Hallucinogen use, unspecified, uncomplicated

This code signifies the use of a hallucinogenic substance without any specified pattern of use (e.g., abuse, dependence) and without any associated physical or mental health complications. It indicates a documented instance of hallucinogen use where further details regarding the nature or impact of the use are absent.

This code is appropriate when a patient's medical record clearly indicates hallucinogen use, but the provider has not documented whether it constitutes abuse, dependence, or is associated with intoxication, withdrawal, or other disorders. It is typically used for initial encounters or when documentation is insufficient to assign a more specific code.

• Only use when documentation explicitly states "unspecified" or lacks further detail regarding the pattern or complications of hallucinogen use.
• Avoid using if the documentation supports hallucinogen abuse (F16.1-) or dependence (F16.2-).
• Always review the entire medical record for more specific information before assigning this unspecified code.
