MRI Cost in Chattanooga, TN

A magnetic resonance imaging (MRI) scan uses a strong magnetic field and radio waves to produce detailed cross-sectional images of structures inside the body. The patient lies on a table that slides into a large tube-shaped scanner while the machine captures images, and the scan typically involves holding still while the equipment makes repetitive knocking sounds. A non-contrast study does not use injected contrast dye. The facility fee covers the hospital's scanner, technologist, room, and support staff. This page covers two billing codes: HCPCS 72148 (MRI lumbar spine without contrast) and HCPCS 70551 (MRI brain without contrast). All prices come from CMS-mandated hospital price transparency files.

What These Prices Mean

Understanding the price columns
The gross charge is the hospital's full list price, also called the chargemaster price. The cash price is what a self-pay patient is asked to pay. The insured range shows the lowest and highest negotiated rates across insurance plans. At Erlanger Baroness, the lumbar spine MRI has a $297 gross charge and a $156.82 cash price, or 53% of gross. At CHI Memorial Hixson, the same code has a $2,404 gross charge and a $711.59 cash price, only 30% of gross. The larger percentage discount still produces a higher cash price because the starting gross charge is much higher. At both Parkridge hospitals, cash equals gross at $10,890.27, a 100% ratio with no discount. Patients on high-deductible plans who have not met their deductible owe the negotiated rate, not the gross charge.

Code differences
Code 72148 images the lumbar spine, while code 70551 images the brain. Both are without contrast. At Erlanger Baroness, the brain scan cash price is $165.79, which is $8.97 above the lumbar spine price of $156.82. At CHI Memorial Hixson, the difference is $106.85 ($818.44 versus $711.59). At CHI Memorial Chattanooga, it is $152.70 ($1,169.60 versus $1,016.90). Parkridge shows identical $10,890.27 prices for both codes.

Why MRI Prices Vary

Hospital pricing structures
Gross charges for these scans range from $297 at Erlanger Baroness to $10,890.27 at both Parkridge hospitals, a gap of $10,593.27 for the lumbar spine code. The gap in cash prices is also wide: $156.82 to $10,890.27, a difference of $10,733.45. The CHI Memorial hospitals fall in between, with gross charges of $2,404 (lumbar) and $2,765 (brain). Cash discounts differ by facility: about 53% of gross at Erlanger Baroness, 30% at CHI Memorial Hixson, 42% at CHI Memorial Chattanooga, and 100% at the Parkridge hospitals. Each hospital sets its own chargemaster and discount policy, so the same scan carries very different self-pay prices.

Facility type and alternatives
All five facilities in this dataset are hospitals, and hospital outpatient departments bill facility fees that reflect overhead such as emergency readiness, staffing, and equipment. Freestanding imaging centers are not in this dataset and may price the same scans differently. Within the hospitals listed, cash prices for these two codes span $156.82 to $10,890.27.

Paying cash? Health insurance could lower your MRI cost.

Published cash prices on this page range from $711.59 to $10,890.27 (including hospitals that publish cash equal to gross charge, marked with * in the table). The lowest insured rate in the price table is $170.96 (Parkridge East Hospital). Insured rates depend on the plan, and the lowest are often Medicaid, CHIP or Medicare Advantage plans, so they may not reflect what a commercial or marketplace plan pays. If you are uninsured, a marketplace health plan could reduce your out-of-pocket cost for this procedure.

What to Do With These MRI Prices

Name the scan and the contrast before you call. This page covers two codes: 70551 (brain, without contrast) and 72148 (lumbar spine, without contrast). Ask the ordering office for the exact CPT code and whether the order is with or without contrast, since contrast changes the code. Then ask each hospital for its cash price and an itemized estimate under that code.

Put your quote next to these figures. Cash prices here vary a lot by hospital. CHI Memorial Hospital Hixson lists $711.59 for 72148, while Parkridge East Hospital and Parkridge Medical Center list cash equal to the gross charge of $10,890.27 for both codes. For the Parkridge rows, cash sits above every insured rate at that hospital, so a quote near $10,890.27 is the published gross charge, not a negotiated figure. If you have insurance, you can ask your plan which rate applies. Insured rates on this page run from $186.96 up to $9,583.44.

Expect the scan to bring more than one bill. The prices here are the hospital's technical (facility) charge only. The radiologist who reads your images bills separately, and you can ask whether that group is in your network. Check the itemized bill for a facility line, a professional reading line, and any contrast or supply charges.

