CT scans are one of the most common diagnostic imaging procedures in the U.S. — and one of the most variable in price. The same abdomen CT can cost $350 at a freestanding imaging center and $5,800 at an academic medical center in the same metropolitan area. For patients with high-deductible insurance plans, that price gap comes directly out of pocket.
This article covers average CT scan costs by body part, why hospitals charge 5–15x more than freestanding imaging centers, how insurance and cash pricing play out in real scenarios, and the practical steps to find the cheapest CT scan near you without any sacrifice in diagnostic quality.
Average CT Scan Costs by Body Part
CT scan prices vary significantly by anatomy — abdominal and cardiac protocols require more imaging phases and processing time than a simple head or chest CT. The ranges below reflect national cash prices across hospital and outpatient imaging facilities, based on CMS price transparency data. They include both without-contrast and with-contrast protocols, which explains the wide ranges.
| Body Part | CPT Code(s) | Cash Price Range | With Insurance Range | Notes |
|---|---|---|---|---|
| Head / Brain | 70450, 70460 | $300 – $3,800 | $150 – $2,200 | Most common emergency CT; contrast adds $100–$300 |
| Chest | 71250, 71260 | $300 – $4,500 | $150 – $2,800 | Pulmonary embolism protocol (CTPA) is a specific variant |
| Abdomen | 74150, 74160 | $400 – $5,200 | $200 – $3,100 | Usually ordered with contrast for organ detail |
| Abdomen & Pelvis (combined) | 74177, 74178 | $500 – $6,500 | $250 – $4,000 | Most common combined protocol; contrast standard |
| Pelvis | 72192, 72193 | $350 – $4,200 | $175 – $2,600 | Often combined with abdomen; standalone less common |
| Cervical Spine (Neck) | 72125, 72126 | $350 – $3,800 | $175 – $2,300 | Trauma evaluation; bone detail superior to MRI |
| Thoracic Spine | 72128, 72129 | $350 – $3,800 | $175 – $2,300 | Compression fracture, disc evaluation |
| Lumbar Spine | 72131, 72132 | $350 – $4,000 | $175 – $2,400 | Bone and disc detail; MRI preferred for soft tissue |
| Cardiac (Coronary CTA) | 75574 | $600 – $5,500 | $300 – $3,500 | Specialized cardiac protocol; requires ECG gating |
| Sinus | 70486, 70487 | $300 – $3,200 | $150 – $1,900 | Common pre-surgery evaluation; often without contrast |
| Neck (Soft Tissue) | 70490, 70491 | $300 – $3,800 | $150 – $2,300 | Lymph nodes, thyroid, vascular evaluation |
| Extremity (Arm/Leg) | 73200, 73700 | $300 – $2,800 | $150 – $1,700 | Fracture detail, bone lesion evaluation |

Hospital vs Imaging Center: CT Scan Price Comparison
The same CT scan, interpreted by the same class of radiologist, can cost 5–15x more at a hospital than at a freestanding outpatient imaging center. The table below shows typical national mid-range estimates for six common CT types. Your area will vary — use them as a planning baseline, not a guarantee.
| CT Scan Type | Hospital (Avg Cash) | Imaging Center (Avg Cash) | Potential Savings |
|---|---|---|---|
| Head CT (without contrast) | $1,800 – $3,800 | $300 – $700 | ~65–80% |
| Chest CT (without contrast) | $2,000 – $4,500 | $300 – $750 | ~65–80% |
| Abdomen CT (with contrast) | $2,500 – $5,200 | $450 – $950 | ~65–80% |
| Abdomen & Pelvis CT (with contrast) | $3,000 – $6,500 | $500 – $1,100 | ~65–80% |
| Sinus CT (without contrast) | $1,500 – $3,200 | $300 – $600 | ~65–80% |
| Lumbar Spine CT | $1,800 – $4,000 | $350 – $750 | ~65–80% |
The price gap between facility types exists for the same structural reason as with MRIs: hospital radiology departments carry facility fee overhead from the entire hospital campus — 24/7 staffing, emergency infrastructure, administrative complexity — that freestanding imaging centers don't. The CT machine, imaging protocol, and radiologist interpretation are essentially equivalent; the building costs are not.
CT Scan With Contrast vs Without Contrast
Many CT orders specify contrast — and patients are often surprised to find their bill significantly higher than expected. Understanding when contrast is used and how much it adds helps you plan and ask the right questions before you show up for your scan.
What Is CT Contrast?
CT contrast is an iodine-based dye, usually injected intravenously (sometimes swallowed orally for GI imaging), that makes blood vessels, certain organs, and abnormal tissues appear brighter on the scan images. It substantially improves the radiologist's ability to detect tumors, abscesses, blood vessel problems, and active inflammation. Oral contrast (barium or water-soluble iodine) is used to outline the GI tract for abdominal imaging.
