Bulletin 440
Interaction Between Medicare and Small Group Health Plans
The Superintendent issues this bulletin to explain the interaction between Medicare and group
health plans, and to remind small group health carriers of the importance of providing employers
and health plan enrollees with accurate information about how Medicare will affect them,
especially when the employer has fewer than 20 employees.
Under federal law, Medicare is secondary to group coverage for active employees and their
spouses if the employer has 20 or more employees.1 This is why employees of those employers
often delay enrollment in Medicare Part B until they retire.
However, if the employer has fewer than 20 employees, Medicare is primary and the employer’s
group health coverage is secondary. This means that the group health carrier can coordinate
benefits, so that its responsibility for payment cannot exceed the portion of the bill that Medicare
does not pay. Furthermore, Maine law also permits carriers to coordinate benefits if the employee
is eligible for Medicare but did not enroll in Part B. This means that if the employee is eligible for
Medicare Part B due to age but chooses to delay enrollment, and the group has fewer than 20
employees, the group plan may decline to cover any portion of a bill that Medicare Part B would
cover, as long as the insured employee, retiree, or dependent has received prominent notice. The
carrier must provide notification to the insured both in the certificate of coverage and when an
insured becomes eligible for Medicare due to age.2
1 Social Security Act § 1862(b)(1) (42 U.S.C. § 1395y(b)(1)).
2 24-A M.R.S. § 2844(1-A)(B)(4).
When the Legislature considered L.D. 616, An Act To Create Uniform Practices for Medicare
Beneficiaries in Small Group Plans, during the last legislative session, the Health Coverage,
Insurance and Financial Services Committee expressed concern that carriers were not adequately
informing employees and retirees about the implications of failure to enroll in Part B at the time
they become eligible for Medicare. Carriers that reduce their benefits when enrollees are
Medicare-eligible but fail to enroll should review and, if necessary, revise both their certificates of
coverage for small group plans and their notifications to Medicare-eligible individuals. Carriers
must clearly articulate in plain, unambiguous language whether the carrier is the primary or
secondary payor for Medicare-eligible individuals and provide examples to explain the difference,
if any, for actively employed individuals and retirees covered under the small group health plan.
