Drug-induced chronic gout, left shoulder, with tophus

This code signifies chronic gout that has been induced by medication, specifically affecting the left shoulder joint. The presence of tophi, which are deposits of uric acid crystals, further characterizes this chronic condition. This indicates a long-standing and often more severe form of gout.

Use this code when documentation clearly states drug-induced chronic gout impacting the left shoulder and explicitly mentions the presence of tophi. This typically occurs in patients with a history of medication use (e.g., diuretics, aspirin) contributing to hyperuricemia and subsequent gout attacks, now presenting with chronic manifestations and visible or palpable tophaceous deposits.

• Ensure documentation specifies "drug-induced" and not just chronic gout, as this impacts the specificity of the code.
• Verify the affected joint is the "left shoulder" and not another joint or laterality.
• Confirm the presence of "tophus" or "tophi" is explicitly stated; otherwise, a code without tophi would be more appropriate.
