What Will My MRI Cost? $0 to $4,200 Depending on Your Deductible, State, and Charity Care Rules

Your doctor says you need a knee MRI. Four people in the same ZIP code get the same order: CPT 73721, an MRI of a lower-extremity joint without contrast. A few weeks later, their bills look like this:

Patient A owes $0.
Patient B owes $400.
Patient C owes $1,900.
Patient D holds a statement for $4,200.

Same scan. Same body part. Nobody did anything wrong. The difference came from four variables: where they booked, what plan they have, how much deductible was left, and which state they live in. None of those are printed on the order your doctor handed you.

This post walks through how each variable changes the number. The dollar figures here are illustrative of the spread we see. Your plan's allowed amounts will differ, and that's the point of this post: the right answer depends on your inputs, so you need to check prices at your own local facilities before you schedule.

What this week's KFF Health News coverage means for your bill

The week's health-policy coverage was heavy, and most of it won't change what an MRI costs you this month.

KFF Health News's "Midterms Have Revived Universal Healthcare Debate. These States Are Ahead of Everyone." describes candidates floating a restoration of federal ACA subsidies and Medicaid funding. It also describes Oregon officials drafting a plan for universal coverage in their state. Whatever you think of these proposals, they will take time, and your MRI is probably being scheduled in weeks.

Another KFF Health News piece, "Rural MAHA Followers Say Trump Health Policies Haven't Reached Their Communities," reports on a KFF-Associated Press survey of rural voters. The finding is that sweeping national initiatives often aren't reaching local communities yet. The KFF Health News on-air roundup from October 3 touches on the same poll. For a patient, the lesson is the same: prices are set locally, one facility at a time, no matter what Washington or your state capital is debating.

Then there's the story that's hard to read. KFF Health News's "Patient Dies by Suicide After 'Insurance Issue' Delayed Medicine for Lung Disease Flare-Ups" describes a Texas man whose prescription sat unfilled because of an "insurance issue." It's a reminder that coverage friction has human stakes beyond dollars. The system makes it too hard to find out in advance what will be covered, what it will cost, and who to call when something stalls. If you're stuck at a pharmacy counter, ask exactly what the issue is and call your doctor's office the same day. If you or someone you know is struggling, you can call or text 988 anytime.

The article most useful for your wallet is "Hospitals Have a Little-Known Tool To Prevent Medical Debt. Here's How It Works." It's about presumptive eligibility for charity care, and we'll get to it below.

The price spread for CPT 73721: one scan, a 10x range

Based on Privenox's analysis of 16,357 data points across six public sources, the pattern holds across procedures. The facility you choose moves your bill far more than the procedure does. Here's the knee MRI spread:

Where the scan happens	What you might see	What it means
Medicare benchmark (our cms-fee-schedule dataset, 5,700 rows from the Medicare Physician Fee Schedule)	A few hundred dollars	The government's own price for the work
Independent imaging center, cash price	$400	Often a flat, all-in price
Independent imaging center, insurance allowed amount	$350–$600	What your insurer agrees to pay (the "allowed amount")
Hospital outpatient department, insurance allowed amount	$1,200–$1,900	Includes a hospital facility fee
Hospital chargemaster (list price)	$4,200	The sticker price, which almost nobody with insurance actually pays

That's more than a 10x spread between $400 and $4,200, and the Medicare benchmark shows the $4,200 is a list price, not a cost.

Facility fee is the term to know. When a scan is billed as a hospital outpatient service, you can get a technical "facility" charge for the room, machine, and overhead. A separate bill from the radiologist who reads the images can follow. A freestanding imaging center usually bundles this into one lower price. For more on how this plays out, see our breakdown of MRI costs at an imaging center versus a hospital that just acquired your doctor's practice.

Hospitals are supposed to publish these prices under CMS rules, but the files are hard to read. Our guide to reading a hospital's CMS-required price file shows what to look for. This is also the kind of comparison Privenox runs for you, so you don't have to dig through a spreadsheet with millions of rows.

