Hallucinogen abuse, uncomplicated

This code signifies a pattern of problematic hallucinogen use leading to clinically significant impairment or distress, without the presence of physiological dependence or withdrawal symptoms. It indicates a non-dependent, non-severe form of hallucinogen use disorder.

Apply this code when documentation clearly indicates a patient's misuse of hallucinogens (e.g., LSD, PCP, psilocybin) without evidence of tolerance, withdrawal, or a severe substance use disorder. This is appropriate for initial evaluations or ongoing management where the patient does not meet criteria for dependence.

• Differentiate from hallucinogen dependence (F16.2-) which involves tolerance or withdrawal.
• Always review documentation for specific hallucinogen type if available (e.g., F16.12- for hallucinogen abuse with intoxication).
• Do not use if the patient is experiencing intoxication or a hallucinogen-induced mental disorder; separate codes exist for those conditions.
