2026 ICD-10-CM Diagnosis Code F13.959 – Sedative, hypnotic or anxiolytic use, unspecified with sedative, hypnotic or anxiolytic-induced psychotic disorder, unspecified
What it is
This code identifies psychotic disorder symptoms caused by sedative, hypnotic, or anxiolytic use when the use pattern is unspecified. It is used when the record links the substance to hallucinations, delusions, or other psychotic features.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include hallucinations, delusions, disorganized thinking, or marked behavioral changes occurring in the context of sedative, hypnotic, or anxiolytic use.
When to use this code
Use this code when the provider documents both unspecified sedative, hypnotic, or anxiolytic use and a substance-induced psychotic disorder. The record should clearly connect the psychotic episode to the substance. If the substance or the psychotic diagnosis is not documented, check documentation before coding.
Do not use for
Do not use it for psychosis unrelated to substance use, or for intoxication, withdrawal, or dependence without psychotic disorder. Check documentation if the chart only mentions anxiety, sleep problems, or medication use alone.
Coding tip
Code the substance-related psychotic disorder only when the provider explicitly links the psychosis to sedative, hypnotic, or anxiolytic use.
