Questions about this case?
AI Legal Assistant · free · answers in seconds · general information, not legal advice
A search for a UnitedHealthcare lawsuit turns up several unrelated cases against UnitedHealth Group and its units. The newest development: on September 30, 2026, a federal judge in Minnesota let part of an investor class action go forward and threw out most of it. The UnitedHealthcare class action most members ask about — over an AI tool allegedly used to cut off rehab and nursing-home coverage for Medicare Advantage patients — is in discovery, with trial readiness set for February 2028. As of September 30, 2026, none of the cases on this page has a settlement, a fund or a claim form.

The Cases, One by One
1. AI denials of post-acute care (nH Predict). A proposed class action filed November 14, 2023. The named plaintiffs bought UnitedHealthcare Medicare Advantage plans and were denied coverage for post-acute care — the rehab and skilled nursing that follows a serious illness or injury. The lawsuit alleges that the defendants — UnitedHealth Group, UnitedHealthcare and naviHealth, which the court calls “UHC” together — used an artificial-intelligence program, the nH Predict AI Model, in place of physicians to decide how much care to cover, and knew the tool was inaccurate because over 90% of claim denials are reversed on appeal. UHC denies any use of nH Predict, the court noted.
2. Investor class action. The California Public Employees' Retirement System (CalPERS), the lead plaintiff, alleges UnitedHealth misled shareholders between September 22, 2021 and July 28, 2025 about its Medicare Advantage business, Optum and a series of “portfolio refinement” asset sales. The complaint says the stock fell from around $600 to less than $300 per share as problems surfaced in 2024 and 2025.
3. Medicare Advantage billing. A whistleblower suit filed under seal in 2011 alleges improper risk-adjustment submissions in violation of the False Claims Act; the Justice Department decided in 2017 to pursue certain of its claims. Separately, UnitedHealth disclosed on July 24, 2025 that it had begun complying with formal criminal and civil requests from the Justice Department about its participation in the Medicare program.
4. Change Healthcare breach and OptumRx. Both have their own pages, so we do not repeat them here: the Change Healthcare data breach lawsuit (192.7 million people reported, MDL No. 3108) and the OptumRx lawsuit page for the pharmacy-benefit cases, including the insulin-pricing suit Florida announced on September 22, 2026.
Case Details
AI denials: Estate of Gene B. Lokken v. UnitedHealth Group, Inc., No. 0:23-cv-03514 (D. Minn.), before Judge John R. Tunheim, with Magistrate Judge Shannon G. Elkins handling scheduling. The defendants are UnitedHealth Group, UnitedHealthcare and naviHealth (docket).
Investors: California Public Employees' Retirement System v. UnitedHealth Group Inc., No. 0:24-cv-01743 (D. Minn.), before Judge Jeffrey M. Bryan, filed May 14, 2024, under Sections 10(b), 20(a) and 20A of the Securities Exchange Act (docket).
Medicare billing: United States ex rel. Poehling v. UnitedHealth Group, Inc., No. 2:16-cv-08697 (C.D. Cal.). The criminal and civil requests UnitedHealth disclosed in 2025 are investigations, not lawsuits (company filing).
Change Healthcare: MDL No. 3108 in the District of Minnesota, before Judge Donovan W. Frank.
Status on September 30, 2026: Nothing to Claim
AI-denial case — discovery. On September 18, 2026 the court reset the schedule: fact discovery closes April 26, 2027, dispositive motions are due September 27, 2027, and the case is to be ready for trial February 7, 2028. At an August 24, 2026 conference the parties were told to talk about settlement and report to the magistrate judge by September 30, 2026. What they reported is not public, and the docket shows no class-certification ruling.
Medicare billing — unresolved. In the False Claims Act case, a court-appointed special master recommended in March 2025 that the court enter summary judgment for UnitedHealth on all remaining claims; the Justice Department asked the court in April 2025 to reject that report. In its quarterly report filed August 10, 2026, UnitedHealth said it could not reasonably estimate the outcome given the case's procedural status.
Change Healthcare — pretrial. As of September 30, 2026, no class has been certified and no settlement has been announced in MDL No. 3108.

