Texas sues Epic for allegedly ‘gatekeeping’ children’s medical records
By Chad Van Alstin | December 11, 2025

The state of Texas is suing Epic Systems, alleging that the electronic health record (EHR) giant is a monopoly, and that it’s made it intentionally difficult for patients and parents to access their medical records.

In an antitrust lawsuit filed on Dec. 10 by Texas Attorney General Ken Paxton, the maker of MyChart was accused of “gatekeeping” patient records, locking them up to deliberately prevent free access. For this particular complaint, filed in state court, Paxton is largely focused on challenges parents are allegedly having with controlling the medical records of their children.

His office said the problem comes down to a lack of competition, writing that Epic’s databases house “more than 325 million patient records, representing 90% of all U.S. citizens.”

“The corporation uses a wide range of exclusionary tactics to prevent potential competition from its partners, customers, and even its own employees,” Paxton’s office wrote in a statement. “Epic also interferes with hospitals’ ability to use its own patient data as part of its scheme to block software competitors.”

They go on to add that limited data sharing and access has deleterious effects on public health, because physicians are forced to make patient care decisions with “incomplete or out-of-date patient health records.”

Other accusations levied against Epic include that its business practices raise healthcare costs. Paxton said the company is in violation of state law, putting particular emphasis on parental rights codified in Texas Health & Safety Code § 183.006, which grants parents full access to the medical records of their minor children.

The attorney general said that by hiding “children’s medication lists, treatment notes and provider messages from parents,” Epic is infringing on the fundamental right of all parents to be involved in the medical decisions of children.

“We will not allow woke corporations to undermine the sacred rights of parents to protect and oversee their kids’ medical well-being,” Paxton stated. “This lawsuit aims to ensure that Texans can readily obtain access to these records and benefit from the lower costs and innovation that come from a truly competitive electronic health records market.”

More than 42% of all hospitals nationwide use Epic, making it the largest EHR vendor in terms of market share.

Epic denies controlling data on juveniles

In a statement, the company said plainly that it “does not determine parental access to children’s medical records."

"The action taken by Texas is flawed and misguided by its failure to understand both Epic’s business model and position in the market and the enormous contributions our company has made to our nation's healthcare system illustrated by products like MyChart—software that tens of millions of Americans depend on every day,” a spokesperson added.

"Every month, we improve quality of care by helping providers see a more comprehensive picture of their patient through over 725 million record exchanges—more than any other electronic health records vendor—and over half of these are with non-Epic systems," they stated. "Health systems using Epic shared information with almost 1,000 patient-facing apps 2 billion times in the past year."

The newly filed lawsuit is unlikely to gain traction until at least mid-2026 and is in its preliminary stages. A judge has not even ruled on if the case can move forward.
