Poisoning by methamphetamines accidental, sequela

This code signifies the long-term effects or complications arising from an accidental overdose or exposure to methamphetamines. It indicates that the acute poisoning event has resolved, but the patient is still experiencing residual health issues directly attributable to that unintentional methamphetamine intoxication.

Apply this code when documenting conditions such as chronic organ damage (e.g., cardiomyopathy, renal failure), neurological deficits (e.g., persistent tremors, cognitive impairment), or psychiatric sequelae (e.g., chronic psychosis, severe depression) that are a direct result of a past accidental methamphetamine poisoning. This code is appropriate for follow-up care after the acute poisoning has been treated.

• Always use in conjunction with a code for the specific sequela being treated (e.g., I42.7 for cardiomyopathy).
• Ensure documentation clearly links the current condition to a past accidental methamphetamine poisoning.
• Distinguish from acute poisoning (T43.651A) or subsequent encounters for acute poisoning (T43.651D).
