Unsp athscl nonbiol bypass of the extrm, bilateral legs

This code signifies the presence of atherosclerosis within a nonbiological bypass graft in both legs, where the specific type or extent of the atherosclerosis is not documented. It indicates a hardening and narrowing of these artificial vessels due to plaque buildup, affecting blood flow to the lower extremities. This condition can lead to complications such as limb ischemia.

Use this code when documentation specifies atherosclerosis of a nonbiological bypass graft in both lower extremities, but the physician does not provide further detail regarding the nature or severity of the atherosclerosis. This code is appropriate when the patient presents with symptoms related to graft occlusion or stenosis, and imaging confirms atherosclerotic changes in the bilateral nonbiological leg grafts.

• Ensure documentation explicitly states "nonbiological" graft to differentiate from biological grafts.
• Confirm that the atherosclerosis affects both legs; if unilateral, a different code is required.
• If the type of atherosclerosis (e.g., calcified, thrombotic) is specified, a more precise code should be used.
