Idiopathic chronic gout, right wrist, with tophus (tophi)

This code signifies a persistent, primary form of gout affecting the right wrist, characterized by the presence of tophi. Tophi are visible or palpable deposits of monosodium urate crystals, indicating advanced or chronic gout.

Apply this code when documentation confirms a diagnosis of idiopathic (primary) chronic gout specifically impacting the right wrist, and the presence of tophaceous deposits is noted. This typically occurs in patients with long-standing hyperuricemia and recurrent gout attacks.

• Ensure documentation explicitly states "idiopathic" or "primary" gout and specifies the "right wrist" as the affected joint.
• Confirm the presence of "tophus" or "tophi" in the clinical notes; otherwise, a non-tophaceous code might be more appropriate.
• Sequence this code first if it represents the primary reason for the encounter.
