SECTION V – EFFECTS OF EXTERNAL CAUSE OF INJURY AND EXTERNAL CAUSES OF INJURY AND POISONING

In ICD-10, the Nature of Injury Chapter (XIX) is part of the main Classification but certain effects of external causes are classified in Chapters I-XVIII. The external cause codes (Chapter XX) are intended for use, where relevant, to identify the external cause of conditions classifiable to Chapters I-XVIII, as well as to Chapter XIX. While not all external causes will have a corresponding code in Chapter XIX, an external cause code is required when a code from Chapter XIX is applicable.

A. External cause code (E-Code) concept

An external cause of injury may be classified to Accidents (V01-X59), Intentional self harm (X60-X84), Assault (X85-Y09), Event of undetermined intent (Y10-Y34), Legal intervention and operations of war (Y35-Y36), Complications of medical and surgical care (Y40-Y84), and Sequela of external causes (Y85-Y89). When unspecified, assume all external cause one-term entities to be accidental unless the External Causes of Injury Index provides otherwise.

The objective in assigning the external cause codes is to combine into the entity being coded any related entries on the record that will permit the assignment of the most specific external cause codes in accordance with the intent of the certifier. After the determination of the most specific external cause code is made, enter this code where it is first encountered on the record. Do not repeat the same external cause code when it is reported on other lines. When more than one external cause is reported, code each external cause code where it is first encountered on the certificate.

The death certificate provides a specific place for information concerning the external cause of injury that is usually entered on the lines below the line labeled “Part II.” However, a description of the external cause is reported frequently in Part I and may be repeated in the space provided for this information.

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. For all other manners of death, if there is more than one reported, code as could not be determined.

When such statements as: “jumped or fell,” “don’t know,” “accident or suicide,” “accident or homicide,” “undetermined,” or “open verdict” are reported, code the external cause as “undetermined.” The “undetermined” categories include self-inflicted injuries, except poisoning, when not specified whether accidental or with intent to harm.

1. Use of Index

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.

Fall from building W13

Locate the E-code for “fall”:

Fall, falling

– from, off

– – building W13.-

2. Use of Tabular List

After locating the external cause code in the Index, always refer to Volume 1 since certain external cause codes for transport accidents require a fourth character not provided for in the Index. When ICD-10 provides a fourth character subcategory for an external cause code, always code the fourth character.

Fell from boat V929

Locate the E-code for “fall”:

Fall

– from

– – boat, ship, watercraft NEC (with drowning or submersion) V92.-

In Volume 1, the fourth character describes the type of boat. Code the fourth character “9,” unspecified watercraft.

The Classification 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 multiple cause coding.

House fire X00

Locate the E-code for “House fire”:

House Fire (uncontrolled) X00.-

In Volume 1, a fourth character identifying the place of occurrence is required. Assign code 0 (home) to the place of occurrence variable in the field provided for this variable.

3. Place of occurrence of external cause

Enter a one-character place of occurrence code (0-9), for external causes of injury classifiable to W00-Y34, except Y06.- and Y07.-, if the effects of the external cause are classifiable to Chapter XIX. Do not enter a place code for external causes classifiable to any other external cause code. Use only the information reported in the medical certification section of the death certificate or additional information (AI) to determine the place code. Refer to Appendix D for the list of place of occurrence codes.

4. Manner of death (Item 37) on death certificate

Affecting multiple cause codes

(1) When separate check boxes for indicating whether an external cause was accidental, suicidal, homicidal, undetermined, or pending investigation appear on the medical certification form, treat the check box entry as a one-term entity.

(2) When “accident,” “pending,” “unknown,” or “undetermined” is written in the “check box” or is one of the items checked and no condition is coded to Chapter XIX, disregard the check box entry for assignment of codes.

(3) When “suicide” or “homicide” is written in the “check box”, or is one of the items checked and no condition is coded to Chapter XIX, assign the appropriate external cause code preceded by Injury NOS, T149.