The Price Difference
CT contrast typically adds $100–$400 to the total cost, reflecting the dye cost plus additional scanner time for multi-phase protocols (scanning before contrast, at peak enhancement, and sometimes at a delayed phase). A dual-phase abdomen CT (with and without contrast) can add $200–$500 compared to a single without-contrast scan.
| Scan Protocol | Typical Cash Price Range | Common Use Cases |
|---|---|---|
| Head CT without contrast | $300 – $1,500 | Trauma, headache, hemorrhage screening |
| Head CT with contrast | $400 – $2,200 | Tumor evaluation, metastases, abscess |
| Chest CT without contrast | $300 – $1,800 | Lung nodule follow-up, low-dose lung cancer screening |
| Chest CT with contrast (CTPA) | $500 – $3,500 | Pulmonary embolism, aortic dissection |
| Abdomen CT without contrast | $400 – $2,200 | Kidney stones, bowel obstruction |
| Abdomen CT with contrast | $500 – $3,500 | Appendicitis, liver lesions, cancer staging |
| Abdomen & Pelvis CT with contrast | $500 – $4,500 | Most common combined protocol; abdominal pain workup |
| Sinus CT without contrast | $300 – $1,200 | Chronic sinusitis, pre-surgical planning (FESS) |
Do You Need Contrast?
Contrast is a clinical decision — not every CT requires it, and more contrast doesn't mean better imaging for every indication. Kidney stones are typically evaluated without contrast (the stones are highly visible without dye). Low-dose lung cancer screening CT is always without contrast. Before your scan, ask your ordering physician: "Is contrast medically necessary for the specific finding you're evaluating?" If the clinical question can be answered without contrast, the protocol can usually be modified. This is a simple question worth asking, especially if cost is a factor.
Patients with kidney disease, prior contrast reactions, or metformin use require special protocols before IV contrast CT. Always disclose these conditions to your ordering physician — contrast-related complications can be serious and are preventable with the right precautions.
Insurance Scenarios: When Does Coverage Actually Help?
Insurance doesn't automatically mean cheaper. Whether insurance helps — and by how much — depends entirely on your plan structure and where you are relative to your deductible.
Scenario 1: High-Deductible Plan, Deductible Not Met
On a $3,000 HDHP deductible that hasn't been reached, you pay the full contracted rate for any in-network CT scan. A hospital's contracted rate after the insurer's negotiated discount might be $1,200–$2,800 for an abdomen/pelvis CT — still far above the $500–$900 cash-pay price at a freestanding imaging center. In this scenario, cash at an imaging center almost always wins. You're paying out-of-pocket either way, but significantly less at a freestanding center.
Scenario 2: Low-Deductible Plan or Deductible Already Met
If your deductible is already met and you're paying only coinsurance (typically 20%), your in-network hospital cost on a $2,000 contracted rate is $400. That competes with or beats imaging center cash prices. Once past your deductible, insurance usually wins — but only if you're using an in-network facility. Out-of-network coinsurance can wipe out that advantage entirely.
Scenario 3: Prior Authorization Required
Most insurance plans require prior authorization for CT scans. Without it, your claim can be denied entirely — leaving you with the full bill. Prior auth is typically handled by your physician's office, but verify before you go: call your insurer's member line and confirm authorization was approved for your specific scan. A missing prior auth is the easiest way to turn a $300 co-pay into a $4,000 surprise bill.
The Imaging Center + Insurance Combination
The best outcome is often an in-network freestanding imaging center: you get the lower facility base price AND your insurance negotiated rate applies. Many national imaging chains (RadNet, Radiology Partners, Alliance HealthCare) are in-network with major insurers. Ask the imaging center: "Are you in-network with [my insurer] and what's my estimated cost after insurance?" That question, asked before booking, can save hundreds.

Find Cheap CT Scans Near MeHow to Find the Cheapest CT Scan Near You
CT scan prices are among the most negotiable and variable in outpatient medicine. These steps consistently produce the lowest prices for patients who know to take them:
1. Get the CPT Code Before You Call Anywhere
Your ordering physician's office will have the CPT code for your scan — it's on the order. Get it. "CT scan of my abdomen" is ambiguous and gets you vague answers. "CPT 74177" (CT abdomen and pelvis with contrast) is specific and gets you real prices. Every conversation with a facility scheduling desk goes faster and more accurately when you're quoting the exact code.
2. Start with Freestanding Imaging Centers, Not the Hospital
When your doctor refers you for a CT scan, they may default to their hospital's radiology department — because it's convenient, because the referral is automatic, or because they simply don't think about alternatives. You are not obligated to use that facility. Search for accredited freestanding imaging centers in your area. Look for ACR (American College of Radiology) accreditation as a quality indicator — it's the same standard as hospital departments. Use the CarePrices compare tool to see what specific facilities charge for your CPT code.
3. Ask Explicitly for the Cash-Pay / Self-Pay Price
Many imaging facilities have a cash-pay price that's 20–50% below their standard rate — but it won't be offered unless you ask. Call and say: "What is your cash-pay price for CPT [code]?" Most billing staff will give you a number. If they say "it depends on insurance," clarify: "I'm asking what the self-pay price is if I pay cash on the day of service." That question usually produces a real answer.
