The Price Is Published. Nobody Tells You Where.

You Can Price a Flight. Why Not an MRI?

Call a hospital and ask what a knee MRI costs. You will almost certainly hear some version of "that depends on your insurance."

It is a true sentence. It is also a door closing.

So most people do the only thing left. They show up, get the scan, and find out the price six weeks later, printed on a bill, when the decision is long past changing.

Here is what almost nobody knows.

Since January 1, 2021, every hospital operating in the United States has been legally required to publish online — free, without a login — the actual dollar price it negotiated with every single insurer, plus the discounted price it will accept from someone paying cash. Not a range. Not an average. The rates themselves.

And since plan years beginning January 1, 2024, your health plan has been required to tell you, on request, your expected share of the cost for any covered item or service — before you get it.

Both of those are federal rules. Both are in force right now. Neither is advertised.[2, 5, 12]

So the problem is not secrecy. It is address. The number exists, sits on a public server, and no one at the front desk is going to hand you the link.

This guide is the address book. Four places the price actually lives, in the order you should try them. What changed on January 1, 2026, and why it made the files far more useful. The one estimate Congress promised insured patients that still does not exist in 2026. And the things a price will never tell you, so you do not walk in overconfident.

One honest warning up front. None of this helps in an emergency. You cannot shop while you are bleeding, and you should not try. Everything here is for care you can schedule.

One Procedure Has Five Official Prices

The reason "what does it cost" has no clean answer is that the question has five answers at the same time. Federal regulation actually names them. A hospital’s standard charges are defined as five different numbers for the same item.

Gross charge. The list price from the hospital’s internal price list, called the chargemaster. It is the sticker on the window. Essentially nobody pays it.

Payer-specific negotiated charge. What the hospital and one particular insurance plan agreed on. This is the real price, and it is different for every plan.

De-identified minimum and maximum negotiated charge. The lowest and highest rate the hospital has agreed to with anyone, with the names stripped out. Useful for a sanity check.

Discounted cash price. What the hospital will take from a person paying cash, with no insurer in the middle.[3]

None of those five is your bill.

Your bill comes from a sixth number: your share of the negotiated charge. That depends on your deductible, your coinsurance, your copay, and how much you have already spent this year. The industry word for the negotiated amount a plan will recognize is the allowed amount — and if a provider is out of network, you can be charged the difference between what they bill and what the plan allows.

So the price hunt has two legs, and you need both. Leg one: what does this place charge for this thing. Leg two: what portion of that lands on me.[49, 51]

One more thing hides inside "the price," and it surprises people every time.

The regulation says a hospital’s items and services include, among other things, "use of the facility and other items (generally described as facility fees)" and "services of employed physicians and non-physician practitioners." So a hospital price can be two invoices wearing one name: a charge for the room and machine, and a separate charge for the human being who read the scan.

Hold on to that. It comes back in almost every section below.[3]

Four Doors, and Which One to Try First

Four separate legal mandates put medical prices in public. They were written at different times by different people and they do not point at each other. That is why nobody hands you a single link.

Door 1 — the hospital’s machine-readable file. Every hospital must post one big data file listing all five standard charges for every item and service, updated at least once a year. It is the most complete source and the least friendly.

Door 2 — the hospital’s consumer display. The same hospital must also show at least 300 "shoppable" services in a plain-language, searchable format — or run a price estimator tool instead.

Door 3 — your insurer’s cost tool. Your plan must give you a personalized estimate of your own cost-sharing, on request, for any covered item or service.

Door 4 — Medicare’s lookup. If you are on Original Medicare, the government publishes national average prices for outpatient procedures and what your copay would be.[6, 7, 12, 46]

The order that works in practice is not the order they were written in.

Start with Door 3 if you have insurance. Your insurer already knows your deductible balance, so it is the only door that can produce a number with your name on it in one step.

Go to Door 1 or 2 to compare hospitals, or when the insurer’s tool gives you a shrug. The hospital file is the only place you can see what a competitor across town agreed to for the same code.

Use Door 4 if you are on Medicare, or simply to get a reality anchor. Medicare rates are public, stable, and a reasonable floor to think from.

And if you plan to pay cash, the hospital’s discounted cash price in Door 1 is the number that matters most — more on that later, because paying cash has a cost that is not on the price tag.

