I01.8 — Other acute rheumatic heart disease
I01.8 is a billable, specific ICD-10-CM code for other acute rheumatic heart disease. It is valid for submission on a claim.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Any condition in I00 with other or multiple types of heart involvement
- Acute rheumatic pancarditis
Risk adjustment
I01.8 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
I01.8 is named in 12 Medicare coverage policies — 12 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