4. Ask About Cash Pay vs Using Your Insurance
At freestanding imaging centers, there's often a meaningful difference between what they'd charge your insurer and their cash rate. Ask both questions: "What's my cost if I use my insurance?" and "What's your cash-pay price?" Compare the two numbers. Sometimes the cash price is lower than your in-network copay or coinsurance amount — especially if you're still in your deductible.
5. Look for Imaging Chain Cash-Pay Programs
Several large radiology chains operate formal cash-pay programs with published flat rates for common scans. RadNet, Shields MRI, and Alliance HealthCare have marketed cash programs in certain markets. These aren't available everywhere, but they're worth searching for in your area. A CT scan for $250–$400 through a chain cash program is common in competitive markets.
6. Hospital Financial Assistance Programs
If you need imaging at a hospital for clinical reasons (emergency, specialist preference, no imaging center nearby), ask about the hospital's financial assistance or charity care program before paying. Most nonprofit hospitals are required to offer charity care and must screen patients for eligibility. For patients below 200–400% of the federal poverty level, cost can be dramatically reduced. The hospital's financial counselor can walk you through the application — it's typically quick and doesn't require a formal application if you qualify at the self-declaration level.
CT Scan vs MRI: Which Should You Get, and Which Costs Less?
CT scans and MRI are both cross-sectional imaging modalities, but they work completely differently and excel at different clinical questions. The choice between them is always a clinical decision — but understanding the differences helps you have a more informed conversation with your physician.
| Factor | CT Scan | MRI |
|---|---|---|
| Technology | X-ray (ionizing radiation) | Magnetic field + radio waves (no radiation) |
| Scan time | Seconds to a few minutes | 20–60 minutes |
| Average cash price (outpatient) | $300 – $900 | $500 – $1,600 |
| Best for | Bone fractures, internal bleeding, lung disease, trauma, kidney stones, stroke (early) | Soft tissue detail, brain/spinal cord, joints, tendons, ligaments, tumors |
| Claustrophobia | Rarely a problem (open bore, fast scan) | Significant issue; open MRI available but lower quality |
| Radiation exposure | Yes — dose varies by body part; chest CT ≈ 2 years natural background | None |
| Contrast type | Iodine-based (IV or oral) | Gadolinium-based (IV only) |
CT is faster, cheaper, and better for bony structures and emergency evaluation. MRI is more expensive, takes longer, but produces superior soft-tissue contrast without radiation. For joint injuries, neurological evaluation, and cancer staging in soft tissue, physicians typically prefer MRI when time permits. For trauma, suspected stroke, chest pain workup, and abdominal emergencies, CT is often first-line. Many cancer staging and follow-up protocols use both modalities.
If your physician orders a CT when you were expecting an MRI (or vice versa), ask why. Understanding the clinical rationale helps you make an informed decision — and occasionally, there's flexibility in the choice based on your specific presentation. See our companion article on MRI costs by body part for a parallel breakdown of MRI pricing.
If cost is a genuine concern, discuss it with your physician before the scan is ordered. There is often flexibility in modality, protocol, and facility — but once you're in the radiology department waiting room, that conversation is much harder to have.
Low-Dose CT for Lung Cancer Screening: A Special Case
Low-dose CT (LDCT) for lung cancer screening is a specific protocol for high-risk patients — typically adults aged 50–80 with a 20+ pack-year smoking history who currently smoke or quit within the past 15 years. It uses a fraction of the radiation of a standard chest CT and is specifically designed for screening rather than diagnostic imaging.
LDCT for lung cancer screening is covered at zero cost-sharing (no copay, deductible, or coinsurance) by most insurance plans under the Affordable Care Act's preventive services mandate — as long as you meet the eligibility criteria and it's billed as preventive screening, not diagnostic imaging. This means eligible patients should pay nothing out of pocket at an in-network facility.
The cash price for LDCT lung cancer screening at freestanding imaging centers is typically $100–$300, making it one of the most affordable imaging studies when cash pay is necessary. If you meet the eligibility criteria, confirm the billing code (CPT 71271) with your ordering physician and insurer before scheduling to ensure zero cost-sharing applies.
The Data Behind This Article
The price ranges in this article are derived from CMS hospital price transparency data (45 CFR § 180), which requires hospitals to disclose gross charges, discounted cash prices, payer-specific negotiated rates, and de-identified minimum and maximum negotiated rates for all items and services. Freestanding imaging center prices reflect published cash rates, direct facility inquiries, and CMS outpatient prospective payment data.

The Bottom Line
A CT scan is one of medicine's most powerful diagnostic tools — and one of its most aggressively variable in price. The scan quality at an accredited freestanding imaging center is clinically equivalent to a hospital radiology department for the vast majority of outpatient studies. The price is not.
The most reliable path to a lower CT scan price: get the CPT code upfront, call two or three freestanding imaging centers and ask for their cash-pay price, compare that against your insurance estimate, and book the lower of the two. For high-deductible patients who haven't met their deductible, cash at a freestanding center almost always wins. For patients who've met their deductible, insurance at an in-network imaging center is usually cheapest.
The five-minute phone call to ask for a self-pay price before booking is the single highest-ROI action available in outpatient healthcare. For a $3,000–$6,000 exam, it's worth making.
