This brief reviews what we know about Medicaid enrollment changes during economic downturns, examines unemployment-linked Medicaid enrollments early on in the COVID-19 pandemic, and considers the implications for the unwinding of the national public health emergency (PHE).
In this issue brief, we estimate rates of Medicaid coverage loss among people who became Medicare-Medicaid enrollees (MMEs) during 2018 but did not have any months of MME coverage in the prior year. We compare outcomes for partial-benefit MMEs and full-benefit MMEs.
For 2023, the average Medicare beneficiary has access to 43 Medicare Advantage plans and can choose from plans offered by nine firms. Among the majority of Medicare Advantage plans that cover prescription drugs, 66 percent will charge no premium in addition to the monthly Medicare Part B premium. As in previous years, the vast majority of Medicare Advantage plans will offer supplemental benefits, including fitness, dental, vision, and hearing benefits. In addition, virtually all will also offer telehealth benefits in 2023.
This issue brief provides an overview of Medicaid spending and enrollment growth with a focus on state fiscal years 2022 and 2023. Findings are based on data provided by state Medicaid directors as part of the 22nd annual survey of Medicaid directors in states and the District of Columbia conducted by KFF and Health Management Associates (HMA). Findings examine changes in overall enrollment and spending growth.
This survey of Marketplace assister programs and brokers tracks the experiences of professionals signing people up for Affordable Care Act coverage. It also examines the role that these programs expect to play when the COVID-19 public health emergency (PHE) ends, potentially ending Medicaid eligibility for millions of Medicaid enrollees.
On August 31, the Centers for Medicare and Medicaid released a proposed rule to create more uniform processes across states that will make it easier for eligible people to obtain and maintain coverage in Medicaid and the Children’s Health Insurance Program (CHIP).
As Medicare Advantage continues to grow, a gradual but significant reshaping of the Medicare program is taking place. A new KFF analysis finds that nearly half of eligible Medicare beneficiaries – 28.4 million out of 58.6 million Medicare beneficiaries overall – are now enrolled in Medicare Advantage plans.
This brief examines typical enrollment patterns for Medicaid and CHIP and uses 2018 Medicaid claims data to gain insight into the effects of the continuous enrollment requirements by eligibility group. Roughly 2% of Medicaid enrollees come on or leave the program in an average month, although there is variation across eligibility groups. A policy to require continuous enrollment would result in sharp reductions in monthly disenrollment rates and would also reduce monthly enrollment rates due to reductions in churn.
A new KFF interactive provides essential facts and trends about spending on Medicare, the federal health insurance program that covers 65 million seniors and people with disabilities, or nearly 1 in 5 Americans. In 2020, Medicare spending accounted for 12 percent of the federal budget and 20 percent of national health care spending.
