Poisoning by methamphetamines, undetermined, init

This code signifies an adverse health event resulting from methamphetamine exposure where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is presenting for the initial treatment of this poisoning.

Apply this code when a patient presents with signs and symptoms of methamphetamine toxicity, and documentation clearly indicates that the circumstances surrounding the exposure are unknown or cannot be definitively classified as accidental, intentional, or assault. This is for the first time the patient is receiving care for this specific poisoning event.

• Always assign an additional code for all manifestations of the poisoning.
• Ensure documentation explicitly states "undetermined" intent or lacks sufficient information to classify intent.
• Do not use this code for adverse effects of properly administered methamphetamines; use codes from the T43.61- category for those scenarios.
