Drug Use-Associated Hospital Encounters Involving Co-occurring Disorders by Month From Selected Hospitals
Drug Use Hospital Data
The National Hospital Care Survey (NHCS), conducted by the National Center for Health Statistics (NCHS), collects data on patient care in hospital-based settings to describe patterns of health care delivery and use in the United States. Settings include inpatient facilities and emergency departments (EDs).
NHCS results provided on drug use-associated hospital encounters are from UB–04 administrative claims data from August 1, 2022, through July 31, 2024, from 24 hospitals that submitted inpatient data and 24 hospitals that submitted ED data. The data used in these figures are preliminary, and the results may change with subsequent releases. The data file will be updated every 2 months. The data are not nationally representative but can provide insight on the impact of drug use on various types of hospitals throughout the country.
Results show the percentage of specific drug use-associated encounters involving co-occurring disorders for all drugs, all opioids, benzodiazepines, cannabis, and stimulants among all inpatient or ED encounters over time. A co-occurring disorders encounter is defined as a drug use-associated hospital encounter with evidence of a substance use disorder diagnosis (alcohol, opioid, cannabis, sedative, cocaine, other stimulants, hallucinogen, inhalant, tobacco, and other psychoactive substance related disorders) and a diagnosis of a selected mental health issue (anxiety, trauma, obsessive compulsive, depression, and self-harm thoughts or behaviors). Data are presented for each setting (inpatient and ED) and calendar month by age and sex. These drug categories are defined by any listed International Classification of Diseases, 10th Revision, Clinical Modification (ICD–10–CM) diagnosis code as follows:
- Co-occurring Disorders—A hospital encounter involving co-occurring disorders is defined as having any listed ICD–10–CM diagnosis code for a substance use disorder and any ICD–10–CM diagnosis code for a selected mental health issue as defined here: Indicator ICD-10 Codes.
- All Drugs—A hospital encounter involving all drugs is defined as any listed ICD–10–CM diagnosis code for Indicator ICD-10 Codes.
- All Opioids—A hospital encounter involving all opioids is defined as any listed ICD–10–CM diagnosis code for Indicator ICD-10 Codes.
- Benzodiazepines—A hospital encounter involving benzodiazepines is defined as any listed ICD–10–CM diagnosis code for Indicator ICD-10 Codes.
- Cannabis—A hospital encounter involving cannabis is defined as any listed ICD–10–CM diagnosis code for Indicator ICD-10 Codes.
- Stimulants—A hospital encounter involving all stimulants is defined as any listed ICD–10–CM diagnosis code for Indicator ICD-10 Codes.

Data Source
The data presented are from the 2022, 2023, and 2024 NHCS. The data in these figures are preliminary and are not nationally representative. All estimates shown meet the NCHS Data Presentation Standards for Proportions.
NHCS’ goal is to produce national estimates on hospital care and use. The survey collects electronic data from Uniform Bill (UB–04) administrative claims or electronic health records for all encounters in a calendar year from a nationally representative sample of 608 hospitals. Information collected includes diagnoses, procedures, demographics, discharge status, and patient identifiers such as name and date of birth. Eligible hospitals from the 50 states and District of Columbia include noninstitutional and nonfederal hospitals with six or more staffed inpatient beds. Hospitals are currently being received into the survey. The survey is designed to produce objective and timely data to assess the health and well-being of the population and the performance and functioning of the health care system.
