CMS Canceled 760,000 Healthcare.gov Plans After a Silence Test

The Centers for Medicare and Medicaid Services canceled about 315,000 HealthCare.gov enrollments covering more than 760,000 people on August 31, 2026. Vice President JD Vance and CMS Administrator Dr. Mehmet Oz announced the cut on September 22 and said it should return roughly $2.2 billion in advance premium tax credits.

Insurers had been told to reach those households. Files with no reply, no claims, and unverified citizenship or immigration papers were treated as unauthorized.

CMS Canceled About 315,000 Marketplace Enrollments in August

The agency’s fact sheet says CMS canceled approximately 315,000 enrollments covering more than 760,000 people after a joint review with health insurance companies. The cut applies to the federal marketplace, HealthCare.gov and the states that use that platform, not every state-run exchange.

HHS Secretary Robert F. Kennedy Jr. said CMS is “shutting down unauthorized Marketplace enrollments and returning approximately $2.2 billion in taxpayer-funded subsidies.” Oz said the agency is using its data and enforcement tools “to identify fraud and abuse, stop it, and recover taxpayer dollars.”

Vance, who leads the White House Task Force to Eliminate Fraud, put the blame on brokers paid to feed people into the system while the government, he said, was not checking eligibility. “What do you have? Of course, rampant, rampant fraud,” he said. He also described the canceled group as a mix of phantom people and real people who do not meet the rules, including some signed up without their knowledge.

WHAT WE KNOW

• The cut: Approximately 315,000 enrollments covering more than 760,000 people were canceled on August 31, 2026.
• The money: CMS expects to return roughly $2.2 billion in advance premium tax credits tied to those files.
• The channel: The action covers the federally facilitated exchange and states that use the federal platform.
• The brokers: CMS has sent termination notices to over 200 agents and brokers since January 2026 and 569 intent-to-terminate notices this summer.

WHAT IS UNCONFIRMED

• The split: CMS has not published how many of the 760,000 were fabricated identities versus real people who never answered.
• The next round: Vance said about 419,000 more enrollments face added checks; the fact sheet does not say how many of those will be dropped.
• The safety net: CMS has not described a special path for someone who says the file was theirs and the letter never arrived.

Oz told the briefing those files were treated as phantoms because officials believe most either do not exist or never knew they had a plan, having never filed a claim and remaining unreachable after repeated attempts. That is the method. It is also how a healthy person, or a person who moved, looks in the data.

Silence and Unused Care Were the Fraud Test

Cynthia Cox, who directs KFF’s Affordable Care Act program, said the administration sent insurers a list of about a million people and asked them to make contact. No answer inside 30 days, and the plan came off the books.

What we know is that the administration sent a list of about a million people to health insurance companies and asked these health insurance companies to try to make contact with those people. And if those people did not respond within 30 days, they ultimately had their plan canceled.

Cox said there is fraud in the marketplace, and it is also possible that qualified people lost coverage here. People move. They do not always check email or voicemail inside a 30-day window.

The September rule on broker registration described the August cancellations as broker-assisted 2026 policies without verified citizenship or immigration documents, and for whom issuers could not find claims or reach the consumer. Unused care is a weak fraud fingerprint. Healthy enrollees file few claims. A $0 or near-$0 subsidized plan gives a household little reason to watch the mail. A broker who enrolled someone without consent produces the same empty claim file as a person who simply did not get sick.

Vance and other officials were asked about that overlap and said they were confident these were phantom enrollees. Confidence is not a published match rate. The fact sheet says the enrollments were unauthorized after CMS’s existing process. It does not show how many of those households later proved they were real.

Newly Registered Brokers Carry the Highest Risk Flags

Broker fraud on HealthCare.gov is not a new complaint. The Government Accountability Office found that consumer complaints grew more than fourfold from 2023 through 2025 for unauthorized enrollments and plan switches, and that at least 160,000 federal marketplace applications in plan year 2024 had likely unauthorized changes. The September rule cites more than 624,000 such complaints from 2023 through 2025, about 300,000 of them in 2025.

CMS says agents and brokers who first registered for 2026 are a small share of assisted enrollments and a large share of the trouble. Compared with brokers who registered earlier, their assisted enrollments show higher rates of missing data and unresolved checks.

HOW NEW 2026 BROKERS COMPARE

This summer CMS issued 569 notices of intent to terminate exchange agreements for 2026 applications filed without identifying information such as a Social Security number. The response window for the first 100 of those notices has closed, and 66 already received termination notices. The remaining 469 are still in that process. Since January, the agency has sent termination notices to over 200 non-compliant agents and brokers.

CMS is also pausing new broker registration for 2027 for anyone without an active 2026 exchange agreement, through February 1, 2027 unless the agency changes the date. Oz said most of the fraud, a disproportionate share, is coming from that channel.

NEW CHECKS BEFORE OPEN ENROLLMENT

• Identity proofing: All existing agents and brokers must re-verify through Login.gov or ID.me.
• Traceable IDs: Broker-assisted applications must include Social Security numbers or immigration document numbers CMS can check for every non-newborn applicant.
• Self-serve lock: Brokers are blocked from attaching themselves to applications a consumer should finish alone on HealthCare.gov.
• Electronic consent: Before Open Enrollment, a broker will need electronic consumer authorization before acting on an application or enrollment.

