ICD-10 Code F19.251 – Other psychoactive substance dependence with psychoactive substance-induced psychotic disorder with hallucinations (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.251 – Other psychoactive substance dependence with psychoactive substance-induced psychotic disorder with hallucinations
What it is
This code identifies dependence on another psychoactive substance, along with a substance-induced psychotic disorder that includes hallucinations. Use it when the psychosis is documented as caused by the substance and not by a primary mental disorder.
Clinical signs
Typical findings include hallucinations, impaired reality testing, and other psychotic symptoms that occur in the setting of substance use. Clinical features vary; refer to documentation for the specific substance, timing, and whether symptoms persist beyond intoxication or withdrawal.
When to use this code
Use this code when the record clearly links the psychotic disorder with hallucinations to dependence on a non-listed psychoactive substance. It is appropriate when the provider documents both dependence and a substance-induced psychotic disorder.
Choose this code only when the hallucinations are part of the substance-induced psychosis. If the documentation does not identify the substance or the causal relationship, check documentation before coding.
Do not use for
Do not use this code for psychosis unrelated to substance use, or for hallucinations caused by intoxication alone without a documented psychotic disorder. Do not apply it when another, more specific ICD-10-CM code is documented.
Coding tip
Confirm both dependence and the substance-induced psychotic disorder are documented, and code the most specific substance-related diagnosis available.
