ICD-10 Code F12.15 – Cannabis abuse with psychotic disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F12.15 – Cannabis abuse with psychotic disorder
What it is
This code identifies cannabis abuse accompanied by a psychotic disorder. Use it when documentation links cannabis misuse with psychotic symptoms such as hallucinations or delusions.
Clinical signs
Clinical features vary; refer to documentation. Typical psychotic findings may include hallucinations, delusions, disorganized thinking, or marked behavioral disturbance occurring in the setting of cannabis abuse.
When to use this code
Use F12.15 when the provider documents cannabis abuse and a psychotic disorder caused by, or associated with, cannabis use. It fits encounters where the psychosis is the clinically relevant complication of the substance use. Check documentation if the record instead describes intoxication, dependence, or an unspecified cannabis-related disorder.
Do not use for
Do not use this code for cannabis use without abuse, or for psychotic disorders unrelated to cannabis. If the chart does not clearly connect the psychosis to cannabis abuse, check documentation.
Coding tip
Code the substance-related psychotic disorder only when the provider explicitly documents the cannabis link.
