Poisoning by other psychodysleptics, assault, subs encntr

This code signifies a patient presenting with adverse effects from hallucinogenic substance use, specifically when the exposure was due to an intentional act of assault by another person. The "subsequent encounter" indicates the patient is receiving follow-up care for the poisoning, not the initial treatment.

Apply this code for patients returning for ongoing management of complications or sequelae stemming from a hallucinogen poisoning that occurred as a result of an assault. This could include follow-up for persistent psychological effects, organ damage, or other long-term health issues. It is used after the initial acute phase of treatment has concluded.

• Always sequence this code after the primary diagnosis describing the specific manifestation of the poisoning.
• Ensure documentation clearly supports both the hallucinogen exposure and the assault as the cause.
• Verify the encounter type is indeed "subsequent" and not initial or sequela.
