This page reports a data breach notice. Premise Health has not been found liable for anything, OCA has not identified a lawsuit over the breach, no class has been certified, and there is nothing to claim. This page is informational and is not legal advice.

What Is This About?

Premise Health Holding Corp. is notifying people that one of its own employees took their personal and health information. Letters are dated November 6, 2026, and a sample was filed with the California Attorney General.

According to the notice, Premise Health discovered on September 18, 2026 that an employee had violated company information security policies and misappropriated company data beginning on or about March 26, 2026. It revoked the employee’s access, validated its security controls and investigated, receiving a preliminary analysis of the data on October 14, 2026. The employee has been fired and the incident reported to law enforcement. Premise Health says it is not aware of any misuse of the information and has not published how many people were notified.

What Information Was Involved?

The notice says the information included, in part or whole, the person’s name, address, date of birth, a government identification number such as a Social Security number, health insurance information, diagnostic or other treatment information, and other information provided in connection with eligibility for services or the person’s relationship with Premise Health.

Some letters went to parents on behalf of minor dependents, and the monitoring offer includes a separate enrollment path for children.

An Insider, Not an Outside Hacker

Most breach notices describe an outside attacker. This one describes an employee who took data, starting about six months before the company says it found out. The notice does not say what the employee did with the data, how it was discovered or why the activity went undetected from March to September. Some law firm announcements about the incident describe outside “cybercriminals,” which does not match Premise Health’s own account.

What Premise Health Is Offering

Premise Health is offering a complimentary Experian IdentityWorks membership, with the length stated in each letter, plus Experian identity restoration help that does not require enrollment. Adults and minors enroll through separate Experian pages with the activation code in the letter, and codes stop working after 11:59 p.m. UTC on February 26, 2027.

Federal law also gives anyone notified of a breach free fraud alerts and security freezes through the three national credit bureaus; the Federal Trade Commission’s IdentityTheft.gov site explains how they work.

Has a Lawsuit Been Filed?

As of November 15, 2026, OCA had not identified a filed class action over the Premise Health breach, though several law firms have announced they are looking into it. Insider-theft cases raise different questions from hacking cases, including what access controls and monitoring the company had in place. Any such claims would be allegations. OCA will update this page if a complaint is filed or Premise Health reports how many people were affected.
