CT Scan Cost Without Insurance 2026: Real Prices

Your doctor says you need a CT scan. You call the hospital's radiology department, get transferred twice, and eventually someone tells you they can't quote a price until the claim processes. You don't have insurance. The claim isn't going to process.

Here's the number they didn't give you. A CT scan cost without insurance can be about $325 for an abdomen-and-pelvis study at a freestanding imaging center in most metro areas — and about $2,800 for the identical scan at the hospital three miles away. Same scanner technology. Same board-certified radiologist reading the images. The difference is entirely in how the building bills.

How much does a CT scan cost without insurance?

Self-pay CT prices in the US cluster between $250 and $3,500, and where you land inside that range has almost nothing to do with the scan itself.

You'll see "average CT scan cost" figures as high as $6,750 quoted around the internet. Those are billed charges — the list price a hospital sends an insurer before any discount, a number almost nobody actually pays. What matters to you is the facility's discounted cash price, which is a different number entirely and which most facilities will quote if you ask for it by name.

Where you get the scan	Typical self-pay price	What's driving it
Freestanding imaging center	$250 – $700	Low overhead, competes directly on price, usually quotes a bundled rate
Outpatient radiology clinic (hospital-affiliated)	$600 – $1,500	Mid-range, often adds a facility fee
Hospital outpatient department	$1,200 – $3,500	Facility fee plus separate radiologist billing
Emergency room	$3,000 – $9,000+	ER facility charge, physician charge, and imaging all bill separately

The spread between the top and bottom of that table is roughly ten to one. Very few purchases in American life have that kind of price variance for an identical product.

CT scan cost by body part and CPT code in 2026

Body part matters less than people expect. A head CT and a chest CT take similar scanner time. What actually moves the price is whether contrast is used, how many passes the protocol requires, and again — which building you're standing in.

Before you call a single facility, get the CPT code from your doctor's office. It's the five-digit billing code for your exact study, and without it you're comparing guesses. A center quoting "$400 for an abdominal CT" and one quoting "$900 for an abdominal CT" may be pricing completely different exams.

Scan	CPT code	Typical self-pay range
Head/brain, no contrast	70450	$250 – $900
Sinuses/maxillofacial, no contrast	70486	$250 – $800
Chest, no contrast	71250	$300 – $1,200
Chest CT angiogram (clot protocol)	71275	$600 – $2,500
Cervical spine (neck), no contrast	72125	$350 – $1,100
Lumbar spine (lower back), no contrast	72131	$350 – $1,100
Abdomen and pelvis, no contrast	74176	$325 – $1,400
Abdomen and pelvis, with contrast	74177	$400 – $1,800
Abdomen and pelvis, with and without	74178	$500 – $2,400
Coronary calcium score	75571	$99 – $400
Low-dose lung cancer screening	71271	$100 – $400

Low end of each range is a competitive freestanding center in a metro area with several of them. High end is a hospital-affiliated clinic. If you live somewhere with one imaging provider inside an hour's drive, expect to sit above these ranges — there's nobody to compete with.

Why the same scan costs $325 in one building and $2,800 in another

Every CT bill has two components, and knowing the difference is worth several hundred dollars.

The technical component pays for the scanner, the electricity, the technologist, and the room. The professional component pays the radiologist who reads your images and writes the report. A "global" rate covers both in one price.

Hospitals add a third charge: the facility fee. Hospital outpatient departments are licensed as part of the hospital, which carries real costs — 24-hour staffing, trauma readiness, care delivered to people who can't pay. Those costs get spread across every service the hospital bills, including a routine sinus CT that has nothing to do with any of it.

Freestanding imaging centers don't carry that overhead, and they run their machines closer to capacity. A modern 64-slice CT scanner costs roughly $600,000 to $1.5 million. Whether it does ten scans a day or thirty changes the arithmetic on every single one.

The second bill nobody warns you about

This is the trap. You call, get quoted $400, pay it at the desk, and feel like you handled it. Five weeks later an envelope arrives from a radiology group you've never heard of, asking for another $180.

That's the professional component. The imaging center quoted you the technical side and never mentioned the rest.

One sentence prevents it: "Is that a global rate that includes the radiologist's read and report, or will I receive a separate bill?"

Ask for the answer by email. If the facility won't put a global number in writing, you've learned something useful about how they'll handle your bill later.

What contrast adds to the price

Contrast is an iodine-based dye given by IV or by mouth that makes blood vessels, organs, and inflammation stand out. It adds roughly $75 to $300 to a CT — the agent itself, the IV placement, and the extra time.

