0.000What This Code Means
Plaque buildup in a bypass graft of a transplanted heart, causing unstable chest pain.
Coding Tips
- •Verify the patient has had a heart transplant and the atherosclerosis is in a bypass graft of the transplanted heart
- •Distinguish from atherosclerosis in native coronary arteries of the transplanted heart
Clinical Significance
This code captures atherosclerotic disease in a bypass graft of a coronary artery in a transplanted heart with unstable angina. This represents a highly complex clinical scenario — a patient who has undergone both heart transplantation and subsequent coronary artery bypass grafting, with acute ischemic decompensation. These patients have extremely limited remaining therapeutic options and require specialized cardiac transplant center management.
Documentation Requirements
- ✓Confirmed heart transplant history
- ✓History of coronary artery bypass grafting performed after heart transplantation
- ✓Evidence of atherosclerotic disease in the bypass graft of the transplanted heart
- ✓Documentation of unstable angina pattern in the transplant recipient
- ✓Emergent management plan in the context of the transplant and post-CABG status
