To help eligible retirees supplement their Medicare health benefits, the The University of Maine System (UMS) recently conducted an extensive review of its group health plans compared to the health insurance options now available in the individual market. Their study showed the individual market can offer more options and flexibility in benefit choices, which could potentially cost retirees less for comparable or better health and prescription drug coverage.

By December 31, 2020, UMS Medicare-eligible retirees and their Medicare-eligible dependents will need to select and enroll in individual Medicare coverage to replace their current group health plan, for coverage to be effective January 1, 2021.

Medicare-eligible retirees who don’t meet the December 31 deadline will continue to be covered by Original Medicare (Parts A and B), if enrolled.

As a Medicare-eligible retiree of The University of Maine System, you can experience health care coverage in a new way – with more choices, greater flexibility and better value.

Use this website as a resource to learn and prepare for enrollment in health care coverage through Aon Retiree Health Exchange, which begins January 1, 2021. Let Aon help you make the move to a Medicare plan easy and hassle-free.
