Hallucinogen dependence w hallucinogen-induced mood disorder

This code signifies a severe pattern of hallucinogen use characterized by tolerance, withdrawal, and compulsive drug-seeking behavior, coupled with a co-occurring mood disturbance directly attributable to the hallucinogen use. The mood disorder can manifest as depression, mania, or mixed affective states. The dependence indicates a physiological and psychological reliance on hallucinogenic substances.

Apply this code when a patient meets diagnostic criteria for hallucinogen dependence and also presents with a mood disorder that is clearly documented as being induced by the hallucinogen use. Documentation should explicitly link the onset and exacerbation of the mood symptoms to the substance. This code is appropriate for both acute and chronic presentations of this dual diagnosis.

• Ensure documentation clearly distinguishes between a pre-existing mood disorder and one induced by hallucinogen use.
• Do not use this code if the mood disorder is merely exacerbated by hallucinogen use but was present prior to substance initiation.
• Always sequence this code first when it is the primary reason for the encounter, followed by any associated physical complications.
