Oth psychoactive substance dependence w withdrawal delirium

This code signifies a patient's physiological and psychological reliance on a psychoactive substance, excluding alcohol, opioids, cannabis, sedatives/hypnotics, cocaine, stimulants, and hallucinogens, accompanied by the acute onset of delirium during withdrawal. Delirium in this context involves a disturbance in attention, awareness, and cognition that develops over a short period.

Apply this code when documentation clearly indicates dependence on a "catch-all" psychoactive substance (e.g., inhalants, phencyclidine, or other unspecified substances) and the patient is experiencing withdrawal symptoms that include delirium. This requires a physician's diagnosis of both substance dependence and withdrawal delirium.

• Ensure the specific psychoactive substance is not one with a more specific ICD-10-CM code (e.g., F10-F16, F18).
• Documentation must explicitly state "withdrawal delirium" in addition to dependence.
• Consider sequencing this code after any acute intoxication codes if applicable, or as the primary diagnosis if it is the reason for the encounter.
