Medicare Insurance Group
The Initial Enrollment Period (IEP) for Parts A and B is 7 months, starting 3 months before the month of your Medicare eligibility and ending 3 months after the month of eligibility. The month of eligibility is the month of your 65th birthday, if you become eligible for Medicare because you are turning 65 years old. Or, if you become eligible due to a disability, your month of eligibility is the 25th month of receiving Social Security Disability Insurance (SSDI)
Note: If you delay your enrollment into Part B, you may have to pay a late enrollment penalty of 10% of the current Part B premium amount for each 12-month period you delayed enrollment. However, if you have coverage from an employer group health plan based on current employment, you may not have to pay the penalty.
If you are 65 years old or older and owe the penalty, you have to pay the penalty for as long as you are enrolled in Part B. If you are younger than 65, have Medicare because of a disability and owe the penalty, the Part B penalty will end when you turn 65 and qualify for Medicare based on age.
Initial Coverage Election Period for Part C
Enrolling in Medicare Part C or a Medicare Advantage (MA) plan is optional. If you want to enroll in a Medicare Advantage plan you must be entitled to both Parts A and B. Your Initial Coverage Election Period (ICEP) to join an MA plan may be 3 months or 7 months as illustrated by the examples below.
