Why is a CT scan cheaper at an imaging center than a hospital?

Free-standing imaging centers do not charge the facility fee that hospital outpatient departments add, and they are reimbursed at a lower rate. For a routine outpatient CT, that makes the imaging center substantially cheaper for the identical study — often two to three times less.

Does a CT scan with contrast cost more?

Yes. Adding intravenous or oral contrast moves the scan into a higher billing code and increases the price. Some studies are performed both with and without contrast in one session, which costs more again. Whether contrast is needed is a clinical decision made by the ordering physician and radiologist.

Does insurance cover a CT scan?

Yes, for medically necessary scans, but non-emergency CTs almost always require prior authorization. Without prior auth on file at the time of service, your insurer can deny the claim and leave you owing the full billed amount. Confirm prior authorization before you schedule.

What is the difference between a CT scan and an MRI in cost?

CT and MRI are priced through the same structure (technical fee plus radiologist read, with a facility fee at hospitals), but MRI is generally the more expensive of the two for comparable body areas. The choice between them is clinical, not financial — they image different things — but for cost the same rules apply: imaging center beats hospital, and prior auth matters.

How much does a CT scan cost?

Nationally, hospitals in the cleartau dataset publish an average cash price of $2,793 for CT abdomen and pelvis across 3,304 hospitals with cash prices. Published cash prices range from $28 to $38,136, with a median around $2,053.

CT scan prices depend on body area, contrast, radiologist interpretation, emergency department setting, and separate professional fees.

Data last refreshed: May 28, 2026

CT (CAT) scan prices in hospital transparency files span a wide range — commonly a few hundred dollars at a free-standing imaging center to several thousand at a hospital outpatient department for the same body area, with contrast studies costing more than non-contrast. As with MRI, the published median for a routine scan is far lower than the chargemaster 'gross' price, and what you actually pay depends heavily on where the scan is done and whether you have insurance.

A CT scan bill has the same two-part structure as most imaging: a technical/facility component for performing the scan and a professional component for the radiologist who reads it. Hospital outpatient departments add a facility fee that free-standing imaging centers do not, which is the main reason the same CT can cost two or three times as much across the street. Body area and contrast then move the price within that range.

This guide aggregates hospital-published CT prices and is reference data, not a personal estimate. If a CT has been ordered for you on a non-emergency basis, the highest-leverage step is to compare the specific body area at an imaging center versus a hospital, and to confirm prior authorization with your insurer before scheduling.

What affects the price

Body area: CT of the head, chest, abdomen/pelvis, and extremities are billed under different CPT code groups with different reference rates. Abdomen-and-pelvis studies (often ordered together) and multi-region scans cost more than a single-region scan such as a head CT.
Contrast: Adding intravenous or oral contrast moves the study into a higher billing code and typically adds to the price. Whether contrast is needed is a clinical decision; both with- and without-contrast versions are billed differently, and some studies are done both ways in one sitting (higher cost).
Setting: imaging center vs. hospital outpatient department: A free-standing imaging center bills as a single entity with no separate facility fee and is reimbursed at a lower rate than a hospital outpatient department. For the identical scan, the imaging center is usually substantially cheaper — frequently the largest single factor in the final price.
Facility fee vs. radiologist fee: The transparency-file price is usually the technical/facility component. The radiologist who interprets the scan bills a separate professional fee, sometimes weeks later and occasionally from an out-of-network practice even when the facility is in-network.
Emergency department setting: A CT done during an ER visit is billed at ER rates and bundled into the much larger emergency-visit bill. The same scan obtained on an outpatient basis is almost always cheaper, which is one reason non-emergency imaging should not be done in the ER if it can be scheduled.

Cost without insurance

Free-standing imaging centers are usually the best option for cash-pay CT scans, often advertising bundled prices that include both the scan and the read well below hospital outpatient department cash rates. National cash-pay imaging marketplaces and local imaging center websites are worth comparing.

If you must use a hospital, call the billing office for the self-pay rate rather than the chargemaster price, and ask whether it includes the radiologist read or whether that arrives as a separate bill. Nonprofit hospitals are required to offer financial assistance to qualifying patients.

Ask whether contrast is necessary — a non-contrast study, when clinically appropriate, is cheaper — and get any cash-pay discount in writing before the scan.

Cost with insurance

With insurance, you owe the negotiated rate applied against your deductible and coinsurance. Non-emergency CT scans almost always require prior authorization; without it on file at the time of service, the claim can be denied and you can be billed the full amount. Confirm prior auth before scheduling.

If your plan covers both settings, choosing a free-standing imaging center over a hospital outpatient department lowers the negotiated rate and therefore your share. Some insurers actively steer members to lower-cost imaging sites and will tell you where.

The radiologist who reads the scan can be out-of-network even at an in-network facility. The No Surprises Act generally protects you from balance billing for such ancillary services at in-network facilities — flag any surprise read fee to your insurer.

How to pay less

Use a free-standing imaging center rather than a hospital outpatient department when your insurance allows it — this is usually the biggest single saving.

Ask for the cash-pay price even if you have insurance; under a high-deductible plan it sometimes beats the negotiated rate plus coinsurance (though it will not count toward your deductible).

Confirm prior authorization is on file before the scan, and ask whether contrast is clinically necessary.

Get a bundled quote that states whether the radiologist read is included, and confirm the reading radiologist is in-network.

Frequently asked questions

How much does a CT scan cost?: Published prices commonly range from a few hundred dollars at a free-standing imaging center to several thousand at a hospital outpatient department for the same body area, with contrast studies costing more.
