ICD-10 Code F13.13 – Sedative, hypnotic or anxiolytic abuse with withdrawal (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.13 – Sedative, hypnotic or anxiolytic abuse with withdrawal
What it is
Use this code for documented abuse of sedative, hypnotic, or anxiolytic drugs when withdrawal symptoms are present. It indicates harmful use with a withdrawal state, not simple dependence or intoxication.
Clinical signs
Clinical features vary; refer to documentation. Withdrawal may include anxiety, tremor, insomnia, agitation, or autonomic symptoms after reduction or stopping of the substance.
When to use this code
Assign F13.13 when the record clearly states sedative, hypnotic, or anxiolytic abuse and also documents withdrawal. Use it for encounters where the provider links current symptoms to withdrawal from these agents.
Code based on the provider’s diagnosis, assessment, or discharge summary. If the chart only says use, misuse, dependence, or intoxication without withdrawal, check documentation before coding.
Do not use for
Do not use this code for uncomplicated abuse, dependence, intoxication, or poisoning. Also avoid it when withdrawal is not documented or the substance class is different.
Coding tip
Confirm both elements are present in the note: abuse and withdrawal.