Worked example: same plan, three patients, three bills

Take one plan: a $4,000 deductible and 20% coinsurance. The deductible is what you pay before insurance starts sharing costs. Coinsurance is your percentage of the bill after that. We'll use $400 as the imaging center's allowed amount and $1,900 as the hospital's.

Patient 1: deductible untouched ($0 met). You pay the full allowed amount until you hit $4,000.

Imaging center: $400
Hospital: $1,900
Shopping saves $1,500.

Patient 2: deductible fully met. You pay only coinsurance.

Imaging center: 20% of $400 = $80
Hospital: 20% of $1,900 = $380
Shopping saves $300.

Patient 3: partway through, with $3,600 of the $4,000 already met. You owe the last $400 of deductible, then 20% of the rest.

Imaging center: $400 (all of it goes to the remaining deductible)
Hospital: $400 + 20% × ($1,900 − $400) = $400 + $300 = $700
Shopping saves $300.

The same $1,500 gap in sticker prices becomes a $1,500 difference to you or a $300 one, depending on where you are in your year. Deductible status resets every January and changes every time you use care. That's why a price list alone can't answer "what will I pay?"

For a wider look at this, see our post on MRI cost at $1,500, $4,000, and $7,500 deductibles. You can run these numbers for your own plan at Privenox.

When shopping saves $1,500, $300, or $0

Say you're also expecting a $15,000 (allowed amount) surgery in December. Same plan: $4,000 deductible, 20% coinsurance, and an $8,000 out-of-pocket maximum. The out-of-pocket maximum is the most you'd pay in a year for covered in-network care. Does the MRI price still matter?

Path 1: hospital MRI at $1,900

MRI: $1,900 (all counts toward deductible)
Surgery: remaining deductible $2,100 + 20% × $12,900 = $2,100 + $2,580 = $4,680
Year total: $6,580

Path 2: imaging center MRI at $400, billed through insurance

MRI: $400
Surgery: remaining deductible $3,600 + 20% × $11,400 = $3,600 + $2,280 = $5,880
Year total: $6,280

Shopping saved $300 here, not $1,500. Because you're going to blow through the deductible anyway, most of the MRI savings is just pushing dollars around inside the same year.

Now a wrinkle. Say you paid the imaging center $400 cash, outside your insurance. In many plans, that payment does not count toward your deductible:

MRI: $400 cash
Surgery: $4,000 deductible + 20% × $11,000 = $4,000 + $2,200 = $6,200
Year total: $6,600

That's slightly worse than the hospital path ($6,580), even though the scan was $1,500 cheaper. If you expect to hit your deductible this year, ask the imaging center whether it can bill your insurance at a similar rate. Also ask your plan whether cash payments count, since some states and plans credit them.

If a big claim would push you to your $8,000 out-of-pocket maximum no matter what, the MRI price difference to you can shrink to $0. If you're early in the year, uninsured, or on a plan where you pay the deductible mostly out of pocket, shopping can save you the full $1,500.

Charity care you may not have to apply for

Patients D and A at the top of this post differ in one way. Patient A lives in a state with a presumptive eligibility rule. Patient D doesn't.

Hospital financial assistance (charity care) can cut a bill sharply or to zero, but traditionally you have to find the policy and fill out a long form with pay stubs. KFF Health News's explainer, "Hospitals Have a Little-Known Tool To Prevent Medical Debt. Here's How It Works," covers the alternative. Some states now require hospitals to identify patients likely to qualify and enroll them automatically, using information they already have. That's presumptive eligibility.

In plain English: instead of you proving you're poor enough to deserve help, the hospital checks first. If you live in a state with that rule, a $4,200 list price may never turn into a collections letter. If you don't, the same bill can sit unopened while a patient who qualifies doesn't know to ask. You can read more in our post on presumptive charity care for a CPT 73721 knee MRI bill. We also covered why thresholds vary from hospital to hospital in a state investigation.

