Other secondary gout, left ankle and foot

This code signifies a diagnosis of gout that has developed as a consequence of another underlying medical condition or medication, specifically affecting the left ankle and foot. It indicates the presence of uric acid crystal deposition in these joints, leading to inflammation and pain, but where the primary cause is not idiopathic gout.

Use this code when documentation clearly states "secondary gout" affecting the left ankle and foot, and an underlying cause such as renal insufficiency, diuretic use, or myeloproliferative disorders is identified. This code is appropriate when the physician explicitly links the gout to another condition or treatment.

• Always code the underlying primary condition causing the secondary gout first.
• Distinguish carefully between primary (idiopathic) gout and secondary gout; documentation must specify "secondary."
• Ensure the laterality (left) and specific anatomical site (ankle and foot) are clearly documented to support this specific code.
