Enroll in a Prominence Health Plan Medicare Advantage Plan

You are not automatically enrolled in Medicare if you turn 65 and have not received Social Security retirement benefits. If you fall into this category, you will need to enroll in Medicare once you are eligible during an Enrollment Period. Enrollment Periods are timeframes that allow you to sign up for Medicare without penalty or additional fees.

How to enroll in a plan

Initial Enrollment Period (IEP)

This is a 7-month window that begins 3 months prior to your 65th birthday and ends 3 months after. For example, if your birthday is in August, your IEP starts in May and ends in November.

General Enrollment Period

The General Enrollment Period falls between January 1 and March 31 each year. This enrollment period is for people who didn’t sign up for Medicare Part A and/or Medicare Part B during their Initial Enrollment Period. Original Medicare coverage would then start in July of the same year.

Annual Election Period (AEP)

Unless you are able to participate in another enrollment period, this is the only time that you can enroll or change your Medicare plan for the following year. Medicare members typically use this time to join Medicare Part C or Medicare Part D, also known as Medicare Advantage Plans, if they did not do so previously. The AEP takes place each year between October 15 and December 7.

Medicare Advantage Open Enrollment Period (MA/OEP)

The Medicare Advantage Open Enrollment Period takes place between January 1 and March 31 of the year of coverage. The Medicare Advantage Open Enrollment Period is an opportunity to disenroll from a Medicare Advantage plan and return to original Medicare or switch to another Medicare Advantage plan.
