ICD-10 Code F10.931 – Alcohol use, unspecified with withdrawal delirium (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F10.931 – Alcohol use, unspecified with withdrawal delirium
What it is
This code identifies alcohol use, unspecified, with withdrawal delirium, also called delirium tremens. Use it when the patient has delirium caused by stopping or reducing alcohol after regular use.
Clinical signs
Typical findings include confusion, disorientation, agitation, hallucinations, and fluctuating attention during alcohol withdrawal. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly links delirium to alcohol withdrawal and the alcohol use is documented as unspecified. It is appropriate for inpatient or emergency visits when the provider diagnoses withdrawal delirium. Check documentation if the chart does not state alcohol-related delirium.
Do not use for
Do not use it for alcohol intoxication, uncomplicated withdrawal, or delirium from another cause. If the note identifies a different alcohol category or a separate delirium cause, code that instead.
Coding tip
Confirm that both alcohol use and withdrawal delirium are documented together before assigning F10.931.
