Hospital price transparency: how to look up prices before a procedure

Why prices are public now

For years it was nearly impossible to learn what a hospital would charge before you got care. Federal rules have changed that. Since 2021, hospitals have had to post their prices online, and most health insurers have had to offer online cost tools. The data is far from perfect, but for planned care it can help you avoid a big surprise and compare options.

What hospitals must post

Under the CMS Hospital Price Transparency rule, every hospital must post two things on its website:

• A machine-readable file. This is one large data file, in a standard CMS format, listing the hospital's standard charges for its items and services. It includes gross charges (the list price), the discounted cash price, the rates negotiated with each insurer, and the lowest and highest negotiated rates.
• A consumer-friendly list of shoppable services. This must cover at least 300 services you can schedule ahead, such as imaging, lab work or a joint replacement, in plain language and grouped with related services. Hospitals that offer fewer than 300 such services must list all of them.
• Instead of the shoppable list, a hospital may offer an online price estimator tool that tells you what it expects you to owe.

What changed in 2026

CMS tightened the rule in its 2026 hospital outpatient payment rule, finalized in November 2025 under an executive order on health care price information. The changes took effect January 1, 2026, and CMS began enforcing the new data requirements on April 1, 2026.

• When a negotiated rate is set as a percentage or formula rather than a dollar amount, hospitals must now show the median amount actually paid, plus the 10th and 90th percentile amounts, based on real payment records.
• Hospitals must attest that their file is complete and accurate, and name a senior official responsible for the data.
• A hospital that waives its right to a hearing can get a 35% cut in a penalty, but not for failing to post the file or the shoppable services at all.

What insurers must show you

A separate set of rules, called Transparency in Coverage, applies to most private health plans. They must post large data files of their negotiated rates, and they must offer you an online self-service tool, or paper information on request, that estimates your own cost sharing for covered care with in-network providers.

On October 5, 2026, federal agencies issued final updates to these rules. Starting with plan years that begin on or after January 1, 2027, plans must also give you the same cost-sharing estimate over the phone if you ask. The insurer data files will move to quarterly updates and a simpler structure in phases through 2028.

How to use the tools before a scheduled procedure

Price tools work best for care you can plan, not emergencies. A simple approach:

• Ask your doctor for the name of the procedure and its billing code (often a CPT code). Codes make searches far more accurate.
• If you have insurance, start with your insurer's cost estimator, which should reflect your deductible and what you've already paid this year.
• Check the hospital's shoppable services page or price estimator, and look up one or two other in-network hospitals or surgery centers for comparison.
• If you're uninsured or paying cash, compare discounted cash prices and ask each provider for a good faith estimate, which you have a right to under the No Surprises Act.
• Ask whether the price includes the surgeon, anesthesia, imaging and follow-up visits, which are often billed separately.

Limits of the data

Posted prices are a starting point, not a promise. A posted rate may not include every doctor who treats you. The machine-readable files are huge and hard to read without software. Compliance has been uneven, and some files have been incomplete or hard to find. What you actually owe also depends on your deductible, coinsurance and whether every provider involved is in your network.

Use the numbers to ask better questions, and get your own estimate in writing before a planned procedure when you can.

Enforcement and what's next

CMS can issue warnings, require a corrective action plan, or impose civil money penalties on hospitals that don't comply, and it publishes those penalties. If you can't find a hospital's prices online, you can submit a complaint to CMS through the hospital price transparency section of CMS.gov.

Another agency has stepped in, too. On October 5, 2026, the Federal Trade Commission sent warning letters to 24 large health systems saying that incomplete, inaccurate or late pricing could be deceptive or unfair under the FTC Act, and that following CMS's rules is not a safe harbor. As of late October 2026, the FTC had not named the systems. More changes are likely, so check a hospital's current tools rather than relying on older reports.

The bottom line

For planned care, ten minutes with your insurer's estimator and a hospital's price page can show you whether one option costs far more than another. Prices for the same scan or procedure can vary widely between hospitals in the same area. This is general information, not financial advice; your plan documents and written estimates are what count.
