Quick Answer: A brain MRI (CPT 70553) costs $320 to $330 at Medicare rates but $1,000 to $14,000+ at hospital chargemaster prices. A lumbar spine MRI (CPT 72148) runs $145 to $550 in Medicare or negotiated rates but appears as $600 to $3,500 on a typical hospital bill. The gap between what hospitals charge and what they actually accept is one of the most reliable signs of billing error or overcharge in American healthcare.
The price of an MRI in 2026 depends almost entirely on who is paying, not what the scan actually costs. The same 30-minute procedure in the same machine can generate a bill for $400 at a freestanding imaging center or $14,000 at a hospital outpatient department two miles away. Neither number reflects what Medicare actually reimburses, what your insurer negotiates, or what you should accept on a self-pay basis.
Understanding the three-tier price system behind MRI billing (chargemaster rates, negotiated rates, and Medicare reimbursement) is the difference between paying a bill and fighting one.
What the CPT Codes Actually Describe
Before comparing prices, it helps to know what you are paying for.
CPT 70553 covers an MRI of the brain with and without contrast. This is the code you see when a neurologist orders a brain scan that requires a gadolinium injection mid-scan to highlight blood vessels, tumors, or inflammatory tissue. It is a more complex scan than a basic brain MRI and therefore carries a higher billing rate.
CPT 72148 covers an MRI of the lumbar spine without contrast. This is the most commonly ordered spine MRI in the United States, used routinely for back pain, herniated discs, sciatica, and spinal stenosis evaluation. Because it requires no contrast agent, it is faster and less expensive to perform.
Both codes appear on hospital bills, insurance EOBs (Explanations of Benefits), and Medicare remittance notices. If your bill shows either code, the Medicare rate is the most reliable public benchmark you have for what the procedure is actually worth.
The Three-Tier MRI Pricing System
Tier 1: Chargemaster (List) Price
The chargemaster is a hospital's internal price list, a number that exists primarily as a negotiating anchor with insurance companies. It is not what most patients pay, but it is what an uninsured or out-of-network patient gets billed by default.
For CPT 70553 (brain MRI with/without contrast), chargemaster prices at U.S. hospitals range from roughly $1,000 to $18,000 for the same exact scan. Research analyzing federal price transparency files from 274 hospitals across 46 states found the median cash price for a brain MRI around $2,200, with outliers well above $10,000.
For CPT 72148 (lumbar spine MRI without contrast), chargemaster prices typically run $600 to $3,500 at hospital outpatient departments, with freestanding imaging centers charging $400 to $900 for the same procedure.
Hospitals price MRIs this high because they can. Insurance contracts historically paid facility fees on top of scan fees for hospital-based outpatient services, and self-pay patients often accepted whatever appeared on the bill.
Tier 2: Medicare Reimbursement Rate
Medicare sets a national reimbursement schedule based on the actual resources required to perform each procedure: physician time, clinical staff, equipment, and overhead. These rates are the closest thing to a fair market price for medical services that exists in the U.S.
As of 2026:
| CPT Code | Procedure | Medicare Rate (Non-Facility) | Medicare Rate (Facility/Hospital) |
|---|
| 70553 | Brain MRI w/wo contrast | $320 to $330 | ~$290 (via APC) |
| 72148 | Lumbar spine MRI w/o contrast | $188 to $204 | $145 to $165 |
The non-facility rate applies when the scan is performed at a freestanding imaging center. The facility rate applies to hospital outpatient departments, where additional facility fees can dramatically increase the total bill even when the professional fee is lower.
A 2025 study in Academic Radiology tracking Medicare reimbursement trends from 2003 to 2025 found that imaging reimbursements have been cut repeatedly over two decades while hospital costs have continued rising, meaning the gap between chargemaster prices and Medicare rates has grown wider each year.
Tier 3: Negotiated (Insured) Rate
If you have private insurance, your insurer has a contracted rate with the hospital or imaging center. This rate typically falls between the Medicare rate and the chargemaster price.
Research published in Health Affairs found that hospitals' cash prices average 60% higher than negotiated rates, while list (chargemaster) prices average 164% higher than what insurers actually pay.
