Other secondary gout, right ankle and foot

This code signifies a form of gout that develops as a consequence of another underlying medical condition or medication, specifically affecting the right ankle and foot. It indicates the presence of uric acid crystal deposition and inflammation in these joints, secondary to a primary cause.

Apply this code when documentation clearly states "secondary gout" affecting the right ankle and foot, and an underlying cause (e.g., renal insufficiency, diuretic use, myeloproliferative disorders) is identified. Ensure the physician explicitly links the gout to the secondary condition.

• Always code the underlying primary condition causing the secondary gout first.
• Distinguish carefully between primary gout and secondary gout; this code is only for the latter.
• Verify laterality (right vs. left) and joint specificity (ankle and foot) are clearly documented.
