Figure. Proportion of Medicare Beneficiaries With End-Stage Renal Disease (ESRD) Who Were Enrolled in Medicare Advantage in 2019-2021.

Figure.

A, The numerator is the monthly number of all Medicare beneficiaries with ESRD who were enrolled in a Medicare Advantage (MA) plan. The denominator is the monthly number of all Medicare beneficiaries with ESRD. See eTable 3 in the Supplement for monthly counts of Medicare beneficiaries with ESRD between January 2019 and December 2021.

B, For estimates stratified by race and ethnicity, the numerator is the race and ethnicity–specific monthly number of all Medicare beneficiaries with ESRD who were enrolled in an MA plan and the denominator is the monthly number of all Medicare beneficiaries with ESRD from each racial and ethnic group. Race and ethnicity are from the Master Beneficiary Summary File, which uses an algorithm developed by the Research Triangle Institute to classify beneficiaries as Hispanic or Asian or Pacific Islander according to data from the Social Security Administration or whether they have a first or last name that the institute determined was likely Hispanic or Asian.

C, For estimates stratified by dual Medicare-Medicaid coverage, the numerator is the monthly number of all Medicare beneficiaries with ESRD who were enrolled in an MA plan and who had dual Medicare-Medicaid coverage for at least 1 month in a calendar year, and the denominator is the monthly number of all Medicare beneficiaries with ESRD with dual Medicare-Medicaid coverage for at least 1 month in a calendar year.
