Lead-induced gout, unspecified knee

This code signifies an inflammatory arthritis resulting from elevated lead levels, specifically affecting an unspecified knee joint. It indicates the presence of gout where lead exposure is identified as the underlying cause.

Apply this code when documentation clearly states a diagnosis of lead-induced gout and specifies involvement of the knee, without further detail on laterality. Supporting documentation would include laboratory findings confirming elevated lead levels and clinical notes detailing gout symptoms localized to the knee.

• Ensure documentation explicitly links gout to lead exposure; otherwise, use a code for primary gout.
• If laterality (right or left knee) is specified, use the more specific code (M10.161 or M10.162).
• Sequence this code after the code for lead toxicity (e.g., T56.0X1-T56.0X4) if the lead exposure is acute or ongoing.
