Hallucinogen use, unsp w unsp hallucinogen-induced disorder

This code signifies a diagnosis of hallucinogen use where the specific type of hallucinogen is not documented, and the patient is experiencing an unspecified hallucinogen-induced mental or behavioral disorder. It indicates a direct link between the hallucinogen use and the resulting psychiatric symptoms, but without further diagnostic specificity for either the substance or the disorder.

Use this code when documentation clearly states hallucinogen use and an associated mental or behavioral disorder, but lacks details regarding the specific hallucinogen (e.g., LSD, PCP, ecstasy) or the precise nature of the induced disorder (e.g., psychosis, anxiety, mood disorder). This code is appropriate when the provider has not specified the type of hallucinogen or the specific induced disorder.

• Avoid using this code if the specific hallucinogen or the specific hallucinogen-induced disorder is documented; instead, use a more precise code from the F16 category.
• Ensure documentation explicitly links the hallucinogen use to the induced disorder.
• This code should be used as a last resort when more specific information is unavailable, prompting a query to the provider for clarification if possible.
