I25.731

I25.731 — Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with angina pectoris with documented spasm

Billable / specific codeICD-10-CM

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)

Excludes1 inherited from the categories above I25.731

These are not written on I25.731, but they bind it: a note on a category applies to every code beneath it. Billing I25.731 with anything listed here is a denial.

Written on I25.7 — Atherosclerosis of coronary artery bypass graft(s) and coronary artery of transplanted heart with angina pectoris

atherosclerosis of bypass graft(s) of transplanted heart without angina pectoris (I25.812)
atherosclerosis of coronary artery bypass graft(s) without angina pectoris (I25.810)
atherosclerosis of native coronary artery of transplanted heart without angina pectoris (I25.811)

Excludes2 inherited from the categories above I25.731

Also inherited, and the opposite of Excludes1: these conditions are not part of I25.731, but a patient can have both, so you may code both.

non-ischemic myocardial injury (I5A)

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.
