Lead-induced gout, unspecified hip

This code signifies gout that has developed as a direct consequence of lead exposure, specifically affecting an unspecified hip joint. It indicates the presence of uric acid crystal deposition in the joint, leading to inflammation and pain, with lead poisoning identified as the underlying cause.

Use this code when documentation clearly links the patient's gout to lead toxicity and the affected joint is the hip, but the specific side (left or right) is not documented. Supporting documentation should include a diagnosis of gout, evidence of lead exposure or elevated lead levels, and involvement of the hip joint.

• Ensure documentation explicitly states "lead-induced" gout; otherwise, a different gout code may be more appropriate.
• If the specific hip (left or right) is documented, use the more specific M10.151 or M10.152 code.
• Code an external cause code (e.g., from Chapter 20) to identify the source of the lead exposure, if known and documented.