There's a second, smaller cost most quotes leave out. Before IV contrast, many facilities check your kidney function with a creatinine or eGFR blood test, which runs about $10 to $40 self-pay if it isn't bundled. Ask whether it's included.

Whether you need contrast isn't a budget decision. If your order says "with and without," that's two full sets of images and a higher price, and there's usually a clinical reason for it. Ask your doctor, not the scheduler.

Contrast and your medications: the part nobody mentions

Cost guides skip this entirely, and it's the piece most likely to actually affect you on scan day.

If you take metformin. Iodinated contrast and metformin interact through the kidneys. If contrast temporarily reduces kidney function, metformin can accumulate and raise the risk of lactic acidosis. Current American College of Radiology guidance is reassuring for most people: if your eGFR is 30 or above and you have no acute kidney problem, you generally don't need to stop it. Below 30, or with acute kidney injury, the usual instruction is to hold metformin at the time of the scan and restart about 48 hours later once kidney function is rechecked. Tell the imaging center you take it when you book, not when you arrive. Metformin itself is inexpensive either way — about $52 for 100 tablets of the 500 mg through CanAmerica Plus.

If you've reacted to contrast before. Prior contrast reactions are handled with a premedication protocol, not by canceling the scan. The standard oral regimen is 50 mg of prednisone at 13 hours, 7 hours, and 1 hour before the scan, with 50 mg of diphenhydramine an hour beforehand. That's a 13-hour lead time, which means it has to be arranged in advance — showing up and mentioning it at the counter usually means rescheduling. Prednisone runs about $53 for 100 tablets through cash-pay channels, so this isn't the expensive part. The rescheduling is.

If you have kidney disease, are pregnant, or are breastfeeding. Say so when you book. All three change the protocol, and finding out on the table wastes a scan you already paid for.

How much does a CT scan cost with insurance?

With coverage, your cost depends on your deductible, your coinsurance, and whether the facility is in network. A CT ordered before you've met your deductible is often billed to you in full at the plan's negotiated rate — commonly $500 to $1,500 at a hospital outpatient department.

Most plans also require prior authorization for CT. Getting the scan without it is one of the more common ways insured patients end up owing the entire bill.

When paying cash beats using your insurance

Say you have a $6,500 deductible and you've spent nothing toward it. Your insurer's negotiated rate for CPT 74176 at the in-network hospital is $1,250. Because the deductible hasn't been met, that $1,250 is yours.

The freestanding center twenty minutes away charges $340 cash.

Paying cash saves you $910 today. The tradeoff: self-pay amounts usually don't count toward your deductible. If you're going to blow past it later this year anyway — a scheduled surgery, an ongoing condition — running the scan through insurance may still be the better move. Do the math on your actual year rather than the general rule.

The two CT scans insurance usually won't cover at all

For a couple of common scans, cash price isn't the backup option. It's the only price.

Coronary calcium scoring (CPT 75571) measures calcified plaque in your heart arteries and gives a number that meaningfully refines cardiovascular risk. Most insurers don't cover it as preventive care, so nearly everyone pays out of pocket — typically $99 to $400, and many hospital systems run promotional pricing closer to $99. If you're weighing whether to start a statin, this is one of the better $150 you can spend on your own health information.

Low-dose CT lung cancer screening (CPT 71271) is different: it carries a Grade B recommendation from the US Preventive Services Task Force for adults 50 to 80 with a 20 pack-year smoking history who currently smoke or quit within the past 15 years. ACA-compliant plans have to cover it with no cost sharing if you meet those criteria. If you don't meet them, or you're uninsured, self-pay is usually $100 to $400.

How to find the cheapest CT scan near you

Sequence matters here.

1. Get the CPT code and contrast instructions from your doctor's office. One phone call. Everything downstream depends on it.
2. List every accredited facility within a reasonable drive. The American College of Radiology publishes a searchable directory of accredited imaging sites. Widen the radius — a 45-minute drive to save $1,100 is excellent pay.
3. Look the price up before you call. Federal price transparency rules require hospitals to publish standard charges, including discounted cash prices, in a machine-readable file plus a consumer display of shoppable services. Search the hospital's name and "price transparency" and you can often find the cash price for your code without talking to anyone.
4. Call at least three and ask the same three questions. What's your self-pay rate for CPT [code]? Does that include the radiologist's read? What's the prompt-pay discount?
5. Ask about the prompt-pay discount explicitly. Many centers take 20% to 40% off for payment at the time of service. It's almost never advertised. It's frequently available.
6. Request a written good-faith estimate. Since January 2022, the No Surprises Act has entitled uninsured and self-pay patients to one before a scheduled service. If the final bill lands $400 or more above the estimate, you can challenge it through the federal patient-provider dispute resolution process. Facilities know this, which tends to produce more careful quotes.

