Repealing and replacing the Affordable Care Act is a top priority of the Trump Administration and the Republican leadership, which could have implications for the Medicare program. This brief provides a side-by-side comparison of the Medicare-related provisions in six bills and proposals that would repeal the ACA, excluding proposals that would not directly affect Medicare.
Medicare Advantage plans, which consist primarily of HMOs and PPOs, now cover almost 18 million people – nearly one-third of all Medicare beneficiaries.
This issue brief analyzes the number and variety of Medicare Advantage plan choices available to beneficiaries in 2017. It describes trends in number of Medicare Advantage plans and plan quality ratings, and new information on plan premiums, out-of-pocket expense limits, and other plan features. This spotlight is part of a series of spotlights tracking key changes in the Medicare Advantage program.
The 2010 Affordable Care Act (ACA) included many provisions affecting the Medicare program and the 57 million seniors and people with disabilities who rely on Medicare for their health insurance coverage.

As Republican policymakers consider how to repeal and replace the Affordable Care Act (ACA), they are likely to face a number of decisions about whether to retain any of the law’s changes to Medicare. Repealing the ACA has potential implications for Medicare spending, beneficiaries, and other stakeholders, according to a new Kaiser Family Foundation brief.
A small share of Medicare Advantage enrollees switch plans each year, but those who do tend to pick plans with lower premiums and out-of-pocket limits than the plans they left behind, according to a new analysis by the Kaiser Family Foundation.
The Medicare open enrollment period allows enrollees to compare plans, stick with their current plan, switch to another plan, or shift to traditional Medicare. This analysis examines the extent to which Medicare Advantage enrollees change plans when given the opportunity. It also analyzes the variation in the rate of plan switching by enrollee and plan characteristics and whether people who voluntarily switch plans tend to move to plans with lower premiums, lower out-of-pocket limits, or higher quality ratings.
This chartpack presents a summary of Part D enrollment, premiums, cost sharing, benefit design and other key trends in 2016 and changes over time. For 2016, the analysis finds that 40% of Part D enrollees are now in Medicare Advantage drug plans, and over half of all enrollees are in plans offered by just three firms. The chartpack also highlights some concerning trends in the Low-Income Subsidy market, with the fewest number of premium-free plans available since Part D started, and 1.5 million LIS enrollees paying premiums for coverage, even though they have premium-free options available.
A Kaiser Family Foundation analysis of private Medicare plan networks finds that Medicare Advantage plans include about half of area hospitals in their network, on average, while one in five plans have no Academic Medical Center in-network.
This report takes an in-depth look at Medicare Advantage plans’ hospital networks. The analysis draws upon data from 409 Medicare Advantage plans serving beneficiaries in 20 diverse counties that together accounted for about one in seven (14%) Medicare Advantage enrollees nationwide in 2015. The report examines the size and composition of plans’ hospital networks, the variation across counties, the inclusion of Academic Medical Centers and NCI-Designated Cancer Centers, and the relationship between network size and other plan features, including premiums, quality star ratings, per capita Medicare spending, parent organization, and plan tax status.
