ICD-10 Code F19.120 – Other psychoactive substance abuse with intoxication, uncomplicated (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.120 – Other psychoactive substance abuse with intoxication, uncomplicated
What it is
Use this code for abuse of a psychoactive substance, other than the specifically named drug classes, when the patient is intoxicated and there are no documented complications. It indicates a substance-related behavioral or physical effect without delirium, psychosis, or other added conditions.
Clinical signs
Clinical features vary; refer to documentation. Intoxication may include altered mood, impaired judgment, unusual behavior, or reduced coordination consistent with recent substance use, but the record must support uncomplicated intoxication.
When to use this code
Assign this code when the provider documents abuse of another psychoactive substance and states intoxication is present, with no complication noted. Use it for encounters focused on the acute intoxication state, not long-term dependence or withdrawal. Check documentation if the substance is not clearly identified.
Do not use for
Do not use this code for dependence, remission, withdrawal, or intoxication with delirium, psychotic disorder, or other specified complication. Also avoid it when the substance belongs to a more specific ICD-10 category.
Coding tip
Confirm both abuse and uncomplicated intoxication are documented before assigning F19.120.