(4) When “unknown” or “open verdict” is written in the check box and there is a condition(s) coded to Chapter XIX, code the external cause to the appropriate “event of undetermined intent” category.

(5) When “pending,” “pending investigation,” “deferred,” or “unclassified” is reported in the check box and there is a condition(s) coded to Chapter XIX, code the external cause as indexed.

(6) Enter a code for an entry in a check box for “natural cause” only if this is the only codable entry on the certificate or the only other codable entry is “unknown cause” (R97).

As a separate variable

Enter an alpha character manner of death code (N, A, S, H, P, or C) in the appropriate data position for any entry in the manner of death check box. Use only the information reported in the manner of death box to assign the code.

Code the manner of death as:

Natural………………………………… N

Accident………………………………. A

Suicide…………………………………. S

Homicide……………………………… H

Pending Investigation……………… P

Could not be determined………….. C

Blank…………………………………… Blank

5. Nature of injury and external cause code lists

Since certain entities state or imply cause (E-code) and effect (N-code), ICD-10 provides both N-codes and E-codes for many terms. Determination must be made whether to code nature of injury code only, external cause code only, or both nature of injury and external cause codes for such terms. Use the following lists as guides in classifying these terms. When ICD-10 provides a nature of injury code for an entity that does not appear on either list, use the nature of injury code only.

The E-code is only coded the first time external information is mentioned. A term requiring a N-code is coded each time it is reported.

Nature of injury code only (N-Code)

Allergy Intoxication when due to a

Anaphylactic reaction drug

Anaphylactic shock Lacerations

B. Placement of nature of injury and external cause codes

When a nature of injury code and an external cause code are required for an entity, enter the nature of injury code followed by the external cause code on the same line.

Place I (a) Gunshot wound of chest S219 &W34

9 (b)

(c)

MOD II

A

Accident

Since “gunshot wound” requires a nature of injury and an E-code, enter on I(a) the nature of injury code for wound of chest followed by the most specific E-code for gunshot, accidental. Code place of occurrence as 9 (unspecified). Code manner of death as A (accident).

When entries requiring nature of injury codes and external cause codes are reported on the same line in Part I, code the first nature of injury code followed by the most specific external cause code; then code any remaining conditions for the line in the order indicated by the certifier.

Place I (a) Laceration of throat S118

9 (b) Dog bite of shoulder, S410 &W54 T111 S119

(c) arm and neck

Code the nature of injury code only for I(a). On I(b), code the nature of injury code for “bite of shoulder” followed by the E-code for dog bite followed by the remaining nature of injury codes for “bite arm and neck.” Code place of occurrence as 9 (unspecified).

Place I (a) Fracture skull S029

9 (b) Fell from window, crushed S280 &W13 S381

(c) chest and abdomen

I(a) requires a nature of injury code only. I(b) requires both nature of injury and E-code since the external cause and injuries are reported on this line. Code first nature of injury code followed by the external cause code, followed by the remaining nature of injury codes. Code place of occurrence as 9 (unspecified).

Place I (a) Renal failure N19

0 (b) Injury kidney, liver and S370 &W11 S361 S360

(c) spleen. Fell from ladder at home

Code I(b) injury kidney followed by external cause code for the fall, followed by the remaining injuries. Code place of occurrence as 0 (home).

Place I (a) Cerebral laceration & contusion S062

9 (b) Blow to right temporal area &X599

Code I(a) to the nature of injury code only, and I(b) to the external cause code only. Code place of occurrence as 9 (unspecified).

In Part II, code each entry in the same order as entered on the certificate. For entities requiring both nature of injury and external cause codes, enter the nature of injury code followed by the external cause code. Enter the information recorded in the special spaces that have been provided on the medical certification form for recording information about external causes of injury following any codes that are applicable to Part II.

