Other codes that can never be billed with I47.11
These codes carry an Excludes1 note pointing at I47.11. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I47.11 alone.
- R00.0Tachycardia, unspecified
Risk adjustment
I47.11 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
I47.11 is named in 33 Medicare coverage policies — 33 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