Door 1: The File Every Hospital Must Post

The rule is short and blunt. A hospital must "establish, update, and make public a list of all standard charges for all items and services online."

Not a summary. Not a brochure. A single digital file, in a format a computer can read, that since July 1, 2024 has to follow a template CMS publishes. That template is why files from two different hospitals can finally be compared at all.

It must be free. No registration, no account, no password, no giving them your name. Those are written into the regulation, not into a courtesy policy.[5, 6]

Finding it used to be the hard part, so the rule fixed that too.

The file has to be named in a fixed pattern: the hospital’s tax ID, an underscore, the hospital name, an underscore, then standardcharges and either .json or .csv. And since January 1, 2024, the hospital’s website must carry a small text file in its root folder pointing at the data, plus a link in the site footer.

That footer link is the single most useful sentence in this article. Scroll to the very bottom of any hospital’s homepage and look for wording like "price transparency" or "standard charges." It is supposed to be there.[6, 33]

Before you go hunting, know one blank spot on the map.

Federal and state hospitals are deemed compliant without posting anything. That covers hospitals run by the Department of Veterans Affairs, military treatment facilities run by the Department of Defense, hospitals operated by an Indian Health Program, and state forensic hospitals that treat only people in custody.

If your care is at one of those, this door does not open. Not because someone is hiding the price, but because the rule never asked them.[4]

What Changed on January 1, 2026

For years these files had a loophole big enough to drive a truck through.

Hospitals do not always negotiate a flat dollar amount. Plenty of contracts say things like "sixty percent of billed charges" or point at a fee schedule. When that was the case, the hospital could simply write the formula into the file. Technically compliant. Completely useless to a patient, who has no way to turn "a percentage of something" into a number.

That closed on January 1, 2026.[6]

Three changes took effect that day, and CMS began enforcing them on April 1, 2026.

Real dollars behind every formula. When a negotiated charge rests on a percentage or an algorithm, the hospital must now publish the 10th percentile, the median, and the 90th percentile of what it actually got paid for that item — plus how many payments those figures are built on. The lookback runs 12 to 15 months. In plain terms: instead of a formula, you now see the spread of real money that changed hands.

A named human signs for it. The file must carry an attestation that the data is true, accurate and complete — and must encode the name of the chief executive, president, or senior official who oversaw it.

A National Provider Identifier. Hospitals must include their Type 2 organizational NPI, so a file can be matched to the actual facility instead of a marketing name.[6, 3, 19, 23]

Why the percentile change matters more than it sounds.

A median tells you the typical payment. The 10th and 90th percentiles tell you how much the price moves — and a wide gap is itself information. It usually means the item is bundled differently, or billed with modifiers, or that your bill will depend on details nobody mentioned at scheduling.

The claim count matters too. Three payments and a median are a rumor. Four hundred payments and a median are a price.

CMS was explicit about the goal: hospitals must "make their MRFs more useful and comparable by publishing actual dollar-based pricing data." That is the whole point of the 2026 version of this rule.[23, 31]

Opening the File Without Being a Data Analyst

These files are big. A large hospital’s list can run to hundreds of thousands of rows, because it holds every payer and every item. That sounds hopeless until you realize you only need one row.

Work in this order.

One: find the link. Go to the hospital homepage, scroll to the footer, look for "price transparency" or "standard charges." If it is not there, the small text file in the site root is supposed to point at it.

Two: get the code, not the name. "MRI of the knee" is not searchable. The CPT or HCPCS code is. Ask the ordering doctor’s office for the exact code they will bill, including any modifier. This single step separates people who find a price from people who give up.

Three: open it in a spreadsheet if it is a CSV, and filter by that code. If it is JSON, most hospitals also offer CSV.[6, 36]

Once you have your row, four columns carry the meaning.

The payer-specific negotiated charge matched to your plan is your target number. The discounted cash price is the alternative if you skip insurance. The de-identified minimum and maximum tell you where your plan sits in the pack — if your plan’s rate is near the maximum, that is worth knowing before you book.

Then check whether the row is a flat dollar amount or an algorithm. If it is an algorithm, look for the median and the 10th and 90th percentile allowed amounts that hospitals have had to publish since January 2026, and the count of payments behind them.[6, 3]

Two honest frictions, because pretending they do not exist would waste your afternoon.