Place I (a) Crushed chest S280

9 (b) Broken rib S223

(c)

II Fracture hip and arm S720 T10 &W24

43 Run over by a forklift

In Part II, code each entry in the order entered on the certificate. Code place of occurrence as 9 (unspecified).

Place I (a) Subdural hematoma S065

9 II Blunt impact injury to head S099 &Y00

MOD

H

Homicide

43 Struck on head with a blunt object by another person

Since the entry in Part II requires both nature of injury and external cause codes, enter the nature of injury code followed by the most specific external cause code. Code place of occurrence as 9 (unspecified).

Place I (a) Head wound S019

9 II &W34 S062 S019

MOD

A

Accident

43 Cerebral laceration, GSW of head

Code external cause code first in Part II since manner of death box requires an external cause code. Code place of occurrence as 9 (unspecified).

C. Use of ampersand

Use an ampersand to identify the following
The most specific external cause code causing injuries or poisoning.
Certain localized effects of poisonous substances (X45-X49) or aspiration (W78,W79, W80) when classifiable to Chapters I-XVIII.
Ampersand the E-code for aspiration (W78-W80) anytime it is reported.

Place I (a) Aspiration T179 &W78

0 (b) Vomitus

II Fx Hip Fall at home S720 &W19

Ampersand both the E-code for aspiration and the E-code for fall at home.

Exceptions to c:

When reporteddue to:

nature of injury codes
medical and surgical care
other external causes

When a nature of injury code other than T179 is reported as thefirst condition on the lowest used line in Part I.

Place I (a) Aspiration of vomitus T179 W78

0 (b) Fx hip S720

II Fall at home &W19

Do not ampersand the E-code for aspiration since both Exception 1 and 2 apply.

More than one external cause reported
In determining the most specific external cause code, considerall of the information reported on the record. If two or more external causes are reported and the nature of injuries and/or the order in which the conditions are reported indicates that one of the external causes led to the condition that terminated in death, precede the code for this external cause by an ampersand. If no determination can be made, precede the code for the first mentioned external cause with an ampersand.

Place I (a) Aspiration of vomitus T179 W78

9 (b) Internal chest injury S279

(c) Fall down stairs &W10

The order in which the conditions are reported indicates that the fall down stairs led to aspiration; therefore, the ampersand precedes the code for this external cause.

Place I (a) Gunshot wound of head S019 &X95

9 (b) Stab wound of chest S219 X99

MOD II

H

Homicide

The order in which the external causes are reported does not indicate which event occurred first; therefore, precede the code for the gunshot wound with an ampersand since it is the first external cause reported.

Place I (a) Head trauma S099

9 II Alcohol intoxication, auto accident T519 X45 &V499

Precede the code for the auto accident with an ampersand. Alcohol intoxication did not cause the head trauma.

9 (b) and temazepam) intoxication

MOD II Obesity and obstructive sleep apnea E669 G473 J969 T402 T424

A

Accident Positional respiratory compromise after

self-administering morphine and temazepam

Code I(a) as indexed, preceding the W84 with an ampersand since it is the first mentioned e-code. Assign the N and E-codes for the named drug poisoning on line I(a). In Part II, code the diseases as indexed and assign the nature of injury codes for the drugs repeated in the How Injury Occurred block.

When alcohol intoxication (or any term meaning intoxication) is reported with another external cause other than aspiration, precede the code for the first mentioned external cause with an ampersand.

When alcohol intoxication is reported with drugs, refer to Section V, Part Q, 4, Poisoning by alcohol and drugs.

When alcohol intoxication is reported with exposure or hypothermia, refer to Section V, Part L, 2, Exposure, cold exposure and hypothermia.

Place I (a) Head trauma S099

9 (b) Auto Accident &V499

(c) Alcohol intoxication T519 X45

Precede the code for the auto accident with an ampersand since it is the first external cause reported.

Place I (a) Drowning T751 &W74

9 (b) Alcohol intoxication T519 X45

Precede the code for the drowning with an ampersand since it is the first external cause reported. Code Part II as indexed.

