Points to raise when you call for a quote.
- Quote the billing code, such as 74176 for CT Abdomen and Pelvis without Contrast, and ask for the cash or self-pay price.
- Ask for an itemized estimate and what it includes and leaves out, since the listed rows are facility charges.
- Ask whether separate professional bills may follow, such as a radiologist reading an MRI, CT or ultrasound, an ER physician for an ER visit, or a physician and anesthesia for a colonoscopy.
What is missing and when the file was updated. No rows carry a data note, and no values were published as $0 or blank or left out as likely file errors. The file is a CSV with 106,643 items, updated 2026-04-01 and accessed by us 2026-10-08, so current prices may have changed since then.
General information about using published prices, not medical, legal or financial advice. Confirm your own cost with the hospital and your insurer. Our methodology
Understanding the Columns
Gross Charge: The chargemaster price before any discounts. Rarely what patients pay. It is primarily a starting point for insurance negotiations.
Cash/Self-Pay: The discounted rate hospitals offer to uninsured patients. Ask about financial assistance programs for further reductions.
Insured Range: Lowest to highest negotiated rates across all payers. Medicare rates are typically lowest; commercial plan rates highest.
About Facility Fees
Prices shown are facility fees only. You'll also receive separate bills from the physician performing the procedure.
Imaging procedures include a facility fee plus a radiologist's reading fee. Surgical procedures add surgeon, anesthesia, and pathology fees.
For a more complete estimate, contact the hospital's financial counselling office or your insurer to request a pre-service cost estimate that includes all expected professional fees.
