0.000What This Code Means
Buildup of plaque in synthetic bypass grafts of an extremity, but the specific location is not documented.
Coding Tips
- •This is a less specific code; attempt to obtain clarification on which extremity is affected to use a more specific code
- •Use only when the extremity location cannot be determined from the medical record
Clinical Significance
This code captures atherosclerosis affecting nonbiological (synthetic) bypass graft(s) of the extremities in the unspecified 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 (unspecified 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
