I24.8 — Other forms of acute ischemic heart disease
I24.8 is a non-billable header ICD-10-CM code for other forms of acute ischemic heart disease. 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.
- myocardial infarction due to demand ischemia (I21.A1)
Excludes1 inherited from the categories above I24.8
These are not written on I24.8, but they bind it: a note on a category applies to every code beneath it. Billing I24.8 with anything listed here is a denial.
Excludes2 inherited from the categories above I24.8
Also inherited, and the opposite of Excludes1: these conditions are not part of I24.8, but a patient can have both, so you may code both.
Written on I24 — Other acute ischemic heart diseases
- non-ischemic myocardial injury (I5A)
Risk adjustment
I24.8 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
I24.8 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
