Part D Initial Enrollment Period (IEP)

The Part D Initial Enrollment Period (IEP) is the first opportunity for eligible individuals to enroll in a Medicare Part D prescription drug plan. The IEP is a seven-month period that begins three months before the month of an individual's 65th birthday and ends three months after the month of their 65th birthday. Here are the key features of the Part D Initial Enrollment Period:

• Eligibility: Individuals who are eligible for Medicare Part A and/or Part B are also eligible for Part D. Enrollment in Part D is voluntary, but if you don't enroll during your IEP and don't have other creditable prescription drug coverage, you may face a penalty if you decide to enroll later.

• Enrollment: During your IEP, you can enroll in a Part D plan that is offered in your area. You can choose to enroll in a stand-alone Part D plan to use alongside Original Medicare, or you can enroll in a Medicare Advantage plan that includes prescription drug coverage.

• Coverage Start Date: If you enroll in a Part D plan during your IEP, your coverage will begin on the first day of the month following your enrollment.

• Late Enrollment Penalty: If you don't enroll in Part D during your IEP and don't have other creditable prescription drug coverage, you may face a late enrollment penalty if you decide to enroll later. The penalty is calculated as a percentage of the national base beneficiary premium for each month you were eligible for Part D but didn't enroll.

Example:

John turns 65 in August. His Part D Initial Enrollment Period begins in May and ends in November. If John enrolls in a Part D plan during his IEP, his coverage will start on September 1st.

If John doesn't enroll in a Part D plan during his IEP and doesn't have other creditable prescription drug coverage, he may face a late enrollment penalty if he decides to enroll later. The penalty will be calculated based on the number of months he was eligible for Part D but didn't enroll. For example, if John waits until two years after his IEP to enroll in a Part D plan, and he was eligible for 24 months without enrolling, he would face a penalty of 24% of the national base beneficiary premium. This penalty would be added to his monthly Part D premium for as long as he is enrolled in Part D.