Place I (a) Alcohol intoxication and hip fx T519 &X45 S720

9 II Fall while intoxicated W19 T519

Precede the code for the alcohol intoxication with an ampersand since it is the first external cause reported.

Place I (a) Positional asphyxia in the setting of acute ethanol T71 &W84

9 (b)intoxication T510 X45

Precede the code for the positional asphyxia with an ampersand since it is the first external cause reported.

D. Certifications with mention of nature of injury and without mention of external cause

All certifications that have an entry classifiable to Chapter XIX must have an external cause code. When only one type of injury is reported without indication of the external cause and the External Cause Index provides a code for this type of injury, code accordingly. If the External Cause Index does not provide a code for the type of injury, code to Accident, unspecified (X599). When no external cause is reported and the external cause code must be assumed, code the external cause code as the last entry in Part II.

Place I (a) Crushed chest S280

9 II &X599

Code Crushed (accidentally), X599 as indexed.

Place I (a) Fracture of hip and arm S720 T10

9 II &X590

Code Fracture (circumstances unknown or unspecified), X590 as indexed.

Place I (a) Penetrating wound of abdomen S318 S219

9 (b) and chest

II &X599

Code Wound (accidental) NEC, X599 as indexed.

If different types of injuries are reported without indication of the external cause, use the injury reported in the lowest due to position to assign the appropriate external cause code for this injury. If more than one injury is reported on the lowest line, assign the appropriate external cause code for the first mentioned injury.

Place I (a) Brain injury S069

9 (b) Fracture of skull S029

II &X590

Code Fracture (circumstances unknown or unspecified), X590.

Place I (a) Fracture of hip S720

Place I (a) Fracture of skull with generalized trauma S029 T07

9 II &X590

Code the generalized trauma as indexed. Do not relate to the site of the injury reported on the same line with it. Since there is no external cause reported, code Fracture (circumstances unknown or unspecified) as indexed in Part II.

Place I (a) Skull fracture S029

9 (b) Wound T141

II &X599

Code I(b) to Wound as indexed. Do not relate to the site of the fracture reported on the upper line. Since there is no external cause reported, code Wound (accidental) NEC, X599 as indexed in Part II.

E. Conditions qualified as traumatic

Some conditions are indexed directly to a nontraumaticcategory but the Classification also provides a traumatic code. Consider these conditions to be traumatic and code as traumatic:
When they are qualified as “traumatic”
Or they are reported on the certificate with:

Injury or trauma (any specified type or site)

F. Assumption of nature of injury code

When an external cause is reported on a certificate without a nature of injury code, assign both a nature of injury and an external cause code. Assume the nature of injury to be Injury NOS, T149 and place it preceding the external cause code.

Place I (a) Respiratory failure J969

9 (b) Fire T149 &X09

I(b) is an external cause code only. Since there is not a nature of injury reported on the certificate, code nature of injury T149 preceding the external code for fire.

Place I (a) Subarachnoid hemorrhage I609

9 (b) Stroke I64

(c) Fall T149 &W19

Do not code the hemorrhage on I(a) as traumatic since it is reported due to a nontraumatic condition. I(c) is an external cause code only and there is not a nature of injury reported on the certificate. Code nature of injury T149 preceding the external code for fall.

Place I (a) Struck by falling tree &W20

9 II Head wound S019

I(a) is an external cause code only. Since there is a nature of injury on the certificate, do not code T149 preceding the external code.

Place I (a) Struck by falling tree T149 &W20

9 II Respiratory failure J969

I(a) is an external cause code only. Since there is not a nature of injury on the certificate, code T149 preceding the external code.

Exceptions:

When conditions classified to categories A000-R99 are reported due to “second handsmoke”, code the “second hand smoke” to X49.

