Lead-induced chronic gout, left hip, without tophus (tophi)

This code signifies a chronic inflammatory arthritis of the left hip caused by elevated lead levels in the body, specifically without the presence of tophi (urate crystal deposits). The condition is characterized by recurrent episodes of severe pain, swelling, and tenderness in the affected joint.

Use this code when documentation clearly indicates a diagnosis of chronic gout directly attributed to lead exposure, affecting the left hip joint, and explicitly states the absence of tophaceous deposits. This diagnosis typically follows laboratory confirmation of lead toxicity and clinical presentation consistent with gout.

• Ensure documentation specifies "chronic" gout and a clear causal link to lead exposure.
• Verify the affected joint is the "left hip" and that "without tophus" is explicitly stated.
• Distinguish from acute gout or gout due to other etiologies; look for lead levels in the patient's record.
