CMS Pub. 100-16, ch. 9, § 30.4
Enrollment of Part B-Only Members
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.
