A computed tomography (CT) scan is one of the most common imaging tests ordered in the United States. Doctors use them to look at the head after a fall, the chest after a bad cough, the abdomen for unexplained pain, and the lungs to screen for cancer in long-term smokers. The scan itself takes a few minutes. The bill, however, can vary by more than 10x depending on where it gets done.
The same CT of the abdomen that runs $450 at an independent imaging center can be billed at $2,800 at a hospital outpatient department. Same machine technology, same radiologist often reading the images. Only the billing code and facility fee differ. Patients who need soft-tissue detail that a CT cannot provide should compare MRI costs, which use magnetic rather than radiation-based imaging.
This guide covers what a CT scan costs without insurance in 2026, what Medicare pays, why hospitals charge 2-3x more, common errors on a CT bill, and how prices differ for head, chest, and abdomen scans. Patients with high deductibles can often save hundreds by requesting the scan at a freestanding imaging center rather than a hospital. For bone density imaging, see the DEXA scan cost guide.
CT Scan Cost by Site of Service in 2026
The biggest cost driver of CT Scan is the site of service: where the procedure is performed. 2026 CMS price transparency data confirms a 2-3x billing differential between independent centers and hospital outpatient departments.
CT Scan prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Independent imaging center | $300 – $1,000 | $185 |
| Hospital outpatient department | $1,200 – $3,275 | $340 |
| Urgent care or freestanding ER | $800 – $2,500 | $340 |
| Inpatient hospital (during admission) | $1,500 – $4,500 | Bundled in DRG |

Why the Same Procedure Is So Much More at a Hospital
Hospitals bill CT scans at facility rates that include overhead, equipment depreciation, and staffing across the entire facility. Independent imaging centers run with much lower overhead and compete on price. The actual scan and image quality are identical at both. Only the billing code differs.
The difference shows up in what Medicare pays: the 2026 Physician Fee Schedule (PFS) pays approximately $185 for a typical outpatient CT performed at an independent center, while the Hospital Outpatient Prospective Payment System (OPPS) pays approximately $340 for the same scan done at a hospital. That gap gets magnified in cash prices, often 3-5x more at hospitals.
The practical takeaway: if your doctor orders a CT scan and the situation is not an emergency, an independent imaging center will usually save you $1,000 to $2,500.
CT Scan Cost by Body Part in 2026
Prices vary by what is being scanned. Head CTs are usually the cheapest because they are quick and rarely use contrast. Abdomen and pelvis scans tend to cost more, since they often include contrast and longer acquisition times. If your doctor orders contrast (a dye administered orally or intravenously), add $100 to $400.
Typical cost by variant| Body Part | Without-Insurance Range (no contrast) | With Contrast (add) |
|---|
| Head / Brain | $300 – $1,500 | +$100 – $300 |
| Sinus | $300 – $1,200 | +$100 – $250 |
| Chest / Lung | $400 – $2,200 | +$150 – $350 |
| Abdomen | $450 – $2,800 | +$200 – $400 |
| Pelvis | $450 – $2,800 | +$200 – $400 |
| Abdomen and pelvis (combined) | $700 – $3,275 | +$250 – $500 |
| Cervical spine | $400 – $2,000 | +$150 – $350 |
| Lumbar spine | $400 – $2,000 | +$150 – $350 |
| Coronary CT angiography | $500 – $2,500 | Included |
| Low-dose lung cancer screening | $100 – $400 | N/A |
Ranges assume mixed site of service. Ask your doctor whether contrast is actually needed before accepting it. Low-dose lung cancer screening is covered with no cost sharing under Medicare for eligible high-risk patients.

What Medicare Pays for CT Scan
In 2026, Medicare pays approximately $185 for a typical outpatient CT scan at an independent imaging center under the Physician Fee Schedule (PFS), and about $340 at a hospital outpatient department under OPPS. The specific amount depends on body part and contrast: a CT of the head without contrast is on the low end, a CT of the abdomen and pelvis with contrast is on the high end. Your share: 20% after meeting your 2026 Part B deductible of $283, unless you have a Medigap plan that covers coinsurance.
