ICD-10 Code F13.131 – Sedative, hypnotic or anxiolytic abuse with withdrawal delirium (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.131 – Sedative, hypnotic or anxiolytic abuse with withdrawal delirium
What it is
This code identifies abuse of sedative, hypnotic, or anxiolytic drugs with delirium caused by withdrawal. Use it when the record shows both substance abuse and a withdrawal-related delirious state.
Clinical signs
Clinical features vary; refer to documentation. Delirium usually includes disturbed attention, confusion, altered awareness, and fluctuating cognition, with a withdrawal context from the specified drug class.
When to use this code
Use this code when the provider documents sedative, hypnotic, or anxiolytic abuse and explicitly links the current delirium to withdrawal. It may appear in detoxification, emergency, or inpatient notes. Confirm the substance class and the withdrawal delirium diagnosis in the record.
Do not use for
Do not use this code for simple intoxication, dependence without abuse, or withdrawal without delirium. If the documentation does not specify the substance pattern or delirium, check documentation.
Coding tip
Code the documented substance use condition exactly as stated, and verify that withdrawal delirium is clearly attributed to the sedative, hypnotic, or anxiolytic class.