Plan names are a mess. The same insurer can appear under a dozen spellings across different hospitals. This is not your imagination — CMS said so itself in July 2026, noting that "variations in the name of a payer or a plan across hospitals’ MRFs" make comparison hard. Search for a fragment, not the full marketing name, and check your insurance card for the network name.

Contracts have side terms. Outlier clauses, stop-loss provisions, tiering and carve-outs can change what actually gets paid. CMS is currently asking the public how to standardize the reporting of exactly those terms. Until that lands, treat the number as a strong estimate, not a quote.

If you want a shortcut, CMS publishes a free online validator and a public data dictionary that explain every field in the template.[23, 35, 36, 34]

Door 2: The 300 Services a Hospital Must Show in Plain Language

The giant data file is for researchers. The second requirement is for you.

Every hospital must also display its prices for at least 300 shoppable services in a consumer-friendly way. Seventy of those are specified by CMS so that the same common services appear everywhere; the hospital picks the rest. If it does not offer 300, it shows as many as it has.

A "shoppable service" has a simple definition in the rule: a service that can be scheduled in advance. Imaging, lab work, an outpatient visit, a colonoscopy. That definition is the honest boundary of this entire article.[7, 3, 37]

There is a substitution most hospitals now take. Instead of publishing a list, a hospital may run an internet-based price estimator tool and be treated as compliant — provided the tool covers the same services, actually tells you what you would owe the hospital, and is prominently displayed, free, with no account required.

So when you land on a hospital site and find a calculator rather than a table, that is not a dodge. That is the rule working as written.

Whatever form it takes, the display has to be free, usable without an account or password, usable without handing over personal identifying information, and searchable by service description, billing code, and payer. If a site demands your date of birth before showing a price, it is not meeting the standard.[7]

One limitation to keep in your pocket. The consumer display only has to be updated once a year. The big data file carries a date stamp of its last update; the display may be older than you assume.

So use Door 2 to narrow the field quickly — three hospitals, rough numbers, one afternoon — and then confirm the finalist against the machine-readable file or your insurer. Cheap and fast first, precise second.[7]

Door 3: Your Insurer Already Owes You a Personalized Number

This is the door almost nobody uses, and it is the one built for your exact situation.

Under the Transparency in Coverage rules, a group health plan or insurer must give a participant, on request, an estimate of that person’s own cost-sharing liability for a covered item or service — accurate as of the time of the request.

The rollout came in two steps. For plan years beginning on or after January 1, 2023, it covered 500 specified items and services. For plan years beginning on or after January 1, 2024, it covers all covered items and services. That second date is why this door is worth knocking on today.[12, 16, 42]

What comes back is more than a number. The estimate is built from the information the plan already holds, so a proper answer tells you the negotiated rate behind it, what you have already put toward your deductible and out-of-pocket limit, and whether the service carries a prerequisite such as prior authorization.

That last item is quietly the most valuable. A price is meaningless if the plan later refuses the service for lack of prior authorization, and this is the cheapest moment to discover that.

You are also not limited to a website. The rules require the information to be available through a self-service tool and on paper if you ask — and in December 2025 the Departments proposed adding by phone as well. That last part is a proposal, not a requirement; see the closing section.[12, 21]

Now the exclusions, because they are real and worth checking before you spend an hour on hold.

The requirement does not apply to grandfathered health plans, to account-based plans such as health reimbursement arrangements, or to short-term limited duration insurance.

Medicare and Medicaid are not covered by this rule either. They are not the private plans the regulation addresses, which is exactly why Door 4 exists.

If you are still choosing coverage rather than pricing a procedure, the deductible and out-of-pocket limit you pick will move these numbers more than any hospital comparison will. Our guide to choosing a health plan covers that side.[12, 11]

The Estimate Congress Promised Insured Patients Still Does Not Exist

Everything above is a workaround. Congress actually designed something better, and it was supposed to be running four and a half years ago.

The No Surprises Act created the Advanced Explanation of Benefits. The idea is clean. You schedule a procedure. Your provider sends your plan a good faith estimate. Your plan combines it with your benefits and sends you, in advance, a document showing the network status, the contracted rate, what you will owe, and where you stand against your deductible.

