0.000What This Code Means
Other types of hardening of arteries in a synthetic bypass graft in the right leg without ulceration or gangrene.
Coding Tips
- •Use this code for atherosclerotic disease of nonbiological bypass grafts without complications like ulceration or gangrene
- •Verify the right leg laterality and confirm the bypass graft is nonbiological
Clinical Significance
This code captures atherosclerosis affecting nonbiological (synthetic) bypass graft(s) of the extremities in the right lower extremity with other specified manifestations not classified elsewhere. This code captures atherosclerotic disease of bypass grafts presenting with clinical findings such as diminished pulses, abnormal ankle-brachial indices, or other objective vascular compromise. Accurate coding of the specific graft type and laterality ensures proper risk adjustment and tracking of post-surgical vascular disease progression.
Documentation Requirements
- ✓Confirmed diagnosis of atherosclerosis affecting nonbiological (synthetic) bypass graft(s)
- ✓Type of bypass graft material documented (synthetic/nonbiological vs. other type such as composite or mixed-material graft)
- ✓Laterality clearly documented (right lower extremity)
- ✓History of bypass graft surgery with approximate date or timeframe
- ✓Current status and monitoring plan for the bypass graft
- ✓Specific manifestation described (e.g., diminished pulses, abnormal ankle-brachial index, atheroembolism)
- ✓Objective vascular assessment findings supporting the diagnosis
- ✓Treatment and monitoring plan documented
