0.000What This Code Means
Narrowing of coronary artery bypass grafts without causing chest pain symptoms.
Coding Tips
- •This code indicates atherosclerosis is present but asymptomatic
- •Ensure documentation confirms absence of angina; if any angina is present, use codes with angina specifications
Clinical Significance
This code captures atherosclerosis of coronary artery bypass grafts without associated angina pectoris. This may represent incidental findings on surveillance angiography or CT imaging in asymptomatic post-CABG patients. While the patient is currently asymptomatic from an angina standpoint, the graft disease itself requires monitoring and medical management to prevent progression to symptomatic disease or graft failure.
Documentation Requirements
- ✓History of coronary artery bypass graft surgery
- ✓Evidence of atherosclerotic disease in the bypass graft(s) — angiographic, CT, or clinical documentation
- ✓Explicit documentation that the patient does NOT have angina pectoris currently
- ✓Graft disease management plan including risk factor modification and medications
- ✓Surveillance plan for disease progression
Excludes 1 — Do NOT code together
