I25.731 — Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with angina pectoris with documented spasm
I25.731 is a billable, specific ICD-10-CM code for atherosclerosis of nonautologous biological coronary artery bypass graft(s) with angina pectoris with documented spasm. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- angina pectoris with documented spasm without atherosclerosis of nonautologous biological coronary artery bypass graft(s) (I20.1)
Risk adjustment
I25.731 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.
Medicare coverage
I25.731 is named in 56 Medicare coverage policies — 56 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
