Hospital Posts $1,400 MRI Price Under CMS Rules — Then the Radiologist Bills $680 Separately: What Price Transparency Laws Actually Cover in 2026
Your doctor orders a brain MRI. You pull up your hospital's price transparency file — the one they're legally required to post under CMS rules — and you find the number: $1,400 negotiated facility rate with your insurer. You budget. You schedule. You show up, get scanned, and go home feeling like the rare patient who had their financial ducks in a row.
Six weeks later, two bills arrive. The hospital bill is exactly what you expected: $1,400 facility charge, $280 applied to your deductible, $168 in coinsurance. Then there's the second bill — from a radiology group you've never heard of — for $680. Nobody mentioned that part.
This isn't a billing error. It's a structural gap between what CMS price transparency rules require hospitals to disclose and what the system at large allows everyone else to hide. Understanding that gap before you schedule is the difference between budgeting $448 and actually owing $1,128 for the exact same scan.
What the CMS Transparency Rule Actually Covers
Beginning in 2021, CMS required every hospital in the United States to publish a machine-readable file listing their standard charges — including negotiated rates with individual insurers — for all services. Enforcement escalated to fines of up to $2 million per year for non-compliant hospitals. This is a genuine, hard-won consumer protection.
Privenox's analysis of our cms-fee-schedule dataset (5,700 rows across procedures and geographies) shows facility rates for a standard brain MRI with contrast (CPT 70553) ranging from $680 to $6,200 across hospitals nationally — a 9x spread for the identical procedure. That spread is only visible because the transparency rule forced hospitals to publish it.
But here is the limitation buried in the fine print: the rule covers the facility. It does not cover the physician.
When you have an MRI, two separate providers bill you:
- The hospital or imaging center (facility fee) — covered by the CMS transparency rule
- The radiologist who interprets the scan (professional fee) — billed by an independent physician group operating under their own tax ID, governed by no equivalent disclosure requirement
Based on Privenox's cms-fee-schedule analysis, the Medicare-allowed amount for radiologist interpretation of a brain MRI (CPT 70553, professional component) runs approximately $95 to $140. Commercial insurer rates typically run 3–5x Medicare — meaning the professional fee alone could add $280 to $680 on top of whatever facility rate your transparency file showed. You won't know the number until the Explanation of Benefits (EOB) arrives weeks after your appointment.
This is the kind of analysis Privenox runs for you — pulling both the facility rate and the likely professional fee from transparency filings, so the number you're budgeting against is the full bill, not half of it.
The Physician Debt Lawsuit Problem
This billing gap isn't just a budgeting inconvenience. KFF Health News's reporting on Connecticut's medical debt landscape reveals something that should change how every patient thinks about an unexpected physician bill: in Connecticut, doctors and dentists are now more likely to sue patients over unpaid medical debt than hospitals are.
Hospitals face growing public pressure, state legislation, and IRS nonprofit compliance requirements that have pushed many large systems to expand charity care and limit aggressive collections. Physician groups and dental practices operate under no such constraints. They're private businesses with no charity care mandate, no CMS disclosure requirement, and increasing willingness to use civil courts to collect balances.
The sequence plays out like this: you paid the hospital bill because you knew about it. The radiologist's $680 bill arrived, looked like another EOB, got set aside, and sat unpaid for 90 days. Now it's in collections — or a judgment. The price transparency rule told you about the facility. Nobody told you about the radiologist.
As we covered in our analysis of how physicians are driving medical debt lawsuits and what it means for your radiology bills, this pattern is accelerating nationally — and the No Surprises Act, for all its promise, has specific carve-outs that leave scheduled physician billing largely unaddressed.
What the No Surprises Act Did — and Didn't Do
The No Surprises Act (effective January 2022) targeted the most egregious version of surprise billing: out-of-network providers at in-network facilities. If you go to an in-network hospital and an out-of-network anesthesiologist is involuntarily assigned to your surgery, the Act limits what that physician can bill you to your in-network cost-sharing amount.
But the Act has hard scope limits:
- It applies when the out-of-network provider is involuntarily assigned — it does not cover cases where you theoretically could have chosen your own providers
- It does not require advance disclosure of the professional fee amount — only that a separate fee may exist
- Ground ambulances are explicitly excluded
- Scheduled outpatient imaging sits in a compliance gray zone that varies by plan and state
The practical result: the radiologist reading your MRI may be in-network and still bill at a rate that produces a larger cost-sharing obligation than anything in the hospital's transparency file. Your EOB will eventually show you the "allowed amount" — the discounted rate your insurer negotiated — but that number only appears after the procedure is done.
If you haven't decoded what "allowed amount," "coinsurance," and "applied to deductible" actually mean on your EOB, this walkthrough of what you owe after an MRI translates the jargon into plain math.
The Medigap Layer: Premium Hikes That Widen the Exposure Window
Now layer in the Medigap situation for Medicare beneficiaries. KFF Health News's recent report on Medigap premiums documents rates leaping 15–20% in a single year at multiple insurers, with consumers facing few alternatives in markets with limited competition.
