Turning 65
New to Medicare? Here’s what you can expect
If you’re turning 65 or getting close to it, you will likely become eligible for Medicare. As a Michigan Public School Employee Retiree and our member, you are automatically eligible to receive medical benefit coverage through our Senior Plus (HMO-POS) Medicare Advantage plan.

We're here to help.
The process:
- You’ll receive a reminder from us, 30-90 days before your 65th birthday.
- When you turn 65, contact ORS to start your enrollment into Medicare Advantage.
- New members will receive a welcome kit.
- Keep your red, white and blue Medicare card somewhere safe, as you’ll only need your Health Alliance Plan ID card.
- No monthly contribution.
If you are Medicare eligible and haven’t enrolled in Medicare Parts A and B, it’s important that you contact your local Social Security office to enroll. To ensure a smooth transition to your new plan with us, this should occur within the three months prior to your birthday month.
If you do not enroll in Original Medicare and Parts A and B, you will no longer be eligible for our coverage. It will end the first of the month in which you turn 65.
If you have any questions, please call our customer service team at (800) 801-1770 (TTY: 711).
