Gout due to renal impairment, left shoulder

This code signifies gout that has developed as a direct consequence of impaired kidney function, specifically affecting the patient's left shoulder. It indicates a secondary form of gout where the underlying renal issue leads to hyperuricemia and subsequent urate crystal deposition in the joint.

Apply this code when documentation clearly links the patient's gout in the left shoulder to a diagnosed renal impairment. This typically occurs in patients with chronic kidney disease or other conditions causing reduced uric acid excretion. Supporting documentation should include a diagnosis of gout, laterality of the affected joint, and a confirmed diagnosis of renal impairment identified as the etiology.

• Ensure documentation explicitly states the causal link between renal impairment and gout.
• Do not use for primary gout or gout due to other secondary causes (e.g., medication-induced).
• Always code the underlying renal impairment first, followed by this code, to accurately reflect the etiology.
