CMS posts proposed 2027 Medicare payment rule for hospitals and surgery centers

The proposed rule covers 2027 Medicare payments for hospital outpatient departments and ambulatory surgical centers, as well as quality reporting, star ratings and hospital price transparency.

The Centers for Medicare and Medicaid Services has published a proposed rule that would set the framework for calendar-year 2027 Medicare payments to hospital outpatient departments and ambulatory surgical centers across the United States.

CMS published the proposal Aug. 4, 2026, as part of the annual Medicare payment-rule cycle. The notice covers the hospital outpatient prospective payment system and the ambulatory surgical center payment system, along with federal programs involving hospital quality reporting, overall hospital quality star ratings and hospital price transparency.

The action begins the process for setting the rules that will govern the 2027 program year. It does not, however, establish final Medicare payment rates or make the proposal’s policies binding.

What CMS is proposing

The proposed rule addresses two Medicare payment systems. One is used for hospital outpatient services, while the other applies to services provided in ambulatory surgical centers. The systems govern payment policy for care delivered outside the inpatient hospital setting.

The proposal also includes quality reporting programs. Those provisions concern information hospitals report through federal programs used for quality oversight and public reporting. CMS separately addresses overall hospital quality star ratings, which present hospital performance information through a standardized rating system.

Hospital price transparency is another part of the notice. The proposal addresses requirements for hospitals to make pricing information available to the public. That places payment policy, quality information and pricing disclosure in the same annual rulemaking package, although each area involves different requirements and policy questions.

Why the proposal matters

The proposed policies could affect Medicare payment levels for participating hospitals and ambulatory surgical centers during calendar year 2027. They could also affect the reporting obligations those providers must meet, the information incorporated into overall hospital star ratings and the requirements hospitals follow when making price information public.

For hospitals and surgery centers, those decisions are relevant to planning for the next Medicare program year. Payment rules help determine how participating providers are paid for covered outpatient services. Reporting and transparency rules can shape the information providers must prepare, submit or publish under federal programs.

The quality provisions also matter because they concern how hospital performance information is reported and presented. Star ratings give the public a standardized way to view hospital quality information, while quality-reporting requirements determine which information hospitals provide through federal oversight and public-reporting programs.

The price-transparency provisions address a separate public-information issue: what hospitals must make available about prices. Any change to those requirements could affect the information that is publicly posted by hospitals during the 2027 policy period, though the proposed rule itself does not make a final change.

Because the rule applies to Medicare payment systems and hospital programs used nationally, its implications extend beyond a single provider or state. Medicare-participating hospitals and ambulatory surgical centers will be watching both the proposed payment policies and the related reporting, rating and disclosure provisions as CMS moves toward a final rule.

What happens next

The Federal Register notice distinguishes the proposed calendar-year 2027 policies from the later publication of a final rule. CMS must complete that final-rule stage before the payment rates and requirements for 2027 become binding.

As a result, the proposed rule does not establish a specific dollar increase or decrease for hospitals or ambulatory surgical centers. It also does not guarantee that every provision will appear unchanged in the final rule. The final rates and final policy decisions remain pending.

The Aug. 4 publication is therefore a significant step in the annual process, but it is not the final decision on 2027 Medicare payments or hospital requirements. Providers, patients and others following Medicare policy will need to look to CMS’s subsequent final rule for the binding policies that ultimately govern the calendar year.
