I70.703
BillableUnspecified atherosclerosis of other type of bypass graft(s) of the extremities, bilateral legs
HCC Category Mapping
What This Code Means
Plaque buildup in non-synthetic bypass grafts affecting both legs without specific symptoms documented.
Coding Tips
- •Bilateral coding requires documentation confirming involvement of both legs
- •If claudication or other complications are documented, use I70.713 instead
Clinical Significance
This code captures atherosclerosis affecting other type bypass graft(s) of the extremities in the bilateral lower extremities 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 other type bypass graft(s)
- ✓Type of bypass graft material documented (synthetic/nonbiological vs. other type such as composite or mixed-material graft)
- ✓Laterality clearly documented (bilateral lower extremities)
- ✓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)
