Code Description

ICD-10 F13.231 is a billable code used to indicate a diagnosis of sedative, hypnotic or anxiolytic dependence with withdrawal delirium.

Key Diagnostic Point:

F13.231 refers to a condition characterized by a dependence on sedative, hypnotic, or anxiolytic substances, accompanied by withdrawal delirium. This condition arises when an individual has developed a tolerance to these substances, leading to increased consumption to achieve the desired effects. Upon cessation or reduction of intake, withdrawal symptoms manifest, which can include severe agitation, confusion, hallucinations, and delirium. The clinical presentation may vary, but the hallmark of withdrawal delirium is a marked disturbance in consciousness and cognition, often requiring immediate medical intervention. Treatment typically involves supportive care, pharmacotherapy to manage symptoms, and rehabilitation programs aimed at addressing the underlying substance use disorder. Accurate diagnosis and coding are crucial for effective treatment planning and insurance reimbursement.