No spreadsheets. No phone tree. One paper, before the appointment.

The statute applied to plan years beginning on or after January 1, 2022.[17, 43]

It never started. And the government said so, in writing, in its own Federal Register notice.

HHS implemented the good faith estimate for uninsured and self-pay people in the October 2021 interim final rule. But in that same rulemaking it deferred enforcement of the part covering insured people, and deferred enforcement of the AEOB provisions in the Internal Revenue Code, ERISA, and the Public Health Service Act.

The stated reason was practical, not political: there was no standard for moving estimate data from providers to plans, and building one would take time.

In September 2022 the Departments issued a request for information asking how it should work. That request is where the trail ends.[17]

As of July 2026, there is still no rule.

Search the Federal Register for "advanced explanation of benefits" and you get a handful of documents, none of which implements it. The December 2025 Transparency in Coverage proposal runs to hundreds of pages and mentions the AEOB exactly once, in a list of things the No Surprises Act called for.

So here is the shape of American medical pricing in 2026, and it is worth saying slowly.

A person with no insurance has an enforceable right to a written estimate before scheduled care. A person with insurance has a right to ask their plan a question — and no right at all to the combined document the law describes.

The people who bought coverage got the weaker paperwork. That is not a conspiracy. It is a deadline that passed and a rule that was never written.[17, 21, 13]

The Switch: You Can Choose to Be Self-Pay, and the Estimate Right Follows

Read the definition in the regulation and something opens up.

An "uninsured (or self-pay) individual" is not only a person without coverage. It also means a person who has benefits for an item or service "but who does not seek to have a claim for such item or service submitted to such plan or coverage."

Read that again. The written-estimate right does not attach to whether you own an insurance card. It attaches to how you decide to pay for this one service.

If you tell a provider you are paying for this yourself and not putting it through your plan, you are self-pay for that service — and the good faith estimate obligation applies to you.[13]

That is a genuine lever, and it is the reason this section exists. It is not a loophole and not a trick — it is the definition doing exactly what it says.

We are deliberately not repeating the mechanics here. How quickly the estimate must arrive, what it must include, and what happens when the final bill lands far above it are all covered in detail in our guide to the No Surprises Act and good faith estimates. Read that before you use this lever.

What belongs here is the decision itself, and it has a cost. Going self-pay means the money you spend usually stops counting toward your insurance. That is the next section, and you should not pull this lever before reading it.[13]

When the Cash Price Beats Your Insurance, and When It Quietly Costs You

Sometimes the cash price is lower than the rate your own insurer negotiated. It sounds impossible. It is common enough that the regulation gives it a name and forces hospitals to publish it.

The reason is unglamorous. A cash payment costs the hospital nothing to collect. There is no claim to file, no denial to appeal, no ninety-day wait, no billing staff time. Hospitals price that convenience.

So a person with a $6,000 deductible can walk in, ask for the discounted cash price, and pay less than their "covered" rate would have been. This is a real and legal outcome.[3, 25]

Now the part that is missing from most advice, and it can cost far more than you saved.

Money you pay outside your plan usually does not count toward your plan.

The federal glossary defines your deductible as "the amount you pay for covered health care services before your insurance plan starts to pay." And your out-of-pocket limit explicitly does not include "anything you spend for services your plan doesn’t cover."

If you never file the claim, the plan generally never sees the spending — so the deductible does not move and the out-of-pocket ceiling does not get closer. Some plans will let you submit a paid receipt for credit. Many will not. This is a question to ask your plan before you pay, not after.[49, 50]

A simple way to decide.

Cash tends to win when the service is small and predictable, when you are early in the plan year with a high deductible you realistically will not reach, and when the published cash price is clearly below the negotiated rate.

Cash tends to lose when the bill is large, when you are already close to your deductible or your out-of-pocket limit, or when there is any chance of a complication that turns a scheduled procedure into a hospital stay.

That last one deserves weight. The out-of-pocket limit is the only thing standing between you and an unlimited bill. For a 2026 Marketplace plan it cannot exceed $10,600 for one person or $21,200 for a family. Every dollar that does not count toward it leaves that ceiling exactly where it was.[50, 52]

Same Code, Three Buildings, Three Prices

Here is the lever that moves the most money for the least effort, and almost nobody pulls it.

