ICD-10 Code F13.931 – Sedative, hypnotic or anxiolytic use, unspecified with withdrawal delirium (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F13.931 – Sedative, hypnotic or anxiolytic use, unspecified with withdrawal delirium
What it is
This code identifies withdrawal delirium caused by sedative, hypnotic, or anxiolytic use when the substance is unspecified. It reflects a severe withdrawal state with confusion and impaired awareness.
Clinical signs
Typical findings include acute confusion, disorientation, agitation, and fluctuating attention or consciousness. Clinical features vary; refer to documentation for evidence of delirium linked to withdrawal.
When to use this code
Use this code when the record documents delirium due to withdrawal from a sedative, hypnotic, or anxiolytic, but the specific drug is not named. You may also use it when the clinician clearly links the delirium to withdrawal and no more specific code is available. Check documentation for the substance type and withdrawal diagnosis.
Do not use for
Do not use this code for uncomplicated withdrawal without delirium or for intoxication. Do not use it when the specific substance is documented and a more precise code applies.
Coding tip
Confirm both withdrawal and delirium are documented, and code the substance as unspecified only when the record does not identify it.
