2008 ICD-9-CM Table of Drugs

    This table contains a classification of drugs and other chemical substances to identify poisoning states and external causes of adverse effects.

    Each of the listed substances in the data below assigned a code according to the poisoning classification (960-989). These codes are used when there is a statement of poisoning, overdose, wrong substance given or taken, or intoxication.

    The table also contains a listing of external causes of adverse effects. An adverse effect is a pathologic manifestation due to ingestion or exposure to drugs or other chemical substances (e.g., dermatitis, hypersensitivity reaction, aspirin gastritis). The adverse effect is to be identified by the appropriate code found in Section 1, Index to Diseases and Injuries. An external cause code can then be used to identify the circumstances involved. The table headings pertaining to external causes are defined below:

    • Accidental poisoning (E850-E869) accidental overdose of drug, wrong substance given or taken, drug taken inadvertently, accidents in the usage of drugs and biologicals in medical and surgical procedures, and to show external causes of poisonings classifiable to 980-989.
    • Therapeutic use (E930-E949) a correct substance properly administered in therapeutic or prophylactic dosage as the external cause of adverse effects.
    • Suicide attempt (E950-E952) instances in which self-inflicted injuries or poisonings are involved.
    • Assault (E961-E962) injury or poisoning inflicted by another person with the intent to injure or kill.
    • Undetermined (E980-E982) to be used when the intent of the poisoning or injury cannot be determined whether it was intentional or accidental.
