Poisoning by methamphetamines, undetermined, sequela

This code indicates a long-term health consequence or complication arising from a methamphetamine poisoning where the intent (e.g., accidental, intentional self-harm) could not be determined at the time of the original poisoning event. These sequelae are chronic conditions that persist after the acute effects of the poisoning have resolved.

Use this code when documenting a patient presenting with a chronic condition directly attributable to a past methamphetamine poisoning, and the original poisoning's intent was not specified or remains unknown. This applies to conditions like persistent neurological deficits, organ damage, or mental health disorders that are a direct result of the prior exposure.

• Always assign an additional code(s) to specify the exact nature of the sequela (e.g., specific organ damage, neurological deficit).
• Ensure documentation clearly links the current condition to a past methamphetamine poisoning with undetermined intent.
• The "S" in the 7th character indicates sequela and should only be used for conditions that are residual effects.
