Medicare Advantage enrollment has increased in the US and Puerto Rico, with a dramatic growth among Puerto Rico beneficiaries with end-stage renal disease.

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.

Medicare Advantage enrollment was higher among immigrants compared with US-born residents, but the highest enrollment was found among immigrants with limited English proficiency.

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