I (a) Pulmonary emphysema J439

I (a) Lung cancer C349

(b) Second hand smoke X49

I (a) Cardiac arrest I469

Anthrax is reported with accident, suicide, homicide or undetermined

When anthrax (A220-A229) is reported with accident, suicide or homicide anywhere on the record (including in the check box) or undetermined in the check box only, code the anthrax as indexed and code the external cause code as:

Accident specified (X58)
Suicide specified (X83)
Homicide specified (Y08)
Undetermined specified (Y33)

Anthrax designated as an act of terrorism is classified to U016.

MOD I (a) Inhalation anthrax A221

H II Y08

Homicide

Code I(a) as indexed under Anthrax, inhalation. Code an E-code only in Part II for homicide based upon the check box entry. Also enter a H for Homicide in the Manner of Death item.

I (a) Anthrax A229

(b) Homicide Y08

Code I(a) as indexed. Code an E-code only on I(b); do not assume an injury code.

J. Transportation accidents (V01-V99)

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, Chapter 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 are given below

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

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

(3) Heavy transport vehicle includes armored car, dump truck, fire truck, panel truck, semi, tow truck, tractor trailer, 18-wheeler

(4) A special all-terrain vehicle (ATV) or motor vehicle designed primarily for off-road use includes dirt bike, dune buggy, four-wheeler, go cart, golf cart, race car, snowmobile, three-wheeler

(5) Motor vehicle includes passenger vehicle (private), street sweeper

1. Use of the Index and Tabular List

The Classification 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 transport 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.

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.

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.

2. 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 traffic accident when the event is classifiable to categories V02-V04, V10-V82 and V87.
A nontraffic accident when the event is classifiable to categories V83-V86. These vehicles are designed primarily for off-road use.
Consider category V05 to be unspecified whether traffic or nontraffic if no place is indicated or if the place is railroad (tracks).
Consider category V05 to be traffic if place is railway crossing.
Consider accidents involving occupants of motor vehicles as traffic when the place is indicated or if the place is railroad (tracks).

Refer to Table of land transport accidents. Victim and mode of transport, pedestrian, in collision (with) car. Refer to Volume 1 for fourth character.

In classifying motor vehicle traffic accidents, a victim of less than 14 years of age is assumed to be a passenger provided there is evidence the decedent was an occupant of the motor vehicle. A statement such as “thrown from car,” “fall from,” “struck head on dashboard,” “drowning,” or “carbon monoxide poisoning” is sufficient.

versus (vs) etc.)

any vehicle (car, truck, versus (vs) pedestrian

etc.) versus (vs)

classify the victim as a pedestrian (V0l-V09).

4. Coding categories V01-V89

When drowning occursas a result of a motor vehicle accident NOS, code as noncollision transport accident. The assumption is the motor vehicle ran off the highway into a body of water.

O. Guides for differentiating between effects of external causes classifiable to Chapters I – XVIII and Chapter XIX

Categories in Chapters I-XVIII and XIX are mutually exclusive. Where provision has been made for coding effects of an external cause to Chapters I-XVIII, do not use a nature of injury code.

The effects of external causes classifiable to Chapters I-XVIII are primarily those associated with drugs, medicaments and biological substances, surgical procedures, and other medical procedures. Refer to Section V, Part R, Complications of medical and surgical care (Y40-Y84).

A limited number of conditions that can result from other external causes, e.g., certain localized effects of fumes, vapors and nonmedicinal chemical substances and respiratory conditions from aspiration of foreign substances are also classified to Chapters I-XVIII. It is intended that Chapters I-XVIII be used to identify the localized effects and the substance be identified by the external cause code in Chapter XX.

To determine if the conditions reported due to external causes, other than drugs, medicaments, and biological substances, surgical procedures, and other medical procedures, are classified to localized effects in Chapters I-XVIII or to the nature of injury in Chapter XIX – look up the stated condition in the Index and scan the listing under this condition for qualifying terms that relate to the reported external cause. For example, to determine whether pneumonia due to aspiration of vomitus should be coded to Chapter X or to Chapter XIX, look up “Pneumonia, aspiration, due to, food (regurgitated), milk, vomit.” This determination cannot be made by looking up “Aspiration.” Where there is provision in the Index for coding a condition due to an external cause to Chapter I-XVIII, take the external cause into account if it modifies the coding.

