130 CMR, § 450.216
If termination or suspension of a provider's participation in MassHealth has occurred or is imminent, the MassHealth agency will take such action as may be reasonably necessary or appropriate to prevent or to mitigate injury to members or MassHealth or both, resulting from such termination or suspension. Such action may be taken immediately upon notice to the provider notwithstanding the exercise of such rights as the provider may have to secure administrative or judicial review of the action of the issuing agency, or of the U.S. Department of Health and Human Services, or of the MassHealth agency, or any combination of them. With respect to chronic disease and rehabilitation hospitals and other long-term-care facilities, such action may include an order barring further admissions of members pending final resolution of the issues that prompted such action, or an order that the institution will continue to be paid by the MassHealth agency, for a period specified in the order, for services to members admitted to the facility prior to an order barring new admissions, or prior to such termination. Such action will be reasonably calculated to achieve, so far as possible, the following goals:
