I25.41

I25.41 — Coronary artery aneurysm

Billable / specific codeICD-10-CM

I25.41 is a billable, specific ICD-10-CM code for coronary artery aneurysm. It is valid for submission on a claim.

congenital coronary (artery) aneurysm (Q24.5)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Coronary arteriovenous fistula, acquired

Excludes2 inherited from the categories above I25.41

Also inherited, and the opposite of Excludes1: these conditions are not part of I25.41, but a patient can have both, so you may code both.

Risk adjustment

I25.41 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

I25.41 is named in 28 Medicare coverage policies — 28 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