I (a) Pneumonia &J690

(b) Aspiration of vomitus W78

Code Pneumonia, aspiration, due to vomit. Code “aspiration of vomitus” as an external cause code only.

I (a) Pneumonia &J690

(b) Aspiration W80

(c) Cancer of lung C349

Code Pneumonia, aspiration. Code I(b) “aspiration” as an external cause code only.

II House fire

Code Pneumonia, in (due to), fumes and vapors (J680). Code I(b) external cause code only.

I (a) Acute pulmonary edema &J681

(b) Inhaled gasoline fumes X46

Code Edema, pulmonary, acute, due to, chemicals fumes or vapors (J681). Code I(b) external cause code only.

Place I (a) Pneumonia J189

9 (b) Cardiac arrest I469

(c) Aspiration of vomitus T179 &W78

Code each entity as indexed. Do not code the pneumonia on I(a) due to aspiration of vomitus since it is reported due to another condition.

P. Threats to breathing

Certain effects of external causes can be classified to more than one nature of injury code depending on the type of external cause. Some of these effects are “anoxia,” “asphyxia,” “aspiration,” “choking,” “compression of neck,” “obstruction of a site,” “strangulation,” “stricture of neck,” and “suffocation.”

The most frequently reported external causes which result in these effects are “aspiration, ingestion, and inhalation of objects and substances,” “drowning,” “fires,” “fumes, gases and vapors,” “hanging,” “mechanical strangulation and suffocation,” and “submersion.”

The following pages contain tables that are used as guides in coding these types of external causes and effects.

In general, if the specific external cause is not in Tables 1-5, it will most likely be in Table 6, which contains the most frequently reported external causes which result in asphyxia, suffocation, etc. If not in any of the tables, code the effect as indexed.

Q. Poisoning

When poisoning (any) is reported, code nature of injury code and external cause code for the substance.

When poisoning by fumes, gas, liquids, or solids is reported, refer to Index under “Poisoning (acute)” to determine the nature of injury code for the substance.

To determine the external cause code when a poisonous substance is ingested, inhaled, injected, or taken, refer to the description of such circumstances (acts) for example, Ingestion, Inhalation, or Took.

When a condition is reported due to poisoning and the Index provides a code for the condition qualified as “toxic,” use this code. If the Index does not provide a code for the condition qualified as “toxic,” code the condition as indexed.

II Status post mitral and aortic valve repair

Code I(a) valvular heart disease of unspecified valve to disease, mitral and aortic valves since the surgery is of specified valves. Do not enter a code for the surgery since there is no reported complication.

(3) When a condition of a site is reported with surgery for the same condition of unspecified or a less defined part of the site, code the condition to the most defined site.

I (a) Cancer of head of pancreas C250

II Pancreatectomy for cancer C250

Code I(a), cancer head of pancreas, C250. Code Part II as cancer of head of pancreas since elsewhere a more defined site was reported of the condition for which surgery was performed. Do not enter a code for the surgery since there is no reported complication.

(4) Do not apply these instructions when more than one condition or a condition of multiple specified sites which could have necessitated the surgery is reported.

I (a) Cardiac arrest I469

(b) Respiratory arrest R092

(c) Carcinoma of lung, liver, brain C349 C787 C793

II Findings of operation: Carcinoma C80

Code I(a), I(b) and I(c) as indexed and according to neoplasm instructions. Code Part II, carcinoma, C80. Do not code the carcinoma to a more defined site since multiple specified sites are reported for which the surgery could have been performed. Do not enter a code for the surgery since there is no reported complication.

g. Complications of amputation and amputation stump

When a complication (stated or implied) occurs as a result of an amputation, code the complication to Chapters I-XIX. When the complication is classifiable to Chapters I-XVIII and the condition that necessitated the amputation is not reported, precede the code for the complication with an ampersand.

