Chronic gout due to renal impairment, right hip, with tophus

This code signifies a chronic inflammatory arthritis affecting the right hip joint, specifically caused by the accumulation of uric acid crystals due to impaired kidney function. The presence of tophi, which are visible or palpable deposits of uric acid, further characterizes this condition.

Apply this code when documentation clearly states chronic gout of the right hip, explicitly links it to renal impairment, and notes the presence of tophi. This is typically seen in patients with long-standing kidney disease and uncontrolled hyperuricemia.

• Ensure documentation specifies "chronic" gout and the laterality of the hip (right).
• Verify the causal link between renal impairment and the gout, and the presence of tophi.
• Code also the underlying renal impairment (e.g., CKD stage) to provide a complete clinical picture.
