CMS Issues Final Rule for 2027 Medicare Hospital Outpatient and Ambulatory Surgical Center Payment Systems

The Centers for Medicare and Medicaid Services, operating within the Department of Health and Human Services, released its final rule with comment period on November 6 2026, establishing payment policies and rates for services furnished in hospital outpatient departments and ambulatory surgical centers. Taking effect on January 1 2027, the regulatory action fulfills statutory mandates under section 1833 of the Social Security Act, which requires annual reviews and adjustments to payment systems to account for evolving medical practices, technological innovations, and updated cost data. The rule covers multiple operational areas, including prospective payment adjustments, quality reporting refinements, administrative compliance evaluations, and prior authorization expansions.

Payment System Updates and Statutory Framework

The regulatory action outlines adjustments to the amounts and factors used to determine payment rates for Medicare services under both the Hospital Outpatient Prospective Payment System and the Ambulatory Surgical Center payment system. Under section 1833(t)(9)(A) of the Social Security Act, the Secretary of Health and Human Services must periodically review payment groups, relative payment weights, and wage adjustments. These modifications reflect recent operational experience and implement specific provisions from the Consolidated Appropriations Act of 2026 concerning off-campus outpatient departments of providers. The agency also announced updates to teaching hospital closures and opportunities for entities to apply for available residency slots.

Quality Reporting Programs and Administrative Compliance

Beyond payment rates, the final rule refines requirements for the Hospital Outpatient Quality Reporting Program and the Ambulatory Surgical Center Quality Reporting Program. Notably, the Rural Emergency Hospital Quality Reporting Program experienced no programmatic changes in this rulemaking cycle. In an effort to streamline oversight, the agency finalized a policy allowing hospital accrediting organizations with deeming authority to assess compliance with specific administrative requirements under the Emergency Medical Treatment and Labor Act during regular accreditation and reaccreditation surveys. Furthermore, the agency finalized the expansion of prior authorization requirements to incorporate additional Botulinum Toxin Injection services and issued a request for information aimed at strengthening the standardization and comparability of hospital price transparency data.

Public Participation and Implementation

While the provisions of the rule become effective on January 1 2027, the Centers for Medicare and Medicaid Services established a public comment period closing on January 4 2027, specifically soliciting feedback on designated portions of the rulemaking. Interested stakeholders, including healthcare providers, legal professionals, and policy analysts, may submit comments through electronic portals or traditional mail. Detailed payment addenda and operational tables are hosted exclusively on the agency website to reduce administrative publication burdens.
