Poisoning by oth psychodysleptics, undetermined, subs encntr

This code indicates a patient presenting with adverse effects from an unspecified hallucinogenic substance, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. This particular code is used for encounters following the initial treatment of the poisoning.

Apply this code when a patient is seen for follow-up care, complications, or sequelae related to a previously treated poisoning by an unknown hallucinogen, and the circumstances surrounding the poisoning remain unclear. This could include ongoing symptoms, monitoring for long-term effects, or managing related conditions.

• Requires an additional code for the specific adverse effect or manifestation of the poisoning.
• The 7th character "D" signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Distinguish from initial encounters ("A") or sequela ("S") based on the patient's current phase of treatment.
