ICD-10 Code F13.93 – Sedative, hypnotic or anxiolytic use, unspecified with withdrawal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.93 – Sedative, hypnotic or anxiolytic use, unspecified with withdrawal
What it is
Use this code for withdrawal symptoms after stopping or reducing a sedative, hypnotic, or anxiolytic when the specific drug is not documented. It indicates the patient is in withdrawal, but the substance class is not further specified.
Clinical signs
Common findings include anxiety, tremor, insomnia, agitation, and autonomic symptoms after recent discontinuation. Clinical features vary; refer to documentation.
When to use this code
Assign this code when the record clearly states sedative, hypnotic, or anxiolytic withdrawal and does not identify a more specific substance. Use it for encounters documenting dependence-related withdrawal symptoms, detoxification, or adverse effects from stopping the drug. Check documentation if the substance is named.
Do not use for
Do not use this code for intoxication, abuse without withdrawal, or dependence without withdrawal. Also avoid it when a specific sedative or anxiolytic is documented and a more precise code is available.
Coding tip
Look for the exact phrase “with withdrawal” and confirm the substance is unspecified before selecting F13.93.
