Does Medicare cover it?
Does Medicare cover an MRI?
Yes. Part B covers an MRI when your doctor or another provider orders it to find or treat a medical problem. Where the scan is done changes your bill more than anything else, so the estimator prices it both at an imaging center and in a hospital outpatient department.
What this service costs you
You pay
$187
| Medicare-approved amount | $187 |
| Part B deductible used | $187 |
| Deductible left after this | $96 |
Part B: you pay the yearly deductible ($283 in 2026), then 20% of the approved amount.
Same service at national rates: $192
How this is calculatedMedicare Part B covers diagnostic tests such as MRI scans when a doctor or other health care provider orders them to find or treat a medical problem. In a doctor's office or an independent diagnostic testing facility, you pay 20% of the Medicare-approved amount after the $283 Part B deductible, and the facility must be accredited for advanced imaging, or Medicare will not pay. At national 2026 rates an MRI of the lower back without contrast is approved $192 at such a center, so your share is $38 once the deductible is met; a brain MRI comes to $39. If the scan is your first Part B bill of the year, the deductible takes the whole amount and the lower back MRI costs you $192. In a hospital outpatient department the bill splits in two, the radiologist's reading and the hospital's fee, and you pay the hospital a copayment that can be more than 20% but in most cases not more than the Part A deductible. The same lower back MRI there is approved $312 and leaves you $62. If an imaging center is not accredited and Medicare refuses the claim for that reason, the provider cannot bill you for the test.

Costs computed by Radif Partners · Editorial policy · How the costs are calculated
When Medicare pays for the scan
Medicare groups MRI with the other diagnostic tests that are not lab work, such as CT scans, X-rays, EKGs and PET scans. Part B covers them when your provider orders them to find or treat a medical problem, in other words to rule an illness in or out. An MRI requested without such an order, as a general check, does not meet that condition.
Prices for three common scans
The table gives the national 2026 approved amounts for scans without contrast. At an office or imaging center, a single global fee covers the images and the radiologist's reading. In a hospital outpatient department, the reading is billed by the radiologist and the hospital charges its own rate for the scan.
| MRI, national rates | Imaging center: approved | You pay | Hospital outpatient: approved | You pay |
|---|---|---|---|---|
| Brain, without contrast | $195 | $39 | $312 | $62 |
| Lower back, without contrast | $192 | $38 | $312 | $62 |
| Knee, without contrast | $204 | $41 | $307 | $61 |
The hospital share includes a copayment set for the imaging service. Medicare notes that this copayment may be more than 20% of the approved amount, and that in most cases it cannot exceed the Part A hospital deductible, $1,736 in 2026. For an MRI the copayment stays far below that ceiling, but it is still larger than what you pay at an imaging center.
The deductible and the timing of the scan
When the MRI is your first Part B service of the year, the $283 deductible is paid first. A lower back MRI at an imaging center is approved for less than the deductible, so you pay its full $192. In a hospital the deductible is used up and the copayment applies on the rest: $289 for the same scan, against $62 later in the year.
Accreditation outside the hospital
For advanced imaging, meaning CT, MRI, nuclear medicine and PET, done outside a hospital, whether by a provider, a medical practice, a clinic or a free-standing radiology center, Medicare pays only if the provider is accredited. Check before the appointment. If Medicare refuses to pay for your test because the provider is not accredited, the provider cannot bill you for it.

Local prices and other coverage
The office fee follows the local cost index of the physician fee schedule. A lower back MRI at an imaging center leaves you $44 in Manhattan and $35 in Alabama, against $38 at national rates, with the deductible met. Choose your state and price area in the estimator for your own figure.
Medigap Plan G pays the 20% and the hospital copayment once the deductible is met, which leaves nothing for a scan later in the year. A Medicare Advantage plan sets its own imaging copay; enter your plan's figures in the estimator. Hospitals now publish their standard charges, including those negotiated with Advantage plans, on a public website, which can help when you compare places.
