Nearly 3 million Medicare Part D enrollees had out-of-pocket drug spending above the catastrophic threshold in a recent five-year period, finds a new KFF analysis that takes a comprehensive look at how many people on Medicare have drug expenses high enough to push them above that limit.
In response to prescription drug spending growth and heightened attention to drug prices, some policymakers have proposed allowing the federal government to negotiate the price of prescription drugs for Medicare and private payers. This brief describes the current status of drug price negotiation proposals, looks back at the history of proposals to give the federal government the authority to negotiate drug prices in Medicare, describes the negotiation provisions in key legislation (H.R. 3), and discusses the potential spending effects for the federal government, beneficiaries, and private payers.
Medicare Part D, the outpatient prescription drug benefit for Medicare beneficiaries, provides catastrophic coverage for high out-of-pocket drug costs, but there is no limit on the total amount that beneficiaries have to pay out of pocket each year. Policymakers on both sides of the aisle support proposals to modify the design of the Part D benefit and establish a hard cap on out-of-pocket prescription drug spending by Part D enrollees. This analysis shows the number of Part D enrollees without low-income subsidies who have exceeded the catastrophic coverage threshold annually, and over multiple years, based on 2007-2019 Part D claims data.
The brief examines the potential impact of Aduhelm, a newly approved drug for Alzheimer's disease, on state and federal Medicaid costs and looks at potential policy actions that could limit Medicaid’s potential costs.
The Build Back Better Act (BBBA) includes a range of health and other proposals supported by President Biden, including a proposal to allow the federal government to negotiate the price of some prescription drugs covered under Medicare Part B (administered by physicians) and Medicare Part D (retail outpatient drugs). This brief illustrates the potential scope of the drug price negotiation proposal in the BBBA. This analysis is designed to highlight the types of Medicare-covered drugs that could be subject to negotiation, and which of the current top-spending drugs covered by Part B and Part D could be subject to price negotiation, and in what years, if the BBBA is enacted.
In a new Policy Watch, KFF experts explain why Medicare’s preliminary decision to cover a new Alzheimer’s drug only for a limited group of beneficiaries is likely to intensify pressure on officials to reconsider the increase in the Medicare Part B premium for 2022.
This policy watch discusses the implications of Medicare's preliminary National Coverage Determination for the new Alzheimer's drug, Aduhelm, on the 2022 Medicare Part B premium and the possibility of an adjustment based on the coverage decision. The piece also discusses the implications for Medicare spending and the connection to ongoing policy discussions around prescription drug proposals in the Build Back Better Act.
The $21.60 increase in 2022 is the largest in dollar terms since the start of the program, even though premiums have risen faster in percentage terms on three other occasions in the last 20 years
This data note describes Medicaid prescription drug utilization and spending trends in calendar year 2020 compared to previous years to explore how the pandemic impacted Medicaid prescription drug utilization and spending.
Provisions in the bill that would lower prescription drug costs and reduce federal drug spending would take effect over the next several years, starting in 2023.