Remember what this page does not show. Outpatient and freestanding imaging centers are not in this dataset and may price differently. Every row on this page has a published cash price and gross charge, so there are no $0 or blank gaps to misread here.

Financial assistance and discounts. Nonprofit hospitals are required to publish a financial assistance policy, and the billing office can send it with an application. Some hospitals also offer prompt-pay or self-pay discounts; these vary by hospital and are not included in this data. If you are uninsured or not using insurance for scheduled care, you can ask the provider for a good faith estimate before the appointment.

What Patients Ask About MRI Costs

How much does a mri cost without insurance in Chattanooga?

Cash prices for MRI without insurance in Chattanooga range from $156.82 to $10,890.27. For the lumbar spine (72148), cash prices are $156.82 at Erlanger Baroness, $711.59 at CHI Memorial Hixson, $1,016.90 at CHI Memorial Chattanooga, and $10,890.27 at both Parkridge East and Parkridge Medical Center. For the brain (70551), they are $165.79, $818.44, $1,169.60, and $10,890.27 at the same facilities. The brain code runs higher than the lumbar code at the Erlanger and CHI Memorial hospitals. These are facility fees only. Physician and professional fees are billed separately.

Why is the gross charge so much higher than the cash price?

The gross charge is the hospital's chargemaster price, a full list price that almost no one pays. Insurers negotiate lower rates, and self-pay patients are typically offered a cash price. Cash is 53% of gross at Erlanger Baroness ($156.82 of $297), 30% at CHI Memorial Hixson ($711.59 of $2,404), and 42% at CHI Memorial Chattanooga ($1,016.90 of $2,404). CHI Memorial Hixson's 70% discount is larger than Erlanger Baroness's 47%, yet its cash price is still higher because its starting gross charge is much larger. Parkridge lists cash equal to gross at $10,890.27, so no discount applies.

Does insurance cover a mri?

Coverage depends on your plan and whether the scan meets the plan's medical necessity criteria. Many plans require prior authorization for non-emergency MRI. Negotiated rates vary widely: for the brain MRI, payer rates range from $57.05 to $9,583.44 across 755 listed rates. If you are on a high-deductible plan and have not met your deductible, you owe the negotiated rate for your plan, not the gross charge. Your out-of-pocket cost depends on your deductible, copay, and coinsurance, so the plan's rate for your specific insurer is the figure that applies.

Are there additional fees beyond the mri facility charge?

Yes. The prices on this page are hospital facility fees, which cover the scanner, room, technologist, and equipment. A radiologist's fee for reading and interpreting the images is a professional fee billed separately, often by a different practice than the hospital. These amounts are not included in the hospital price data. If an MRI is performed in the emergency department, a separate ER facility fee is also billed. Billing for the ordering physician's visit is separate as well. Dollar amounts for these additional fees are not part of the hospital transparency files used here.

What is the cash price for an MRI brain scan at CHI Memorial Hospital Hixson?

CHI Memorial Hospital Hixson lists a cash price of $818.44 for MRI Brain Without Contrast (CPT 70551), which is 30% of its gross charge of $2,765. This is a facility charge only, so separate bills such as a radiologist's reading may not be included in this figure.

What is the highest published MRI price in Chattanooga, TN?

The highest published cash price on this page is $10,890.27 for MRI Brain Without Contrast (70551) at Parkridge East Hospital. Parkridge East Hospital and Parkridge Medical Center both list this amount for both codes, and it matches their gross charge. These are facility charges only.

What is the lowest cash price for an MRI in Chattanooga?

The lowest published cash price on this page is $711.59 for MRI Lumbar Spine Without Contrast (72148) at CHI Memorial Hospital Hixson. That is a facility charge only. All 8 hospital and code rows on this page have a published cash price, so none are missing.

Do Parkridge East Hospital and Parkridge Medical Center offer a self-pay discount on MRI?

No self-pay discount is published for either hospital. Both Parkridge East Hospital and Parkridge Medical Center list a cash price of $10,890.27 for both codes, equal to the gross charge (100%). This is the facility charge only, and it is the published figure, not a confirmed quote.

How much do insurance rates for an MRI lumbar spine vary at Parkridge Medical Center in Chattanooga?

Parkridge Medical Center publishes 119 rates for MRI Lumbar Spine Without Contrast (72148). They run from $171.73 for Aetna to $9,583.44 for Beech Street and Prime Health, about 56x the lowest. Health One Alliance is listed at $221.23. These are facility charges only, and the rate depends on the insurer and plan.
