With Medicare Part D nearing the end of its tenth year, the program -- which now provides drug coverage to 72 percent of all Medicare beneficiaries -- has experienced no growth in average premiums in recent years but some notable increases in cost-sharing, according to a new report from the Kaiser Family Foundation.
Despite initial controversy and uncertainties, Medicare Part D now provides drug coverage to thirty-nine million beneficiaries through dozens of private plans in each region. Although firmly established, the program faces challenges, including projected spending growth. Enrollees also face challenges as plans adopt new strategies to control costs.
This analysis focuses on out-of-pocket drug costs for Medicare Part D enrollees in 2016 for specialty, brand, and generic drugs. Part D drug plans differ considerably in the drugs they list on their formularies, their use of formulary tiers, and the level and structure of cost sharing applied to those tiers. Plan decisions affect different beneficiaries in different ways, depending on the drugs they use. The financial consequences for Part D plan enrollees can be substantial. In addition to examining costs for common drugs, we also examine profiles of multiple drugs for several hypothetical Part D enrollees.
Enrollment in Medicare Advantage continues to climb steadily as spending reductions enacted in the Affordable Care Act reduce historical overpayments to the private plans, according to a new analysis by the Kaiser Family Foundation. But limits on out-of-pocket spending for Medicare-covered services are rising, providing less protection for enrollees with relatively high health care expenses.
This Data Spotlight reviews national and state-level enrollment trends as of March 2015 and examines variation in enrollment by plan type and firm. It analyzes the most recent data on premiums, out-of-pocket limits, Part D cost-sharing for drugs, and plans’ quality ratings for Medicare Advantage enrollees.
When asked about a series of health care priorities facing President Trump and Congress, six in 10 Americans (60%) identify lowering the cost of prescription drugs as a “top priority” for President Trump and Congress – including majorities of Democrats, independents, and Republicans.
Medicare is likely to be back on the federal policy agenda this year as Congress and President Trump pursue repealing and replacing the Affordable Care Act, and potentially consider options to reduce federal spending.
As policymakers in Washington scrutinize the rising cost of the EpiPen auto-injector, a new analysis from the Kaiser Family Foundation shows that Medicare Part D spending for the potentially life-saving device increased by more than 1000 percent between 2007, the year after the Part D drug benefit took effect, and 2014, the most recent year…
The Medicare Part D program provides an outpatient prescription drug benefit to older adults and people with long-term disabilities in Medicare who enroll in private plans. This analysis provides the latest data about Medicare Part D coverage and costs in 2019 and trends over time, including enrollment, premiums, cost sharing, and participation in the low-income subsidy program.
The analysis examines enrollment in Medicare Advantage plans during beneficiaries’ first year on Medicare and finds that less than one-third or 29% enrolled in these private health plans, including HMOs or PPOs. The majority of people new to Medicare are choosing traditional Medicare in the year they first go on Medicare. The study looks at how these findings vary across age, Medicaid status, states, and counties.