Who Could Be Affected
Medicare Advantage members denied rehab or skilled nursing. The AI-denial case was filed as a proposed class action by UnitedHealthcare Medicare Advantage members whose post-acute care was denied. No class has been certified, so there is nothing to join. If a class is certified or a settlement is reached, class members would be notified. Keep your denial letters, appeal decisions and any bills you paid yourself.
Shareholders. The proposed class period in the investor case runs from September 22, 2021 through July 28, 2025; if you bought UnitedHealth shares in that window, you may fall within the proposed class. After the September 30, 2026 ruling, only claims tied to five statements remain. You do not sign up; keep your brokerage statements.
Everyone else. The False Claims Act case and the Justice Department investigations are government matters. They have no class and no claim process for members. If you received a Change Healthcare breach letter, see the Change Healthcare page.
Is There Money? Not Yet
In the AI-denial case, the claims left after the February 13, 2025 ruling are contract claims: breach of contract and breach of the implied covenant of good faith and fair dealing. The insurance bad-faith and state consumer-protection claims were dismissed with prejudice. In the investor case, any recovery would be tied to shares bought during the class period and, after September 30, 2026, to the five remaining statements. A False Claims Act recovery is paid to the federal government, not to plan members.

Three Things to Watch For
Several unrelated cases under one brand name make it easy to blur them together:
“Claim your UnitedHealthcare AI-denial settlement”
There is no settlement in the nH Predict case. It is in discovery, with trial readiness set for February 2028. A site asking for your Medicare number or member ID to “reserve your payment” is collecting data, not filing anything.
Investor “deadline” ads about UNH stock
Law-firm ads about UnitedHealth shares often announce a deadline. That deadline is for asking to be lead plaintiff, and this court already has one: CalPERS. Members of a proposed shareholder class do not have to sign up to be included.
Calls about a “UnitedHealthcare refund”
A caller who knows your plan name can still be a scammer. Hang up and call the number on your member ID card. A real class notice comes from a court-appointed administrator and names the court and the case number.
UnitedHealthcare Lawsuit — Questions People Actually Ask
Is there a UnitedHealthcare class action settlement I can file a claim in?
No. As of September 30, 2026, none of the cases on this page — the AI-denial class action, the investor suit, the Medicare billing matters or the Change Healthcare breach — has a settlement, a fund or a claim form. For settlements that are open now, see our open class action settlements list.
What is the UnitedHealthcare AI lawsuit about?
Medicare Advantage members allege that UnitedHealthcare used the nH Predict AI Model instead of doctors' judgment to decide how much post-acute care to cover, cutting off rehab and skilled nursing. UnitedHealthcare denies any use of nH Predict. The case is No. 0:23-cv-03514 in federal court in Minnesota.
My rehab or nursing-home coverage was cut off. Can I join the UnitedHealthcare lawsuit?
There is nothing to sign. It is a proposed class action and no class has been certified. If a class is certified or a settlement is reached, members would be notified. If you want to pursue your own claim, talk to a licensed attorney, and keep every denial letter and appeal decision.
What did the judge decide in the UnitedHealth investor case on September 30, 2026?
Judge Jeffrey M. Bryan dismissed with prejudice the claims built on 43 of 48 challenged statements, including those about the alleged Medicare Advantage schemes and Optum's data firewalls. He let claims over five statements about the portfolio-refinement asset sales and April 2025 earnings guidance go forward, and dismissed the insider-trading count without prejudice.
I own UnitedHealth stock. Do I need to do anything?
Not now. The proposed class period runs from September 22, 2021 through July 28, 2025. No class has been certified and there is no settlement. Keep your brokerage records; if the case settles, a notice will explain how to claim.
Is UnitedHealth under DOJ investigation over Medicare Advantage?
On July 24, 2025, UnitedHealth disclosed that it had begun complying with formal criminal and civil requests from the Justice Department about its participation in the Medicare program. A separate False Claims Act case over risk-adjustment submissions dates to a whistleblower filing in 2011. We found no newer public update on the 2025 requests, and the company's August 10, 2026 quarterly report does not describe them or any outcome; on the False Claims Act case it says it cannot reasonably estimate the outcome given the case's procedural status.
Is the Change Healthcare breach a UnitedHealthcare lawsuit?
Change Healthcare is a UnitedHealth Group company, and the breach is litigated separately as MDL No. 3108 in Minnesota. As of September 30, 2026, it has no settlement and no claim form. See our Change Healthcare data breach lawsuit page.
What can I do right now if UnitedHealthcare denies my care?
Appeal, and keep going if the first answer is no. For a Medicare Advantage plan, a standard appeal starts with a written request for reconsideration to the plan, generally within 60 calendar days of the denial notice. If the plan is ending rehab or skilled nursing services, you can ask for a fast-track appeal to an independent review entity right away. The AI-denial lawsuit alleges that over 90% of claim denials are reversed on appeal; that is the plaintiffs' allegation, not a court finding.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
