Lead-induced gout, right ankle and foot

This code signifies an inflammatory arthritis of the right ankle and foot caused by elevated lead levels in the body. It represents a specific form of gout where lead exposure is the underlying etiology, leading to uric acid crystal deposition in the joints.

Apply this code when documentation clearly indicates a diagnosis of gout in the right ankle and/or foot, and a direct causal link to lead poisoning or chronic lead exposure is established. Supporting documentation should include laboratory findings confirming elevated lead levels and a physician's statement linking the lead to the gout.

• Ensure documentation specifies "lead-induced" to differentiate from other forms of gout.
• Always code the underlying lead poisoning (e.g., T56.0X1- for lead and its compounds) as a primary or secondary diagnosis, depending on the encounter.
• Do not use this code for gout not explicitly linked to lead exposure; instead, use codes from the M10.0- series for idiopathic gout.
