The Centers for Medicare & Medicaid Services released a second, sweeping interim final rule in response to the coronavirus (COVID-19) pandemic on April 30, 2020. Building on the agency’s unprecedented March 31, 2020 regulation, which prioritized distancing patients from their care teams in response to the public health emergency, this second round of policy changes emphasized easing COVID-19 testing restrictions and expanding health system capacity for a phased reopening of the country.
