Outpatient facility charge only. These are the hospital’s own published prices for the facility part of the visit. The doctor’s or radiologist’s fee is billed separately and isn’t included, and your final bill can differ (extra tests, contrast, supplies). Not medical or insurance advice.

How to get the cash price
- Pick a hospital from the city table and call its price-estimate or scheduling line.
- Say you are a self-pay patient and quote CPT 45378; ask what the price becomes if a biopsy or polyp removal is needed.
- Ask for a Good Faith Estimate in writing. If the bill comes in $400 or more above it, you can dispute it. See Good Faith Estimates.
