BillableOther atherosclerosis of other type of bypass graft(s) of the extremities, bilateral legs
HCC Category Mapping
What This Code Means
Hardening and narrowing of a surgical bypass graft affecting both legs without gangrene, causing reduced blood flow to both extremities.
Coding Tips
- •Verify bilateral involvement is documented and confirm absence of gangrene
- •This code represents chronic atherosclerotic disease; document functional limitations and symptoms
Clinical Significance
Other atherosclerosis of other type bypass graft of the extremities (bilateral legs) 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: bilateral legs
- ✓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)
