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

This code signifies the presence of atherosclerosis affecting a previously placed bypass graft in the left leg, specifically when the patient is experiencing rest pain. This indicates a significant compromise of blood flow through the graft, leading to ischemic pain even at rest. The graft itself is of a type other than autologous vein or nonautologous biological.

Use this code when documentation confirms atherosclerosis within a bypass graft (not specified as autologous vein or nonautologous biological) in the left lower extremity, and the patient's primary symptom is rest pain. This typically occurs in patients with advanced peripheral artery disease who have undergone revascularization. Supporting documentation should clearly state the location of the graft, the presence of atherosclerosis, and the symptom of rest pain.

• Ensure the documentation specifies "rest pain" as the symptom, not just claudication or other ischemic symptoms.
• Verify the laterality (left leg) and the type of bypass graft (other type) are clearly documented to support this specific code.
• Consider sequencing this code after any underlying peripheral artery disease (e.g., I70.2- series) if it is still present and contributing to the overall condition.
