Last week, the Centers for Medicare & Medicaid Services (CMS) released the Medicare Outpatient Hospital Prospective Payment System (OPPS) Final Rule for Calendar Year 2025. In addition to annual updates in outpatient hospital Medicare payment rates, this rule finalizes new standards for hospitals and Critical Access Hospitals (CAHs) with obstetric (OB) units regarding maternal quality assessment and performance improvement, the organization, staffing, and delivery of OB care, and staff training on evidence-based maternal health practices. For hospitals and CAHs with emergency services, it adds standards on facility readiness in caring for emergency services’ patients, including pregnant, birthing, and postpartum women. The rule also finalizes new transfer policies for hospitals that mirror the current CAH and Rural Emergency Hospital standards. These Conditions of Participation (CoPs) will be phased in over two years.
