(1) Coordinated-Care plans (CCPs),
(2) Medicare Savings Accounts (MSAs), and

"Two other types of MA plans characterized by special enrollment are the [Religious Fraternal Society (RFB)] societies which are affiliated with a church and may only enroll RFB members . . . and Part B-only plans which restrict enrollment to beneficiaries who only have Part B of original Medicare . . .."
"defined at 42 CFR 422.4(a)(1), a CCP is a plan that includes a network of providers that are under contract or arrangement with the [Medicare Advantage plan] organization to deliver the benefit package approved by CMS. A CCP must at least
(i) furnish all Part A and Part B services (except for hospice) (42 CFR 422.101(a));
(ii) conduct quality improvement activities (42 CFR 422.152(a)–(b));
(iii) provide sufficient access, as defined by CMS, to services including continuity of care (42 CFR 422.112(a)–(b)); and
(iv) disclose required information about benefits and costs to enrollees (42 CFR 422.111(b)(2)).
CCPs may use mechanisms to control enrollee utilization of services. Mechanisms may include requiring referrals from a gatekeeper (usually the enrollee’s primary care provider (PCP)) or prior authorization for an enrollee to receive certain covered services (42 CFR 422.4(a)(1)(ii))."
