Quick answer: The same MRI or CT scan often costs two to four times more at a hospital outpatient department than at an independent imaging center. The main reason is the facility fee: hospitals bill a separate charge for the building, staff and overhead, and Medicare and insurers pay hospital outpatient departments higher rates for the same service. The scanner, the technologist and the radiologist’s training can be the same. For many routine, scheduled scans, an accredited independent center is a safe way to pay less. For some patients and exams, the hospital is the better choice.
Same scan, different price: a typical example
| Exam (self-pay, 2026) | Independent imaging center | Hospital outpatient department |
|---|---|---|
| MRI brain, without contrast | $400–$900 | $1,500–$3,500 |
| CT abdomen and pelvis, without contrast | $400–$900 | $1,500–$3,500 |
| FDG PET/CT | $1,300–$2,500 | $3,000–$6,000 |
| Abdominal ultrasound | $100–$450 | $400–$1,000 |

How hospital imaging is billed
Every imaging exam has two parts:
- The technical component: the scanner, the technologist, supplies and the room.
- The professional component: the radiologist’s reading and report.
An independent imaging center usually bills both parts together as one global fee, under Medicare’s physician fee schedule.
A hospital outpatient department bills the technical part as a facility charge, under Medicare’s hospital outpatient payment system, which pays higher rates. The radiologist then bills separately. That’s why a hospital scan often produces two bills, and with Medicare, you may owe two copays.
Why hospitals charge more
Hospitals say their higher rates reflect real costs that independent centers don’t carry:
- They keep scanners and staff available 24/7 for emergencies.
- They care for sicker and more complex patients, including inpatients and people who need sedation or close monitoring.
- They must meet additional regulatory requirements and often serve patients who can’t pay.
Critics, including many health policy researchers and some lawmakers, point out that for a routine, scheduled outpatient scan, the service is the same, so the payment should be too. This idea is called site-neutral payment.
«Hospital-owned» doesn’t always look like a hospital
Many clinics and imaging centers are owned by a hospital system and bill as a hospital outpatient department, even if they’re in an office park miles away from the hospital. The sign may say «imaging center,» but the bill includes a facility fee.
Before you book, ask: «Do you bill as a hospital outpatient department, or as an independent facility? Will there be a facility fee?»
What’s changing
- Medicare site-neutral payments. Since 2019, Medicare has paid many off-campus hospital clinic visits at a lower, site-neutral rate, and it extended this to drug administration in 2026. For 2027, CMS has proposed paying off-campus hospital outpatient departments about 60% less for imaging without contrast, such as X-rays and many MRIs. Rural hospitals would largely be excluded. This is a proposal, not a final rule.
- State laws. About 18 states have laws on facility fees. Most require hospitals to tell patients about facility fees in advance or show them clearly on bills; a few restrict them for certain services.
Is the quality the same?
Often, yes. What matters most is accreditation and equipment, not the building.
- Accreditation: Independent centers that bill Medicare for MRI, CT, nuclear medicine and PET must be accredited by a CMS-approved organization, such as the American College of Radiology (ACR). Look for the ACR gold seal.
- Mammography: Every facility, hospital or not, must be certified by the FDA under the Mammography Quality Standards Act.
- Equipment: Ask about the scanner. For example, field strength for MRI (1.5T or 3T) or whether they offer 3D mammography.
- Who reads it: Ask whether a board-certified radiologist, ideally a subspecialist, reads your images.
When the hospital may be the better choice
- Emergencies. Go to the emergency room. Don’t shop for price.
- You need sedation or anesthesia, or you have serious heart, lung or kidney problems.
- Your exam is part of a biopsy or procedure, or a specialized test only the hospital offers.
- You need pediatric imaging with a team experienced with children.
- Your care team needs the images the same day, or you’re already a hospital inpatient.
- Your insurance only covers the hospital in your area or pays it at a better in-network rate.
How to find out what you’ll pay
- Ask how the site bills (hospital outpatient or independent) and whether there’s a facility fee.
- Get the CPT code for your exam and ask both sites for a price.
- Check your insurer’s cost estimator. With insurance, a hospital can sometimes be cheaper if it has a better negotiated rate.
- Ask your doctor if the order can go to an accredited independent center, if it’s appropriate for your care.
- If you’re uninsured or self-pay, ask for a Good Faith Estimate.

Tips from the technologist
- Don’t judge by the sign on the door. Ask about billing.
- Take your images with you. Whichever site you use, ask for portal access or a disc so your doctors can compare later.
- Choose consistency for follow-ups. For cancer surveillance or tracking a finding, using the same site and scanner makes comparison easier. Discuss this with your doctor before switching to save money.
FAQ
What is a hospital facility fee?
A separate charge a hospital adds for the use of its facility, equipment and staff when you’re seen in a hospital outpatient department. It’s billed in addition to the doctor’s fee.
Why did I get two bills for one scan?
In a hospital setting, the hospital bills for the scan (facility) and the radiology group bills for the reading. Independent centers often bill both in one.
Are independent imaging centers safe?
Yes, when they’re accredited. Medicare requires accreditation for independent centers that perform MRI, CT, nuclear medicine and PET, and all mammography facilities must be FDA-certified.
Is a hospital always more expensive?
For cash prices, usually. With insurance, not always: your plan’s negotiated rate with each site decides. Check your insurer’s estimator.
Can I ask my doctor to send my order elsewhere?
Yes. You can ask, and many doctors will agree for routine scans. Your doctor may have medical reasons to prefer a specific site.
