Knee MRI Cost After a Premium Hike: $450 at an Imaging Center vs $2,400 at a Hospital on a $7,500 Deductible Bronze Plan (or Going Uninsured)
Your doctor says you need a knee MRI. Your premium just went up by a few hundred dollars a month, your deductible is high, and you are wondering whether it's worth having insurance at all. Before you schedule anything, here is the question that decides most of your bill: which facility, and where are you in your deductible?
That question matters more than most people realize. Below I model one knee MRI under three situations: a Bronze-style high-deductible plan with the deductible unmet, the same plan with the deductible met, and no insurance at all.
Why this question is coming up in 2026
KFF Health News recently reported on Joshua and Ashley Durham in Idaho. Their health insurance premiums rose by hundreds of dollars a month this year. They are healthcare practitioners who understand the risks better than most, and they still chose to go uninsured. The story notes that others can't afford to go without coverage.
Notice what that story is not about. It is not about people who don't understand insurance. It is about people who did the math and found the monthly premium hard to justify. The system priced them into a gamble, and that's not their fault.
If you're in a similar spot, or you moved to a cheaper Bronze plan to hold premiums down, the price you pay for each service now matters much more. On a high-deductible plan you are effectively the buyer for most of what you get in the first part of the year.
A note on the numbers below: they are modeling inputs I chose to illustrate how the math works. They are not quotes from a specific hospital or plan. Your local prices, plan design, and allowed amounts will differ, which is exactly why you should check them.
The setup: one knee MRI, two facilities
Let's use CPT 73721 (MRI of a lower extremity joint without contrast, the standard knee MRI). Here are the assumptions:
- Independent imaging center: in-network allowed amount of $450. Cash price about $400.
- Hospital outpatient department: in-network allowed amount of $2,400. Chargemaster (list) price of $4,200.
- Plan: Bronze-style, $7,500 deductible, 30% coinsurance after the deductible.
- Premium: $650/month ($7,800/year) for one adult.
The "allowed amount" is the price your insurer has agreed to with that facility. It's not the list price on the bill, and it's not what the insurer pays. Your deductible and coinsurance are calculated off the allowed amount. If those terms are new, my post on deductible, coinsurance, and EOB decoded after an MRI walks through them line by line.
Scenario 1: Deductible not met (January to spring)
You haven't spent anything toward your $7,500 deductible yet.
| Facility | Allowed amount | Deductible applied | Coinsurance | You owe |
|---|---|---|---|---|
| Imaging center | $450 | $450 | $0 | $450 |
| Hospital outpatient | $2,400 | $2,400 | $0 | $2,400 |
Same scan, same knee, a $1,950 difference. Neither bill triggers coinsurance because you're still inside the deductible. Every dollar is yours.
Now look at what the difference does to your deductible. The hospital scan uses up $2,400 of it. The imaging center scan uses $450. Spending more doesn't help you if you were never going to hit the deductible anyway, which is true for many people who are healthy most of the year.
Scenario 2: Deductible already met (say, after a surgery earlier in the year)
Now imagine you've already paid the full $7,500 and coinsurance applies:
| Facility | Allowed amount | 30% coinsurance | You owe |
|---|---|---|---|
| Imaging center | $450 | $135 | $135 |
| Hospital outpatient | $2,400 | $720 | $720 |
The gap shrinks to $585, but the ratio is still more than 5 to 1. Compare the two scenarios: the imaging center scan with an unmet deductible ($450) is still cheaper than the hospital scan with a fully met deductible ($720). Waiting until December to schedule at the more expensive facility doesn't beat picking the cheaper facility today.
This breaks the common advice to "schedule after you've hit your deductible." That's true when the two facilities are priced the same. It's not true when the price spread is bigger than the deductible discount.
Scenario 3: You're uninsured
This is where the Durhams' choice comes in. Without a plan, there's no allowed amount. You get whatever price the facility offers you.
| Facility | What you might be quoted | Notes |
|---|---|---|
| Imaging center, cash price | ~$400 | Often a flat posted self-pay rate |
| Hospital, chargemaster rate | $4,200 | The full list price, if no discount is applied |
| Hospital, after financial assistance | $0 to a fraction of the bill | Depends on the hospital's policy and your income |
Uninsured at the imaging center, you pay about $50 less than the insured Bronze patient with an unmet deductible ($400 vs $450). Uninsured at the hospital with no discount, you pay $1,800 more than the insured patient's allowed amount ($4,200 vs $2,400).
That's the hidden cost of being uninsured at the wrong facility. If you go without a plan, the facility you choose becomes the whole ballgame. I cover the cash-pay route in detail in how to pay $350 for an MRI instead of $4,800 without insurance.
This is the kind of side-by-side Privenox runs for you, so you don't have to build the spreadsheet yourself.
The real trade-off: premiums vs. what insurance protects you from
An MRI is the small version of this decision. The bigger question the Durhams faced is whether $7,800 a year in premiums is worth paying when you might spend only a few hundred dollars on care.
Here is the math on a plain year with a knee MRI and nothing else major:
| Bronze plan | Uninsured | |
|---|---|---|
| Premiums | $7,800 | $0 |
| Knee MRI at imaging center | $450 | $400 |
| Total | $8,250 | $400 |
That's a $7,850 gap in a quiet year. This is why people go without coverage. It's rational on the numbers, when the year is quiet.
Now take a bad year: a hospitalization with a $60,000 chargemaster total.
- Bronze plan: the insurer's allowed amount comes in around $20,000. You pay the $7,500 deductible plus 30% of the remaining $12,500 ($3,750), which totals $11,250. But your plan's out-of-pocket maximum caps what you pay. If that cap is $10,600 in this example, you pay $10,600, plus $7,800 in premiums, for $18,400 total.
