ICD-10 Code F15.159 – Other stimulant abuse with stimulant-induced psychotic disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.159 – Other stimulant abuse with stimulant-induced psychotic disorder, unspecified
What it is
This code identifies stimulant abuse with a stimulant-induced psychotic disorder when the stimulant is not otherwise specified and the psychosis type is unspecified. Use it for documented stimulant-related psychotic symptoms linked to abuse.
Clinical signs
Clinical features vary; refer to documentation. Typical psychotic findings may include hallucinations, delusions, paranoia, or disorganized thinking occurring in the setting of stimulant use.
When to use this code
Use this code when the record documents abuse of another stimulant and a psychotic disorder caused by that stimulant, but the psychosis is not further specified. It also fits when the substance is identified only as an other stimulant and the provider links the psychosis to use. Check documentation if the record instead describes intoxication, dependence, or an unspecified substance-related disorder.
Do not use for
Do not use this code for stimulant use without psychosis, or when the diagnosis is dependence rather than abuse. Do not assign it if the psychosis is unrelated to stimulant use or the substance is not documented.
Coding tip
Code the stimulant-related psychotic disorder only when the provider clearly documents the causal link between stimulant abuse and psychosis.
