Lead-induced gout, right knee

This code signifies an inflammatory arthropathy of the right knee caused by elevated lead levels in the body. It represents a specific type of gout where lead exposure is identified as the underlying etiology.

Apply this code when documentation clearly states gout affecting the right knee and explicitly links it to lead toxicity. This diagnosis requires evidence of both gouty arthritis and a confirmed history or presence of lead poisoning.

• Ensure documentation specifies "lead-induced" gout; otherwise, use codes for idiopathic gout.
• Always sequence a code for the underlying lead poisoning (e.g., T56.0X1A) before this code.
• Verify laterality (right knee) is clearly documented; if not specified or bilateral, choose the appropriate unspecified or bilateral code.
