ICD-10 Code F10.99 – Alcohol use, unspecified with unspecified alcohol-induced disorder (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F10.99 – Alcohol use, unspecified with unspecified alcohol-induced disorder
What it is
F10.99 identifies alcohol use disorder when the record does not specify the pattern of use and the alcohol-induced disorder is also not further defined. Use it only when documentation supports both alcohol involvement and an unspecified alcohol-related condition.
Clinical signs
Clinical features vary; refer to documentation. Records may mention alcohol-related impairment, intoxication, withdrawal, or another alcohol-induced disorder, but the exact disorder is not named.
When to use this code
Use this code when the provider documents alcohol use with an alcohol-induced disorder, but the chart does not identify the specific disorder. It may fit cases where the note says “alcohol-related disorder” or similar vague wording. Check documentation before assigning it, especially if a more specific F10 code is recorded elsewhere.
Do not use for
Do not use this code when the record specifies the exact alcohol-induced condition, such as intoxication, withdrawal, or another named disorder. Also avoid it if alcohol use is documented without any alcohol-induced disorder.
Coding tip
If the provider’s wording is nonspecific, query for clarification before defaulting to F10.99.
