ICD-10 Code F13.99 – Sedative, hypnotic or anxiolytic use, unspecified with unspecified sedative, hypnotic or anxiolytic-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.99 – Sedative, hypnotic or anxiolytic use, unspecified with unspecified sedative, hypnotic or anxiolytic-induced disorder
What it is
This code identifies a sedative, hypnotic, or anxiolytic use disorder when the specific substance is not named and the related substance-induced disorder is also not further specified. Use it when documentation confirms both use and an associated disorder, but details are limited.
Clinical signs
Clinical features vary; refer to documentation. Records may describe misuse, dependence-related behavior, intoxication, withdrawal, or another substance-induced mental or physical change without naming the exact sedative or the exact disorder.
When to use this code
Use this code when the provider documents unspecified sedative, hypnotic, or anxiolytic use together with an unspecified induced disorder. It fits cases where the chart confirms the drug class and a substance-related disorder, but the exact agent or syndrome is not documented. If the record names a specific substance or disorder, code that more specific option instead.
Do not use for
Do not use this code for uncomplicated use without a substance-induced disorder, or when the substance class is not sedative, hypnotic, or anxiolytic. Check documentation if the induced condition is clearly identified elsewhere.
Coding tip
Verify both elements in the note: unspecified sedative, hypnotic, or anxiolytic use and an unspecified induced disorder.
