Other secondary chronic gout, unsp wrist, without tophus

This code signifies a chronic form of gout that has developed as a consequence of another underlying condition, affecting an unspecified wrist joint. Importantly, there is no evidence of tophi, which are characteristic urate crystal deposits, associated with this presentation.

Apply this code when documentation clearly indicates chronic gout in the wrist, secondary to another disease process, and specifically states the absence of tophaceous deposits. This is appropriate when the specific wrist (right or left) is not documented. Supporting documentation would include physician notes detailing the chronic nature of the gout, its secondary etiology, and a physical exam or imaging report confirming no tophi.

• Ensure documentation specifies "chronic" gout and a secondary cause; acute gout or primary gout would use different codes.
• Verify the absence of tophi; if tophi are present, a different code from the M1A.43 series would be more appropriate.
• If the specific wrist (right or left) is documented, use a more specific code from the M1A.43 series (e.g., M1A.4310 for right wrist).