The identical procedure, with the identical billing code, done by the identical doctor, can be priced three different ways depending on the building it happens in: a hospital outpatient department, a freestanding ambulatory surgery center, or a doctor’s office.

This is not a rumor. The price transparency rule itself assumes it. Hospitals must encode their standard charges separately for the inpatient setting and the outpatient department setting, and must state where the shoppable service is provided. The regulation is built around the fact that setting changes the number.[6, 7]

The mechanism has a name: the facility fee.

When a service happens inside a hospital outpatient department, the bill can carry a charge for the facility on top of the charge for the professional work. Recall that the regulation lists "use of the facility and other items (generally described as facility fees)" as its own item.

The catch is that a "hospital outpatient department" does not have to look like a hospital. A clinic in a strip mall can be owned by a health system and billed as a provider-based department, complete with the facility fee. From the parking lot you cannot tell.

So add one question to every appointment you schedule: "Is this billed as a hospital outpatient department, or as an office visit?" The answer can move a bill by hundreds or thousands of dollars, and it costs you nothing to ask.[3, 44, 45]

Door 4: Medicare Publishes Its Prices, and Anyone Can Read Them

Medicare does not negotiate in private. It sets rates, publishes them, and runs a consumer tool on top of them.

Procedure Price Lookup shows national average costs for outpatient procedures — what Medicare pays, and what your share would be — and shows them separately for a hospital outpatient department and an ambulatory surgery center. That is the site-of-service gap from the last section, quantified, for free, by the government.

Two caveats so you use it honestly. The figures are national averages, not your local price, and they describe Original Medicare, not Medicare Advantage, where the plan sets its own cost-sharing.[46, 48]

Even if you are decades away from Medicare, the tool is useful as an anchor.

Medicare rates are the closest thing American health care has to a public reference price. When a hospital’s file shows a negotiated rate several times the Medicare figure for the same code, that is not proof of anything improper — commercial rates are routinely higher — but it tells you where you are standing, and it is a reasonable thing to raise when you ask about the cash price.

And while you are on the site, Care Compare puts quality measures for Medicare-certified hospitals next to the price question. Cheapest is not the goal. Knowing both numbers is.[46, 47, 25]

What a Price Will Never Tell You

A number in hand feels like control. Keep four blind spots in view so it does not turn into false confidence.

Other people bill you separately. The hospital’s price covers the hospital. The anesthesiologist, the pathologist reading your tissue, and the radiologist interpreting your scan may each be independent and may each send their own bill. This is the single most common reason a good estimate still ends in a surprise.

Complications are not priced. Every published figure describes the procedure going as planned. Nothing describes the night you did not expect to spend in a bed.[3]

A price is not an approval. Knowing the negotiated rate tells you nothing about whether your plan will authorize the service. Prior authorization and medical necessity are separate gates, and they are the ones that produce denials. If a plan says no, the price you researched becomes the price you owe in full.

Some prices are simply not published. Federal and state hospitals are deemed compliant without posting, and the consumer display only has to be refreshed once a year.

And if a bill arrives anyway that you did not agree to — an out-of-network doctor at an in-network hospital, or an emergency you could not shop — that is a different body of law with real teeth. Our guide to surprise bills and the No Surprises Act covers it, and if the bill is already in collections, start with medical bills and medical debt.[4, 7, 43]

Five Questions That Get You an Actual Number

Most price calls fail for the same reason: the caller asks a question the person on the other end cannot answer. "How much is a knee MRI" is unanswerable. These five are not.

One. "What is the exact CPT or HCPCS code you will bill, including any modifier?" Ask the office of the doctor ordering the test. Without the code you cannot search anything, and with it you can search everything.

Two. "Is this billed as a hospital outpatient department or a physician office, and what is the facility’s NPI?" This is the site-of-service question, and the NPI lets you match the right file.

Three. "What is your payer-specific negotiated charge for this code under my exact plan?" Read the plan name off your card, including the network. Do not say the insurer’s brand name alone.[6]

Four. "What is your discounted cash price for this code?" Ask even if you plan to use insurance. It is published anyway, and it is the only way to know whether your coverage is helping on this particular service.

