As a Medicare agent, mastering all the different enrollment periods is crucial to ensure smooth enrollment for your clients. It also helps you stay compliant and that is also very important. Understanding IEP vs ICEP is essential to anyone in Medicare sales. Although these two sound similar, they serve distinct purposes and apply to different parts of Medicare.
IEP (Initial Enrollment Period)
First we will go over The IEP. Most agents know that this is the first window of time when someone is eligible to enroll in Original Medicare; specifically Parts A and B.
- Who is eligible to apply: Individuals turning 65 who worked and paid Medicare taxes for a period of at least 10 years (40 quarters) or their spouse or ex-spouse. Those who are under 65 with a qualifying disability, ESRD or ALS are also eligible to enroll.
- Timing: For those who are turning 65; The IEP spans 7 months: it begins 3 months before their 65th birthday, includes their birth month and ends 3 months after the month they turn 65.
- Timing: Individuals who are under 65 and qualify due to a disability; the IEP begins 3 months before the 25th month of their disability benefit entitlement.
Example: If a client turns 65 in May, their IEP runs from February 1st to August 31st.
What beneficiaries can do during IEP
- Enroll in Medicare Part A and/or Part B
- Enroll in a Medicare Part D plan (if they have Part A and/or Part B)
- If they enroll in both Part A & Part B, they may also opt for either a Medicare Advantage (Part C) plan or a Medicare Supplement (Medigap) plan.
ICEP (Initial Coverage Election Period)
When an individual is first eligible for Medicare, the ICEP can specifically be used to enroll in a Medicare Advantage (Part C) plan.
- Who can use the ICEP: Individuals who are first enrolling in both Medicare Part A and B, and want to join a Medicare Advantage plan.
- Timing: Usually, the ICEP coincides with the IEP. However if an individual delays Part B enrollment (e.g., due to employer coverage), the ICEP does not start until they have both Part A and Part B and ends the last day of the month before their Part B coverage begins.
Example 1 (standard case): Client enrolls in A & B to begin July 1. Their ICEP runs from April 1 to June 30.
Example 2 (delayed Part B): Client took Part A at 65; delayed Part B until they retired at 67. Their ICEP begins when they enroll in Part B and ends the last day of the month before Part B becomes effective.
What beneficiaries can do during ICEP
- Enroll in a Medicare Advantage (Part C) plan, with or without drug coverage (MAPD or MA-only).

Important: Always ask clients if they’ve enrolled in both Part A and B before discussing Medicare Advantage options. This small question helps determine whether they’re in their ICEP.
