Lead-induced chronic gout, multiple sites, without tophus

This diagnosis code signifies a chronic inflammatory arthritis caused by elevated lead levels, affecting multiple joints throughout the body. It specifically indicates that the characteristic crystal deposits (tophi) are not present. The condition results in recurrent episodes of severe joint pain, swelling, and tenderness.

Apply this code when documentation confirms a diagnosis of chronic gout directly attributed to lead exposure, with evidence of polyarticular involvement. This code is appropriate when the physician explicitly states the absence of tophaceous deposits. Supporting documentation should include lead level testing results and clinical findings consistent with chronic gout.

• Ensure documentation clearly links lead exposure as the etiology of the chronic gout.
• Verify the absence of tophi is explicitly stated; otherwise, a code indicating tophi may be more appropriate.
• Sequence this code after any codes for the underlying lead poisoning, if applicable and still active.
