The new price transparency rules: how to get a real price before scheduled care

On October 5, 2026, two federal actions landed on the same day, pointing the same direction. The Centers for Medicare & Medicaid Services, with the Departments of Labor and the Treasury, finalized updates to the Transparency in Coverage rules — the ones that govern how insurers and employer plans publish what they have negotiated with providers. The same day, the Federal Trade Commission’s chairman sent letters to 24 of the nation’s largest healthcare services companies, warning that incomplete or misleading price information can be an unfair or deceptive practice under the FTC Act.

Neither action changes what any procedure actually costs. Both are about something upstream of that: making sure you can find out what you will owe before you commit to care, not after the bill arrives. This guide explains what changed, when it takes effect, and — the part that matters — what you can ask for today.

What got finalized, and what it fixes

The 2020 transparency rules required group health plans and insurers to publish machine-readable files of their negotiated in-network rates and out-of-network allowed amounts. In practice the files grew enormous and tangled, which limited who could build anything useful on top of them. The final rule CMS announced (docket CMS-9882-F) restructures that data:

• Quarterly instead of monthly updates for the in-network rate and out-of-network allowed amount files. CMS projects net savings of about $174.5 million a year for plans and insurers starting in the second year of implementation.
• One file per provider network instead of one per plan or policy — plans sharing a network share a file.
• A single standardized format (JSON), where the old rules allowed any open format.
• “Ghost rates” removed: rates for item-and-provider combinations the provider’s specialty would rarely bill (a podiatry rate for heart surgery, to use CMS’s kind of example) no longer pad the files.
• More out-of-network data than before: the minimum number of claims for a service to be reported drops from 20 to 11, and allowed amounts are aggregated by market type — large group, small group, individual, self-insured.
• Accountability attached: each file must carry an attestation that the data is accurate and complete as of its date, with the name of a responsible executive — the CEO, president or a designated senior official — encoded in it.
• Easier to find: plans must post a plain-text index at the root of their public website and add a “Price Transparency” link to their site footer.

All of this is plumbing, and most readers will never open a JSON file. It matters because the comparison tools you do touch are built on this data. CMS’s release notes that prices among the top 25% most expensive healthcare services have fallen by about 6.3% per year since the first transparency rules took effect. Treat that as an early, encouraging signal from the agency’s own summary — not a promise about your bill, which is set by your plan, your provider and what gets negotiated.

The dates that matter

Change	When it takes effect
The rule itself	60 days after publication in the Federal Register
Rebuilt in-network and out-of-network files	5 months after Federal Register publication
Index, taxonomy and utilization files	11 months after Federal Register publication
Cost-sharing estimates by phone	Plan years beginning on or after January 1, 2027
Prescription drug price files	Publishing starting December 2027 (schema to be finalized around May 2027)

Note the anchor points: CMS announced the rules on October 5, 2026, but the clock for the first deadlines starts when they are published in the Federal Register, so the exact calendar dates are not yet fixed. The phone requirement is pegged to plan years instead — for most employer plans, January 1, 2027.

Who is covered

These rules govern employer group plans and health insurance issuers — employer coverage, marketplace plans and other individual coverage. They are not Medicare rules; Medicare’s prices are published through separate CMS tools. If you are comparing coverage before open enrollment, our guide Premium, Deductible, Copay, Out-of-Pocket Max: How US Health Insurance Costs Stack is the companion piece to this one.

One scope nuance worth knowing: so-called grandfathered plans are largely exempt from the file requirements, but the new phone obligation reaches them too, because meeting it also counts as compliance with section 114 of the No Surprises Act.

The part you can use soonest: phone estimates

Since January 2023, plans and insurers have been required to operate an online tool that gives you personalized cost-sharing information — what a given service is expected to cost you under your plan. Starting with plan years that begin on or after January 1, 2027, the same information must also be available by phone on request.

That sounds bureaucratic until you need it. It means you can call the member-services number on your card and ask, in plain terms: “I’m scheduling an MRI at this facility. What will my plan pay, and what will I owe?” The answer is an estimate, not a guarantee — final amounts depend on how the claim processes. But it converts your cheapest available information source from a guess to a quote. From 2027, do it by phone, and write down the date, the representative’s name and the figure you were given.

The FTC’s warning: a partial price can be a deceptive one

The FTC letters are the enforcement-minded half of the same day’s news. The commission reminded 24 large healthcare services companies that:

• Failing to provide timely, accurate and complete price information — particularly for routine, non-emergency care scheduled in advance — can violate Section 5 of the FTC Act as an unfair or deceptive practice.
• Complying with the CMS transparency rules is a baseline, not a safe harbor from FTC liability.
• Omissions can mislead: a disclosure that leaves out physician or facility fees, or that covers only part of the expected course of care, can be deceptive, because patients may reasonably take it as the total price.
• Inaccurate disclosures are no better than absent ones.

The FTC’s own framing of the consumer problem is blunt: patients are routinely asked to commit to care without knowing the cost, and prices for the same service “often differ dramatically” from one facility to the next. Chairman Ferguson urged the companies to review their price-disclosure practices and correct them. The letters follow the FTC’s creation of a Healthcare Task Force earlier in 2026 and, days before, an FTC and state lawsuit against contact-lens retailer Lens.com over misrepresented prices.

For readers, the practical meaning is simpler than the legal theory: the question “does that number include everything?” is not just prudent — regulators have told the industry, in writing, that it is the right question to ask.

What to do before your next scheduled procedure

1. Ask the provider’s office for the total expected price — and ask the specific question: does that include the facility fee and the physician’s fee? Those are exactly the two omissions the FTC flagged.
2. Ask your insurer too. Use the plan’s online cost-sharing tool now; from plan years starting January 1, 2027, call and get the same estimate by phone. Two independent numbers beat one.
3. Compare facilities for the same service if the scheduling is non-emergency and you have a choice. The price differences are the FTC’s stated example of what competition is supposed to fix.
4. Get it in writing, or log the call. If the later bill doesn’t match, request an itemized bill and reconcile it against the estimate line by line before paying anything you don’t recognize.
5. Know where the backstops are. Billing dispute rights and protections against surprise balance bills vary by state and by plan type — your state insurance department can tell you what applies to you.

One caution

Regulators’ names get borrowed by scammers. The FTC notes plainly that it never demands money, makes threats or promises prizes; if someone contacts you claiming a refund or a penalty tied to your medical bills, hang up and report it at reportfraud.ftc.gov. The same checklist we published for spotting fake government contacts — Is That Really America.gov? A Scam-Spotting Checklist — applies to healthcare payment scams as well.

Bottom line

The rebuilt files and the FTC letters are the machinery of a bet regulators have now made twice in one day: that patients who can see real prices will use them. The consumer-facing payoff arrives on a schedule — phone estimates with 2027 plan years, better comparison tools as the new files roll out over the following months. You don’t have to wait for any of it to ask better questions at your next appointment, because the two questions that matter — “what is the total, including every fee?” and “what will my plan actually pay?” — cost nothing today.
