Gout due to renal impairment, unspecified elbow

This code signifies a form of gout that develops as a direct consequence of impaired kidney function, specifically affecting an unspecified elbow joint. Renal impairment leads to elevated uric acid levels, which then crystallize in the joints, causing inflammation and pain characteristic of gout.

Use this code when documentation clearly links the patient's gout in the elbow to an underlying diagnosis of renal impairment. This applies to cases where the kidney dysfunction is identified as the primary cause of the hyperuricemia leading to gout. Supporting documentation should include a diagnosis of gout, involvement of the elbow, and a confirmed diagnosis of renal impairment.

• Always code the underlying renal impairment first, followed by this gout code.
• Ensure documentation specifies "unspecified elbow" if laterality (right/left) is not recorded.
• Distinguish from other forms of gout (e.g., idiopathic, lead-induced) where renal impairment is not the direct cause.
