15 million people could lose Medicaid in the next year. Here's what the research says
Researchers estimate 15 million people will lose their Medicaid starting April 1 when states begin removing people from the low-income health insurance program for the first time in three years.
In March 2020, Congress banned states from removing people from Medicaid during the pandemic in exchange for more federal funding for state Medicaid programs. Medicaid enrollment is usually tied to people’s incomes, and individuals normally have to regularly prove they still qualify in what’s known as a redetermination. (In the 39 states and Washington, D.C., that have expanded Medicaid, a family of four has to make less than $40,000 to qualify. In non-expansion states, the cutoff is even lower.)
With redeterminations paused, Medicaid enrollment nationwide has grown from 71 million in February 2020 to an estimated 95 million in March 2023. Research shows Medicaid coverage is associated with better access to care, more financial security, better health and lower mortality. During the pandemic, beneficiaries have been able to enjoy these benefits without worrying about confirming their eligibility.
In December, Congress voted to let states restart the process of clearing their rolls on April 1, what’s sometimes referred to as “unwinding.” Lawmakers are giving states 14 months to redetermine millions of people’s eligibility — an unprecedented task made even more difficult by serious staffing and experience shortages in many Medicaid offices.
“It’s going to be a big lift,” said Sayeh Nikpay, a health policy researcher at the University of Minnesota and Tradeoffs Senior Research Advisor. “States have never had to do this many redeterminations this quickly before, and there’s a lot of uncertainty about what will happen.”
We asked Nikpay to pick out a few relevant studies to help us understand what is happening and how states and employers could keep more people insured. Here are three she identified as particularly helpful.
Two types of people will lose coverage
The Office of the Assistant Secretary for Planning and Evaluation, which provides research for the U.S. Department of Health and Human Services, released a report in August 2022 that estimated 15 million people will lose Medicaid coverage as a result of the unwinding. (The estimate is similar to another analysis by the independent Urban Institute.)
ASPE breaks those 15 million people into two groups. In the first group are people who make too much money to qualify for Medicaid. ASPE estimates there are about 8 million people in that category, and they should be able to get insurance through work or the Obamacare exchanges.
In the second group are roughly 7 million people ASPE estimates are still eligible but will lose coverage because of what’s called “administrative churn.” This can happen if the Medicaid office can’t get in touch with someone to confirm their eligibility because they’ve moved or changed their phone number or if they’re unable to make an in-person appointment because of work or child care responsibilities. (The Urban Institute projects about 4 million people will be in this group.)
These two groups represent a key tension to the unwinding process: States want to shed people who make too much money, but officials also know eligible people often lose coverage during redeterminations, and that danger is heightened given the scale and speed of this process.
Making the switch from Medicaid to private insurance
This next paper looks at the first group: the roughly 8 million people expected to move from Medicaid to private coverage, and specifically the roughly 4 million who are expected to get coverage through the Obamacare exchanges. Adrianna McIntyre, an assistant professor of health policy at Harvard, wrote in JAMA Health Forum in October 2022 about the most effective ways to move people from Medicaid onto private Obamacare plans.
There’s limited data on this, but based on the few studies available, McIntyre found that only 3 to 5 percent of people who leave Medicaid end up getting an Obamacare plan. Many policymakers are relying on the Obamacare exchanges to provide a life preserver to millions of people losing Medicaid coverage, but the research cited by McIntyre shows getting people into these plans is not guaranteed and will take focused effort by states.
McIntyre’s review cites several randomized controlled trials where states tested different ways of increasing enrollment in Obamacare plans. These studies found simple reminders from the state – like physical letters, emails and phone calls help – boost sign-ups anywhere from 7 to 16 percent.
But what really seems to make a difference is reminders plus connecting people to someone who can get them signed up while they are on the phone. In one of those trials published in 2022, people in California who got a reminder email and a call connecting them to enrollment assistance were almost 50 percent more likely to sign up for a plan. Such extra effort is obviously costly, and it may not be a priority or financially feasible for some states.
McIntyre’s review did not include any research on what employers can do to help their workers transition from Medicaid to work-based coverage, but based on the studies McIntyre cited, Nikpay said she thinks it’s a good idea for employers to make sure people know Medicaid could be going away and provide as much help as possible in getting new coverage.
Making it easier to stay on Medicaid can have other benefits
The final study looks at the second group of people expected to lose Medicaid coverage: the 7 million people who may lose coverage due to administrative churn even though they are still eligible.
Some states have tried to limit that churn, and researchers at the RAND Corporation evaluated New York’s effort. Starting in 2014, New York allowed people to stay on Medicaid without any redeterminations for 12 months once enrolled.
In addition to keeping more people on Medicaid for longer, researchers found that after this policy was in place, hospital admissions and monthly costs per beneficiary went down. The researchers can’t say whether the continuous enrollment policy directly caused these improved outcomes, but the findings suggest that avoiding administrative churn can help people stay covered without ballooning costs.
“It seems reasonable to me,” Nikpay said of the findings, “that making it easier to stay on Medicaid, even outside of a global pandemic, could benefit people’s health given what we know about how Medicaid affects people.”
