Lead-induced chronic gout, left wrist, without tophus

This code signifies chronic gout specifically caused by lead exposure, affecting the left wrist. It indicates the absence of tophi, which are characteristic urate crystal deposits. The condition is characterized by recurrent episodes of acute arthritis in the left wrist due to elevated uric acid levels linked to lead toxicity.

Use this code when documentation clearly states a diagnosis of chronic gout in the left wrist, explicitly attributing its etiology to lead poisoning. Supporting documentation should include evidence of lead exposure and elevated uric acid levels, along with clinical findings consistent with gout in the specified joint.

• Ensure documentation specifies "chronic" gout and a clear causal link to lead exposure.
• Verify the affected joint is the "left wrist" and that "without tophus" is explicitly stated or implied by the absence of tophi documentation.
• Always code the underlying lead poisoning (e.g., T56.0X1- for lead and its inorganic compounds) as a primary or secondary diagnosis, depending on the encounter's focus.
