ICD-10 Code F13.159 – Sedative, hypnotic or anxiolytic abuse with sedative, hypnotic or anxiolytic-induced psychotic disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.159 – Sedative, hypnotic or anxiolytic abuse with sedative, hypnotic or anxiolytic-induced psychotic disorder, unspecified
What it is
This code identifies abusive use of sedative, hypnotic, or anxiolytic drugs with a resulting psychotic disorder, but the psychosis type is not specified. Use it when the record links the substance misuse to the psychotic episode.
Clinical signs
Clinical features vary; refer to documentation. Typical psychotic findings may include hallucinations, delusions, disorganized thinking, or marked behavioral disturbance, with evidence of recent sedative, hypnotic, or anxiolytic abuse.
When to use this code
Use this code when the provider documents abuse of a sedative, hypnotic, or anxiolytic and also documents a substance-induced psychotic disorder without further specification. It fits cases where the psychosis is attributed to the drug use, but the exact psychotic subtype is not stated. Confirm the relationship in the note before coding.
Do not use for
Do not use this code for simple drug intoxication, dependence, or withdrawal without psychosis. If the psychotic disorder is due to another substance or is more specifically identified, choose the matching code.
Coding tip
Check that both abuse and the substance-induced psychotic disorder are documented, because one diagnosis alone does not support F13.159.
