Code Description

ICD-10 F16.251 is a billable code used to indicate a diagnosis of hallucinogen dependence with hallucinogen-induced psychotic disorder with hallucinations.

Key Diagnostic Point:

Hallucinogen dependence with hallucinogen-induced psychotic disorder with hallucinations is characterized by a compulsive pattern of hallucinogen use leading to significant impairment or distress. Individuals with this condition experience persistent hallucinations, delusions, and other psychotic symptoms directly attributable to the use of hallucinogenic substances such as LSD, psilocybin, or mescaline. The dependence manifests as a strong desire to consume hallucinogens, often resulting in tolerance and withdrawal symptoms when not using the substance. The psychotic disorder component indicates that the individual experiences hallucinations that can affect their perception of reality, leading to potential risks of harm to themselves or others. Treatment typically involves a combination of psychotherapy, medication management, and support groups, focusing on both the substance use disorder and the psychotic symptoms. Clinicians must carefully assess the severity of the dependence and the impact of the psychotic disorder on the patient's functioning to develop an effective treatment plan.
