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

This code signifies the presence of atherosclerosis affecting a bypass graft in an extremity, specifically when the patient is experiencing rest pain. It indicates a failure or complication of a previously placed vascular graft in a limb due to plaque buildup, leading to ischemic pain even at rest. The "other extremity" specifies that the affected limb is not further defined as right or left.

Use this code when documentation clearly states atherosclerosis of an extremity bypass graft, accompanied by rest pain, and the specific limb (e.g., right or left) is not specified. This typically applies to patients with peripheral artery disease who have undergone bypass surgery and are now experiencing graft failure with severe ischemic symptoms. Supporting documentation would include physician notes detailing the graft type, location, evidence of atherosclerosis, and the presence of rest pain.

• Ensure documentation specifies "rest pain" as opposed to claudication, as this impacts code selection.
• Verify the type of bypass graft (e.g., autologous vein, synthetic) if specified, though this code is for "other type."
• Do not use if the specific extremity (right or left) is documented; instead, choose a more specific code from the I70.72- series.
