What is hospital price transparency?
Since January 1, 2021, CMS rules have required hospitals to post their standard charges online. The rules implement Section 2718(e) of the Public Health Service Act, added by the Affordable Care Act, which requires hospitals to make public a list of their standard charges each year.
Two disclosures are required. The first is a single machine-readable file covering all items and services. The second is a consumer-friendly display of shoppable services that patients can schedule in advance, which a hospital can satisfy with an online price estimator tool.
What hospitals must publish
The machine-readable file must include, for each item or service:
- Gross charges from the chargemaster.
- Discounted cash prices for self-pay patients.
- Payer-specific negotiated charges, by payer and plan.
- De-identified minimum and maximum negotiated charges.
- Billing codes, descriptions and other required data elements, in a CMS template layout under later updates.
Why hospital price transparency matters
The files are a major public source of hospital negotiated rates by payer. Health plans, employers, consultants and researchers use them to compare what different insurers pay the same hospital, benchmark contracts and study price variation within a market. Commercial teams use them to gauge reimbursement for procedures and drug administration at specific facilities.
Data quality is uneven. Early compliance was low, files vary in structure, and rates written as percentages or formulas are hard to convert into dollars.
How the hospital price transparency rules have changed
CMS raised penalties starting in 2022, scaling them by bed count, and later required a standard template and more data elements. The calendar year 2026 OPPS final rule requires 10th percentile, median and 90th percentile allowed amounts from remittance data when negotiated rates are expressed as percentages or algorithms, plus attestation by a senior official and organizational NPIs, with enforcement of new requirements from April 1, 2026. Rules keep changing, so check the current regulation before relying on a specific requirement.
