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

This code describes a chronic inflammatory arthritis affecting the right hip joint, specifically caused by the accumulation of uric acid crystals due to impaired kidney function. The absence of tophi, which are visible or palpable uric acid deposits, is a key characteristic.

Apply this code when documentation clearly indicates chronic gout in the right hip, directly attributed to renal impairment, and explicitly states the absence of tophaceous deposits. Supporting documentation would include physician notes detailing the patient's history of gout, chronic kidney disease, and physical examination findings specific to the right hip.

• Ensure documentation specifies "chronic" gout and the "right hip" as the affected joint.
• Verify that the physician explicitly links the gout to "renal impairment" and confirms "without tophus."
• Do not use this code if tophi are present; a different subcategory for tophaceous gout would be appropriate.
