ICD-10 Code F13.2 – Sedative, hypnotic or anxiolytic-related dependence (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.2 – Sedative, hypnotic or anxiolytic-related dependence
What it is
This code identifies dependence on sedative, hypnotic, or anxiolytic substances. Use it when the record shows a pattern of ongoing use with impaired control, withdrawal, or continued use despite harm.
Clinical signs
Clinical features may include tolerance, withdrawal symptoms, craving, and difficulty cutting down. Clinical features vary; refer to documentation.
When to use this code
Assign F13.2 when the provider documents dependence on a sedative, hypnotic, or anxiolytic medication or substance. Use it for cases described as addiction, dependence, or chronic use with withdrawal or loss of control. Do not infer dependence from use alone.
Do not use for
Do not use this code for simple therapeutic use, acute intoxication, or harmful use without dependence. Check documentation if the note only states misuse, overdose, or adverse effect.
Coding tip
Code the specific substance-related disorder first when documented, and verify dependence is explicitly stated or clearly supported in the record.
