I25.8 — Other forms of chronic ischemic heart disease
Non-billable headerICD-10-CM
I25.8 is a non-billable header ICD-10-CM code for other forms of chronic ischemic heart disease. It cannot be billed on its own: choose one of the more specific child codes below.
Other codes that can never be billed with I25.8
These codes carry an Excludes1 note pointing at I25.8. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I25.8 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
- I77.6Arteritis, unspecified
Risk adjustment
I25.8 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 I25.8
