Poisoning by antimalarials and drugs acting on other blood protozoa

This code signifies an adverse effect resulting from the ingestion or exposure to medications primarily used to treat malaria or other blood protozoal infections. This includes both accidental and intentional poisonings, leading to toxic effects on the patient's system.

Use this code when documentation clearly indicates a patient is experiencing symptoms of poisoning due to an antimalarial drug (e.g., chloroquine, quinine) or other agents targeting blood protozoa. This applies to overdose, incorrect dosage, or adverse reactions manifesting as toxicity. Supporting documentation should detail the substance involved and the resulting clinical presentation.

• Always code the specific manifestation of the poisoning (e.g., cardiac arrhythmias, neurological symptoms) first, followed by this poisoning code.
• Distinguish between poisoning (adverse effect due to overdose/toxicity) and adverse effect in therapeutic use (e.g., expected side effects at correct dosage).
• Ensure documentation specifies the drug class to differentiate from poisoning by other drug types.
