CMS proposes Medicare outpatient-payment changes to reduce site-of-care cost differences

ByDental Info

The proposed changes would affect Medicare payments to hospital outpatient departments and ambulatory surgical centers beginning in calendar year 2027, but rates are not final.

The Centers for Medicare & Medicaid Services proposed changes to Medicare payment policies and rates for hospital outpatient departments and ambulatory surgical centers beginning in calendar year 2027, opening a new phase in the agency’s effort to narrow differences between the two types of care settings.

CMS announced the proposal on July 2, 2026. It is not a final payment rule, and the available announcement does not include a complete schedule of proposed payment rates.

What CMS is proposing

The proposal covers hospital outpatient departments and ambulatory surgical centers, two settings where Medicare pays for care delivered outside a traditional inpatient hospital stay. CMS said it is seeking to revise both payment policies and rates for calendar year 2027.

The agency’s stated goals are to lower costs for beneficiaries, protect taxpayers and strengthen access to care. Those goals describe the rationale for the proposed rule, not results that have already occurred.

CMS has not provided, in the available summary, the full list of services affected or the dollar amounts that would apply to each setting. As a result, the proposal’s effect on particular procedures, facilities or patients cannot yet be determined from the announced material.

Why the site of care matters

Medicare payment differences between hospital outpatient departments and ambulatory surgical centers can influence where health systems choose to provide services. CMS said those differences can encourage systems to move services into higher-cost settings even when there is no clinical need to do so.

That concern puts the proposal at the intersection of Medicare spending, hospital strategy and patient access. If payment rules make one setting more financially attractive than another, health systems may have incentives to organize outpatient services around reimbursement as well as clinical considerations.

For beneficiaries, the practical question is whether any eventual changes alter what they pay for outpatient care or where services are available. CMS linked the proposal to lower beneficiary costs, but the agency has not established that every beneficiary would see lower out-of-pocket expenses. The final impact will depend on the payment policies and rates adopted after the rulemaking process.

The proposal also matters to taxpayers because Medicare payment rates affect federal program spending. The announcement frames the changes as an effort to protect taxpayers while maintaining or strengthening access, but it does not provide a projected savings total in the available summary.

Part of a broader payment-policy effort

CMS announced a related proposal on July 14, 2026, involving Medicare physician payment and value-based-care programs. That separate proposal reinforces the agency’s broader direction toward changes in how Medicare pays for care, but it does not make the July 2 outpatient-payment proposal final.

The two announcements point to payment policy as a central CMS focus, while addressing different parts of the Medicare system. The July 2 proposal concerns hospital outpatient departments and ambulatory surgical centers; the July 14 proposal concerns physician payment and value-based-care programs.

What happens next

The July 2 announcement begins a proposal and rulemaking process rather than putting new rates into effect. Public comment and further rulemaking could change the policies and payment rates before any final rule is issued.

For now, Medicare beneficiaries and health systems should treat calendar year 2027 as the proposed implementation year, not a confirmed date for finalized changes. The final payment schedule, the services covered and the resulting effects on costs and access remain unsettled.
