Among Medicare Advantage enrollees, the mortality of Hispanic enrollees in Puerto Rico was significantly higher than that of Hispanic enrollees in the US during 2010-2022.

The risk-adjusted 1-year mortality rate was not different between Medicare Advantage and traditional Medicare beneficiaries with kidney failure who initiated dialysis.

Medicare Advantage enrollees, particularly those with lower out-of-network benefits, may have restricted access to top-ranked hospitals for complex cancer care compared with traditional Medicare enrollees.
