General Enrollment Period (IEP)
The General Enrollment Period starts on the first of January of every year, and runs through the end of March of the same year (01/01 thru 01/31).
If you did not sign up for Parts A and/or B when you first became eligible, your Initial Enrollment Period (IEP), and you do not qualify for a Special Enrollment Period you may sign up during the General Enrollment Period. However, your coverage will not become effective until July 1st. Additionally, higher premiums may be required as a result of late enrollment; this is applies to both, Part A and B.
