Oth secondary chronic gout, right ankle and foot, w/o tophus

This code signifies chronic gout that is secondary to another underlying condition, affecting the right ankle and/or foot. It specifically indicates the absence of tophi, which are deposits of uric acid crystals. This condition involves persistent inflammation and pain in the specified joint(s) due to elevated uric acid levels.

Apply this code when documentation clearly states "secondary chronic gout" impacting the right ankle and/or foot, and explicitly notes the absence of tophaceous deposits. This is appropriate for patients with recurrent gout flares or persistent symptoms in the specified area, where the gout is a consequence of another medical condition or medication.

• Ensure documentation specifies "secondary" gout and the laterality (right) and anatomical site (ankle and/or foot).
• Verify the absence of tophi; if tophi are present, a different code from the M1A.47 category would be appropriate.
• Always code the underlying secondary condition first, as this gout is a manifestation of that primary diagnosis.
