Poisoning by antirheumatics, NEC, accidental, sequela

This code signifies a long-term or residual effect stemming from an accidental overdose or poisoning by an antirheumatic medication that is not specified elsewhere. These are conditions that persist after the acute phase of the poisoning has resolved, such as chronic organ damage or neurological deficits.

Use this code when documenting a patient presenting with a current health problem that is a direct consequence of a past, unintentional poisoning by an antirheumatic drug. This applies to follow-up visits or admissions where the focus is on managing the sequelae, not the acute poisoning event itself.

• Always sequence this code after the code describing the specific sequela (e.g., chronic kidney disease, neuropathy).
• Ensure the medical record clearly links the current condition to a past accidental antirheumatic poisoning.
• Do not use for acute poisoning events; those require codes from the initial encounter (A) or subsequent encounter (D) categories.
