Poisoning by oth antiprotozoal drugs, accidental, sequela

This code signifies a long-term or residual effect resulting from an accidental overdose or adverse reaction to antiprotozoal medications other than those specifically classified elsewhere (e.g., antimalarials, other specified antiprotozoals). These sequelae are the lasting health problems that persist after the initial poisoning event has resolved.

Apply this code when documenting chronic conditions, permanent organ damage, or persistent neurological deficits directly attributable to an unintentional poisoning by an antiprotozoal drug. This is used after the acute phase of the poisoning has passed, and the patient is being treated for the ongoing consequences.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease, neuropathy).
• Ensure documentation clearly links the current condition to a past accidental antiprotozoal poisoning.
• Verify that the antiprotozoal drug involved is not more specifically classified under another T37 subcategory.
