On March 30, 2020, the Centers for Medicare & Medicaid Services released a stunning and far-reaching interim final rule to address the coronavirus (COVID-19) crisis. The rule is a comprehensive set of policy changes designed to—almost overnight—shift the provision of healthcare services to Medicare beneficiaries from face-to-face care to remote care through telehealth. Healthcare providers must quickly understand what the rule entails to ensure that they can continue to treat their needy patient populations while maintaining compliance with Medicare billing and benefit rules.
