Poisoning by oth antiprotozoal drugs, undetermined, subs

This code signifies an undetermined poisoning event involving antiprotozoal medications other than those specified elsewhere, occurring during a subsequent encounter for treatment. It indicates that the specific intent (accidental, intentional self-harm, assault) of the poisoning could not be determined by the healthcare provider. The patient is receiving ongoing care for the effects of this poisoning.

Apply this code when a patient presents for follow-up care or continued management of poisoning by an antiprotozoal drug (not otherwise specified) where the intent of the poisoning remains unclear. This is appropriate for encounters after the initial acute phase, such as for monitoring organ function, managing lingering symptoms, or follow-up toxicology.

• Ensure the documentation clearly states "undetermined" intent for the poisoning.
• Verify this is a subsequent encounter, not the initial presentation for the acute poisoning.
• Always code the specific antiprotozoal drug if known, using a more specific code if available.
