Hallucinogen dependence w unsp hallucinogen-induced disorder

This code signifies a patient's physiological and psychological dependence on hallucinogenic substances, accompanied by a hallucinogen-induced mental health condition that is not otherwise specified. This indicates a pattern of compulsive hallucinogen use leading to clinically significant impairment or distress, with an associated psychiatric symptomology that lacks further diagnostic clarity.

Apply this code when documentation confirms hallucinogen dependence and a co-occurring hallucinogen-induced disorder, but the specific nature of the induced disorder (e.g., psychosis, mood disorder, anxiety disorder) is not detailed. This code is appropriate when the provider has diagnosed both dependence and an unspecified hallucinogen-induced condition.

• Ensure documentation explicitly states both "hallucinogen dependence" and an "unspecified hallucinogen-induced disorder."
• Avoid using this code if a more specific hallucinogen-induced disorder (e.g., F16.250 for hallucinogen-induced psychotic disorder with delusions) is documented.
• Always sequence this code as a primary diagnosis when it is the focus of the encounter, or as a secondary diagnosis if the primary reason for the encounter is another condition.
