How Much Does a CT Scan Cost? (2026 Price Guide)

The average CT scan costs $3,275 at hospital outpatient departments, according to the Health Care Cost Institute—but the same scan runs $270 to $600 at a freestanding imaging center. Hospital ER CT scans can reach $7,000 or more when facility and emergency fees are stacked on top of the scan itself. This guide explains exactly what drives CT costs, what every line on your bill means, and how to dispute charges that are too high.

1. CT scan costs by type and CPT code

A CT scan (computed tomography) uses a series of X-ray images taken from different angles to create detailed cross-sectional pictures of your body. CT scans take 5 to 15 minutes and are better than MRIs for viewing bones, detecting bleeding, and assessing organ injuries. Each type of scan has a specific CPT code on your bill.

BillKarma data shows CT scan charges in hospital ERs average 7.2x the Medicare-allowed amount—higher than almost any other imaging service. Even at hospital outpatient departments (not ERs), CT charges average 5.4x the Medicare rate. At freestanding imaging centers, the average drops to 2.3x.

2. Same CT scan at 4 different facility types

The facility where you get your CT scan matters more than almost any other factor. Here’s what a CT abdomen/pelvis with contrast (CPT 74177) costs at four different facility types:

The same scan—same CPT code, same contrast protocol, same radiologist report—can cost $350 or $7,500 depending entirely on where you walk in. The imaging center saves money because it does not carry the overhead of a 24/7 emergency department, surgical suites, or inpatient beds.

3. What’s on a CT scan bill

CT scan bills from hospital outpatient departments commonly include three to five separate charges. Here’s an annotated example of a hospital CT bill with common problem charges flagged:

Charge-by-charge breakdown:

• Technical component ($3,390) — The hospital facility fee for the CT scanner, technologist, and overhead. At 12.7x the Medicare rate, this is the primary target for a dispute.
• Professional component ($280) — The radiologist’s interpretation fee. Often billed by a separate radiology group. At about 1x Medicare, this is reasonable.
• Contrast material ($420) — Hospitals must document the volume of contrast used. 120 mL is on the high end for an abdomen/pelvis CT (typical is 80–100 mL). Request nursing notes to verify the quantity actually administered.
• ER visit Level 5 ($895) — Level 5 is the highest ER evaluation code and should only be applied to the most complex emergency visits. If you were seen as an outpatient (not an ER patient), this code does not belong on this bill. See our guide on ER billing errors for how to dispute E&M upcoding.

4. Contrast dye charges explained

Contrast dye (also called contrast medium or contrast agent) is injected intravenously before or during a CT scan to highlight blood vessels, organs, and tumors more clearly. Iodine-based contrast is used for CT scans. The dye itself costs hospitals about $8 to $25 per 50 mL dose at wholesale prices.

Despite the low wholesale cost, hospitals bill $150 to $600 for contrast administration. This charge bundles the dye, the IV supplies, the nurse’s time to administer it, and a monitoring period afterward (since contrast can cause allergic reactions in rare cases).

What to watch for on your bill:

• Duplicate contrast charges — If you had one CT scan, you should see one contrast charge. Two contrast charges on a single-scan bill is likely a billing error.
• Contrast billed separately AND bundled into the CPT code — Some hospitals bill contrast as a separate line item even though the CPT code for “with contrast” already accounts for it. This double-billing is a known issue worth flagging.
• Contrast volume documentation — You can request nursing notes to verify the volume of contrast administered matches what was billed.

5. The radiology read fee

Every CT scan includes two separate services: (1) performing the scan (technical component) and (2) a radiologist interpreting the images and writing a report (professional component). These are often billed separately—sometimes by two different companies.

You may receive two separate bills: one from the hospital for the technical component (the scan itself) and a second bill from a radiology group for the professional component (the read). This is normal. However, it means you need to check both bills for errors.

The professional read fee typically runs $100 to $400 and is more closely tied to Medicare rates than the technical fee. The technical component is where hospitals exercise the widest pricing latitude and where the largest markups occur. Use our cost calculator to benchmark both components separately.

6. How ER CT scans get marked up

Getting a CT scan in the emergency room is dramatically more expensive than the same scan in an outpatient setting. Here’s why ER CT bills are so high:

1. ER facility fee — Every ER visit includes a facility fee just for walking through the door, regardless of what tests are run. These fees range from $400 (Level 1, minor) to $1,200+ (Level 5, severe).
2. E&M (evaluation and management) charge — On top of the facility fee, you’re charged for the physician’s evaluation. Hospitals often upcode these to Level 4 or Level 5 even for straightforward visits. A Level 5 E&M code (99285) adds $600–$1,000 to the bill.
3. After-hours surcharges — CT scans done at night or on weekends may include add-on codes for after-hours technologist fees.
4. Higher technical fee baseline — ER CT technical fees are set higher than outpatient CT fees even before the E&M and facility charges are added.

If you received a CT scan in the ER and the visit was not a true emergency, our ER billing guide explains how to dispute the E&M level and facility fee. For future non-emergency imaging needs, an urgent care center or freestanding imaging center will cost a fraction of ER prices.

7. How to get a CT scan cheaper

If your condition is not an emergency and your doctor orders a CT scan, you have options to significantly reduce the cost:

• Request a referral to a freestanding imaging center. Ask your doctor to send the referral to an independent radiology center rather than the hospital. Prices are typically 60–80% lower. The scan quality and the radiologist’s report are equivalent for routine outpatient CT scans.
• Ask for the cash price. Many freestanding imaging centers offer cash prices of $270 to $600 for CT scans. If you’re pre-deductible, paying cash can be cheaper than going through insurance at a hospital.
• Use hospital price transparency data. Since 2021, hospitals must publish their prices. Use our pricing directory to compare CT scan prices at every hospital in your area before you schedule.
• Check if prior authorization is required. If your insurer requires PA and your doctor doesn’t get it, your claim may be denied. Confirm PA status before your scan date.
• Time your scan strategically. If you’re close to meeting your deductible later in the year, scheduling at a hospital (while expensive) may make sense because costs count toward your max. Early in the year, an imaging center cash price may be cheaper than your deductible exposure.

8. Disputing inflated CT charges

CT scans are one of the most commonly overbilled imaging services. Here’s how to challenge a CT bill that looks too high:

1. Get the itemized bill. Call the hospital and ask for a fully itemized bill with CPT codes for every charge. Do not accept a summary statement.
2. Compare to Medicare rates. Use our calculator to look up the 2026 Medicare rate for each CPT code. Document the markup multiple for each line item.
3. Identify specific errors: duplicate charges, wrong CPT code (e.g., billed “with contrast” when no contrast was used), upcoded ER visit level, or contrast quantities that don’t match clinical records.
4. Call the billing department. Reference the Medicare rate: “Medicare pays $267 for CPT 74177. I am being charged $3,390—12.7x the Medicare rate. I am requesting a reduction to the 50th percentile of commercial rates for this service.”
5. Escalate to patient advocate or financial assistance. If the billing department won’t negotiate, ask to speak with the hospital’s patient financial advocate. Nonprofit hospitals must offer charity care and financial assistance programs. Our guide on getting medical bills reduced has the full script.
