I70.702
BillableUnspecified atherosclerosis of other type of bypass graft(s) of the extremities, left leg
HCC Category Mapping
What This Code Means
Plaque buildup in non-synthetic bypass grafts in the left leg without specific symptoms documented.
Coding Tips
- •Confirm the graft type is 'other' (not nonbiological) and laterality is left before assigning this code
- •Review clinical documentation for any functional limitations that would warrant a higher specificity code
Clinical Significance
This code captures atherosclerosis affecting other type bypass graft(s) of the extremities in the left lower 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 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 (left lower 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)
