Starting January 1, 2026, hospitals must post actual prices based on real claims data—not vague estimates. The Centers for Medicare & Medicaid Services (CMS), the federal agency that oversees Medicare, finalized this rule in November 2025 to force hospitals to disclose what they actually charge across different insurance plans. This closes a loophole that let hospitals hide real prices behind fake "estimated allowed amounts." The rule affects roughly 6,000 Medicare-participating hospitals nationwide and applies to any procedure they perform, making price comparison possible before you seek care.

The "estimated allowed amount" loophole
Before this rule, hospitals could post placeholder amounts that bore no relation to what insurers actually paid. A procedure might be listed at $50,000 while real claims showed it ranged from $12,000 to $80,000 depending on which insurance plan negotiated the rate. The prior rule permitted hospitals to post vague estimates for payer-negotiated rates; the 2026 rule requires actual median and percentile figures, closing the disclosure gap that previously obscured true costs from patients. Without real numbers, patients couldn't decide whether to seek care elsewhere or know what their own insurance plan might actually pay.
What hospitals must disclose—and when
Hospitals must now disclose median allowed amounts, 10th percentile allowed amounts, and 90th percentile allowed amounts calculated from the prior 12 to 15 months of real insurance claims. This gives you the middle price (median), the cheaper range (10th percentile), and the expensive range (90th percentile) for each service.
Additionally, a hospital's CEO or designated senior official must now attest in writing that all posted prices are "true, accurate, and complete," creating personal accountability for data integrity. The rule became effective January 1, 2026, but CMS delayed enforcement until April 1, 2026, giving hospitals three months to update systems and validate data.
How to use hospital prices to make decisions
Standardized, percentile-based price data allows patients to estimate care costs beforehand and compare prices across hospitals, supporting informed decision-making and market competition on price. Before elective surgery or a planned procedure, you can now look up the expected range at multiple facilities and negotiate with your chosen hospital.
The data is released in machine-readable files that hospitals must post; price-comparison websites are beginning to aggregate and display this information in simpler formats. If you're uninsured or paying out-of-pocket, knowing the percentile range helps you budget and ask whether you qualify for financial assistance.
What happens if hospitals don't comply
Hospitals failing to comply face civil monetary penalties of $10 per bed per day (minimum $300/day, maximum $5,500/day), or approximately $2 million annually for larger facilities. CMS has already issued over $2 million in penalties to hospitals that violated earlier price transparency rules, showing the agency's commitment to enforcement.
If you discover a hospital posting vague estimates or no prices at all after April 1, 2026, you can report it to CMS. Enforcement begins immediately on that date, so noncompliant hospitals face financial pressure to update their disclosure systems.
Frequently Asked Questions
Where do I find hospital prices?
Hospitals must post prices in machine-readable files on their websites, typically in a folder labeled "price transparency" or "patient pricing." Some prices also appear on third-party comparison websites.
Does this rule apply to my hospital?
The requirement covers all hospitals that participate in Medicare, affecting approximately 6,000+ facilities across the country regardless of size or rural status.
What if my hospital hasn't posted prices yet?
After April 1, 2026, you can report noncompliance to CMS. Hospitals face penalties of up to $5,500 per day, so enforcement should prompt rapid updates.
