Excludes2 inherited from the categories above I60.3

Also inherited, and the opposite of Excludes1: these conditions are not part of I60.3, but a patient can have both, so you may code both.

I60.3 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.