- Uninsured: you start from the $60,000 list price. What you actually pay depends on negotiation, cash-pay discounts, and financial assistance. It could be far lower than $60,000, but it's uncertain and it's your job to work it out.
This is not a recommendation either way. Whether to carry coverage is a personal decision that depends on your health, your savings, and your risk tolerance, and I'm not the person to make it for you. What the math shows is that the two years look completely different, and that the price of individual services swings your quiet-year cost far more than most people expect.
For how bills escalate in the bad-year scenario, see what an allowed amount really means on a $58,000 ER bill.
The five-facility shopping model
Say you look up prices at five facilities near you. Here are hypothetical in-network allowed amounts for the same knee MRI:
| Facility | Allowed amount |
|---|---|
| Independent imaging center A | $450 |
| Independent imaging center B | $620 |
| Outpatient clinic | $1,100 |
| Hospital outpatient department A | $2,400 |
| Hospital outpatient department B | $3,100 |
The average is $1,534. If you book with no comparison and land at a random one, your expected cost with an unmet deductible is about $1,534. If you book the cheapest, you pay $450, saving $1,084 versus the average and $2,650 versus the most expensive.
A spread like this is not unusual. In the same ZIP code, one CPT code can carry a 5x to 10x range. Our own analysis of 16,357 data points across six sources, including the cms-fee-schedule dataset (5,700 rows drawn from the Medicare Physician Fee Schedule), gives us a Medicare benchmark to measure private prices against. Medicare payment for a given code is a fixed national schedule adjusted by region. Private prices at your local facilities can sit well above or close to that benchmark, and the difference is the part you can shop.
Why the hospital price is often higher for the same scan
Part of the reason is the facility fee. When an MRI is billed as a hospital outpatient service, the hospital charges for the use of the facility on top of the professional reading. The identical scanner in a freestanding center bills less overhead. I explain the mechanics in why MRI costs $400 at an imaging center and $4,200 at a hospital that acquired your doctor's practice.
You are not being told the wrong price on purpose by a doctor. Many patients just never see the price until the EOB arrives. That's the system hiding the number, not the patient failing to ask.
What the 340B charity care report means for your bill
Healthcare Dive reported on a new analysis finding that 340B hospitals lag behind their peers in charity care spending. The 340B program lets eligible hospitals buy outpatient drugs at steep discounts, and critics say the program has ballooned. The report gives them more ammunition.
I'll stay in my lane on the policy fight. Here's what it means practically for you:
- Don't assume a big hospital has a generous financial assistance policy. Being a nonprofit, or a 340B participant, doesn't guarantee that the hospital's charity care actually reaches patients.
- Read the policy before you're billed. Federal rules require nonprofit hospitals to have a written financial assistance policy. Income thresholds differ widely by hospital.
- Ask for it early. If you're uninsured or facing a large unmet deductible, ask the billing office for the financial assistance application before the scan, not after the bill hits collections.
A state investigation into how hospitals set those thresholds is in this charity care breakdown. And for the step-by-step of asking for a discount, see how to pay $400 for an MRI that costs $3,500 at the hospital.
Your personal variables: a checklist before you schedule
The best option isn't the same for everyone. Here's how each of your variables changes the answer.
1. Plan type and deductible. A $7,500 deductible makes almost every service full-price for you until you hit it. A $1,500 deductible changes how much the facility gap costs you in coinsurance. Our aca-marketplace-premiums dataset (3,060 rows drawn from CMS public-use files) shows how much plan premiums and cost-sharing tiers vary by metal level, and the kff-insurance-benchmarks dataset (200 rows) gives employer-plan deductible benchmarks to compare against. Your own plan documents have the exact numbers.
2. Deductible status today. Check your insurer's portal for how much you've paid so far. If you're close to meeting it, the gap between facilities narrows, but it seldom closes.
3. Location. Facility prices differ widely by market. Consolidated hospital systems tend to have higher negotiated rates. The census-acs-health-context dataset (6,286 rows) shows how coverage and income mix vary by area, which is part of why the same procedure has a different local price picture in Boise than in Nashville.
4. Procedure. An MRI is easy to shop because it's scheduled and routine. An emergency isn't. If your care is planned, you have time to compare. If it's urgent, ask about the facility fee and out-of-network risk as soon as it's safe to do so.
5. Ordering doctor's network. If your doctor's practice has been bought by a hospital, the order may default to the hospital's imaging department. You can generally ask for the order to be sent elsewhere. This is a billing and logistics question, not a medical one, so ask your doctor's office which in-network options they can send it to.
Questions to ask before you book
Call each facility and ask:
- "What is the price for CPT 73721 for someone with my plan?" (Give them your plan and member ID.)
- "Is that a facility fee plus a separate radiologist fee, or one bill?"
- "If I pay cash, what is the self-pay price?"
- "Do you have a financial assistance policy, and can I get the application now?"
Write down the name of who quoted you, and the date. If the final bill is different, that note matters.
What I'd want you to take away
The Durhams' story shows the pressure premiums put on people, including people who know the healthcare system well. Whether you carry coverage, drop it, or switch to a Bronze plan, the same fact holds: on a high-deductible plan or no plan, you're paying the facility's price yourself. A $1,950 gap on a single knee MRI is real money, and it's decided by where you book, not by how sick you are or how well you understand your insurance.
You can model this for your specific situation at Privenox: plug in your plan's deductible, where you are in the year, and the facilities near you, and compare what each option costs you before you schedule.
Check prices before you book. It takes a few phone calls, and it can be the difference between a $450 bill and a $2,400 one.
