Poisoning by cannabis, accidental (unintentional), subs

This code signifies an accidental (unintentional) poisoning due to cannabis, where the patient is receiving follow-up care after the initial treatment of the acute effects. This could include ongoing management of residual symptoms, monitoring for complications, or follow-up after discharge from an acute care setting.

Use this code for patients presenting for subsequent care related to an unintentional cannabis poisoning. Examples include a follow-up visit with a primary care physician after an emergency department visit for cannabis intoxication, or a return visit to address lingering neurological or psychological effects from the poisoning.

• The 7th character "D" indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for the initial treatment of the acute poisoning; refer to codes with the "A" (initial encounter) 7th character.
• Consider co-reporting codes for any specific symptoms or complications resulting from the poisoning, if applicable.
