ICD-10 Code F13.1 – Sedative, hypnotic or anxiolytic-related abuse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.1 – Sedative, hypnotic or anxiolytic-related abuse
What it is
Use this code for problematic use of sedative, hypnotic, or anxiolytic substances that is documented as abuse. It indicates harmful or inappropriate use, without enough detail to code dependence or an acute intoxication event.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe recurrent nonmedical use, taking more than prescribed, or continued use despite adverse effects or social problems.
When to use this code
Assign F13.1 when the record clearly states abuse of a sedative, hypnotic, or anxiolytic drug. Use it for outpatient, inpatient, or emergency documentation when the provider identifies abuse rather than dependence, intoxication, or withdrawal.
If the chart only says “misuse” or gives limited history, check documentation before coding. When multiple substances are involved, code each documented substance-related disorder separately if supported.
Do not use for
Do not use this code for dependence, intoxication, withdrawal, or poisoning. Also avoid it when the record does not specifically support abuse; check documentation.
Coding tip
Code the specific sedative, hypnotic, or anxiolytic substance whenever the record identifies it, and verify whether abuse is the only documented disorder.
