Before you book: three questions that change the price

  1. Is this the self-pay price, and does it include the doctor, anesthesia and any lab or pathology? Those are often billed separately.
  2. Can you give me the price in writing, with the billing codes it covers?
  3. What happens to the price if something extra is needed during the procedure?

Quick take

  • John H. Stroger, Jr. Hospital is the lowest-cost option at $313 - $821 below the median posted price ($1,134), just by choosing where you go.
  • Ask for the cash price if your deductible isn't met - the median cash price here is $1,134, and it's often lower than what insurance pays before your deductible is satisfied.
  • Independent imaging centers often charge much less than hospital outpatient departments for the same scan and may not appear in this hospital-only dataset - ask your doctor whether one is an option.

How where you go changes what you pay for ct abdomen

The same ct abdomen bundles different services depending on the setting - facility fee, surgeon fee, and anesthesia each arrive as separate bills. Estimated ranges below reflect the typical full bundled cost, including all expected charges.

Hospital Outpatient
$204–$5,255
  • Facility fee $204–$5,255

Estimated from CMS fee schedules + commercial rate multipliers

Hospital Inpatient
$219–$5,255
  • Facility fee $219–$5,255

Estimated from CMS fee schedules + commercial rate multipliers

Independent Imaging Center
$441–$1,000
  • technical_component $301–$628
  • professional_interpretation $140–$372

Estimated from CMS fee schedules + commercial rate multipliers

Illinois presents two distinct markets: Chicago (highly competitive, high commercial rates, major academic medical centers) and downstate (lower density, smaller regional systems, lower rates). Northwestern Medicine, Advocate Aurora Health, and Rush University Medical Center compete aggressively in the Chicago market. Downstate Illinois prices typically run 20–35% below Chicago-area rates for identical services. Abdominal CT pricing follows the same site-of-service pattern as other imaging: the identical scan costs 3–6× more at a hospital outpatient department than at an independent imaging center. With contrast vs. without contrast are different CPT codes and different prices, so confirm which your doctor ordered before scheduling. If ordered non-urgently, calling ahead to compare cash prices across independent imaging centers near you is the single most effective cost reduction strategy.

Why prices vary - and what it means for your coverage

Setting matters too: the median outpatient price is $1,153 versus $1,997 inpatient (about 1.7× more), so where a procedure happens often matters more than which hospital you pick. Whether the scan happens in a hospital outpatient department (which adds a separate facility fee) or a freestanding imaging center is usually the single biggest driver of price for this procedure.

None of the prices above are what you'll necessarily owe: your deductible, out-of-pocket maximum, and each provider's network status all still apply.

Your situation Estimated out-of-pocket
Deductible not yet met ~$1,287
Deductible met - 20% coinsurance ~$257
Out-of-network provider $2,831+

Frequently asked questions: CT Abdomen costs in Illinois

How much does a CT Abdomen cost in Illinois?

The typical insurer-negotiated rate is $112, with most facilities between $104 and $228 (based on 140 hospitals reporting negotiated rates). That is the hospital's negotiated rate alone; with physician fees, a commercially insured patient's full episode is typically $459–$2,338. Posted cash prices at the middle 80% of Illinois hospitals run $250–$2,862; outlier facilities above and below that range are left out. What you pay depends on the facility, your insurance, and whether you have met your deductible.

Where is the cheapest place to get a CT Abdomen in Illinois?

Based on declared prices, the lowest posted price in our Illinois data is John H. Stroger, Jr. Hospital in Chicago at about $313. By metro, Rockford has the lowest median ($255). Independent imaging centers are often cheaper still and may not appear in hospital price data - ask your doctor whether one is an option.

Why is a CT Abdomen so much cheaper at some Illinois hospitals?

Typical prices vary about 2.2× (25th to 70th percentile of negotiated rates) because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Illinois, the median cash (self-pay) price is $1,134 versus a median negotiated rate of $862 - about 1.3× higher. Asking for the cash price as well as your insurer's negotiated rate is often the single biggest lever on what you pay.

How much will I actually pay out of pocket for a CT Abdomen in Illinois?

Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.

What matters before you schedule

Imaging center vs. hospital

Hospital outpatient departments typically charge 2-4x more than independent imaging centers for the same ct abdomen - same outcome, very different bill. The ER charges the most of any setting and should only be used when the situation is medically urgent. Call ahead and ask for a self-pay or cash quote at each setting you're considering.

With vs. without contrast

Which type your doctor orders for this ct abdomen changes the billing code, and what you pay. For example: A standard ct abdomen with no contrast dye - the most common and lowest-cost version.

This is shoppable

CT Abdomen is elective and schedulable, so you have time to compare facilities before booking - hospital outpatient prices often run 2-4x higher than alternative settings for the identical clinical outcome.

What to ask before you book

Get the CPT code from your doctor, confirm every provider involved (not just the facility) is in-network, ask for the cash-pay rate if you're uninsured or haven't met your deductible, and request a written estimate for ct abdomen before you schedule.
