if you retire in say October 2020...and have had insurance through your company health plan...humana...you at time of retiring sign up for plan b....do you then have to wait 9 months without coverage until july of 2021....
No, losing the current employer plan qualifies you for a Special Enrollment Period (SEP). You could set up Part B to start November 1 if you retire in mid-October and the group plan runs through the end of October.
The July start date only applies to those who have to use the General Enrollment Period (GEP) because they don't qualify for a SEP.
Special Enrollment Periods
Once your Initial Enrollment Period ends, you may have the chance to sign up for Medicare during a Special Enrollment Period (SEP). If you're covered under a Group health plan based on current employment, you have a SEP to sign up for Part A and/or Part B anytime as long as:
* You or your spouse (or family member if you're disabled) is working.
* You're covered by a group health plan through the employer or union based on that work.
You also have an 8-month SEP to sign up for Part A and/or Part B that starts at one of these times (whichever happens first):
* The month after the employment ends
* The month after group health plan insurance based on current employment ends.
