You are Medicare-eligible if you are a legal U.S. resident and one of the following applies to you:

  • You are any age and have a qualifying permanent disability
  • You are any age and have been diagnosed with end-stage renal disease (ESRD)

The ABCDs of Medicare

Original Medicare

Administered by the federal government. Once you decide to join Medicare, you have a few different options. The federal government refers to these Medicare benefits and options as Parts A, B, C and D. No matter which option you choose, the first step is the same: Enroll in Original Medicare, also known as Parts A and B.

Original Medicare doesn't cover everything. Many Medicare recipients choose to buy additional plans from private insurance companies such as Prevea360 Medicare Advantage for alternative coverage options and to spend less out-of-pocket.

Medicare enrollment periods

Annual Enrollment Period (AEP)

You can make changes to your medical and prescription drug coverage every year from Oct. 15–Dec. 7. Your changes are effective Jan. 1.

Initial Enrollment Period (IEP) 

This is the seven-month period in which you can enroll in Medicare for the first time. If you are enrolling for the first time due to disability, your IEP timing is based on your disability date.

Open Enrollment Period (OEP)

Each year, from Jan. 1 – March 31 you can switch from a Medicare Advantage plan to another Medicare Advantage plan, or cancel your Medicare Advantage plan and return to Original Medicare.

Special Enrollment Period (SEP) 

This is a period when Medicare recipients may change medical and prescription drug coverage outside of AEP, if they meet certain requirements and have a qualifying event, such as moving to a new service area or leaving an employer-based plan.
