Poisoning by amphetamines, undetermined, sequela

This code signifies a long-term or residual effect resulting from an amphetamine poisoning where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience health problems directly attributable to the past exposure.

Use this code when documenting conditions such as chronic organ damage, neurological deficits, or persistent psychiatric issues that are clearly linked to a previous amphetamine poisoning of unknown intent. This applies when the patient is no longer in the acute phase of intoxication or withdrawal, but rather presenting for treatment of the lasting consequences.

• Always assign an additional code(s) to specify the particular sequela being treated (e.g., chronic kidney disease, psychosis).
• Ensure documentation clearly links the current condition to a past amphetamine poisoning and explicitly states the undetermined intent.
• Do not use for acute poisoning episodes or for current amphetamine abuse/dependence without a documented poisoning event.