Five. "Who else will send me a bill for this visit?" Anesthesia, pathology, radiology reading, the surgical assistant. Ask for names, then ask each one whether they are in your network.

Then make one call to your insurer with the same code and ask for your cost-sharing estimate, your remaining deductible, and whether prior authorization is required.

Two habits make all of this stick. Get it in writing — email or the plan’s message center is fine. And write down the date, the name, and the reference number of every call. An estimate you cannot prove you received is an estimate you did not receive.[3, 12]

One Knee MRI, Four Doors, One Afternoon

Put it together. Your doctor orders an MRI of the right knee, without contrast, and the scheduler offers you a slot three weeks out. You have three weeks, which is plenty.

Step 1, five minutes. Call the ordering office. Get the CPT code and any modifier, and ask which facilities they normally send patients to.

Step 2, fifteen minutes. Log into your insurer’s site and use the cost tool with that code for each facility. Write down the estimated cost-sharing, your remaining deductible, and whether prior authorization is needed. If the tool is broken or vague, call and ask for the same information in writing — the plan owes it to you on request.[12]

Step 3, twenty minutes. Open each hospital’s price file from the footer link. Filter to your CPT code. Compare four things across facilities: your plan’s negotiated charge, the discounted cash price, the de-identified minimum, and — if the rate is formula-based — the median allowed amount with its claim count.

Step 4, five minutes. Check the same code on Medicare’s Procedure Price Lookup, in both the hospital outpatient and ambulatory surgery center columns, as a reality anchor.

Step 5, ten minutes. Call your first choice and ask the five questions, especially who else will bill you.

Total: under an hour of ordinary phone-and-browser work, spread over a few days. For a large scan the spread between facilities is routinely the biggest single number in the whole exercise — larger, often, than anything you will renegotiate afterward.[6, 46]

You Have the Number. Lock It Down Before You Go.

A price you found is worth much more than a price you are told at check-in, but only if you fasten it down first.

Get the cash price in writing before the day of service. If you have decided to self-pay, the quoted discount is far easier to hold to when it exists as an email rather than a memory of a phone call.

Ask about the payment plan before you need one. The two questions that matter are whether it charges interest and whether the account goes to a third party. A hospital-held, interest-free plan is a fundamentally different object from a medical credit card.

And there is one door that opens best before care, which is exactly why it belongs here rather than in an article about unpaid bills.

A hospital that is tax-exempt under section 501(c)(3) has to satisfy the requirements of section 501(r). It must establish a written financial assistance policy saying who qualifies and how to apply. It must limit what it charges people who are eligible for that assistance to no more than the amounts generally billed to insured patients. And it must make reasonable efforts to determine eligibility before taking extraordinary collection actions.

Most people meet that policy after a bill has gone bad. Applying before a scheduled procedure changes what you are quoted, not just what you are chased for. Search the hospital’s site for "financial assistance policy" and read who qualifies — the income thresholds are often higher than people assume.[53, 54, 55, 56]

Two boundaries, stated plainly so you know where this guide stops.

If the bill has already arrived and is bigger than it should be, negotiating it down, handling collections, and protecting your credit are a different job with different tools. That is medical bills and medical debt.

If the plan denied the claim, the fight is an appeal with deadlines, not a price conversation. That is appealing a health insurance denial.

Everything in this article happens before either of those becomes necessary — which is the cheapest place to stand.

What Happens When a Hospital Ignores the Rule

Sometimes the file is not there, or it opens and the columns are empty, or the estimator demands an account. There is a process for that, and it starts with you.

CMS evaluates complaints from individuals, reviews outside analyses of non-compliance, audits hospitals, and can require a hospital official to certify the accuracy of the file. If it finds a problem, the sequence generally runs: a written warning notice, then a request for a corrective action plan, then a civil monetary penalty that gets published on a CMS website.

The complaint form is public, and CMS runs a contact page for exactly this.[8, 9, 30, 24]

The penalties are calculated by bed count, per day, and they run until the hospital fixes the problem.

A hospital with 30 beds or fewer faces up to $300 a day. One with 31 to 550 beds faces its bed count times $10 a day. Anything above 550 beds tops out at $5,500 a day. Those are maximums for the whole part, even if several requirements are violated at once.

