I23.7 — Postinfarction angina
I23.7 is a billable, specific ICD-10-CM code for postinfarction angina. It is valid for submission on a claim.
Other codes that can never be billed with I23.7
These codes carry an Excludes1 note pointing at I23.7. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I23.7 alone.
Risk adjustment
I23.7 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 229 Unstable Angina and Other Acute Ischemic Heart Disease0.240 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
