I25.2 is a billable, specific ICD-10-CM code for old myocardial infarction. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Healed myocardial infarction
- Past myocardial infarction diagnosed by ECG or other investigation, but currently presenting no symptoms
Risk adjustment
I25.2 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
I25.2 is named in 47 Medicare coverage policies — 47 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
