Since 2021, every hospital in the United States has been legally required to publish a machine-readable file listing what it charges for every item and service, including the discounted cash price and the rate negotiated with each insurer. Compliance was patchy for years and the files were built to be unreadable. That changed: CMS standardized the format, added required fields, tightened the attestation, and began enforcing the 2026 requirements on April 1, 2026. The files are now usable, and this is how to use one.
Key takeaways
- Every hospital must post a machine-readable file (MRF) of standard charges in a CMS-specified format, plus a consumer-friendly display of shoppable services. The MRF is the one with the real numbers.
- The 2026 rule (effective January 1, enforced from April 1, 2026) requires the CMS v3.0 schema, dollar amounts where charges are based on percentages or algorithms, and a strengthened accuracy attestation.
- The columns that matter for a cash patient: description, billing code, gross charge, discounted cash price, and the payer-specific negotiated charges with their minimum and maximum.
- CMS has already issued a request for information on further standardization for 2027; the files are getting more comparable, not less.
Step by step
- Find the file. Hospitals must post a text file at the root of their website (/cms-hpt.txt) that points to the MRF location, and must include a footer link to price transparency. If both fail, search the hospital name with “machine-readable file” or “standard charges.” The CMS Hospital Price Transparency page links to enforcement actions if a hospital simply does not comply.
- Download it, and expect it to be large. MRFs are CSV or JSON files that can run to hundreds of megabytes. A spreadsheet program will struggle past a million rows; a free CSV viewer, a database tool or a few lines of Python handle them. Third-party services also index these files into searchable form; they are a reasonable shortcut for a single lookup.
- Get your code. Ask the surgeon's office for the CPT code(s) and, for inpatient surgery, the DRG. Filter the file on the code column (the v3.0 schema names it explicitly and includes the code type). Description text searches work but miss variants.
- Read the row. You will see a gross charge (the chargemaster list price), a discounted cash price, and a set of payer-specific negotiated charges, each labeled with the insurer and plan. Newer files also show the minimum and maximum negotiated charges and, where the negotiated rate was a percentage or formula, the dollar amount it works out to.
- Understand the setting. The v3.0 schema records whether a charge applies in the inpatient or outpatient setting; the same code can appear in both. Match it to how your procedure will actually be performed.
- Add the professionals. The hospital MRF covers the hospital. The surgeon and anesthesiologist may bill separately unless the file explicitly bundles them. Use the Medicare fee schedule to estimate those lines.
- Compare across hospitals. Repeat for two or three hospitals in your area and one transparent cash-bundle center elsewhere (see state price spread). Then compare the total to an international package.
What one procedure looks like inside a hospital price file (illustrative)
What the columns actually mean
Gross charge
The chargemaster list price. Almost nobody pays it, but uninsured patients are billed it unless they ask for the cash price or qualify for financial assistance. Our chargemaster explainer covers why it exists.
Discounted cash price
What the hospital charges a self-pay patient who asks. It is often below several negotiated rates, which is why insured patients sometimes pay cash for imaging and outpatient procedures.
Payer-specific negotiated charge
The contracted rate with each named insurer and plan. Since 2025 hospitals must express these in dollars where possible; the 2026 rule extended that to percentage- and algorithm-based contracts.
De-identified min and max
The lowest and highest negotiated rates across all payers, without naming which. Useful for seeing the spread at one hospital.
Modifiers and setting
Codes carry modifiers and an inpatient/outpatient flag. The v3.0 schema makes these explicit fields; older files buried them in description text.
Attestation
A hospital officer must now affirm the file is complete and accurate. It is the field that turns a data dump into a document someone is accountable for.
What to do with the number
A cash price from the MRF is a real, published price that the hospital has attested to. Bring it to the financial counselor and ask for it in writing. If your local hospital's cash price is far above the Medicare rate and above what a transparent surgery center elsewhere publishes, you have the evidence for a negotiation, a domestic trip, or an international package, and our negotiation vs travel comparison walks the three. getmedicalquotes.com covers how to get comparable written quotes from clinics abroad.
Where Colombia sits, and how to read it
Colombia appears in the middle-to-low band on almost every row of this table, and for North American patients it carries a logistics advantage the cheaper Asian rows cannot match: three to five hours of direct flight from Miami, Houston, Atlanta, New York and Fort Lauderdale, and a same-or-adjacent time zone for follow-up calls. The World Health Organization ranked Colombia's health system #22 in the world and #1 in the Western Hemisphere in its 2000 World Health Report; that ranking is now a historical benchmark rather than a current league table, but it reflects a system that was built on universal coverage and a strong private hospital tier. Six Colombian hospitals hold Joint Commission International accreditation as of 2026 — accreditation is hospital-level, and it does not extend to freestanding clinics or to individual surgeons.
Two verification anchors matter more than any price. First, any Colombian physician can be checked in the national ReTHUS registry (rethus.gov.co), which confirms licensure and specialty. Second, the facility should be able to show its habilitación (operating license) for the specific service line. A low number from a facility that cannot produce either is not a bargain; it is an unpriced risk.

Frequently asked questions
Where do I find a hospital's price transparency file?
Hospitals must post a text file at the root of their website (cms-hpt.txt) pointing to the machine-readable file and include a footer link to price transparency. Searching the hospital name with machine-readable file also works.
What changed in the 2026 hospital price transparency rule?
The CY 2026 rule requires the CMS v3.0 file schema, dollar amounts for charges based on percentages or algorithms, and a strengthened accuracy attestation, effective January 1, 2026 with enforcement from April 1, 2026.
Is the discounted cash price what I will pay?
It is the hospital's published self-pay price for that item and a strong basis for a written estimate, but the final bill depends on what is actually performed and whether surgeon and anesthesia bill separately.
Can insured patients use the cash price?
Sometimes. For imaging and some outpatient services the cash price can be lower than the negotiated rate; paying cash means the amount usually does not count toward your deductible.
What if a hospital has not posted a file?
CMS can issue corrective action requests and civil monetary penalties and publishes enforcement actions. Report non-compliance through the CMS Hospital Price Transparency page.
