Poisoning by cannabis, assault, subsequent encounter

This code signifies a patient presenting for follow-up care or treatment of complications arising from cannabis poisoning that occurred as a result of an intentional act of harm by another person. The patient is no longer in the acute phase of the poisoning but is still receiving care related to the event.

Apply this code when documenting subsequent encounters for patients who were forcibly administered cannabis or had cannabis administered to them with malicious intent, leading to an overdose or adverse reaction. This would include scenarios like follow-up appointments for persistent symptoms, mental health counseling, or management of long-term physical effects after the initial acute poisoning event.

• Ensure documentation clearly states the poisoning was due to an assault and that this is not the initial encounter for the poisoning.
• Always sequence this code after any codes for the specific manifestations or complications of the cannabis poisoning.
• Verify the encounter type is indeed "subsequent" and not "initial" or "sequela."
