More than 760,000 people lost health insurance after the federal government canceled roughly 315,000 Marketplace enrollments it says were unauthorized. That does not mean 760,000 people committed fraud. Learn what happened, who may have been affected, and how to make sure the coverage in your name is the coverage you actually chose.
760,000 People Lost Health Insurance — Here’s What Happened
ACA Marketplace Cancellations: Why 760,000 People Lost Coverage and What to Check in Your Own Account
The headline number is huge. But the story behind it is more complicated than it first sounds.
Some of the people who lost coverage may have been victims themselves. They may have been signed up for a plan, switched into a different plan, or had their information changed by an insurance agent or broker without knowingly approving it.
For some people, the first sign could be a doctor suddenly being out of network, a prescription no longer being covered, or a tax form for insurance they did not realize they had.
What CMS Did
The cancellations took effect on August 31, 2026. The Centers for Medicare & Medicaid Services (CMS) announced the action on September 22.
The agency says about $2.2 billion in federal premium tax credits tied to those policies is expected to be returned or recovered.
The affected coverage was sold through the Affordable Care Act Marketplace, including HealthCare.gov. CMS says every one of the canceled policies involved help from an insurance agent or broker. This was Marketplace coverage, not Medicare. If you are new to how the Marketplace works, start with what the Health Insurance Marketplace is.
Suspicious Is Not the Same as Proof
The government says the policies it reviewed had several warning signs showing up together:
- Some applications had unresolved citizenship or immigration verification issues.
- Insurers could not identify medical claims on the policies.
- In many cases, insurers could not reach the consumers connected to them.
Put together, that can look suspicious. But no single warning sign proves fraud. CMS itself says having no medical claims does not automatically mean a policy was unauthorized. Plenty of healthy people pay for insurance and barely use it.
The real question is whether the person knowingly approved the enrollment and was actually eligible for the coverage.
How Someone Can Be Enrolled Without Knowing It
Imagine someone talks with an insurance agent because they want to compare prices. They give the agent enough information to look at options, but they never agree to buy a plan.
Months later, a tax form arrives showing that federal premium assistance was paid toward insurance in their name. On paper, that person looks like an enrollee. In real life, they may have had no idea the policy existed.
That is why an unauthorized enrollment is not automatically proof that the consumer committed fraud. A person deliberately lying to get benefits is one thing. A dishonest broker enrolling somebody without permission is something very different.
What Government Auditors Found
This problem is not theoretical. The Government Accountability Office (GAO) reported this summer that federal Marketplace safeguards did not always prevent unauthorized actions by agents and brokers.
GAO found weaknesses in how consumer consent was checked. It found situations where agents who were not already connected to a person’s account could gain access to Marketplace information, and cases where consumers were not always clearly notified about broker activity.
Complaints tied to confirmed unauthorized enrollments and plan changes increased more than fourfold from 2023 through 2025.
Why Would a Broker Do This?
Money can be part of the answer. Insurance agents and brokers can provide a useful service, because choosing health coverage can be confusing, and most of them are doing legitimate work.
But agents can also receive commissions from insurance companies when people enroll. For a dishonest operator, more enrollments can mean more money. That creates an incentive to sign people up, switch their plans, or attach themselves to an account even when the consumer never gave permission.
Federal prosecutors have already documented serious cases. In April 2026, the Justice Department announced that AP of South Florida agreed to plead guilty in an ACA enrollment fraud case. Prosecutors said the brokerage used thousands of vulnerable consumers in fraudulent applications that resulted in about $141.5 million in unwarranted federal subsidies. Some consumers also had disruptions because the plans created through those enrollments did not fit their medical needs.
What It Can Mean at Home
This is where it becomes personal. Your doctor may no longer be in network. A prescription you depend on may not be covered. Your deductible or premium could change. For a refresher on how those costs work, see copay vs. coinsurance vs. deductible.
Or you could find out during tax season that premium tax credits were paid for a plan connected to your identity. What looks like a number in a government database can become a pharmacy problem, a doctor’s office problem, or a tax problem at your kitchen table.
The 2027 Pause on New Brokers
CMS is now trying to tighten the system. The agency is temporarily blocking certain new agents and brokers from registering for the 2027 federal Marketplace.
