PORTLAND, Maine — A network of clinics that provides health care in Maine is expected to ask a judge Thursday to restore its Medicaid funding while it fights a Trump administration effort to keep federal money from going to abortion providers.

President Donald Trump’s policy and tax bill, known as the “ big beautiful bill,” blocked Medicaid money from flowing to Planned Parenthood, the nation’s largest abortion provider. The parameters in the bill also stopped funding from reaching Maine Family Planning, a much smaller provider that provides health care services in one of the poorest and most rural states in the Northeast.

Maine Family Planning filed a federal lawsuit last month seeking to restore reimbursements.

Lawyers and representatives for Maine Family Planning say its 18 clinics provide vital services across the state including cervical cancer screenings, contraception and primary care to low-income residents. They also say the funding cut occurred even though Medicaid dollars are not used for its abortion services.

“Without Medicaid, MFP will be forced to stop providing all primary care for all patients — regardless of their insurance status — by the end of October,” the organization said in a statement, adding that about 8,000 patients receive family planning and primary care from the network.

It also said many Maine Family Planning clinics “provide care in very rural areas of the state where there are no other health care providers, and around 70% of their patients rely exclusively on MFP and will not see any other health care provider in a given year.”

In court documents, Anne Marie Costello, deputy director for the Center for Medicaid & CHIP Services, called the request to restore funding “legally groundless” and said it “must be firmly rejected.”

“The core of its claim asks this Court to revive an invented constitutional right to abortion — jurisprudence that the Supreme Court decisively interred — and to do so in a dispute over federal funds,” Costello said.

While advocates of cutting Medicaid for abortion providers focused on Planned Parenthood, the bill did not mention it by name. Instead it cut off reimbursements for organizations that are primarily engaged in family planning services — which generally include things such as contraception, abortion and pregnancy tests — and received more than $800,000 from Medicaid in 2023.

The U.S. Senate’s parliamentarian rejected a 2017 effort to defund Planned Parenthood because it was written to exclude all other providers by barring payments only to groups that received more than $350 million a year in Medicaid funds. Maine Family Planning asserts in its legal challenge that the threshold was lowered to $800,000 this time around to make sure Planned Parenthood would not be the only entity affected.

It is the only other organization that has come forward publicly to say its funding is at risk.

BOSTON — Attorneys for Planned Parenthood clinics nationwide argued in federal court Friday that cutting off Medicaid funding to its abortion providers would hurt vulnerable patients who already have limited health care options.

Planned Parenthood Federation of America and its affiliates in Massachusetts and Utah are fighting to block part of President Donald Trump’s tax bill they say is designed to target their clinics. The provision would end Medicaid payments to abortion providers like Planned Parenthood that primarily offer family planning services — things like contraception, abortion and pregnancy tests — and received more than $800,000 from Medicaid in 2023.

Although Planned Parenthood is not specifically named in the statute, which went into effect July 4, the organization’s leaders say it was meant to affect their nearly 600 centers in 48 states. However, a major medical provider in Maine and likely others have also been hit.

“It’s the affiliation provision that makes this rotten to the core,” said Planned Parenthood attorney Alan Schoenfeld during Friday’s hearing in Boston.

The plaintiffs have filed their federal lawsuit against Health and Human Services Secretary Robert F. Kennedy Jr.

So far, the provision has been on hold after U.S. District Judge Indira Talwani in Boston granted a temporary restraining order blocking the cuts for two weeks. That order expires July 21, when Talwani has said she will decide whether to grant a motion for a preliminary injunction against the funding cuts while the lawsuit plays out.

On Friday, Talwani was particularly focused on getting a definition of what constituted an affiliation and what a Planned Parenthood health center would have to do to qualify for Medicaid funding, quizzing the federal government’s attorneys if stopping abortions would be enough or if they would have to completely severe all ties.

Emily Hall, an attorney representing HHS, said Friday that the federal government needs more information about Planned Parenthood’s structure and time to finalize interpretations of the law.

“It depends on the nature of the corporate relationship, which I don’t have,” Hall said.

Fears of pending cuts to Planned Parenthood further escalated this week after a Planned Parenthood office in Ohio announced Tuesday that it was closing two health clinics — in Hamilton and Springfield, north of Cincinnati — due to state and federal cuts.

“Make no mistake: This is not a decision made by Planned Parenthood of Southwest Ohio Region,” President and CEO Nan Whaley, a one-time Democratic gubernatorial nominee, told reporters. “We took every possible step to keep these centers open, but the devastating impact of state and federal political attacks has forced us into this very difficult position.”

The centers provide preventive health care, including testing for sexually transmitted diseases, birth control and wellness exams.

Medicaid is a government health care program that serves millions of low-income and disabled Americans. Nearly half of Planned Parenthood’s patients rely on Medicaid.
