Chronic gout due to renal impairment, left hip, w/o tophus

This code signifies a chronic inflammatory arthritis affecting the left hip, specifically caused by elevated uric acid levels due to impaired kidney function. The absence of tophi, which are uric acid crystal deposits, is a key characteristic for this specific diagnosis.

Apply this code when documentation clearly indicates chronic gout in the left hip, directly attributed to renal impairment, and explicitly states the absence of tophaceous deposits. This typically occurs in patients with pre-existing chronic kidney disease experiencing recurrent gout flares.

• Ensure documentation specifies "chronic" gout and a clear causal link to "renal impairment."
• Verify the affected joint is the "left hip" and that "without tophus" is explicitly stated or clearly implied.
• Always code the underlying renal impairment concurrently, as it is the etiology of the gout.
