This legislation, titled the "SOS: Sustaining Outpatient Services Act," proposes to modify Medicare's payment structure for certain healthcare services. It amends Title XVIII of the Social Security Act to permit specific items and services furnished by off-campus outpatient departments of a provider to be paid under the prospective payment system for hospital outpatient department services . This revised payment methodology would take effect starting in 2027. It specifically targets services where the greatest total amount paid under the physician fee schedule for a particular physician specialty in the preceding year was less than $2,000,000. The bill aims to adjust reimbursement for these designated services, potentially affecting financial sustainability for certain outpatient care providers.
