ICD-10 Code F13.939 – Sedative, hypnotic or anxiolytic use, unspecified with withdrawal, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.939 – Sedative, hypnotic or anxiolytic use, unspecified with withdrawal, unspecified
What it is
This code identifies withdrawal from sedative, hypnotic, or anxiolytic use when the specific substance and the withdrawal details are not documented. It signals a substance-related withdrawal state rather than simple use or intoxication.
Clinical signs
Withdrawal may include anxiety, tremor, insomnia, agitation, or autonomic symptoms. Clinical features vary; refer to documentation and avoid assuming a specific drug without support.
When to use this code
Use this code when the record documents withdrawal from a sedative, hypnotic, or anxiolytic drug, but the substance remains unspecified. It also fits when withdrawal is noted without enough detail to assign a more specific code. Check documentation for drug name, pattern, and severity.
Do not use for
Do not use it for uncomplicated use, intoxication, or dependence without withdrawal. If the substance or withdrawal type is specified, choose the more precise code.
Coding tip
Confirm both the substance class and the presence of withdrawal before assigning F13.939.
