Poisoning by uric acid metabolism drugs

This code indicates an adverse effect or overdose resulting from medications primarily used to treat conditions related to uric acid metabolism, such as gout or hyperuricemia. This includes drugs like allopurinol, febuxostat, probenecid, or colchicine, when they cause a toxic reaction or unintended consequence. The poisoning can manifest as various systemic effects depending on the specific drug and dosage.

Use this code when documentation clearly states a patient has experienced an adverse reaction, overdose, or toxic effect from a drug intended to modify uric acid levels. This applies to both accidental and intentional poisonings, as well as therapeutic misadventures. Supporting documentation should include the specific drug involved, the nature of the adverse effect, and the causal link to the medication.

• Always sequence this code first when it represents the primary reason for the encounter, followed by codes for the specific manifestations of the poisoning.
• Distinguish between adverse effects (correctly prescribed and administered) and poisoning (overdose, wrong drug, or non-medical use).
• Do not use for allergic reactions to these drugs; instead, refer to codes for adverse effects of drugs, not elsewhere classified.
