Other secondary chronic gout, right hand, with tophus

This code signifies a chronic inflammatory arthritis affecting the right hand, caused by elevated uric acid levels, but secondary to another underlying condition or medication. The presence of tophi, which are visible or palpable deposits of uric acid crystals, confirms the chronic and advanced nature of the gout.

Apply this code when documentation specifies chronic gout in the right hand, clearly indicating it is secondary to another etiology (e.g., renal insufficiency, diuretic use). The medical record must also explicitly state the presence of tophi in the right hand. This code is appropriate for patients presenting with chronic pain, swelling, and visible or palpable tophaceous deposits in the right hand.

• Ensure documentation differentiates between primary and secondary gout; this code is specifically for secondary.
• Verify the laterality (right hand) and the presence of tophi are explicitly stated in the physician's notes.
• Code the underlying secondary condition first, followed by this gout code, to accurately reflect the etiology.
