Athscl nonbiol bypass of the extrm w rest pain, oth extrm

This code signifies atherosclerosis affecting a non-biological (synthetic) bypass graft located in an extremity, specifically when the patient experiences rest pain. This condition indicates significant arterial narrowing or occlusion within the graft, leading to critical limb ischemia symptoms even at rest. The "other extremity" designation implies it's not the right or left lower leg, but could be an arm or another unspecified extremity.

Use this code when documentation clearly states atherosclerosis of a synthetic bypass graft in an extremity, accompanied by rest pain. This typically occurs in patients with a history of peripheral artery disease who have undergone bypass surgery using a prosthetic graft. Supporting documentation should include physician notes detailing the graft type, location, presence of atherosclerosis, and the specific symptom of rest pain.

• Ensure the documentation specifies a non-biological (synthetic) graft, not an autogenous vein graft.
• Confirm the presence of rest pain as a symptom; claudication alone would lead to a different code.
• Verify the affected extremity is not specifically right or left lower leg, as those have more specific codes.
