Chronic gout due to renal impairment, left ank/ft, w/o toph

This code signifies chronic inflammatory arthritis caused by hyperuricemia secondary to impaired kidney function, specifically affecting the left ankle and foot. It indicates the absence of visible or palpable urate crystal deposits (tophi) in the affected joint.

Apply this code when documentation confirms a diagnosis of chronic gout directly attributed to renal impairment, localized to the left ankle and foot, and explicitly states the absence of tophi. Supporting documentation should include laboratory findings of elevated serum uric acid, evidence of chronic kidney disease, and clinical notes detailing gout flares or chronic arthropathy in the specified location.

• Ensure documentation clearly links the gout to renal impairment; otherwise, a different etiology code for gout may be appropriate.
• Verify the specific joint involved (left ankle and foot) and the absence of tophi, as these details significantly impact code selection.
• Do not use this code for acute gout flares or gout with tophi; separate codes exist for those presentations.
