MMC Benefits Handbook
If you are active, for all of the Company healthcare benefits, you must formally enroll to participate. You can enroll for coverage by going to Mercer Marketplace Benefits Enrollment Website via Colleague Connect (https://colleagueconnect.mmc.com). If you are a retiree, you must call the Employee Service Center at +1 866 374 2662, any business day, from 8:00 a.m. to 8:00 p.m. Eastern time, to enroll in retiree medical coverage.
For active employees, you must enroll within 30 calendar days of the date you become eligible or during Annual Enrollment. You may be able to make changes to your elections during the plan year if you have a qualified family status change. For retirees, refer to the "Enrolling/Terminating Retiree Medical Plan Coverage."
