, consider the condition to be a complication of a correct drug and medicinal substance properly administered providing the sequence is acceptable. This instruction also includes a condition reported due to drug use or named drug use unless:

•  The drug is one which is not used for medical purposes, e.g., LSD or heroin.

or

•  It was an analgesic, sedative, narcotic or psychotropic drug (or combination thereof) or drug NOS

AND the certifier indicated the death was due to an “accident”, “suicide”, or it occurred under “undetermined circumstances,”

or

•  One or more of these drugs was taken in conjunction with alcohol

If one of the exceptions apply, code to poisoning (refer to Section IV, B, X40-X49). Use the following instructions to select the correct underlying cause if a condition is reported due to a (named) drug or drug therapy.

a.  If the condition for which the drug is being administered is stated, code this condition as the underlying cause applying any appropriate modification rule(s).

When a sequence of conditions involving an operation is responsible for a death, the cause for which the operation was performed is coded, unless it is the result of another condition. In the latter case, the original cause is coded. If the reason for the operation is not stated or implied, select the external cause code for the operation as the underlying cause. However, when selecting the sequence responsible for death, no preference is given because an operation was involved.

If a term denoting an operation is selected as the cause of death without mention of the condition for which it was performed, or of the findings of the operation, and the Index provides no assignment for it:

1.  It is assumed that the condition for which the operation is usually performed was present and assignment will be made in accordance with the rules for selection of the cause of death (e.g. code “appendectomy” to K37).

2.  However, if the name of the operation leaves in doubt what specific morbid condition was present, additional information is to be sought.

3.  If there is no further information concerning the condition for which the surgery was performed, code to the residual category for disease of the site indicated by the name of the operation. Do not assume a disease condition for other medical care.

4.  When neither the organ nor the site is indicated in the operative term, code the appropriate external cause code for the surgery.

5.  If the reason for the operation is not stated or implied, code the appropriate external cause code for the surgery.

6.  When the only reported condition indicates an operation and the record cannot be classified by the previous instructions, code to “Other ill-defined and unspecified causes of mortality” (R99).

These procedures include:

amputation              pelvic exenteration

arteriovenous shunt     portocaval shunt

chordotomy              radical neck dissection

craniotomy              rhizotomy

cystostomy              sympathectomy

If one of these types of procedures is the only entry on the certificate, code R99.

7.  For complications of operations for purposes of applying Rule 3, Direct sequel, refer to Section II, Selection Rule 3.

Y84             Other medical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of procedure.

This category is not to be used if the reason for treatment is indicated. However, do not assume a condition for the reason medical care was administered.

Y60-Y69     Misadventures to patients during surgical and medical care

These categories are limited to deaths explicitly indicated to be the result of an error or accident during medical care. These categories are not to be used if the condition requiring treatment is indicated. When the condition requiring treatment is not stated or implied, code the underlying cause to Y60-Y69. This does not apply when serum hepatitis is reported as a complication of blood transfusion, in this case code the underlying cause to serum hepatitis provided the reason for treatment is not reported.

Y85-Y89     Sequela of external causes of morbidity and mortality

A sequela is a late effect, an after effect, or a residual of a nature of injury or external cause. The Classification provides categories Y850-Y899 for sequela of external causes. If either the nature of injury or the external cause requires a sequela code, the selected external cause must be coded to a sequela category. Use the following guidelines to determine when the external cause should be coded to a sequela category.

Y850  Sequela of motor vehicle accident (includes V01-V89)

Y859  Sequela of other and unspecified transport accidents (includes V90-V99)
