Poisoning by cannabis, assault, sequela

This code indicates a long-term or residual effect resulting from a cannabis poisoning that occurred due to an assault. The initial acute poisoning event has resolved, but the patient is now experiencing persistent health issues directly attributable to that past incident.

Apply this code when documenting conditions such as chronic neurological deficits, persistent psychiatric disorders, or organ damage that are a direct consequence of a previous cannabis poisoning inflicted during an assault. This code is used after the acute phase of the poisoning has passed and the sequelae are being treated.

• Always sequence this sequela code after the code for the specific residual condition (e.g., a code for chronic psychosis).
• Ensure documentation clearly links the current condition to a past cannabis poisoning by assault.
• Do not use this code for acute cannabis poisoning or for poisoning due to accidental or intentional self-harm.
