Athscl nonaut bio bypass of extrm w intrmt claud, oth extrm

This code signifies the presence of atherosclerosis affecting a non-autologous biological bypass graft in an extremity, leading to symptoms of intermittent claudication. This condition indicates a narrowing or hardening of the graft, impairing blood flow to the limb and causing pain with exertion. The "other extremity" specifies that the affected limb is not the lower leg or foot.

Use this code when documentation confirms atherosclerosis within a bypass graft that originated from a non-autologous biological source (e.g., bovine, porcine) in an extremity, and the patient experiences intermittent claudication. This code is appropriate when the affected extremity is not specifically identified as the lower leg or foot, or when multiple extremities are involved. Supporting documentation should clearly state the type of graft, the presence of atherosclerosis, and the symptom of claudication.

• Ensure the documentation specifies "nonautologous biological" graft; do not use for synthetic or autologous grafts.
• Verify that intermittent claudication is explicitly documented as a symptom.
• Distinguish from codes for atherosclerosis of native arteries or other types of grafts.
