Computed tomography scans are among the most frequently ordered diagnostic tests in the United States, with roughly 90 million performed each year according to the National Institute of Biomedical Imaging and Bioengineering. Despite how common they are, the CT scan cost remains surprisingly opaque for most patients. Prices range from as little as $250 to well over $3,000, and the amount you pay depends on whether you have insurance, the body part being scanned, and where the test is performed.
Average CT Scan Cost in 2026
Without insurance, the typical CT scan cost falls between $300 and $3,000. With insurance, most patients pay between $50 and $600 out of pocket after copays and coinsurance. Here is a breakdown of common CT scans and their approximate price ranges without coverage:
- Head/brain CT: $300 – $2,000
- Chest CT: $350 – $2,500
- Abdominal CT: $400 – $2,800
- Abdominal and pelvic CT: $500 – $3,000
- Spinal CT: $350 – $2,500
- CT angiography: $500 – $3,500
- Sinus CT: $250 – $1,500
These ranges include both the technical fee (facility and equipment) and the professional fee (radiologist interpretation). Adding contrast dye — an iodine-based liquid injected intravenously to highlight blood vessels and organs — typically adds $100 to $400 to the total.
CT Scan Cost With Insurance
If you have private insurance, your out-of-pocket cost for a CT scan depends on your plan’s deductible, copay, and coinsurance structure. Patients who have not yet met their annual deductible will owe the full negotiated rate, which is usually 40 to 60 percent below the list price. Once the deductible is satisfied, you typically owe a copay of $50 to $200 or coinsurance of 10 to 30 percent.
Medicare Part B covers medically necessary CT scans at 80 percent of the Medicare-approved amount after the annual deductible. According to Medicare.gov, the Medicare-approved amount for an abdominal CT without contrast is roughly $240 to $600 depending on the facility type and geographic region. Beneficiaries owe the remaining 20 percent — typically $50 to $120.
Medicaid generally covers CT scans with little to no patient cost-sharing, though prior authorization requirements vary by state. Always verify coverage before your appointment to avoid surprise bills.
CT Scan Cost Without Insurance
Uninsured patients face the widest price swings because they are typically billed at or near the facility’s chargemaster rate. Hospital outpatient departments charge the most — often $1,500 to $3,000 for a routine abdominal CT. Freestanding imaging centers, by contrast, frequently offer the same scan for $300 to $800.
The CT scan cost also varies by urgency. An emergency room CT performed during an acute visit can cost $2,000 to $5,000 once ER facility fees are added. If your situation is not emergent, scheduling the scan at an outpatient facility on a non-urgent basis will almost always be cheaper. Of course, if you are experiencing symptoms that may require emergency care for abdominal pain, do not delay treatment to save money.
Factors That Influence CT Scan Pricing
Understanding what drives cost variation helps you make smarter choices about where and when to get scanned.
Facility Type
Hospital-based imaging departments charge facility fees that freestanding centers do not. This single factor can double or triple the price for the same scan on the same machine. According to a CMS analysis, hospital outpatient CT scans cost Medicare 40 to 80 percent more than the same scans at ambulatory centers.
Body Part and Complexity
A simple sinus CT involves a narrow field of view and no contrast, keeping costs low. An abdominal and pelvic CT with contrast, by comparison, requires more machine time, contrast material, and a more complex radiologist interpretation — all of which increase the price.
Contrast Dye
Scans performed with intravenous contrast cost $100 to $400 more than those without. Your doctor orders contrast when they need to visualize blood vessels, detect tumors, or evaluate organ perfusion. This is a clinical decision, not something you can opt out of to save money.
Geography
CT scan prices in high-cost metro areas like New York, Boston, and San Francisco can run 50 to 100 percent above the national median. Patients in the Midwest and South generally find the lowest prices.
How to Save Money on a CT Scan
Price shopping for a CT scan is one of the most effective ways to reduce your healthcare spending, because the quality difference between a $400 scan and a $2,500 scan is usually nonexistent.
Choose a freestanding imaging center. Independent radiology facilities offer the lowest prices and the same equipment found in hospitals. Many advertise all-inclusive cash-pay rates on their websites.
Use price transparency tools. Federal price transparency rules require hospitals to publish their negotiated rates. Consumer tools built on this data — along with platforms like Sesame and MDsave — let you compare CT scan prices by ZIP code and body part.
Ask for the self-pay discount. Most facilities offer a reduced rate for patients who pay out of pocket. Discounts of 25 to 50 percent off the list price are typical. Request the discount before the scan, and ask for the total bundled price including the radiologist fee.
Check for financial assistance. Nonprofit hospitals must offer charity care programs. If your income qualifies, you may receive a substantial reduction or full waiver of your CT scan cost.
Use your HSA or FSA. Health savings and flexible spending account funds can be used tax-free for CT scans, effectively saving you 20 to 35 percent depending on your tax bracket.

CT Scan vs. MRI: When Each Is Used
Patients sometimes wonder whether they need a CT scan or an MRI. The two tests serve different purposes. CT scans excel at imaging bone, detecting bleeding, evaluating lung conditions, and diagnosing abdominal emergencies. They are fast — usually completed in less than 10 minutes — which is why they are the go-to test in emergency departments.
MRIs, on the other hand, provide superior soft-tissue detail and are better for evaluating ligaments, tendons, brain tissue, and spinal discs. They take 30 to 60 minutes and cost more on average. Your physician selects the appropriate test based on the clinical question, not price, but knowing the cost difference can help you prepare financially.
Frequently Asked Questions
How much does a CT scan cost at an emergency room vs. an outpatient center?
An ER CT scan typically costs $2,000 to $5,000 because of added emergency facility fees. The same scan at a freestanding outpatient imaging center usually costs $300 to $800. If your condition is not an emergency, scheduling at an outpatient facility saves significantly.
Does insurance cover all CT scans?
Most insurance plans cover CT scans that are deemed medically necessary by your doctor. However, you may still owe a copay, coinsurance, or deductible payment. Preventive screening CTs, such as low-dose lung cancer screening, are covered without cost-sharing for eligible patients under ACA rules.
Is a CT scan with contrast more expensive?
Yes. Adding contrast dye increases the CT scan cost by $100 to $400, covering the cost of the contrast material, the IV supplies, and the additional time required for the procedure. Your doctor orders contrast only when it is clinically necessary to answer the diagnostic question.
Can I get a CT scan without a doctor’s order?
In most states, a CT scan requires a physician’s order. Some direct-to-consumer imaging companies offer self-referred scans for cash, but insurance will not cover them without a medical order. If cost is a concern, consider a telehealth consultation to obtain a referral affordably.
The Bottom Line
The CT scan cost ranges from around $250 for a simple sinus scan at an imaging center to over $3,000 for a complex hospital-based exam. Choosing a freestanding facility, requesting the self-pay rate, and using price comparison tools are the most reliable ways to lower your bill. Whether you have insurance or not, understanding these pricing dynamics puts you in control of one of the most common — and most variable — healthcare expenses you are likely to encounter.
