ICD-10 Code F10.9 – Alcohol use, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F10.9 – Alcohol use, unspecified
What it is
F10.9 identifies alcohol use without a more specific diagnosis or detail. Use it when documentation confirms alcohol involvement but does not specify abuse, dependence, intoxication, or another related disorder.
Clinical signs
Clinical features vary; refer to documentation. You may see alcohol use noted in the chart without qualifying symptoms, severity, or complication details.
When to use this code
Use this code when the provider documents alcohol use and no further classification is stated. It is appropriate when the record lacks enough detail to assign a more specific F10 code. Check documentation if the note suggests intoxication, withdrawal, or dependence.
Do not use for
Do not use F10.9 when the record clearly supports intoxication, dependence, withdrawal, or alcohol-induced conditions. If the documentation is more specific, code the exact disorder instead.
Coding tip
Confirm the provider’s wording and code the most specific alcohol-related diagnosis supported by the record.