In general, someone who did not already have a plan-year 2026 Exchange agreement will not be able to complete a new 2027 registration until February 1, 2027, unless CMS changes or lifts that restriction.
CMS says newer brokers showed a disproportionate amount of suspicious activity. They made up roughly 11 percent of registered brokers with at least one active 2026 enrollment, but about 30 percent of the 569 brokers who received notices of intent to terminate during July and August.
That does not mean every new broker did something wrong. Broker groups have pushed back, arguing that legitimate new professionals could also be kept from helping consumers.
New Rules for Proving Consent
Another change may matter even more. CMS says agents and brokers will have to reestablish their identities using Login.gov or ID.me, and agent-assisted applications will need verifiable identifying information.
The agency also says electronic consumer authorization will be required before an agent or broker can take action on an application or enrollment.
That last part is important. A broker saying, “Yes, this customer gave me permission,” is not the same as the customer confirming it on their own. Think of the verification code your bank sends when someone tries to log in to your account. It adds a checkpoint where the actual person has to take part, which makes it harder for somebody else to act in your name without you knowing.
How to Check Your Marketplace Coverage
Sign In Directly
Go directly to HealthCare.gov or your official state Marketplace and sign in to your account. Do not use a link from an unexpected text, email, or social media ad.
Review Every Detail on the Application
Check the plan name, the people listed in your household, your mailing address, your income information, and the agent or broker connected to the application. If you see a name you do not recognize, do not just ignore it.
Compare It With Your Insurance Company
Compare what you see in your Marketplace account with what your insurance company says you actually have. Make sure your coverage is active and verify your premium. Check that your doctors are still in network, and if you take regular medications, confirm your prescriptions are still covered.
Document Before You Change Anything
If something looks wrong, document it before making changes. Save screenshots, letters, and emails, and write down names and dates.
If You Were Enrolled or Switched Without Permission
Contact the official Marketplace Call Center. Ask what change was made, when it happened, which agent or broker was connected to the enrollment, and what options you have to correct the record or restore the right coverage.
You can also contact your state insurance department if a licensed insurance agent appears to be involved.
Be cautious with anyone offering “free money,” cash cards, or supposedly free insurance without clearly explaining what you are signing up for. Premium assistance is tied to eligible health coverage. It is not free cash. Never hand over identity documents or a verification code unless you understand exactly who is asking and what they will do with it.
What This Means for You
If you buy health insurance through the Marketplace, this is a good moment to look at your account, even if nothing seems wrong. A plan you did not choose, a broker you never met, or a household member you did not list are all things you can catch yourself.
The deeper story is about control. Fraud prevention should stop fake enrollments and dishonest brokers, but it also has to protect real people from having coverage opened, changed, or canceled because somebody else was able to act in their name.
Frequently Asked Questions
Why did 760,000 people lose health insurance?
CMS canceled roughly 315,000 ACA Marketplace enrollments it says were unauthorized, effective August 31, 2026. Those enrollments covered more than 760,000 people. Every canceled policy involved an insurance agent or broker.
Does an unauthorized enrollment mean the person committed fraud?
No. Some people were signed up or switched into a plan by a broker without their permission. In that case, the consumer may be the victim, not the one who did something wrong.
Does having no medical claims mean a policy was fake?
No. CMS says no claims does not automatically mean a policy was unauthorized. Many healthy people pay for insurance and rarely use it.
How can I tell if a broker changed my Marketplace plan?
Sign in directly at HealthCare.gov or your state Marketplace. Check the plan name, household members, address, income, and the agent or broker listed on your application.
What should I do if I was enrolled without permission?
Save screenshots, letters, and emails, then call the official Marketplace Call Center. Ask what changed, when, and which broker was involved. You can also contact your state insurance department.
What is changing for brokers in 2027?
Certain new brokers cannot register for the 2027 federal Marketplace until February 1, 2027. Brokers must also reverify their identities, and electronic consumer authorization will be required before a broker acts on an application.
Key Takeaway
Your health plan should reflect a choice you made, not a commission somebody else wanted.
- Sign in directly to HealthCare.gov or your state Marketplace and review your application.
- Look for a broker, plan, or household member you do not recognize.
- If something is wrong, document it and call the official Marketplace Call Center.
