Gout due to renal impairment, unspecified ankle and foot

This diagnosis code signifies gout that has developed as a direct consequence of impaired kidney function, affecting an ankle or foot where the specific side (right or left) is not documented. It indicates a secondary form of gout where the underlying renal issue contributes to the accumulation of uric acid.

Use this code when documentation explicitly links a patient's gout in the ankle or foot to their renal impairment, and the specific ankle or foot affected is not specified. This typically occurs in patients with chronic kidney disease or other conditions leading to reduced uric acid excretion.

• Ensure documentation clearly states the causal link between renal impairment and gout.
• Avoid using this code if the specific ankle or foot (right or left) is documented; instead, choose a more specific code.
• Always code the underlying renal impairment first, followed by this code for the manifestation.
