Poisoning by unsp psychodysleptics, undetermined, subs

This code indicates a poisoning event involving an unspecified hallucinogenic substance where the intent (e.g., accidental, intentional self-harm) cannot be determined. This specific code is used when the patient is receiving follow-up care for the sequelae or complications of the initial poisoning.

This code is appropriate for subsequent encounters when a patient presents for ongoing management of symptoms or complications stemming from an undetermined poisoning by a hallucinogen. Examples include follow-up for persistent psychological effects, organ damage, or other medical issues identified after the initial acute phase. It would be used after the initial treatment for the acute poisoning has concluded.

• Ensure documentation clearly states the encounter is for follow-up care related to the poisoning, not the initial acute treatment.
• Confirm the specific type of hallucinogen is not identified in the medical record; otherwise, a more specific code should be used.
• Verify that the intent of the poisoning remains undetermined; if intent is clarified, a different 6th character (A, P, S) would be appropriate.
