ICD-10 Code F19.929 – Other psychoactive substance use, unspecified with intoxication, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.929 – Other psychoactive substance use, unspecified with intoxication, unspecified
What it is
This code identifies intoxication from a psychoactive substance that is not otherwise specified. Use it when the substance is known to be psychoactive, but the record does not name the exact drug or document the intoxication type.
Clinical signs
Clinical features vary; refer to documentation. Intoxication may include altered mental status, impaired coordination, abnormal behavior, or other acute effects consistent with substance use.
When to use this code
Use this code when the provider documents intoxication related to an unspecified psychoactive substance and does not identify a more specific substance or intoxication pattern. It is appropriate for acute encounters where the chart supports intoxication but remains nonspecific. Check documentation if the substance is later clarified.
Do not use for
Do not use this code when the substance is named and a more specific ICD-10-CM code is available. Avoid it for dependence, abuse, or withdrawal without intoxication.
Coding tip
Code the most specific substance and intoxication type documented; use F19.929 only when the record remains unspecified.