Three calls usually surface a several-hundred-dollar spread. Sometimes a four-figure one.

What the scan finds is often the bigger bill

The CT is one charge. What it turns up can be a monthly charge for years, and that's the part worth pricing before you're committed to it.

Kidney stones. A non-contrast CT of the abdomen and pelvis is the standard test, and most stones pass with fluids and pain control. Cheap answer, cheap follow-up.

A pulmonary embolism. A CT angiogram of the chest that finds a clot puts you on an anticoagulant for at least three to six months, sometimes indefinitely. This is where US retail pricing gets painful. Eliquis carries a US reference price around $1,561 for a 180-tablet supply; through CanAmerica Plus it's about $200, and the generic apixaban runs about $130. Xarelto is roughly $195 for 100 tablets against a US reference above $835, with generic rivaroxaban near $110 for 120. Which one you're on is your doctor's call. What you pay for it is not.

Diverticulitis or an intra-abdominal infection. Usually a course of oral antibiotics — often ciprofloxacin with metronidazole, around $83 and $55 respectively for 100 tablets through cash-pay channels. Short course, modest money.

None of this is a reason to skip a scan your doctor ordered. It's a reason to treat the scan as the start of a cost conversation instead of the end of one.

CT scan vs MRI: which is cheaper?

CT is usually cheaper. It's also faster — a CT takes 5 to 15 minutes against 30 to 60 for an MRI — which is part of why it costs less to deliver.

But the two aren't interchangeable. CT is better for bone, acute bleeding, kidney stones, and lung tissue. MRI is better for soft tissue: ligaments, cartilage, spinal cord, brain detail, many tumors. Swapping one for the other to save $200 is how people end up paying for both. If cost is genuinely the obstacle, say that to your doctor plainly — they may have a clinical reason the specific test matters, or they may agree an ultrasound answers the question well enough. Our breakdown of MRI costs without insurance covers the other side of that comparison in detail.

There's one more difference worth knowing. CT uses ionizing radiation; MRI doesn't. A head CT delivers roughly 2 mSv, a chest CT about 7 mSv, and an abdomen-and-pelvis CT around 10 mSv, against about 0.1 mSv for a chest X-ray. The risk from any single scan is small and almost always outweighed by the diagnostic benefit. It's still a reason not to collect repeat scans casually, and a reason to bring prior images with you rather than let a new facility re-scan you from scratch.

The bottom line

CT scan cost without insurance is decided far more by which building you walk into than by what's being scanned. Get the CPT code, look up the hospital's published cash price, call three accredited facilities, confirm the quote is a global rate, and ask for the prompt-pay discount and a written good-faith estimate.

Then price the thing the scan leads to. If it puts you on a long-term prescription, check what that medication costs through CanAmerica Plus before you fill it the first time. And if you're still deciding where to be seen at all, our guide to urgent care costs without insurance covers the front end of the same problem.

Frequently asked questions

Can I pay out of pocket for a CT scan?

Yes, and you'll often pay less than an insured patient with an unmet deductible. Ask specifically for the "self-pay" or "discounted cash price" rather than the standard rate. Most freestanding imaging centers quote a bundled cash price on the phone, and many take an additional 20% to 40% off if you pay at the time of service.

How much does a CT scan cost in the ER?

Substantially more — commonly $3,000 to $9,000 once the emergency facility fee, the ER physician charge, and the imaging itself are added together. If your symptoms aren't an emergency, getting the scan ordered as an outpatient study is the single largest cost decision you'll make. If they are an emergency, go to the ER anyway and sort out the bill afterward.

Why won't the hospital tell me what a CT scan costs?

Front-line staff often genuinely don't know, because their systems are built to bill insurers rather than quote patients. Ask for the billing or patient financial services department by name and request the discounted cash price for your specific CPT code. Federal price transparency rules also require hospitals to publish those prices online, so you can often find the number yourself before calling.

How long does it take to get CT scan results?

A radiologist typically reads the images within 24 to 48 hours, and your ordering doctor reviews the report before contacting you. In an emergency room, results usually come back within an hour. If you're paying cash, confirm who will call you with results and how — some freestanding centers send the report to the ordering physician only.

Is a CT scan or a CAT scan different?

They're the same test. CAT stands for computed axial tomography, the original name; CT is the modern shorthand for computed tomography. If a facility quotes a "CAT scan" price, you're being quoted for the same study.
