When the head of the nation’s largest publicly operated health plan worries about the looming federal cuts to Medicaid, it’s not just her job. It’s personal.

Martha Santana-Chin, the daughter of Mexican immigrants, grew up on Medi-Cal, California’s version of Medicaid, the government-run health care program for people with low incomes and disabilities. Today, she is CEO of L.A. Care, which runs by far the biggest Medi-Cal health plan, with more than 2.2 million enrollees, exceeding the Medicaid and Children’s Health Insurance Program enrollments in 41 states.

“If it weren’t for safety nets like the Medi-Cal program, I think, many people would be stuck in poverty without an ability to get out,” she said. “For me personally, not having to worry about health care allowed me to really focus on what I needed to focus on, which was my education.”

As she begins her second year steering L.A. Care, Santana-Chin is grappling with federal and state spending cuts that complicate her task of providing health care to the poor and medically vulnerable enrollees in Medicaid. The insurer also provides Affordable Care Act marketplace plans through Covered California.

Santana-Chin warns that the GOP’s One Big Beautiful Bill Act, enacted last year and also known as HR 1, could result in 650,000 enrollees falling off L.A. Care’s Medi-Cal rolls by the end of 2028. This will strain the plan’s finances as revenues decline. The insurer had revenues of $11.7 billion in the last fiscal year.

HR 1 is expected to cut more than $900 billion from Medicaid over the next 10 years — including $30 billion or more in California, according to the Department of Health Care Services, which runs Medi-Cal.

Like other states facing big deficits, California has reduced its Medicaid spending through such steps as freezing new enrollments for immigrants without legal status and reintroducing an asset limit. And that’s before the state reckons with the spending cuts that likely will be required by the withdrawal of so many federal dollars under HR 1.

Santana-Chin oversaw Medi-Cal and Medicare operations for the for-profit insurer Health Net before taking the helm of L.A. Care in January 2025, nearly three years after state regulators fined L.A. Care $55 million over violations they said compromised the health and safety of its members. L.A. Care paid $27 million in penalties to the state and agreed to contribute $28 million to community health projects.

In a wide-ranging interview, Santana-Chin talked to KFF Health News senior correspondent Bernard J. Wolfson about the financial headwinds facing L.A. Care and why she believes health care shouldn’t be restricted based on a person’s immigration status. This interview has been edited for length and clarity.

Q: You grew up on Medicaid. How has that shaped your views now that you run one of the largest Medicaid plans in the country?

What really motivates me is knowing that many of the people that we’re serving are just like my family. They’ve struggled and have had to have their own children translate things that were very difficult to translate. I remember doing that for my own mother. You know, basic human dignity requires that you have access to health care.

Q: Has anything you’ve dealt with at Health Net or L.A. Care reminded you of your childhood experiences in Medi-Cal?

Back then they didn’t cover transportation, and we didn’t have a vehicle. Today, one of the issues we’ll hear from our members is the need to make sure we have trustworthy transportation that shows up on time, where the drivers treat them with respect. Had I had that, had my mother had that, life would have been much easier.

Q: What do you think the impact of HR 1 will be?

It’s going to devastate the delivery system. The state obviously isn’t going to be able to make up for the shortfalls in federal funding, and over the course of the next several years, funding is going to be less and less, and the people we cover are going to decrease significantly. We are expecting between now and the end of 2028 that we’re going to see 650,000 people drop off the rolls. That’s just L.A. Care.

Q: That’s over a quarter of your Medi-Cal enrollment.

Yes, it’s very, very significant. The reductions in payment and the rise in uncompensated care are really going to impact our delivery system. As the delivery system gets destabilized and hospitals and other health care providers are forced to close services or reduce the number of sites they have, it’s going to impact access. And it’s not only going to impact those that lose coverage.

Q: How will L.A. Care respond?

Obviously, we’re going to see a significant drop in revenue. We’re very focused on making sure that we are operating as efficiently as we can operate. And we are looking at creative ways to use technology to empower our people to do higher-level work. Mostly supporting our call center agents with smarter technology that helps them answer questions and resolve problems more quickly. Some of it is automating processes on the claims payment side.

Q: What do you have to say to congressional Republicans who passed HR 1?

We are at a point of inflection in the health care delivery system. And we have to recognize that some of the components of HR 1 will have long-term unintended consequences — maybe they were intended; I’ve got to believe that some of these things are not. There’s probably a need to reconsider some of the things that were passed.

Q: Such as?

Work requirements are an example of something that many people did believe was the right thing to do to be good stewards of the health care dollar. It is very complex and is going to cause people to lose coverage that actually do qualify. It’s unfortunate, and that would be something that I would urge folks to reconsider.

Q: What impact do you expect from California’s decision to freeze Medi-Cal enrollment for immigrants without legal status?

It doesn’t matter what immigration status you are. If you are a human being and you need health care, you’re going to try to access health care wherever you can. That’s going to put a strain on the delivery system if you’re uninsured.

Q: What has L.A. Care done to address the state’s concerns in 2022 that it delayed authorizing care and addressing patient grievances?

There has been quite a bit of investment in the L.A. Care infrastructure over the last several years — our IT platforms, our data. There’s also quite a bit of investment in adding new capacity, adding bandwidth to many of the teams, more folks to help support the work.

Q: How have federal immigration raids in L.A. affected L.A. Care members and the broader community?

It absolutely has had a chilling effect. Families are afraid to come in. They’re not taking their children to get vaccinated. I’ve had numerous providers in emergency departments say that they have experienced a drop in the volume of individuals coming in. One of our case managers was really distraught because there was an individual that decided to forgo serious lifesaving treatment because of fear.KFF Health News is a national newsroom that produces in-depth journalism about health issues and is one of the core operating programs at KFF—an independent source of health policy research, polling, and journalism.
