Per scan is a billing term that means your insurance charges you a flat fee for each imaging test, regardless of how many images the technician takes

When your doctor orders an X-ray, MRI, CT scan, or ultrasound, your insurance company decides how much it will pay the imaging center and how much you will pay out of pocket. A per scan charge is one way they structure that cost — you pay one fixed amount per test, not per image or per body part scanned. If you get one MRI of your knee, you pay one per-scan fee. If you get an MRI of your knee and your shoulder on the same day, you typically pay two per-scan fees.

This matters because it affects what you owe before you even walk into the imaging center. Understanding the difference between per-scan charges and other billing methods helps you predict your bill and know whether to ask questions before the appointment.

Key Takeaways

  • A per-scan charge is a single flat fee your insurance requires you to pay for each imaging test, regardless of how many pictures are taken.
  • Per-scan fees are different from per-image fees (charged for each individual picture) and from copays (a fixed amount for any office visit or procedure).
  • Your insurance plan documents or your insurance card usually lists what your per-scan cost is, or you can call your insurance company to ask.
  • If you have multiple imaging tests on the same day, you will typically owe one per-scan fee for each test, not one fee total.
  • Asking your imaging center or insurance company about per-scan charges before your appointment helps you budget and avoid surprise bills.

How per-scan charges differ from other imaging costs

Insurance companies use several ways to charge for imaging. Understanding which one applies to you prevents confusion at the billing desk. A per-scan fee covers the entire test — one ultrasound, one X-ray, one MRI — no matter how many images the technician captures. You pay once per test.

A per-image fee charges you for each individual picture taken during the test. If a technician takes 15 X-rays of your chest, you might pay per image rather than per scan. This method is less common in modern plans but still exists in some older insurance policies.

A copay is a fixed dollar amount you pay for a category of care — for example, $50 for any imaging procedure. Copays do not change based on what type of imaging you get or how many images are taken. A coinsurance charge means you pay a percentage of the cost (like 20%) after your deductible is met, rather than a flat fee.

Your plan may also use a combination: you might have a $50 copay for imaging plus a per-scan charge on top of that, depending on your specific policy.

Where to find your per-scan cost

Your per-scan fee should appear in your insurance plan documents, usually in a section labeled "Imaging," "Diagnostic Services," or "Radiology." If you have your insurance card, the back often lists a customer service number you can call to ask directly.

When you call, tell the representative the type of imaging you need — for example, "I need an MRI of my knee" — and ask what your out-of-pocket cost will be. They can tell you whether you have a per-scan fee, a copay, coinsurance, or a combination. They can also tell you whether you have met your deductible for the year, which affects what you owe.

You can also ask the imaging center itself before your appointment. Call the radiology department or billing office and give them your insurance information. They often know what your plan charges and can give you an estimate. This is especially useful if you are going to an imaging center outside your insurance network, where costs may be higher.

What happens when you have multiple scans on the same day

If your doctor orders two different imaging tests on the same day — for example, an X-ray and an ultrasound — you typically owe one per-scan fee for each test. You would pay one fee for the X-ray and one fee for the ultrasound, for a total of two per-scan charges.

However, some insurance plans have a daily maximum or a rule that caps your out-of-pocket cost if you have multiple tests in one visit. Before your appointment, ask your insurance company whether there is a limit to how much you will owe if you have more than one imaging test that day. This information can change your budget significantly.

If your doctor orders multiple images of the same area — for example, three different angles of your knee on one X-ray visit — that is still one scan and one per-scan fee. The number of images within a single test does not increase your cost under a per-scan model.

Per-scan fees and your deductible

Your per-scan charge may or may not count toward your annual deductible, depending on your plan. Some plans require you to meet your deductible before insurance starts paying for imaging, which means you pay the full cost of the scan yourself until the deductible is reached. Other plans cover imaging even before the deductible is met.

When you call your insurance company to ask about your per-scan cost, also ask whether imaging counts toward your deductible and whether you have already met it this year. If you have not met your deductible, you may owe more than the per-scan fee alone — you might owe the full cost of the imaging until your deductible is satisfied.

Once your deductible is met, your per-scan fee is what you owe (unless your plan also has coinsurance, in which case you pay a percentage of the cost after the per-scan fee).

Out-of-network imaging and per-scan charges

If you go to an imaging center that is not in your insurance network, per-scan charges may be higher or work differently. Out-of-network providers can charge more, and your insurance may pay less toward the cost, leaving you with a larger bill.

Before scheduling imaging at an out-of-network center, call your insurance company and ask what your out-of-pocket cost will be. Ask whether the per-scan fee is the same as in-network, or whether you will owe a higher percentage of the cost. Some plans do not cover out-of-network imaging at all, or cover it only in emergencies.

Whenever possible, use an in-network imaging center to keep your per-scan cost predictable and lower.

What to do if you receive a bill higher than expected

If your imaging bill is higher than the per-scan fee your insurance company quoted, review the bill carefully. Check whether you were charged per scan, per image, or both. Look for separate line items for the technician, the radiologist, the facility, or the equipment — sometimes these are billed separately and add to your total cost.

If the bill does not match what you were told, call your insurance company first and ask them to review it. Then contact the imaging center's billing department and ask for an itemized bill that explains every charge. If there is a mistake, ask the imaging center to correct it and resubmit to your insurance.

If you cannot afford the bill, ask the imaging center whether they offer a payment plan. Many centers will let you pay in installments rather than in full upfront.

Frequently Asked Questions

Does per scan mean I pay for each body part, or each test?

Per scan means each test. If your doctor orders one MRI that images your knee, you pay one per-scan fee. If the technician takes 50 images of that knee during the test, you still pay one per-scan fee. If you have an MRI of your knee and a separate MRI of your shoulder, that is two tests and two per-scan fees.

Is a per-scan fee the same as a copay?

Not always. A copay is a fixed amount for a category of care, while a per-scan fee is specific to imaging. Some plans have both — you might pay a $50 copay for imaging plus a per-scan fee on top of that. Check your plan documents or call your insurance company to see which applies to you.

What if I do not know my per-scan cost before my appointment?

Call your insurance company's customer service line (the number is on your card) and tell them the type of imaging you need. They can tell you your out-of-pocket cost and whether your deductible affects it. You can also call the imaging center and give them your insurance information — they often know what your plan charges.

Do I have to pay the per-scan fee upfront, or can I pay after?

This varies by imaging center. Some collect payment before the test, some bill you afterward, and some ask for payment at the time of service. Call the imaging center ahead of time and ask about their payment process so you are not surprised on the day of your appointment.

Can my per-scan cost change from year to year?

Yes. Insurance plans change their costs and coverage every year, usually in January. If you had imaging last year, your per-scan fee this year may be different. Check your new plan documents or call your insurance company to confirm your current per-scan cost.
