What This Code Means

Hardening and narrowing of a surgical bypass graft in the right leg without gangrene, causing reduced blood flow to the extremity.

Coding Tips

•Confirm that gangrene is NOT present; if gangrene exists, use codes I70.761 or I70.762 instead
•Document the specific manifestations (claudication, rest pain, ulceration) to support medical necessity

Clinical Significance

Other atherosclerosis of other type bypass graft of the extremities (right leg) captures peripheral arterial disease manifestations in bypass grafts that do not fit the specific categories of claudication, rest pain, ulceration, or gangrene. This may include findings such as bypass graft stenosis, diminished pulses through the graft, or other documented atherosclerotic changes not yet causing limb-threatening ischemia. While less severe than rest pain or tissue loss, this still represents significant vascular disease requiring ongoing surveillance and management.

Documentation Requirements

✓Documented atherosclerotic disease of other type bypass graft(s) with manifestation other than claudication, rest pain, ulceration, or gangrene
✓Laterality documented: right leg
✓Type of bypass graft specified (synthetic, composite, or other non-vein/non-biological type)
✓Specific findings described (graft stenosis, abnormal vascular studies, diminished graft flow)
✓Current management plan (surveillance imaging, antiplatelet therapy, consideration for revision)
