New to Medicare? Here’s what you can expect

We're here to help.

If you’re turning 65 or getting close to it, you will likely become eligible for Medicare. As a Michigan Public School Employees’ Retirement System and HAP member, you are automatically eligible to receive medical benefit coverage through our Senior Plus (HMO-POS) Medicare Advantage plan.

HAP is here for our members year after year.

As a Michigan based company, we’re not just near you, we know you. Our experts act like neighbors because they are. With HAP, you’re treated like a neighbor, not a number.

"At 63, I was diagnosed with cancer and given four to six months to live. Whenever I called HAP, I knew that within two minutes I would get a real person on the phone. That’s unheard of in this day and age. HAP insurance let me focus on healing and the customer service was nothing short of amazing. Now, I’m cancer-free."
