A chest CT scan costs around $711 on average, but the price you actually pay can range from about $400 to over $2,700 depending on where you live, where you get the scan, and whether you have insurance. That’s a wide spread, and understanding what drives the price can save you hundreds of dollars.
Average Cost Across the U.S.
The national average for a chest CT scan sits around $711, but that number masks enormous variation. In lower-cost markets like Tampa, Florida, prices range from $400 to $1,050. In higher-cost cities like Baltimore, Maryland, the same scan runs $1,100 to $2,775. The facility you choose within the same city can matter just as much as the city itself.
These figures represent the total billed price before insurance. If you have coverage, your out-of-pocket share will typically be much less, though the exact amount depends on your plan’s deductible, copay structure, and whether the facility is in-network.
What Makes the Price Go Up or Down
Several factors can shift your final bill significantly.
Contrast dye. A chest CT with contrast will cost more than one without. The type of dye matters too: iodine-based contrast tends to be more expensive than barium-based contrast. On top of the dye itself, you may need a blood test beforehand to confirm your kidneys can safely process the dye, and if you’re at higher risk for a reaction, you’ll need extra monitoring during the scan. Each of these adds to the total.
Facility type. Hospital-based imaging centers generally charge more than freestanding radiology centers. University hospitals and research institutions often have higher rates as well. Dedicated imaging centers that perform a high volume of scans tend to offer the most competitive pricing.
Geographic location. Imaging costs vary substantially by state. A pricing study found that states like California, Nevada, New Mexico, and Alabama tend to be among the least affordable for diagnostic imaging, while Rhode Island, Arkansas, New Hampshire, and Oklahoma rank among the most affordable. Even within a single metro area, prices at different facilities can differ by hundreds of dollars.
What Insurance Typically Covers
Most private insurance plans cover chest CT scans when a doctor orders them to diagnose or monitor a medical condition. You’ll pay your standard cost-sharing: a copay, coinsurance percentage, or charges applied toward your deductible. The key variable is whether the imaging center is in your plan’s network. An out-of-network scan can cost you two to three times more out of pocket.
If you have Medicare Part B, you pay 20% of the Medicare-approved amount for diagnostic imaging after meeting your annual deductible. One important detail: if you get the scan at a hospital outpatient department rather than an independent facility, you’ll also owe a hospital copayment that can exceed 20%. Medicare also requires that any freestanding imaging center be accredited before it will pay for your scan, so it’s worth confirming accreditation before your appointment.
Lung Cancer Screening: A Special Case
If you’re getting a low-dose chest CT specifically for lung cancer screening, the cost rules change. Medicare covers this scan at zero cost to you if you meet all of the following criteria: you’re between 50 and 77, you have no symptoms of lung cancer, you’re a current smoker or quit within the last 15 years, you have a smoking history of at least 20 pack-years (roughly one pack a day for 20 years), and your doctor orders the test.
Under the Affordable Care Act, most private insurers are also required to cover preventive lung cancer screening without charging you a copay or coinsurance if you meet similar eligibility criteria. This only applies to the screening version of the scan. If your doctor orders a chest CT because you have symptoms like a persistent cough or chest pain, it’s classified as diagnostic rather than preventive, and normal cost-sharing applies.
How to Lower Your Out-of-Pocket Cost
If you’re paying out of pocket or facing a high deductible, a few strategies can cut your costs significantly.
- Call multiple facilities for quotes. Prices for the same scan in the same city can vary by $500 or more. Freestanding imaging centers that specialize in scans almost always charge less than hospital-based radiology departments.
- Ask about cash-pay discounts. Many facilities offer reduced rates if you pay upfront without running the charge through insurance. This can sometimes beat your insured price if you haven’t met your deductible.
- Request a good faith estimate. Under federal law, any healthcare provider must give you a written cost estimate before your scan if you’re uninsured or choosing not to use insurance. This protects you from surprise charges.
- Ask about payment plans. If the upfront cost is a barrier, many imaging centers offer interest-free payment plans that let you spread the bill over several months.
The single most effective thing you can do is compare prices before booking. Get the specific CPT code from your doctor’s order (for a standard chest CT without contrast, it’s typically 71250; with contrast, 71260) and call three or four facilities in your area. The price differences are often dramatic enough to justify a slightly longer drive.
