Lead-induced gout, unspecified wrist

This code describes a form of inflammatory arthritis caused by elevated lead levels, specifically affecting an unspecified wrist joint. It is characterized by the deposition of uric acid crystals in the joint, leading to acute pain, swelling, and tenderness. This condition is a direct consequence of lead toxicity impacting uric acid metabolism.

Use this code when documentation clearly indicates a diagnosis of gout directly attributed to lead exposure, with the affected joint being the wrist, but without specifying laterality (left or right). Supporting documentation should include evidence of elevated lead levels and clinical findings consistent with gout in the wrist.

• Ensure documentation explicitly links the gout to lead exposure; otherwise, a different gout code may be more appropriate.
• If laterality of the wrist is specified (left or right), use the more specific codes M10.131 or M10.132.
• Always code the underlying lead poisoning (e.g., T56.0X1-T56.0X4) as a primary or secondary diagnosis, depending on the encounter's focus.
