ICD-10 Code F19.1 – Other psychoactive substance abuse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.1 – Other psychoactive substance abuse
What it is
F19.1 identifies harmful use of a psychoactive substance that is not one of the more specific drug categories. Use this code when the record clearly documents abuse rather than dependence or uncomplicated use.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may note recurrent misuse, impaired control, social or occupational problems, or substance-related consequences without clear dependence criteria.
When to use this code
Use F19.1 when the clinician documents abuse of an other psychoactive substance and does not name a more specific ICD-10 category. It may apply to mixed or less common substances when the record supports abuse. If the note only says use, intoxication, or dependence, check documentation before coding.
Do not use for
Do not use this code for dependence, uncomplicated use, or acute intoxication alone. If the substance is identified by a more specific code, choose that code instead.
Coding tip
Code from the provider’s exact wording and confirm the substance category whenever possible.
