Other secondary chronic gout, left hand, with tophus (tophi)

This code signifies a chronic form of gout that is secondary to another underlying condition, specifically affecting the left hand. The presence of tophi, which are deposits of uric acid crystals, is a key feature of this diagnosis, indicating advanced disease.

Apply this code when documentation clearly states chronic gout of the left hand with tophaceous deposits, and the gout is explicitly identified as secondary. This typically occurs in patients with long-standing hyperuricemia or conditions that impair uric acid excretion. Supporting documentation should include physician notes detailing the location, chronicity, and presence of tophi.

• Ensure documentation specifies "secondary" gout; otherwise, a primary gout code may be more appropriate.
• Verify the laterality (left hand) and the presence of tophi are explicitly stated in the medical record.
• Always code the underlying condition causing the secondary gout first, if known and documented.