I (a) Renal failure &N990

(b) Below knee amputation of leg Y835

Code I(a), renal failure, N990 as the complication of surgery. Code I(b), below knee amputation of leg, Y835. Precede the N990 with an ampersand since it is classified to Chapter XIV and the condition that necessitated the amputation is not reported.

When there is a complication of an amputation stump, code the complication to T873-T876 or to the appropriate code in Chapters I-XVIII. (Do not use T873-T876 for “stump” of internal organs).

I (a) Infected amputation stump T874 &Y835

(b) Osteosarcoma of leg &C402

Code I(a), infected amputation stump T874 Y835. Precede the E-code, Y835, by an ampersand. Code I(b), osteosarcoma of leg, C402. Precede C402 by an ampersand to indicate the condition that necessitated the amputation.

3. Complications of medical procedures other than surgical (Y84)

Medical procedures are any type of nonsurgical procedures used in the treatment of diseases or injuries. Although almost any condition reported due to medical procedures is regarded as a complication, there are a few diseases that are not considered complications. Do not code the conditions listed under 2. a. (1) (a) and (b) in Section V, Part R as complications of medical procedures. The medical procedure (Y84) is not coded when there is no evidence of a complication. If the reason for the medical procedure is not reported, do not assume a disease condition.

Interpret “due to medical procedures” as a condition(s) on an upper line with a medical procedure as the first condition on the next lower line.

When a condition is reported due to a named medical procedure other than a surgical operation or is modified by a named procedure and can be considered as a complication(s) or adverse effect, code as follows:

STEP 1: Determine if the complication is in the Index qualified by the specific procedure reported.

I (a) Kidney blockage &N990

(b) Postcystoscopic procedure Y848

Code I(a) as indexed using Step 1

Block

– kidney

– – postcystoscopic or postprocedural N99.0.

Code I(b) Y848 as indexed under Complication, procedures other than surgical operation, specified NEC. Precede N990 with an ampersand.

STEP 2: If the Index does not qualify the complication with the specified procedure, determine if the procedure is indexed under Complications (from) (of).

I (a) Urinary tract infection T835

(b) Post-indwelling urinary catheter &Y846

Code I(a) using Step 2

Complications (from) (of)

– catheter (device)

– – urinary (indwelling)

– – – infection or inflammation T83.5

Select infection or inflammation since urinary tract infection is an infectious condition.

Code I(b) Y846 as indexed under Complication, catheter, catheterization (urinary). Precede the E-code with an ampersand.

I (a) Pulmonary embolism T838

(b) Catheter &Y846

Code I(a) using Step 2

Complications (from) (of)

– catheter (device)

– – specified NEC T83.8

Select specified since pulmonary embolism is a specified complication.

Code I(b) Y846 as indexed under Complication, catheter, catheterization (urinary). Precede the E-code with an ampersand.

When the Index does not provide for the term as specified in STEP 1 and STEP 2, code the complication as if procedure NOS was reported instead of the named medical procedure as defined in the following instructions:

NOTE: Before continuing to STEP 3, it is important to determine the nature of the named procedure.

When a condition that is

(1) reported due to a named procedure cannot be assigned a code using STEP 1 or STEP 2 or

(2) reported due to a procedure other than surgical operation NOS or therapy NOS, and can be considered as a complication(s) or adverse effect, code as follows:

STEP 3: Determine if the complication is in the Index, qualified:

(a) as reported

(b) with any term meaning “due to” procedure or medical care (see Section II, Part C, 2, a, “Due to” written in or implied)

(c) as postprocedural

I (a) Renal failure &N990

(b) Paracentesis Y844

Code I(a) as indexed using Step 3 (c)

Failure

– renal
