Other secondary chronic gout, right shoulder, with tophus

This code signifies a chronic inflammatory arthritis affecting the right shoulder joint, caused by elevated uric acid levels, and characterized by the presence of tophi. Tophi are deposits of uric acid crystals that form visible or palpable nodules, indicating long-standing and poorly controlled gout. This specific diagnosis points to a secondary form of gout, meaning it's a consequence of another underlying condition or medication.

Apply this code when documentation clearly indicates chronic gout affecting the right shoulder, with the presence of tophaceous deposits. The medical record should specify that the gout is secondary to another condition (e.g., renal insufficiency, certain medications) and not primary. Supporting documentation includes imaging reports confirming tophi, joint aspiration results showing uric acid crystals, and physician notes detailing chronic right shoulder pain and swelling consistent with gout.

• Ensure documentation specifies "secondary" gout; otherwise, a primary gout code would be more appropriate.
• Verify the affected joint is the right shoulder and that tophi are explicitly mentioned.
• Do not confuse with acute gout flares; this code is for chronic, tophaceous disease.
