Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Atrial premature beats
Risk adjustment
I49.1 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
I49.1 is named in 23 Medicare coverage policies — 23 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
