What This Code Means

This code describes a buildup of plaque in a surgical bypass graft (a tube used to reroute blood flow around a blocked artery) in an arm or leg, where the specific type of graft material is not specified. The condition affects blood flow to the extremities and can lead to pain, weakness, or tissue damage if left untreated.

Coding Tips

•Verify documentation specifies the bypass graft is in an extremity (arm or leg) and that the graft type is truly unspecified; if the graft type is documented (e.g., synthetic, vein), use a more specific code
•Confirm which extremity is affected and whether symptoms or complications are present, as these may require additional codes for complete clinical documentation

Clinical Significance

This code captures atherosclerosis affecting other type 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 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 (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)