For a practical reference point:
| Setting | CPT 70553 (Brain MRI) | CPT 72148 (Lumbar Spine MRI) |
|---|
| Medicare rate (non-facility) | $320 to $330 | $188 to $205 |
| Commercial insurer negotiated | $450 to $900 | $275 to $550 |
| Cash pay (hospital) | $1,000 to $5,000 | $600 to $2,269 |
| Hospital chargemaster | $1,000 to $18,000 | $600 to $3,500 |
| Freestanding imaging center | $400 to $1,000 | $300 to $900 |
If your bill shows a chargemaster figure for CPT 70553 or 72148 and you are uninsured or underinsured, you are almost certainly looking at a negotiable number.
Why Hospital MRI Bills Are So High
Several billing practices push MRI charges well above what the scan actually costs.
Facility fees. Hospital outpatient departments charge a separate facility fee on top of the professional fee for the radiologist. This fee goes toward overhead (the building, equipment, nurses) but can add hundreds or thousands to the bill. Freestanding imaging centers generally do not charge facility fees, which is why they are dramatically cheaper for the same scan.
Contrast administration upcoding. Some hospitals bill CPT 70553 (with and without contrast) when only one contrast phase was actually performed, or when no contrast was used at all. If your bill shows 70553 but your medical notes do not mention contrast injection, that is a potential billing error worth disputing.
Duplicate charges. Billing for both the technical component (the machine) and the professional component (the radiologist's read) is standard and expected. But some bills contain duplicate entries for one or both components, a straightforward error that adds hundreds to the total.
Unbundling. MRI sequences are sometimes billed as separate procedures when they should be combined under a single code. A lumbar spine scan that includes both sagittal and axial views should not generate two separate charges.
The CoveredUSA Bill Analyzer can compare each line item on your MRI bill against Medicare rates and flag procedures that are billed at 2x, 5x, or 10x the Medicare benchmark, giving you specific dollar amounts to dispute rather than a vague sense that something is wrong.
How to Check If You Were Overcharged
Step 1: Request Your Itemized Bill
Under federal law, you have the right to an itemized bill listing every charge by CPT code. Call the hospital billing department and ask specifically for the itemized statement with CPT codes included. Do not accept a summary bill.
Step 2: Match CPT Codes to What Actually Happened
Pull your medical records (or the radiology report) and confirm that the codes on your bill match what was actually performed. If you had a lumbar spine MRI without contrast, the bill should show 72148, not a contrast or multiple-contrast code.
Step 3: Compare Against Medicare Rates
The Medicare rate is public information. For CPT 70553, the national average is around $320 for non-facility settings. For CPT 72148, it is around $188 to $205. If your bill shows $2,500 for the same code, that is not necessarily fraud, but it is a number hospitals commonly negotiate down by 40% to 80% when patients push back.
Step 4: Use the CoveredUSA Bill Analyzer
Upload your itemized hospital bill to the free CoveredUSA Bill Analyzer. The tool reads each CPT code, compares it to the Medicare national rate, and generates a line-by-line breakdown of potential overcharges in under 30 seconds. It also checks for charity care eligibility based on your income.
Step 5: Dispute in Writing
Contact the hospital billing department in writing (email or certified mail). State the specific CPT codes, the Medicare benchmark rate, and the amount you consider reasonable. Ask them to explain in writing why their charge exceeds the benchmark by the stated multiple. Most hospitals will negotiate without requiring you to escalate further.
Step 6: Request Charity Care If Applicable
Nonprofit hospitals are required by federal law to offer charity care programs to low-income patients. If your household income falls below 200% to 400% of the federal poverty level, you may qualify for partial or full bill forgiveness regardless of whether you have insurance. Ask the billing department for their financial assistance application.

Does Insurance Cover MRI Costs?
Medicare
Medicare Part B covers MRI scans when a physician orders them as medically necessary. You pay your Part B deductible (which was $257 in 2025; confirm the 2026 figure at Medicare.gov) and then 20% of the Medicare-approved amount. For a brain MRI at $320, your 20% coinsurance would be about $64 after the deductible.
If you have Medicare and received an MRI bill far above the Medicare rate, the provider may have billed a non-participating rate, used a different facility type than expected, or made an error. An itemized review is worth the time.
Medicaid
Medicaid MRI coverage varies by state. Most states cover medically necessary imaging, but some require prior authorization. Reimbursement rates are typically lower than Medicare. If you are on Medicaid and received a large out-of-pocket bill for an MRI, contact your state Medicaid office. Billing patients above the Medicaid allowed amount is often prohibited.
