Underdosing of other antiprotozoal drugs, subs encntr

This code indicates that a patient is experiencing adverse effects or complications because they have not received enough of an antiprotozoal medication, other than those specifically classified elsewhere. This underdosing is causing a current health issue or exacerbating an existing condition.

Use this code when a patient presents for follow-up care related to the ongoing consequences of insufficient dosing of an antiprotozoal drug (e.g., for giardiasis, amebiasis, or other protozoal infections) that is not a sulfonamide, antimalarial, or other specified antiprotozoal. This applies to situations where the underdosing is actively impacting the patient's health during a subsequent visit.

• Requires an additional code to specify the nature of the adverse effect or complication.
• Distinguish from initial encounters (A) or sequela (S) encounters.
• Ensure the specific antiprotozoal drug involved is not better classified under another T37 subcategory.
