What is actually in the file
Each hospital publishes a file covering the items and services it provides, with several prices attached to the same service:
| Column you will meet | What it means |
|---|---|
| Gross charge | The chargemaster list price. The highest number, paid by almost nobody. |
| Discounted cash price | What the hospital charges a self-pay patient who asks. Frequently far below gross. |
| Payer-specific negotiated rate | What a named insurer actually pays. This is the market price. |
| De-identified min and max | The range across all payers, useful when your own plan is not listed clearly. |
The gap between the first row and the third is the entire reason this rule exists. Seeing a gross charge of one number next to a negotiated rate a fraction of that size changes what you are willing to accept on a bill.
Where to find it
Start on the hospital’s own website and look for wording like price transparency, standard charges, or machine-readable file — typically in the footer or under patient billing. The file itself is usually CSV or JSON with a name containing the hospital’s tax identification number.
Alongside it, most hospitals publish a consumer price estimator for common services. That tool is easier and worth trying first; the raw file is the fallback when the estimator does not cover your service or you want the negotiated rate for your specific plan.
How to use it without a data background
1. Get the code, not the name. Ask the ordering physician’s office for the CPT code for the procedure. Searching for “MRI” in a price file returns dozens of rows; searching a code returns yours.
2. Open it in a spreadsheet and filter. Column names vary between hospitals, which is the main friction. Find the column with codes, filter to yours, then read across the row.
3. Read three numbers: the cash price, your insurer’s negotiated rate if it appears, and the de-identified maximum. Your realistic exposure sits between the cash price and the negotiated rate, not at the gross charge.
4. Then call anyway. The file tells you what the hospital charges for the service. It does not tell you whether your case needs contrast, an extra view, a pathology read, or a facility fee at that particular site. Use the number to ask a sharper question: “The published cash price for this code is X. Is that what I would be billed, and what else would be billed separately?”
What the files do not solve
They are often stale or incomplete. Compliance varies. If a file is missing or unreadable, that is worth noting — but it does not change your rights on the bill afterward.
They do not include physician fees. The hospital’s file covers the hospital. The surgeon, the anesthesiologist and the radiologist bill separately and are not in it.
They are not a quote. A number in a public file is not a promise about your specific case. The written good faith estimate is the closest thing to that, and uninsured or self-pay patients are entitled to one before scheduled care.
After the fact, the file still helps
If a bill has already arrived and looks unreasonable, the price file gives you a factual basis for the conversation instead of an argument about fairness: “Your published cash price for this code is X, and I was billed Y. Please explain the difference, and send an itemized bill.”
That, combined with New York’s ceiling on what an uninsured patient can be charged, is a stronger position than most people realize they have. How the ceiling works.
Questions people ask
Are these files really free?
Yes. Publication is required and access cannot be gated behind a login or a fee.
What if the hospital’s file is impossible to open?
Try the consumer estimator instead, then call patient financial services and ask for the cash price for the specific code in writing. Note the date and who you spoke to.
Does the negotiated rate tell me what I will pay?
No. It tells you what your insurer pays. Your share depends on your deductible, copay and coinsurance — but the negotiated rate is the base those percentages apply to, which is why it matters.
Do these rules cover imaging centers and surgery centers?
The federal hospital rule covers hospitals. Freestanding facilities may publish prices voluntarily, and they will usually quote a cash price over the phone if asked directly.
