ICD-10 Code F10.27 – Alcohol dependence with alcohol-induced persisting dementia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F10.27 – Alcohol dependence with alcohol-induced persisting dementia
What it is
This code identifies alcohol dependence together with a persisting dementia caused by alcohol use. It applies when cognitive decline continues beyond acute intoxication or withdrawal and is documented as alcohol-induced.
Clinical signs
Typical findings include ongoing memory loss, impaired judgment, disorientation, and reduced ability to manage daily activities. Clinical features vary; refer to documentation for evidence that the dementia is attributed to alcohol.
When to use this code
Use F10.27 when the record clearly states alcohol dependence and a persisting dementia linked to alcohol. You may also use it when the clinician documents alcohol-induced major cognitive impairment that is not limited to a transient state. Ensure the note supports both conditions.
Do not use for
Do not use this code for uncomplicated alcohol dependence without dementia, or for acute intoxication, withdrawal, or delirium alone. Check documentation if the cognitive disorder is not specifically linked to alcohol.
Coding tip
Assign the code only when the provider documents both alcohol dependence and a persisting alcohol-induced dementia.
