What This Code Means

Hardening of arteries in a surgically placed synthetic or other nonbiological bypass graft in an extremity other than the legs.

Coding Tips

•Use for upper extremity grafts or other non-leg locations
•Clearly document which extremity is affected in the medical record

Clinical Significance

This code captures atherosclerosis affecting nonbiological (synthetic) bypass graft(s) of the extremities in the other extremity (e.g., upper extremity) without further specification of severity or manifestation. While this code captures the presence of atherosclerotic disease in bypass grafts, it lacks the clinical specificity of codes indicating claudication, rest pain, ulceration, or gangrene. Providers should be encouraged to document the specific clinical manifestation to support more precise coding and appropriate risk stratification.

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 (other extremity (e.g., upper extremity))
✓History of bypass graft surgery with approximate date or timeframe
✓Current status and monitoring plan for the bypass graft
✓Clinical manifestation should be documented to support more specific coding when possible
✓Vascular assessment findings (pulses, ankle-brachial index, imaging results)
