Drug-induced chronic gout, unspecified site, without tophus

This code signifies a persistent form of gout that has developed as a direct consequence of medication use, affecting an unspecified joint or location in the body. It specifically indicates the absence of visible or palpable urate crystal deposits (tophi). The condition involves recurrent episodes of acute inflammatory arthritis due to elevated uric acid levels, triggered by an exogenous pharmaceutical agent.

Apply this code when documentation clearly states a diagnosis of chronic gout that is explicitly linked to drug therapy, and there is no mention of tophaceous deposits. This is appropriate for patients experiencing ongoing symptoms or requiring long-term management for drug-induced gout without visible tophi. Supporting documentation should include a history of medication use implicated in gout development and clinical findings consistent with chronic gout.

• Ensure documentation specifies "drug-induced" and "chronic" gout, as well as the absence of tophi.
• Do not use this code if the gout is acute, idiopathic, or if tophi are present; different codes exist for those scenarios.
• Always sequence this code after the code for the adverse effect of the drug, if applicable, to fully describe the etiology.
