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

This code signifies a chronic inflammatory arthritis affecting the right elbow, 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 indicates chronic gout in the right elbow, explicitly linking its etiology to renal impairment. The medical record must also confirm the presence of tophaceous deposits in the affected joint.

• Ensure documentation specifies "chronic" gout and the specific joint (right elbow) is affected.
• Verify that the physician explicitly states the gout is "due to renal impairment" and not another cause.
• Confirm the presence of "tophus" or "tophi" in the right elbow for accurate coding.
