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

This code signifies a chronic inflammatory arthritis affecting the left hip, specifically caused by elevated uric acid levels resulting from impaired kidney function. The presence of tophi, which are deposits of uric acid crystals, further characterizes this condition.

Apply this code when documentation clearly states chronic gout in the left hip, explicitly links it to renal impairment, and notes the presence of tophi. This scenario typically involves patients with pre-existing kidney disease experiencing recurrent gout flares and visible or palpable tophaceous deposits.

• Ensure documentation specifies "chronic" gout and explicitly links it to "renal impairment" as the etiology.
• Verify the laterality (left hip) and the presence of "tophus" or "tophi" are clearly stated.
• Remember to also code the underlying renal impairment (e.g., CKD stage) as a secondary diagnosis.
