ICD-10 Coding — Adverse Effects in ICD-10-CM​

Poisoning

When coding a poisoning or reaction to the improper use of a medication (overdose, wrong substance given or taken in error, wrong route of administration), first assign the appropriate code from categories T36-T50. The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined. If the intent of the poisoning is unknown or unspecified, code the intent as accidental intent. The undetermined intent is only for use if the documentation in the record specifies that the intent cannot be determined.

Use additional code(s) for all manifestations of poisonings.
If there is also a diagnosis of abuse or dependence of the substance, the abuse or dependence is assigned as an additional code.

Examples of poisoning include:

• Errors made in drug prescription or in the administration of the drug by a health care professional.
• If an overdose of a drug was intentionally taken or administered and resulted in drug toxicity, it would be coded as a poisoning.
• If a non-prescribed drug or medicinal agent was taken in combination with a correctly prescribed & properly administered drug, any drug toxicity or other reaction resulting from the interaction of the two drugs would be a poisoning.
• When a reaction results from the interaction of a drug(s) and alcohol, this would be classified as poisoning.
