This Policy Insight draws on the experiences of Medicare beneficiaries during Medicare’s annual enrollment period to consider whether consumers with health insurance coverage through the Affordable Care Act’s new marketplaces will shop for a better deal during their open enrollment season.
With Medicare's 2015 open enrollment set to begin Oct. 15, two new analyses from the Kaiser Family Foundation find modest change in the total number of private Medicare Advantage plans available for 2015, and the fewest Part D prescription drug plans nationwide since the start of the drug benefit in 2006. As in previous years, changes in Medicare Advantage and Part D plan availability, premiums, cost-sharing and benefits could require some beneficiaries to find alternative coverage and lead others to pay more if they continue with their existing coverage.
This Data Note examines the availability of plans nationwide and by state in 2015, and changes in plan availability since 2011. It documents the number and share of Medicare Advantage enrollees affected by plan withdrawals each year, the characteristics of plans that will be entering the market and characteristics of those exiting the market in 2015.
This slideshow explains key elements of the Medicare program, which now provides health coverage to 55 million people — including 46 million people age 65 and older and another 9 million younger adults with permanent disabilities.
The House-passed legislation to repeal the Medicare Sustainable Growth Rate (SGR) includes a provision that would prohibit Medicare supplemental insurance (Medigap) policies from covering the Part B deductible for people who become eligible for Medicare beginning in 2020.
This report examines the Center for Medicare and Medicaid Services (CMS) financial alignment demonstration for beneficiaries dually eligible for Medicare and Medicaid, with a focus on the extent to which participating states and health plans have prior experience with capitated managed care arrangements under Medicare or Medicaid, and specifically for this population. Under these capitated financial alignment demonstrations, health plans contract with the state and CMS (a three-way contract) to provide both Medicare and Medicaid benefits to dually eligible beneficiaries. These demonstrations aim to improve the quality of care and the coordination of benefits for people dually eligible for Medicare and Medicaid. The report finds considerable variation in the experience of states and health plans participating in these demonstrations, and discusses the potential implications for beneficiaries and plan oversight.
On March 26, 2015, the House of Representatives passed H.R. 2, the Medicare Access and CHIP Reauthorization Act of 2015, which would replace the Sustainable Growth Rate (SGR) formula, among other changes; the bill is currently pending in the U.S. Senate. H.R. 2 includes a provision that would prohibit Medicare supplemental insurance (Medigap) policies from covering the Part B deductible for people who become eligible for Medicare on or after January 1, 2020. This data note looks at the number and share of “new” Medicare beneficiaries who would be affected by the Medigap provision in H.R. 2, if it had been implemented in 2010, using the most current data sources available, and examines trends in Medigap enrollment among new beneficiaries since 2000.
This report examines similarities and differences in federal consumer protection standards for Medicare Advantage (MA) plans, Qualified Health Plans (QHPs), and Medicaid Managed Care Organizations (MCOs). It focuses on rules established at the federal level, though some states have chosen to go above the federal minimums and impose additional requirements for QHPs and Medicaid MCOs.
