Poisn by oth nonopio analges/antipyret, NEC, undet, sequela

This code signifies a long-term complication or residual effect resulting from an undetermined poisoning by a non-opioid analgesic or antipyretic medication not specified elsewhere. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing lasting health issues directly attributable to the original event.

Apply this code when documenting a patient presenting with a chronic condition or permanent injury that is a direct consequence of a past poisoning by an unspecified non-opioid pain reliever or fever reducer, and the intent of the poisoning (e.g., accidental, intentional self-harm) could not be determined. This is appropriate for follow-up encounters addressing these persistent sequelae.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease, liver damage).
• Ensure documentation clearly links the current condition to a past poisoning event and specifies the undetermined intent.
• Verify that the medication involved was a non-opioid analgesic or antipyretic not classified under more specific codes.
