Lead-induced gout, multiple sites

This code signifies gout that has developed as a direct result of lead poisoning, affecting multiple joints throughout the body. It indicates a systemic inflammatory response to lead accumulation, leading to uric acid crystal deposition in various articular sites.

Apply this code when documentation clearly links the patient's gout to lead exposure and specifies involvement of more than one joint. Supporting documentation should include a diagnosis of gout, evidence of lead toxicity (e.g., elevated blood lead levels), and a physician's statement confirming the causal relationship.

• Ensure the medical record explicitly states "lead-induced" gout, not just gout in a patient with lead exposure.
• Verify that multiple joint sites are documented; otherwise, a site-specific code for lead-induced gout may be more appropriate.
• Always code the underlying lead poisoning (e.g., T56.0X1-) as a primary or secondary diagnosis, depending on the encounter's focus.
