Other secondary chronic gout, left elbow, with tophus

This code signifies a chronic form of gout that is secondary to another underlying condition, specifically affecting the left elbow. The presence of tophi, which are deposits of uric acid crystals, indicates a more advanced or severe manifestation of the disease in this joint.

Use this code when documentation confirms chronic gout in the left elbow, explicitly stated as secondary, and notes the presence of tophaceous deposits. This typically occurs in patients with long-standing hyperuricemia or other conditions contributing to gout.

• Ensure documentation specifies "secondary" gout and not primary gout.
• Verify the affected joint is the left elbow and that tophi are present.
• Code the underlying cause of the secondary gout first, if known and documented.
