On March 26, 2026, the U.S. Department of Justice filed a major antitrust lawsuit against NewYork-Presbyterian, the largest hospital system in New York City, alleging that it uses illegal “all-or-nothing” contract provisions to force insurers and employers into including all of its eight hospitals in nearly every insurance network tier—or being excluded entirely. The lawsuit, filed in U.S. District Court for the Southern District of New York, charges the hospital system with violating Section 1 of the Sherman Act.
In practical terms, this means NewYork-Presbyterian prevents insurance companies from offering lower-cost plans that exclude the hospital system, blocking patients from accessing more affordable health coverage options that might feature competing hospitals instead. This case marks the second major hospital antitrust enforcement action the DOJ’s Antitrust Division has brought in 2026, following a similar lawsuit against OhioHealth Corporation in February. The NewYork-Presbyterian action is significant because it targets one of the most dominant healthcare providers in the nation’s largest metropolitan area, where hospital consolidation and pricing power have become increasingly controversial. The lawsuit seeks a court injunction to prohibit NewYork-Presbyterian from continuing these restrictive contracting practices. This article explains what the DOJ alleges, how these “all-or-nothing” contracts work to increase insurance costs for employers and patients, why the government believes they’re illegal, what remedies the DOJ is seeking, and what this case means for hospital consolidation and healthcare competition.

What Are the Specific Allegations Against NewYork-Presbyterian?
The DOJ’s complaint centers on newYork-Presbyterian’s contract terms that force an artificial choice on insurers: either include the entire hospital system—all eight facilities and associated outpatient centers—in your insurance networks at favorable rates and terms, or include none of them. According to the lawsuit, NewYork-Presbyterian prohibits insurers from offering plans that exclude any of its hospitals, prevents insurers from offering plans that don’t feature NewYork-Presbyterian in the most preferred tier (where patients pay the lowest copays), and blocks insurers from offering lower copays for patients who choose to use competing hospitals instead. The practical effect is stark: an insurance company that might otherwise create a lean, cost-competitive network built around less expensive competing hospitals cannot do so if it wants to include NewYork-Presbyterian, which is often essential for network adequacy in the New York City market. For example, an insurer might want to build a high-deductible health plan that encourages patients to use more cost-effective regional hospitals, but if patients need access to NewYork-Presbyterian for specialized services, the insurer is forced to include the full system at rates and terms NewYork-Presbyterian dictates.
This eliminates the insurer’s ability to create meaningful price differentiation or network tiers, which in turn limits the health insurance options available to employers and individual consumers. NewYork-Presbyterian, as the largest and most powerful hospital system in the city with eight hospitals and extensive outpatient facilities, has the market use to enforce these take-it-or-leave-it terms. Insurers face enormous pressure to comply because excluding NewYork-Presbyterian from networks could make their plans unattractive or medically inadequate in the New York City market. The hospital system’s response to the lawsuit is that it believes the case is without merit—but the DOJ is arguing that the contract restrictions themselves are inherently anticompetitive and illegal regardless of intent.
How Do These Contracts Harm Consumers and Employers?
The harm flows in two directions. First, employers and insurance companies lose the ability to negotiate and structure networks strategically around price and efficiency. Normally, insurers compete by building different network types: exclusive provider organizations (EPOs) with narrow networks of cost-effective hospitals, preferred provider organizations (PPOs) with broader options, and other variants that give employers and individuals a choice of coverage models at different price points. NewYork-Presbyterian’s all-or-nothing contracts prevent this. An insurer cannot create an EPO or narrow-network plan that cuts costs by excluding less essential hospitals while keeping NewYork-Presbyterian, because the contract forbids it. Second, and most importantly for patients, this limits the health plan options available.
If NewYork-Presbyterian contracts eliminate the insurer’s ability to offer cheaper, narrower-network plans, then employees and individuals are forced into more expensive broad-network plans, or those plans must pass the added cost of including NewYork-Presbyterian’s premium pricing onto subscribers through higher premiums, copays, and deductibles. A hospital system with dominant market position that forces its inclusion in all tiers essentially guarantees that its high fees get baked into the health insurance products everyone can access, because no insurer can profitably exclude it or tier it differently. However, there is one important limitation to understand: the DOJ’s lawsuit does not necessarily mean NewYork-Presbyterian has done anything wrong by negotiating aggressively or by being expensive. Hospitals have a right to negotiate the terms of their contracts with insurers. What the lawsuit alleges is illegal is the *contract structure itself*—the provision that one party’s willingness to contract requires including 100% of the system in all tiers, with no alternatives. The distinction matters: a hospital can charge high prices (that is capitalism and negotiation), but it allegedly cannot use contract terms that strip an insurer of the option to shop around or structure a network differently. If NewYork-Presbyterian had simply negotiated high rates while allowing insurers the contractual freedom to tier the hospitals or exclude them, the same pricing power might exist without the antitrust violation.
Why Is the DOJ Calling This a Violation of the Sherman Act?
The Sherman Act’s Section 1 prohibits “contracts, combinations, or conspiracies in restraint of trade.” The DOJ argues that the all-or-nothing contract provisions are per se illegal—meaning they are inherently anticompetitive on their face—or at minimum that they violate the Sherman Act under a rule-of-reason analysis (balancing competitive harm against any procompetitive justification). The theory is that the contract clauses directly restrain an insurer’s ability to offer alternative products and prevent the insurer from using its buying power to negotiate with NewYork-Presbyterian’s competitors for lower rates. Antitrust law has long been skeptical of “tied” arrangements and bundling provisions in contracts, especially when imposed by dominant firms. The classic example is a company that says “you can buy our product X only if you also buy our product Y,” which eliminates a customer’s choice to purchase product Y from a competitor.
