Other secondary chronic gout, unspecified hand, with tophus

This code signifies a chronic form of gout that has developed as a consequence of another underlying condition, affecting an unspecified hand. A key feature is the presence of tophi, which are deposits of uric acid crystals forming visible nodules under the skin or in joints. This indicates advanced, uncontrolled gout.

Apply this code when documentation specifies chronic gout in the hand that is secondary to another disease process, and explicitly mentions the presence of tophi. This is appropriate when the specific hand (right or left) is not documented. Supporting documentation would include physician notes detailing chronic gout, the secondary nature, hand involvement, and physical exam findings or imaging confirming tophi.

• Ensure documentation clearly distinguishes between primary and secondary gout.
• Verify the presence of tophi is explicitly stated; otherwise, a code without tophi should be used.
• If the specific hand is known, use a more precise code indicating laterality (e.g., M1A.4411 for right hand).
