Special Enrollment Period (SEP)
There are certain situations when a person can sign up for Part B (and Premium Part A) during a Special Enrollment Period without paying a late enrollment penalty. A Special Enrollment Period is only available for a limited time. If the person doesn’t sign up during their Special Enrollment Period, they’ll have to wait for the next General Enrollment Period and they might have to pay a monthly late enrollment penalty.
Coverage will begin the month after a person enrolls during their SEP.