Where you live matters more than most people expect. Census ACS data in our health-context dataset (6,286 rows) puts the national uninsured rate at roughly 8%. By state it runs from under 3% in Massachusetts to roughly 16% in Texas. The rules, safety nets, and price norms around you are shaped by that.

Rural? Your shopping math changes

The KFF-AP rural poll is a reminder that "just go somewhere cheaper" assumes there's somewhere else to go. In rural areas, the in-network hospital may be your only option within 40 miles.

Here, drive time becomes a variable. If the cheaper imaging center is 60 miles away and saves $1,500 (the unmet-deductible case), it's worth a tank of gas. If it saves $300 (the deductible-met case), you might stay local and use other levers:

Ask for the cash or self-pay price, which is sometimes lower than the insurance rate.
Request the hospital's financial assistance application before the scan, not after the bill.
Ask whether the scan can be done at an outpatient site not billed as a hospital department.

Our guide to cash pay, charity care, and bill negotiation for a $400 vs $3,500 MRI walks through these steps.

Why your plan type makes the gap bigger in 2026

Plan design is pushing more of the price onto you. In our aca-marketplace-premiums dataset (3,060 rows built from CMS marketplace public-use files), premiums vary a lot by county and age. KFF estimated that average benchmark silver premiums rose about 26% for 2026 after the enhanced subsidies lapsed. Many people responded by moving to bronze plans, where deductibles often reach $7,000 or more.

In our kff-insurance-benchmarks dataset (200 rows from KFF's Employer Health Benefits Survey), employer-plan deductibles for single coverage have averaged roughly $1,800 to $1,900 in recent years. The BLS medical CPI series (1,080 rows) shows hospital prices rising faster than general consumer prices over the long run. And in our healthcare-defaults data, hospital care accounts for just under a third of national health spending, so the stakes of the facility you choose are large.

A bigger deductible means more of the $400 vs $1,900 gap lands on you directly. Our post on what a bronze plan means for an MRI, colonoscopy, or outpatient surgery goes deeper.

Your variables, your best option

Your situation	What usually matters most	Likely best move
Deductible mostly unmet, in-network imaging center available	Allowed-amount gap	Book the imaging center, billed through insurance
Deductible met, or you'll hit the out-of-pocket max this year	Coinsurance only (or $0 difference)	Choose on convenience and quality; confirm in-network
Uninsured or very high deductible	Cash price vs chargemaster	Ask for cash price in writing; check charity care first
Lower income, state with presumptive eligibility	Hospital's assistance policy	Ask whether you've been screened before you pay anything
Rural, one in-network hospital	Distance vs savings	Negotiate, ask for assistance forms, and compare a farther center
Planning a big procedure later this year	Whether cash payments count toward your deductible	Ask the center to bill insurance, or confirm your plan credits cash

Five things to look up before you schedule

Get the CPT code. Ask your doctor's office for it (73721 for this knee MRI) so that every quote is for the same service.
Ask each facility for the total. Request the all-in price including the facility fee and the radiologist's read, not just "the scan."
Check your deductible and out-of-pocket status. Your insurer's portal shows how much you've met so far this year.
Confirm network status in writing. Some imaging centers are in-network and some aren't.
Ask about financial assistance or presumptive eligibility. Ask before the scan, not after the bill.

None of that is medical advice, and your doctor decides what scan you need. These steps only cover which door you walk through to get it. Patients shouldn't have to do detective work for a basic price. The system hides it behind chargemasters, allowed amounts, and deductible math, and that's why we built a tool for the job.

Check before you book

Policy debates in Oregon, Washington, and the midterms may change coverage over time. Your MRI price is being set today, by a facility within 15 miles of you, based on your plan and your deductible.

Before you schedule, compare what your local facilities charge for the exact CPT code, with your own deductible and your own state's rules in the math. You can do that at Privenox. Enter your procedure, your plan details, and your location, and see what you'd actually owe at each option, before you agree to anything.
