Poisn by antineopl and immunosup drugs, self-harm, sequela

This code signifies a long-term consequence or complication arising from a prior intentional self-poisoning event involving antineoplastic or immunosuppressive medications. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience residual effects directly attributable to that specific act. These sequelae could range from organ damage to chronic neurological issues.

Apply this code when documenting follow-up care for a patient who previously attempted suicide by ingesting antineoplastic or immunosuppressive drugs, and is now presenting with ongoing health problems directly resulting from that attempt. This code is appropriate for chronic conditions or permanent injuries that manifest after the initial acute poisoning treatment has concluded. Do not use for the acute poisoning event itself.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic kidney disease, neurological deficit).
• Ensure documentation clearly links the current condition to the past intentional self-harm poisoning event.
• Do not use this code if the poisoning was accidental or undetermined; specific codes exist for those circumstances.
