Each year, Medicare beneficiaries have an opportunity to make changes to how they receive their Medicare coverage during the nearly 8-week annual open enrollment period. This brief answers key questions about the Medicare open enrollment period and Medicare coverage options.
The annual blitz of ads for Medicare Advantage plans has become a rite of fall, as health insurers, brokers and other third parties seek to court enrollees for these private plans, which are offered to the 65 million people with Medicare during the program’s open enrollment season.
Congress asked the U.S Department of Health and Human Services (HHS) Office of the Inspector General (OIG) to investigate whether Medicaid MCOs are providing medically necessary health care services to their enrollees. OIG found that Medicaid MCOs had an overall prior authorization denial rate of 12.5%–more than 2 times higher than the Medicare Advantage rate. Prior authorization denial rates ranged widely across and within parent firms and states. After a prior authorization request is denied, Medicaid enrollees can appeal, but it’s not always straightforward and many appeals don’t change the initial decision. Unlike in Medicare Advantage, if a Medicaid MCO upholds its original denial, there is no automatic, independent external medical review. OIG found that state Medicaid agency oversight of prior authorization denials is limited. The OIG report underscores concerns about prior authorization and access in Medicaid managed care, keeping this issue at the forefront of ongoing policy discussions.
Medicare Part D prescription drug coverage is available for people with Medicare who enroll in private plans, either a stand-alone prescription drug plan (PDP) for people in traditional Medicare, or a Medicare Advantage plan that covers all Medicare benefits, including prescription drugs (MA-PD). This issue brief provides an overview of Part D plan availability and premiums in 2024 and key trends over time.
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.
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.
