Poisoning by quinoline and hydroxyquinoline derivatives

This code signifies an adverse health effect resulting from exposure to or ingestion of quinoline or hydroxyquinoline derivative medications or substances. This includes both accidental and intentional poisonings, leading to toxic effects on various organ systems.

Use this code when documentation clearly states a patient's condition is due to poisoning by a quinoline or hydroxyquinoline derivative. This typically involves overdose, adverse drug reactions, or toxic exposure to these compounds. Supporting documentation should include the specific substance involved and the resulting clinical manifestations.

• Always sequence a T-code (e.g., T40-T50 for poisoning by drugs) as the primary diagnosis, followed by this ICD-9-CM code as a secondary diagnosis to specify the type of poisoning.
• Distinguish between poisoning (adverse effect due to overdose or wrong substance) and adverse effect of a correctly administered drug (which would use different ICD-9-CM codes).
• Ensure the documentation specifies a quinoline or hydroxyquinoline derivative; do not use for other drug classes.
