Enrollment of Part B-Only Members

30.4 - Enrollment of Part B-Only Members (Rev. 111, 05-03-13, Effective: 05-03-13, Implementation: 05-03-13) Certain State and local employers do not deduct Federal Insurance Contributions Act (FICA) taxes and as a result their employees may not be entitlement to premium free Medicare/Part A. Employers sometimes would like to offer enrollment in an MA plan for their Part B-only beneficiaries. MAOs may develop plans for Part B-only Medicare beneficiaries who are members of employer/union groups. In permitting such plans, CMS is waiving the existing regulations that prohibit individuals only eligible for Part B from enrolling in MA plans. See 42 CFR 422.50(a) (1). In order to enroll new Part B-only employer/union group members in an MA plan, the MAO must create a separate Part B-only employer/union-only “800 series” plan in accordance with CMS requirements. See Medicare Managed Care Manual, Chapter 2 (Medicare Advantage Enrollment and Disenrollment) for more on enrollment of Part B-only individuals.