Those rules aim at the commission machine that made silent enrollments cheap to produce. They do not restore a plan that already ended on August 31.

A 12 Percent Drop Came Before the Purge

This cut did not hit a stable market. KFF, drawing on CMS effectuated-enrollment files, found 19.2 million people in February 2026 with paid-up marketplace coverage, down from 21.8 million in 2025. That is a 12 percent decline, the first drop since 2019, and it lines up with the end of the extra premium tax credits at the close of 2025.

On average, premium payments net of tax credits rose 58 percent for people who signed up for 2026 coverage. A KFF follow-up survey found that about 9 percent of 2025 marketplace enrollees said they became uninsured for 2026, and that eight in 10 people who changed coverage or became uninsured cited cost. Seventeen percent of returning enrollees said they worried they could not pay premiums for the whole year.

WHERE 2026 ENROLLMENT FELL

KFF also found that the average marketplace deductible rose 37 percent, from $2,759 in 2025 to $3,786 in 2026, as shoppers moved into cheaper bronze plans. Bronze sign-ups grew from 7.3 million people (30 percent of selections) to 9.2 million (40 percent). People who kept coverage are already paying more when they use it. People who used it least were the ones the August filter was built to find.

Why Did Coverage End Weeks Before the Announcement?

The plans came off the system on August 31. The podium was September 22, 22 days later. A household that went to a clinic in early September could have been uninsured while still believing a card in a drawer was live. Insurers and clinics that bill those visits now have a closed enrollment to fight with, and the patient is the one who finds out at the counter.

That lag is the practical second hit. The first is the 30-day contact test. The second is a public notice that arrived after the coverage had already died. CMS says it will keep working with insurers to find more unauthorized enrollments, cancel them, and recoup past subsidy payments. It has not said how a person who was real, quiet, and late to the mail gets put back for the rest of 2026.

THE CUT AND THE CALENDAR AHEAD

1. August 31, 2026: CMS cancels approximately 315,000 plan year 2026 enrollments covering more than 760,000 people.
2. September 22, 2026: Vance and Oz announce the cut and a broker-registration freeze that takes effect the same day.
3. November 1, 2026: Open Enrollment for 2027 plans begins on HealthCare.gov.
4. December 15, 2026: Last day to pick a plan for coverage that starts January 1, 2027.
5. January 15, 2027: The HealthCare.gov Open Enrollment window closes.
6. February 1, 2027: The freeze on new broker registration is set to end unless CMS extends it.

If this were only a criminal case against named brokers, the public would expect charging documents next to the enrollment totals. The loud objection in the days after the briefing was that a fraud number this large arrived without a matching wave of new arrests. What CMS actually ran was an administrative purge: no contact, no claims, unverified papers, then a closed file.

Another 419,000 Enrollments Face a Second Check

Vance said officials will run added verification on about 419,000 more people, to confirm they are legal residents and meet income limits. “We expect that most of these people are fraudulently enrolled,” he said. The CMS fact sheet issued the same day does not carry that 419,000 figure, and it does not set a date for a second mass cancellation.

Cox and other researchers asked for more transparency on how CMS avoids cutting legitimate plans. Vance’s team said it tried to reach people in several ways and treated non-response plus no claims as enough. That standard will be applied again if the second list moves the same way.

A real person who never used the plan is the cheapest enrollee in a risk pool, the one whose premium helps pay for someone else’s surgery. Drop that person and the remaining pool is sicker on paper. Drop a phantom and the subsidy leaves with no patient attached. CMS has not separated those two groups in the 760,000, so the $2.2 billion cannot be read as pure waste recovered. Some of it is waste. Some of it may be coverage that a quiet household will miss the first time a bill arrives.

The Nov. 1 Window Opens Under a Broker Freeze

HealthCare.gov’s calendar is unchanged even as the broker channel narrows. Open Enrollment starts November 1, 2026. Enroll by December 15 for coverage that starts January 1, 2027. The federal window runs through January 15, 2027, with later starts for plans picked after December 15. The new-broker freeze lasts until February 1, 2027, which means the entire federal shopping season runs with no fresh agents added to the roster.

2027 SHOPPING DATES ON HEALTHCARE.GOV

• November 1, 2026: Open Enrollment begins, 40 days after the September 22 announcement.
• December 15, 2026: Deadline for a January 1, 2027 coverage start.
• January 15, 2027: Last day to enroll or change a 2027 plan on HealthCare.gov.
• February 1, 2027: Scheduled end of the freeze on new broker registration.

Existing brokers who keep their 2026 agreements can still help people enroll. Households that used a new 2026 helper, or that never knew they had a plan, will be doing that work themselves, through Login.gov identity checks and the extra document demands CMS is adding. The August cancellations already happened. The next test is whether the people on those files, and the 419,000 still under review, show up on November 1 with papers in hand, or stay uninsured through the fall.
