It prohibited states from ending coverage for Medicaid beneficiaries enrolled on March 18, 2020 or later and continuing until the end of the COVID-19 emergency.

On April 7, 2020 MassHealth announced the moratorium in an Eligibility Operations Memo. It is also described in FAQs on the MassHealth COVID-19 page, on the Health Connector COVID-19 page and in a March 20 email to Enrollment Assisters.The federal law applies to Medicaid, but MassHealth has extended the protection to the state-funded programs it administers including CMSP and the Health Safety Net.