NewYork-Presbyterian’s contracts operate similarly: they say “you can include our hospitals in your plan only if you include all of them in all tiers”—effectively tying the inclusion of lesser-used facilities to the inclusion of essential ones, and eliminating the insurer’s option to include some NewYork-Presbyterian hospitals while creating a lower-cost option through competing facilities. The DOJ likely will argue that this conduct fits the pattern of anticompetitive behavior by hospital systems that the government has increasingly challenged. Health insurance markets in concentrated areas depend on competitive negotiations between insurers and hospital systems. When a dominant hospital system uses contract terms to eliminate an insurer’s negotiating options (like the option to create competing network tiers), it potentially reduces competition, limits consumer choice, and props up prices. The government alleges this is exactly what NewYork-Presbyterian’s contracts do.
What Is the DOJ Seeking as a Remedy?
The Justice Department is seeking a civil injunction to prohibit NewYork-Presbyterian from imposing these contractual restrictions. An injunction would order the hospital system to remove the all-or-nothing contract clauses, allowing insurers to negotiate more flexible terms: they could include some NewYork-Presbyterian hospitals while excluding others, they could include the system’s facilities in preferred tiers while offering lower-cost alternatives through competitors, or they could structure networks without NewYork-Presbyterian’s artificial constraints. The injunction would not prevent NewYork-Presbyterian from negotiating high rates—it would simply require that the hospital system negotiate on the *merits* of individual facilities and services, rather than using contract language to force bulk inclusion.
Competing hospitals could then offer their services on competitive terms, insurers could build networks that reflect actual patient needs and cost-effectiveness, and patients and employers would gain access to a wider range of insurance products at different price points. The tradeoff here is important: an injunction would give NewYork-Presbyterian less use in contract negotiations, but it would restore competitive negotiation on both sides of the table. The hospital system would still be free to command high prices for highly valued services and facilities—but it would have to justify those prices based on quality and demand, not force them through take-it-or-leave-it contract provisions. For employers and individual consumers, the benefit is choice: plans could be built that include NewYork-Presbyterian’s tertiary care centers while directing routine care to more cost-effective facilities, giving patients the best of both worlds.
Why Is This the Second Hospital Antitrust Case in 2026?
The NewYork-Presbyterian lawsuit follows the DOJ Antitrust Division’s filing against OhioHealth Corporation in February 2026, marking an escalation in federal scrutiny of hospital consolidation and antitrust conduct. OhioHealth is a 16-hospital nonprofit system, making it one of Ohio’s largest healthcare providers. The parallel timing and focus on both cases—dominant regional hospital systems using market power in contract negotiations—suggests the DOJ is executing a coordinated enforcement strategy against hospital systems that use their scale to eliminate insurer choice. This strategy reflects years of building evidence about how hospital consolidation has driven up healthcare costs.
When dominant hospital systems in major metropolitan areas can force all-or-nothing contracting, they eliminate the competitive pressure that normally encourages healthcare providers to improve efficiency and moderate pricing. The government is signaling that it will challenge these practices at leading systems, not just small regional actors. A critical limitation, however: the DOJ’s ability to win these cases depends on court agreement that the contract provisions are anticompetitive. Hospitals will argue that these clauses are justified by legitimate business reasons—coordinating care quality, maintaining contractual simplicity, protecting network adequacy—and it is not certain that courts will find the government’s antitrust theory persuasive, especially in the current judicial environment where some judges are skeptical of expansive antitrust enforcement.
What Does This Mean for Hospital Consolidation and Healthcare Markets?
The NewYork-Presbyterian case signals that the Biden-Harris administration’s DOJ Antitrust Division is willing to challenge dominant hospital systems and will focus on contractual provisions and negotiating practices, not just on blocking mergers. This creates potential use: hospital systems and insurers considering similar all-or-nothing or bundling provisions may now hesitate, knowing that such practices are being litigated and could be found illegal.
However, the case also highlights a deeper problem in healthcare: intense consolidation in many metropolitan areas has given dominant hospital systems enormous use. NewYork-Presbyterian’s ability to impose these contract terms reflects not just bad faith, but also genuine market dominance—the system is so important for network adequacy that insurers have limited practical alternatives. Even if the DOJ wins the NewYork-Presbyterian case, it may not fully solve the underlying issue unless it is coupled with antitrust scrutiny of existing hospital mergers, FTC challenges to future consolidation, or other structural remedies that restore competitive pressure in local healthcare markets.
What Happens Next in the Lawsuit and Hospital Antitrust Enforcement?
The case is now in the federal district court for the Southern District of New York, where it will proceed through the normal litigation process: discovery, possible motions to dismiss, and trial if the parties do not settle. Hospital systems and insurers are closely watching the outcome, as it could reshape contract negotiation practices across the industry. If the DOJ wins, expect insurers to aggressively renegotiate existing contracts to remove all-or-nothing clauses, and expect new hospital contracts to include provisions allowing network flexibility.
Looking forward, the DOJ has signaled that hospital antitrust enforcement will remain a priority. The combination of the OhioHealth case filed in February and the NewYork-Presbyterian case filed in March 2026 suggests the government is in active investigation mode, likely examining other dominant regional hospital systems for similar conduct. For healthcare markets, the stakes are high: if the government succeeds in constraining hospital market power through antitrust litigation, patients and employers may gain access to more competitive health insurance options and more efficient healthcare networks. If the hospitals prevail, market consolidation will likely continue unchecked, and the all-or-nothing contracting approach may become an industry standard.
