I25.81 — Atherosclerosis of other coronary vessels without angina pectoris
I25.81 is a non-billable header ICD-10-CM code for atherosclerosis of other coronary vessels without angina pectoris. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- atherosclerotic heart disease of native coronary artery without angina pectoris (I25.10)

Other codes that can never be billed with I25.81
These codes carry an Excludes1 note pointing at I25.81. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I25.81 alone.
- T86.290Cardiac allograft vasculopathy
- I25.7Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris
- I25.75Atherosclerosis of native coronary artery of transplanted heart with angina pectoris
- I25.76Atherosclerosis of bypass graft of coronary artery of transplanted heart with angina pectoris
Risk adjustment
I25.81 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code to one of these instead I25.81
3 child codes. Green means billable.