Private Insurance
Insured patients typically pay a deductible and coinsurance. If you have not met your deductible, you may owe the full negotiated rate (not the chargemaster price). If you have met your deductible, you generally pay 20% to 30% of the negotiated rate. Always verify the negotiated rate (not the chargemaster rate) before accepting a bill.
No Insurance
If you have no insurance, you have the most room to negotiate. Hospitals are required to offer charity care if they are nonprofit. You can also ask for the cash-pay rate (often 30% to 50% below chargemaster) or negotiate a payment plan. Freestanding imaging centers are typically 50% to 80% cheaper than hospital outpatient departments for the same scan.
Hospital Price Transparency: What the Law Requires
As of 2021, CMS requires all U.S. hospitals to publish their chargemaster prices, discounted cash prices, and payer-specific negotiated rates in a machine-readable file. The 2026 OPPS/ASC final rule added requirements around how hospitals encode median allowed amounts.
In practice, compliance has been inconsistent. A 2024 HHS Office of Inspector General audit found that 37 of 100 randomly selected hospitals failed to meet at least one key transparency requirement. CMS had fined only 18 hospitals nationwide for non-compliance despite widespread violations.
The practical implication: even though the law requires price transparency, you may not find your hospital's negotiated rate for CPT 70553 or 72148 easily searchable. The tools you can rely on are Medicare's public Procedure Price Lookup tool and services like the CoveredUSA Bill Analyzer that parse these transparency files on your behalf.
Frequently Asked Questions
What is the average cost of an MRI in 2026?
MRI costs in 2026 range from $300 to $3,000 or more depending on body part, facility type, and whether contrast is used. At freestanding imaging centers, most scans run $300 to $900. At hospital outpatient departments, the same scan can cost $1,000 to $5,000 before any negotiation. Chargemaster prices on uninsured bills can exceed $10,000 for the same procedure.
What does CPT 70553 mean on my bill?
CPT 70553 is the billing code for an MRI of the brain with and without contrast. It means a radiologist performed a brain scan in two phases: one before contrast injection and one after. Medicare reimburses approximately $320 to $330 for this code at non-facility settings. If your bill shows a significantly higher amount, you may have room to negotiate.
What does CPT 72148 mean on my bill?
CPT 72148 is the billing code for an MRI of the lumbar (lower) spine without contrast. It is one of the most commonly ordered imaging procedures in the U.S. Medicare reimburses approximately $188 to $205 for this code. Hospital chargemaster prices for the same code can reach $2,000 to $3,500.
Can I negotiate an MRI bill?
Yes. Hospitals negotiate MRI bills regularly, and most billing departments expect it. Start by requesting an itemized bill with CPT codes. Compare the billed amount to the Medicare rate. Then call or write the billing department with a specific counteroffer. Hospitals commonly reduce bills by 30% to 60% when patients request it, especially for self-pay or underinsured patients.
What is a hospital chargemaster and why is it so high?
A chargemaster is a hospital's master list of prices for every service and procedure. Hospitals set chargemaster prices as a starting point for insurance negotiations. Insurers then negotiate large discounts off the list price. The chargemaster was never designed to be what patients actually pay, but uninsured patients often get billed at or near that rate unless they ask for the cash-pay discount or negotiate.
Is it cheaper to get an MRI at an imaging center vs. a hospital?
Almost always yes. Freestanding imaging centers do not charge hospital facility fees and typically bill at 30% to 70% below hospital outpatient rates. For a lumbar spine MRI (CPT 72148), you might pay $350 to $700 at a freestanding center versus $1,000 to $2,500 at a hospital outpatient department. If your physician's order does not specify a hospital, you can choose the lower-cost setting.
Does Medicare cover MRI scans?
Yes. Medicare Part B covers medically necessary MRI scans ordered by a physician. After your Part B deductible, you pay 20% of the Medicare-approved amount. For CPT 72148 at the $205 Medicare rate, that 20% coinsurance is about $41. If you are billed significantly more than that, review the bill for errors.
How do I find out what my hospital charged vs. what Medicare would pay?
Medicare's Procedure Price Lookup tool at Medicare.gov lets you search any CPT code by facility type and see the national average Medicare payment. For a full line-by-line comparison of your actual bill against Medicare rates, upload your itemized statement to the CoveredUSA Bill Analyzer, which does this comparison automatically and flags overcharges by dollar amount.
