Poisoning by methamphetamines accidental, init

This code signifies an accidental overdose or adverse reaction to methamphetamine, resulting from unintentional exposure or misadministration. It indicates that the patient experienced poisoning due to the substance, not therapeutic use, and the event was not deliberate.

Apply this code when a patient presents with symptoms of methamphetamine toxicity due to an unintentional ingestion, inhalation, or injection. This includes scenarios where the patient mistakenly took methamphetamine, or was unknowingly exposed to it, and is receiving initial treatment for the poisoning.

• Ensure documentation clearly states the poisoning was accidental and not intentional self-harm or assault.
• Always assign a T-code first for poisoning, followed by codes for any associated manifestations.
• Verify this is the patient's initial encounter for this specific poisoning event. Subsequent encounters will require different seventh characters.
