ICD-10 Code F15.259 – Other stimulant dependence with stimulant-induced psychotic disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F15.259 – Other stimulant dependence with stimulant-induced psychotic disorder, unspecified
What it is
This code identifies dependence on other stimulants, along with a stimulant-induced psychotic disorder when the psychosis type is not further specified. Use it when the record links stimulant use to psychotic symptoms and the substance is not cocaine or another more specific stimulant.
Clinical signs
Clinical features may include hallucinations, delusions, paranoia, or disorganized thinking that occur in the setting of stimulant use. Clinical features vary; refer to documentation for the substance involved and whether the psychosis is judged to be substance induced.
When to use this code
Use this code when documentation states both stimulant dependence and a stimulant-induced psychotic disorder, and the stimulant is classified as “other” rather than a specifically named drug. It also fits when the psychosis is documented as unspecified. If the record does not clearly connect the psychosis to stimulant use, check documentation.
Do not use for
Do not use it for stimulant abuse without dependence, or for psychotic disorders unrelated to substance use. Also avoid it when documentation names a different substance category or provides a more specific stimulant diagnosis.
Coding tip
Code the dependence and substance-induced psychosis together only when the provider clearly documents that relationship.