Medicare also covers annual low-dose CT (LDCT) lung cancer screening with no cost sharing for eligible beneficiaries ages 50 to 77 with a 20 pack-year smoking history who currently smoke or quit within the last 15 years. If you have Medicare Advantage, coverage rules vary by plan and most require prior authorization, with typical copays of $50 to $300 for a non-screening CT.
What Factors Affect Cost
- Site of service (hospital vs. independent imaging center), the biggest factor.
- With or without contrast dye (adds $100 to $400).
- Body part scanned (head is cheapest, abdomen and pelvis are highest).
- Number of regions scanned in one session.
- Geographic region (urban markets tend to be higher).
- Whether you have insurance and your deductible status.
- Whether the scan happens in the emergency department (ER scans add facility fees).
Common CT Scan Billing Errors
If your CT scan bill is well above the typical range, check for these errors before paying:
- Contrast billed when none was administered, or a higher tier of contrast billed than was used.
- Billed as two separate scans (abdomen and pelvis) when a combined abdomen-and-pelvis code applies.
- Hospital outpatient facility fee billed for a scan performed at an affiliated imaging center.
- Duplicate professional fees from two radiologists reading the same study.
- 3D reconstruction or post-processing billed separately when bundled into the main scan code.
- Low-dose lung cancer screening billed with patient cost sharing despite Medicare and ACA preventive coverage rules.
Frequently Asked Questions
How much does a CT scan cost without insurance in 2026?
Without insurance, a CT scan typically costs between $300 and $3,275 in 2026. The national median is around $1,200. Independent imaging centers charge $300 to $1,000, while hospital outpatient departments charge $1,200 to $3,275 for the same scan. Medicare pays approximately $185 for a typical outpatient CT at an independent center.
Why is the same CT scan so much more expensive at a hospital than an imaging center?
Hospitals bill CT scans at facility rates that include overhead, equipment, and staffing across the entire hospital. Independent imaging centers run with much lower overhead and compete directly on price. The scan and image quality are identical. Only the billing differs. The 2026 Medicare Outpatient PPS rate of about $340 at hospitals versus the Physician Fee Schedule rate of about $185 at independent centers shows how much site of service matters.
Can I get a CT scan without insurance?
Yes. Many independent imaging centers offer cash-pay rates of $300 to $700 for a CT scan without insurance. Some hospitals offer self-pay discounts of 20 to 50 percent off chargemaster prices, but you usually have to ask up front. Always request a written cash quote before scheduling and confirm whether the radiologist fee is included.
How much does Medicare pay for a CT scan?
In 2026, Medicare pays approximately $185 for a typical outpatient CT scan at an independent imaging center (Physician Fee Schedule rate) and about $340 at a hospital outpatient department (OPPS rate). You pay 20% after meeting your Part B deductible of $283 in 2026, unless you have a Medigap plan covering coinsurance. Low-dose lung cancer screening is covered at no cost for eligible beneficiaries.
What is the difference between a CT scan and an MRI in cost?
CT scans are generally cheaper than MRIs. A typical CT without insurance runs $300 to $3,275, with a national median around $1,200. A typical MRI runs $400 to $3,500, with a median around $1,325. CT scans are faster (a few minutes versus 30 to 60 minutes for MRI) and use lower-cost equipment, which is reflected in the price.
Does a CT scan with contrast cost more?
Yes. Contrast dye, administered orally or intravenously, adds $100 to $400 to a CT scan in 2026. The total cost depends on body part, contrast type, and site of service. Ask your doctor whether contrast is actually needed before accepting it, since some indications can be answered with a non-contrast study.
How do I dispute a CT scan bill?
Compare your bill line-by-line to the 2026 Medicare allowed amount for the body part scanned. If a charge is more than 2-3x the Medicare rate, you have leverage to dispute or negotiate. Common errors include contrast billed when none was used, abdomen and pelvis billed as separate scans when a combined code applies, or facility fees billed for scans done at an affiliated imaging center.
Is a CT scan cheaper at a freestanding imaging center than at a hospital?
Yes, almost always. Independent imaging centers charge $300 to $1,000 for a CT scan without insurance, compared to $1,200 to $3,275 at hospital outpatient departments. The 2026 CMS Hospital Price Transparency data and FAIR Health Consumer figures confirm this 2-3x markup at hospitals for the same scan.
