Poisoning by amphetamines, undetermined, initial encounter

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

Apply this code when a patient presents with symptoms of amphetamine toxicity, and documentation explicitly states or strongly implies that the intent of the exposure is unknown or unconfirmed. This is appropriate for the initial encounter for this specific poisoning event.

• Ensure documentation clearly supports "undetermined" intent; otherwise, a more specific intent code should be used.
• Always assign an additional code for the specific manifestations of the poisoning, if applicable.
• The "A" seventh character indicates an initial encounter for active treatment of the poisoning.
