Athscl type of bypass of the extrm w rest pain, right leg

This code describes the presence of atherosclerosis, a hardening and narrowing of the arteries due to plaque buildup, specifically affecting a bypass graft in the right leg. The patient is experiencing rest pain, indicating severe limb ischemia even at rest, due to the compromised blood flow through the grafted vessel. This condition signifies a failure or significant deterioration of a previous revascularization procedure.

Use this code when documentation confirms atherosclerosis within a bypass graft (e.g., femoropopliteal bypass, aortobifemoral bypass) in the right lower extremity. The patient must also present with rest pain, a critical symptom indicating advanced peripheral artery disease. Supporting documentation includes vascular studies (e.g., duplex ultrasound, angiography) showing graft stenosis or occlusion, and clinical notes detailing the patient's symptoms of rest pain.

• Ensure the documentation clearly specifies "other type" of bypass graft if not a native artery or autologous vein graft.
• Verify the laterality is explicitly stated as "right leg" and that rest pain is documented, not just claudication.
• Consider sequencing this code after any underlying systemic atherosclerosis codes, if applicable, and before codes for associated complications like ulceration or gangrene.
