ICD-10 Code F13.9 – Sedative, hypnotic or anxiolytic-related use, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.9 – Sedative, hypnotic or anxiolytic-related use, unspecified
What it is
This code identifies a sedative, hypnotic, or anxiolytic-related disorder that is not further specified in the record. Use it when documentation confirms involvement of this drug class but does not describe a more precise pattern or complication.
Clinical signs
Clinical features vary; refer to documentation. Records may note misuse, dependence, intoxication, or withdrawal related to these medications, but the chart does not support a more specific diagnosis.
When to use this code
Use F13.9 when the provider documents a sedative, hypnotic, or anxiolytic-related condition and leaves it unspecified. It is appropriate when the note lacks details needed for a more exact F13 code. Check documentation if the record suggests intoxication, dependence, or withdrawal.
Do not use for
Do not use this code when the record clearly identifies intoxication, dependence, withdrawal, or another specific sedative-related disorder. Also avoid it if the medication class is mentioned only as current therapy without a related diagnosis.
Coding tip
Query for the exact disorder and severity when the note only says “sedative-related” or “anxiolytic use.”
