Poisoning by cannabis, accidental (unintentional), init

This code signifies an acute, unintended adverse reaction to cannabis, such as an overdose or unexpected intoxication. It describes situations where a patient has inadvertently consumed cannabis or consumed a higher dose than intended, leading to harmful effects.

Apply this code when documenting a patient presenting with symptoms of cannabis poisoning due to accidental ingestion, inhalation, or other exposure. This includes scenarios like a child accidentally consuming edibles or an adult unintentionally taking too much of a cannabis product. It is specifically for the initial presentation and treatment of the poisoning.

• Ensure documentation clearly states the poisoning was accidental and not intentional self-harm or assault.
• Confirm this is the patient's first encounter for this specific poisoning episode; subsequent encounters will require a different seventh character.
• Always code any associated signs and symptoms of the poisoning, such as altered mental status or tachycardia, in addition to this code.
