1. (A) Enrollment Requirements. In order to voluntarily enroll in a One Care Plan, a MassHealth Standard or MassHealth CommonHealth member must meet all of the following criteria:

   1. (1) be 21 through 64 years of age at the time of enrollment;
   2. (2) be eligible for MassHealth Standard as described in 130 CMR 519.001(B)(1) or 130 CMR 505.001(A)(1) or MassHealth CommonHealth as described in 130 CMR 519.001(B)(5) or 130 CMR 505.001(A)(2);
   3. (3) be enrolled in Medicare Parts A and B, be eligible for Medicare Part D, and have no other health insurance that meets the basic-benefit level as defined in 130 CMR 501.001: Basic- Level Benefit (BLB);
   4. (4) live in a designated service area of a One Care Plan; and
   5. (5) not be subject to any of the exclusions defined in 130 CMR 508.002(C). If a member is enrolled in a One Care Plan and turns 65 years old and is eligible for MassHealth Standard or MassHealth CommonHealth, he or she may elect to remain in the One Care Plan beyond 65 years of age.
2. (B) Selection Procedure. The MassHealth agency will notify members of the availability of a One Care Plan in their service area and of the procedures for enrollment. An eligible member may voluntarily enroll in any One Care Plan in the member’s service area. A service area is the specific geographical area of Massachusetts in which a One Care Plan agrees to serve in its contracts with the MassHealth agency and the Centers for Medicare & Medicaid Services. Service area listings may be obtained from the MassHealth agency or its designee. The list of One Care Plans that the MassHealth agency will make available to members will include those One Care Plans that contract with the MassHealth agency and provide services within the member’s service area.
3. (C) Obtaining Services When Enrolled in a One Care Plan. When a member is enrolled in a One Care Plan in accordance with the requirements under 130 CMR 508.007, the One Care Plan will authorize, arrange, integrate, and coordinate the provision of all covered services for the member. Upon enrollment, the One Care Plan is required to provide evidence of its coverage, the range of available covered services, what to do for emergency conditions and urgent care needs, and how to obtain access to specialty, behavioral health, and long-term services and supports.

4. (D) Disenrollment from a One Care Plan. Disenrollment requests will be effective the first day of the month following the month the request is received by the MassHealth agency or its designee.