Now the reality check, and it should shape how you spend your energy. CMS publishes every penalty notice it has issued. As of that page’s June 2026 update, the list held 28 notices in total — across more than five years and thousands of American hospitals.

File the complaint. It feeds the audits and the next round of rulemaking. Just do not wait on it. The data you can pull yourself today is worth more to you than an enforcement action you may never see.[10, 28, 29]

One more avenue, and it is separate from all of the above.

If you were uninsured or self-pay, received a good faith estimate, and then got a bill dramatically larger than it, there is a formal dispute process built for exactly that gap. It has its own eligibility rules and its own deadline. We cover it in the No Surprises Act guide rather than repeating it here.

And if any of this ends with a balance you have to carry, the thing that decides how much it finally costs is not the sticker price. It is how fast you retire it.[14]

What Is Already Law, and What Is Only Proposed

This area is moving, and the reporting around it routinely blurs a proposal into a requirement. Here is the line, drawn carefully.

Already in force. The hospital rules date to a final rule published in November 2019 and effective January 1, 2021. The insurer disclosure rules date to a final rule published in November 2020. In February 2025 an executive order directed the agencies to make prices standardized and comparable. Acting on it, CMS finalized the hospital changes in the CY 2026 outpatient payment rule, published November 25, 2025 and effective January 1, 2026, with enforcement from April 1, 2026. A technical correction followed in February 2026 and did not disturb the disclosure requirements.[15, 16, 18, 19, 20, 39]

Proposed, and not yet required. In December 2025 the Treasury, Labor and Health and Human Services departments proposed a substantial rewrite of the insurer disclosure rules. Among other things it would standardize the public pricing files, add data elements such as plan and network names, require a text file and footer links so the files can be found, and require plans to make pricing available by telephone in addition to online and on paper.

The comment period was extended and closed in February 2026. As of the end of July 2026 there is no final rule — the entire regulatory docket for that project consists of proposals.

So if you read that your insurer must now quote prices by phone: not yet. It is a proposal.[21, 22]

And one thing is open right now, which almost never happens while a guide is being read.

On July 7, 2026 CMS published its proposed outpatient payment rule for 2027, and inside it is a request for information on strengthening the standardization and comparability of hospital price transparency data. CMS is asking, in the open, how to handle the contract terms that still make files hard to read — outlier clauses, stop-loss provisions, tiering, carve-outs — and how to fix the payer and plan naming mess.

The comment period closes August 31, 2026. Anyone may comment, including a patient who spent an afternoon failing to find their plan in a spreadsheet. That is not a symbolic gesture; naming a specific, reproducible problem is exactly the input rulemaking runs on.

As for the Advanced Explanation of Benefits: still nothing. The enforcement pause announced in 2021 has never been lifted, and no rule has replaced it.[23, 41, 17]

Key Takeaways

The price is public, not secret. Every hospital must post its negotiated rates and its cash price online, free, with no account required. Your insurer must give you a personalized cost estimate on request for any covered service.

The footer link is the entrance. Scroll to the bottom of the hospital’s homepage and look for "price transparency" or "standard charges."

No code, no price. Ask the ordering doctor’s office for the exact CPT or HCPCS code and any modifier. Without it nothing is searchable.

January 1, 2026 made the files usable. Formula-based rates now have to show the 10th percentile, median and 90th percentile of what the hospital actually got paid, a named executive attests to the data, and enforcement began April 1, 2026.[1, 6, 26, 38]

The building matters more than the brand. The same code costs differently in a hospital outpatient department, an ambulatory surgery center, and a doctor’s office. Always ask which one you are being billed as.

Cash can be cheaper, and it has a hidden cost. Money paid outside your plan usually does not count toward your deductible or your out-of-pocket limit. Ask your plan before you pay, not after.

You can choose to be self-pay. Having coverage but not submitting the claim makes you a self-pay individual for that service under the regulation — which brings the written-estimate right with it.

An estimate is not an approval. Prior authorization, medical necessity, and separately billing clinicians are all outside the price you found.

Do not wait for enforcement. CMS has published 28 penalty notices in total. File a complaint if a hospital is out of compliance, then go get the number yourself.[13, 27, 32, 40]
