Athscl unsp type bypass of the extrm w rest pain, bi legs

This code signifies atherosclerosis affecting bypass grafts in both lower extremities, leading to ischemic rest pain. It indicates a chronic, progressive hardening and narrowing of the arteries within the surgically created bypasses, resulting in insufficient blood flow to the legs even at rest.

Apply this code when documentation explicitly states atherosclerosis of bypass grafts in both legs, accompanied by rest pain. This typically occurs in patients with a history of peripheral artery disease who have undergone revascularization procedures. Supporting documentation should include physician notes detailing the diagnosis, location (bilateral lower extremities), and the presence of rest pain.

• Ensure the documentation specifies "unspecified type" of bypass graft if no further detail is provided.
• Verify that rest pain is clearly documented; claudication alone would require a different code.
• Confirm the laterality is explicitly bilateral; separate codes exist for unilateral involvement.
