ICD-10 Code F19.231 – Other Psychoactive Substance Dependence with Withdrawal Delirium (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F19.231 – Other psychoactive substance dependence with withdrawal delirium
What it is
F19.231 identifies dependence on another psychoactive substance, with delirium caused by withdrawal. Use it when the record shows both substance dependence and a withdrawal-related delirium state.
Clinical signs
Clinical features vary; refer to documentation. Delirium may include confusion, reduced attention, disorientation, and fluctuating awareness, with signs of substance withdrawal noted by the clinician.
When to use this code
Use this code when the provider documents dependence on an unspecified or other psychoactive substance and clearly links the delirium to withdrawal. It fits inpatient or emergency records describing withdrawal delirium in a dependent patient.
If the substance is named, verify whether a more specific ICD-10-CM code applies. Check documentation for the exact substance, dependence status, and whether delirium is explicitly attributed to withdrawal.
Do not use for
Do not use this code for simple intoxication, uncomplicated withdrawal, or substance use without dependence. Also avoid it when delirium has another documented cause. Check documentation.
Coding tip
Confirm the substance category and the provider’s wording for dependence plus withdrawal delirium before assigning F19.231.
