Chronic gout due to renal impairment, right hand, w tophus

This code signifies a chronic form of gout that has developed as a direct consequence of impaired kidney function. The right hand is specifically affected, and the presence of tophi (deposits of uric acid crystals) is a key diagnostic feature. This condition indicates long-standing hyperuricemia leading to crystal deposition in the joints and surrounding tissues.

Use this code when documentation clearly states chronic gout caused by renal impairment, with specific involvement of the right hand, and the presence of tophaceous deposits. This typically applies to patients with a history of chronic kidney disease and clinical or imaging evidence of gouty tophi in the specified location. Supporting documentation includes physician notes detailing the etiology, location, and presence of tophi.

• Always confirm the causal link between renal impairment and the gout; if not explicitly stated, query the provider.
• Verify the specific joint involved (right hand) and the presence of tophi, as other codes exist for different locations or absence of tophi.
• Sequence this code after the underlying chronic kidney disease (CKD) code to accurately reflect the etiology.
