ICD-10 Code F19.922 – Other psychoactive substance use, unspecified with intoxication with perceptual disturbance (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.922 – Other psychoactive substance use, unspecified with intoxication with perceptual disturbance
What it is
This code identifies intoxication from an unspecified psychoactive substance with perceptual disturbance. Use it when the substance is known to be psychoactive but not named, and the chart documents altered perception during intoxication.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see hallucinations, misperceptions, or other perceptual changes occurring during acute intoxication, along with substance use evidence.
When to use this code
Use F19.922 when the record clearly states intoxication from an unspecified psychoactive substance and notes perceptual disturbance. This fits emergency, inpatient, or behavioral health documentation where the exact substance is not identified. Check documentation if the record only says intoxication without perceptual changes.
Do not use for
Do not use this code for simple substance use without intoxication, or when the psychotic symptoms are better explained by a primary mental disorder. If the substance is specified, choose the more specific code.
Coding tip
Code the substance category and the documented intoxication feature together; if either element is missing, check documentation.
