0.000What This Code Means
Narrowing of other coronary artery bypass grafts causing chest pain with documented coronary artery spasm.
Coding Tips
- •Documentation must specifically mention spasm or vasospasm to use this code
- •This represents Prinzmetal's or vasospastic angina in the context of bypass graft disease
Clinical Significance
This code identifies atherosclerosis in other types of coronary bypass grafts (e.g., synthetic) with vasospastic angina. Synthetic graft materials may have different endothelial responses and vasoreactivity profiles. The documented spasm indicates that the anginal mechanism involves dynamic vasospasm superimposed on fixed atherosclerotic disease, requiring calcium channel blocker therapy.
Documentation Requirements
- ✓History of CABG with graft type not classified as autologous vein/artery or nonautologous biological
- ✓Evidence of atherosclerosis within the graft
- ✓Documented coronary vasospasm confirmed by clinical presentation or diagnostic testing
- ✓Vasospastic angina pattern documented
- ✓Treatment plan targeting both atherosclerotic disease and vasospasm
Excludes 1 — Do NOT code together
- angina pectoris with documented spasm without atherosclerosis of other coronary artery bypass graft(s) (I20.1)
