Gout due to renal impairment, right ankle and foot

This code signifies a form of gout specifically caused by impaired kidney function, affecting the right ankle and/or foot. It indicates the presence of urate crystal deposition in these joints, leading to inflammation and pain, directly attributable to the kidneys' inability to adequately excrete uric acid.

Apply this code when documentation clearly links the patient's gout in the right ankle and/or foot to an underlying renal impairment. This typically involves elevated serum uric acid levels in conjunction with a diagnosis of chronic kidney disease or other renal dysfunction, and clinical signs of gout in the specified anatomical location.

• Ensure documentation explicitly states "gout due to renal impairment" and specifies the right ankle and/or foot as the affected site.
• Do not use this code for primary gout or gout due to other secondary causes; those have distinct codes.
• Always code the underlying renal impairment concurrently to fully describe the patient's condition.
