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

This code signifies a diagnosis of chronic gout of unknown origin affecting the left wrist, characterized by the presence of tophi. Tophi are deposits of uric acid crystals that form under the skin or in joints, indicating advanced or poorly controlled gout.

Apply this code when documentation confirms idiopathic chronic gout specifically impacting the left wrist, with clear mention of tophaceous deposits. This is typically used for patients presenting with chronic pain, swelling, and palpable tophi in the left wrist joint.

• Ensure documentation specifies "idiopathic" and "chronic" gout, as well as the presence of tophi.
• Verify the laterality is explicitly stated as "left wrist"; do not assume.
• Distinguish from acute gout or gout due to a secondary cause, which would require different codes.
