Have you signed up for Medicare?
I haven't.
under what circumstances can I qualify for a SEP?
You could, for example, qualify for a SEP and sign up for Medicare Part B in the 8-month period that begins with the month after your group health plan coverage or the employment it's based on ends.
What if my group health plan coverage ends during my initial enrollment period for Medicare Part B?
then you wouldn't qualify for a SEP.
where can I get more information about enrollment periods for Part B?
You can read the information about general and SEP in our booklet or talk to your personnel office.
In my case, I'm older than 65 and have medical insurance coverage under a group health plan based on my current employment. Do I qualify for a SEP?
You may, yes.
How would affect me if I decide to apply for Medicare part B later?
