Using data from the Centers for Medicare & Medicaid Services (CMS) Hospital Cost Reporting Information System (HCRIS), the Flex Monitoring Team (FMT) produces and reports financial indicators that can be used by CAH stakeholders to benchmark and assess CAH financial performance. These indicators are reported in both the Critical Access Hospital Measurement and Performance Assessment System (CAHMPAS), a free online tool available to CAH executives, State Flex Coordinators, and Federal staff, and also in the annual State Medians Report (a report available to anyone through the FMT website). During the COVID-19 pandemic, CAHs experienced disruptions in services, faced increased costs, and saw an influx of COVID-19 patients. Starting in April 2020, hospitals also received federal Public Health Emergency (PHE) funding. These simultaneous changes not only impacted financial performance, but also influenced the interpretation of these measures and trends. The purpose of this brief is to describe the impact of COVID-19, including federal relief funding (PHE funding), on CAH financial indicators.
