I24 — Other acute ischemic heart diseases
I24 is a non-billable header ICD-10-CM code for other acute ischemic heart diseases. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- non-ischemic myocardial injury (I5A)
Other codes that can never be billed with I24
These codes carry an Excludes1 note pointing at I24. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I24 alone.
Risk adjustment
I24 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 I24
4 child codes. Green means billable.
