ICD-10 Code F13.239 – Sedative, hypnotic or anxiolytic dependence with withdrawal, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.239 – Sedative, hypnotic or anxiolytic dependence with withdrawal, unspecified
What it is
This code identifies dependence on a sedative, hypnotic, or anxiolytic drug with withdrawal symptoms, when the specific drug is not further specified. It reflects both ongoing dependence and a withdrawal state after reduction, interruption, or cessation.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented withdrawal findings may include anxiety, insomnia, tremor, agitation, or autonomic symptoms after stopping the medication.
When to use this code
Use this code when the provider documents sedative, hypnotic, or anxiolytic dependence and also documents withdrawal, but does not name the exact substance. It also fits when the record states “unspecified” or the drug class is known but the individual agent is not. Check documentation for whether intoxication, abuse, or another substance use disorder code is more accurate.
Do not use for
Do not use this code for simple use, abuse, or intoxication without dependence and withdrawal. If the substance or withdrawal status is unclear, check documentation before assigning F13.239.
Coding tip
Code the dependence and withdrawal only when both are explicitly documented; if the drug is named, select a more specific F13.23- code when available.