Medigap (Medicare Supplement Insurance) fills the gaps traditional Medicare leaves open: the Part A deductible ($1,676 in 2026), the Part B 20% coinsurance with no annual out-of-pocket cap, and the Part B deductible ($257 in 2026). Without Medigap, a Medicare beneficiary's cost exposure on the same brain MRI scenario looks like this:
| Service | Medicare Allowed | Medicare Pays (80%) | You Pay (20%) |
|---|---|---|---|
| Hospital facility fee, MRI brain (CPT 70553) | $950 | $760 | $190 |
| Radiologist professional read | $130 | $104 | $26 |
| Subtotal | $216 |
That looks manageable in isolation. But the 20% with no cap compounds quickly: add a follow-up PET scan, a specialist consultation, and one short hospitalization, and a Medicare beneficiary without supplemental coverage can face $3,000–$6,000 in Part B coinsurance in a single year — all stemming from physician and facility fees that were never fully disclosed before any single appointment.
Medigap Plan G eliminates nearly all of that exposure for a premium of roughly $150–$230/month depending on age and state. But a 15–20% rate hike adds $270–$552 annually — and for Medicare enrollees on fixed incomes, the "is this premium still worth it?" math just got harder. We modeled the break-even calculation in detail in our post on Medigap Plan G costs and what you'll pay for a colonoscopy or knee MRI without it.
The Real Math: Three Scenarios, Same MRI, Wildly Different Bills
Let's run the same brain MRI (CPT 70553) through three insurance situations using Privenox's aca-marketplace-premiums dataset (3,060 rows) and cms-fee-schedule data. Hospital negotiated facility rate: $1,400. Radiologist professional fee: $520 (in-network, separate group).
Scenario A — ACA Silver Plan, $3,500 deductible, deductible not yet met
| Component | Allowed | You Pay |
|---|---|---|
| Hospital facility | $1,400 | $1,400 |
| Radiologist professional | $520 | $520 |
| Total out-of-pocket | $1,920 |
You pay 100% of both allowed amounts because your deductible is untouched. The transparency file showed you $1,400. Your actual bill is $1,920.
Scenario B — Same ACA Silver Plan, deductible already met, 30% coinsurance
| Component | Allowed | Your 30% |
|---|---|---|
| Hospital facility | $1,400 | $420 |
| Radiologist professional | $520 | $156 |
| Total out-of-pocket | $576 |
Identical procedure, identical providers. You save $1,344 by being later in the calendar year.
Scenario C — Medicare + Medigap Plan G
| Component | Amount |
|---|---|
| Part B deductible (already met) | $0 |
| 20% coinsurance on facility + professional | Covered by Plan G |
| Total out-of-pocket | $0 |
The same MRI costs $1,920, $576, or $0 — based entirely on your plan, your deductible timing, and whether Medigap fills the gap. You can model this for your actual deductible level, coinsurance rate, and procedure cost at Privenox.
The Facility Price Spread the Rule Doesn't Advertise
All three scenarios above assumed a hospital-based imaging center at $1,400 for the facility component. But that's a variable — and it's one you can control before you schedule.
Privenox's cms-fee-schedule analysis of brain MRI facility rates across a typical metro area shows:
| Facility Type | Typical Negotiated Rate Range |
|---|---|
| Academic medical center | $1,800 – $6,200 |
| Hospital-based imaging center | $1,100 – $4,200 |
| Freestanding imaging center (chain) | $400 – $900 |
| Freestanding imaging center (independent) | $350 – $750 |
Choosing a freestanding center at $500 instead of the hospital at $1,400 — when your deductible isn't met — means $900 stays in your pocket with no change in clinical outcome. The imaging equipment is often identical. The radiologist may be the same person, reading remotely. The difference is the facility fee, and the facility fee is posted in a transparency file you can access right now. Our breakdown of how to use CMS price transparency rules to find the cheaper MRI facility on an HDHP walks through exactly how to read those files.
What to Ask Before You Schedule Anything
The system will not hand you a complete, pre-procedure cost estimate voluntarily. But you can build one yourself if you ask the right questions:
Before booking:
- Ask your insurer for the negotiated rate for the specific CPT code at the facility you're considering — not the chargemaster rate, the allowed amount
- Ask the facility: "Does a separate physician group interpret this scan? Are they in-network with my plan?"
- Search the hospital's CMS transparency file for your CPT code — it's required to be there by law
- Compare at least one freestanding imaging center rate against the hospital rate for the same CPT
If you're on Medicare: 5. Run the 20% coinsurance math across every procedure you expect this year — not just the one you're scheduling 6. Factor in the current Medigap premium after any rate increase when calculating break-even
If an unexpected physician bill arrives: 7. Don't let it age past 60 days — physician groups are collecting more aggressively and filing suits at higher rates than hospitals 8. Call the billing office, confirm the allowed amount matches your EOB, and ask about payment plans before the bill moves to collections
The price transparency rules that CMS has built are a real foundation — but they cover one layer of a multi-layer billing system. The hospital rate is posted. The physician rate isn't. The interaction between your deductible status, your coinsurance rate, and both fees determines what you actually owe. None of that math is done for you automatically.
Privenox is built to close that gap — pulling the facility rate, modeling the likely professional fee, and calculating your real out-of-pocket across multiple providers near you, before you commit to scheduling. The data exists. Someone just has to decode it for you.
