Medicare’s Enrollment Periods in 2023

Medicare is a federal health insurance program for people who are 65 years or older, certain younger people with disabilities, and people with End-Stage Renal Disease (ESRD). Medicare has different enrollment periods that are crucial for beneficiaries to know in order to avoid late enrollment penalties or coverage gaps. In this blog, we will discuss Medicare’s enrollment periods in 2023, including their dates, eligibility requirements, and what you need to do to enroll or make changes to your coverage.

Medicare’s Initial Enrollment Period (IEP)

Medicare’s Initial Enrollment Period (IEP) is a seven-month period that starts three months before your 65th birthday month and ends three months after it. For example, if your birthday is in May, your IEP starts in February and ends in August. During this period, you can enroll in Medicare Parts A and B, as well as Part D prescription drug coverage, if you choose to. If you miss your IEP, you may have to pay a late enrollment penalty and may have to wait until the General Enrollment Period (GEP) to enroll, which starts in January and ends in March every year.

Medicare’s Annual Enrollment Period (AEP)

Medicare’s Annual Enrollment Period (AEP) is a period from October 15 to December 7 every year, during which you can make changes to your Medicare Advantage (Part C) and Medicare prescription drug (Part D) plans. You can switch from Original Medicare to a Medicare Advantage plan, switch from one Medicare Advantage plan to another, switch from one Medicare prescription drug plan to another, or enroll in a Medicare prescription drug plan if you did not enroll during your IEP. If you are satisfied with your current Medicare coverage, you do not need to do anything during the AEP.

Medicare’s Open Enrollment Period (OEP)

Medicare’s Open Enrollment Period (OEP) is a period from January 1 to March 31 every year, during which you can make one change to your Medicare Advantage plan or switch back to Original Medicare. If you are enrolled in a Medicare Advantage plan during the AEP and find that it does not meet your needs, you have a second chance to make a change during the OEP. However, you cannot use the OEP to switch from one Medicare Advantage plan to another or switch from one Medicare prescription drug plan to another.

Medicare’s Special Enrollment Period (SEP)

Medicare’s Special Enrollment Period (SEP) is a period during which you can make changes to your Medicare coverage outside of the IEP, AEP, or OEP. You are eligible for a SEP if you experience a qualifying life event, such as moving to a new area that is not in your plan’s service area, losing your employer-based health coverage, or becoming eligible for Medicaid. The length of your SEP and the changes you can make depend on the type of SEP you qualify for.

Medicare’s General Enrollment Period (GEP)

Medicare’s General Enrollment Period (GEP) is a period from January 1 to March 31 every year, during which you can enroll in Medicare Parts A and B if you missed your IEP and do not qualify for a SEP. If you enroll in Medicare during the GEP, your coverage will begin on July 1 of that year. However, you may have to pay a late enrollment penalty for Part B if you did not enroll during your IEP and did not have other creditable health coverage.

What is the Most Important Enrollment Period in Medicare?

All Medicare enrollment periods are important, but the most important enrollment period for most beneficiaries is the Initial Enrollment Period (IEP). The IEP is a seven-month period that begins three months before the month you turn 65 and ends three months after the month you turn 65. During this period, you can enroll in Medicare Parts A and B, as well as Part D prescription drug coverage, if you choose to.

It is important to enroll in Medicare during your IEP because if you do not, you may have to pay a late enrollment penalty and may have to wait until the General Enrollment Period (GEP) to enroll, which starts in January and ends in March every year. Additionally, if you do not enroll in Medicare when you are first eligible, you may face gaps in coverage, which could result in high out-of-pocket costs if you need medical care. You can also face late enrollment penalties.

Late enrollment penalties are fees that you may have to pay if you do not enroll in Medicare during your Initial Enrollment Period (IEP) and do not have other creditable coverage, such as employer-sponsored health insurance. These penalties can add up over time and can be a significant expense.

There are two types of late enrollment penalties in Medicare:

  • Part A late enrollment penalty: If you do not enroll in Medicare Part A when you are first eligible and do not have other creditable coverage, you may have to pay a Part A late enrollment penalty. The penalty is added to your monthly Part A premium and increases the longer you go without enrolling in Part A. The penalty amount is 10% of the current Part A premium for every 12 months that you were eligible for Part A but did not enroll.
  • Part B late enrollment penalty: If you do not enroll in Medicare Part B when you are first eligible and do not have other creditable coverage, you may have to pay a Part B late enrollment penalty. The penalty is added to your monthly Part B premium and increases the longer you go without enrolling in Part B. The penalty amount is 10% of the current Part B premium for every 12 months that you were eligible for Part B but did not enroll.

It is important to note that the late enrollment penalties for Parts A and B are lifelong, which means you will have to pay them as long as you have Medicare. Therefore, it is important to enroll in Medicare during your IEP to avoid these penalties and ensure that you have the coverage you need when you need it.

Late Enrollment Penalties Calculation 

Most people do not pay a premium for Medicare Part A because they or their spouse have paid Medicare taxes while working for at least 10 years (or 40 quarters). This is known as having “premium-free” Part A. However, if you or your spouse did not work and pay Medicare taxes for at least 10 years, you will have to pay a premium for Part A.

Here are examples of how the Part A and Part B late enrollment penalties are calculated based on the current premiums for 2023, which are $278 per month for Part A if you worked at least 30 quarters and 506$ if you worked 29 quarters or less. Part B premium is 164.90$ per month. 

Example 1: Part A 278$ late enrollment penalty calculation

Let’s say that you delayed enrolling in Part A for 18 months, and you are now enrolling during the General Enrollment Period (GEP) in 2023. The penalty amount would be calculated as follows:

10% of the current Part A premium ($278) = $27.80

$27.80 x 1.5 (the number of years you were eligible but did not enroll) = $41.70

$278 (current Part A premium) + $41.70 (late enrollment penalty) = $319.70 (total Part A premium)

In this example, your total monthly Part A premium would be $319.70.

Example 2: Part A 506$ late enrollment penalty calculation

Let’s say that you delayed enrolling in Part A for 12 months, and you are now enrolling during the General Enrollment Period (GEP) in 2023. The penalty amount would be calculated as follows:

10% of the current Part A premium ($506) = $50.60

$50.60 x 1 (the number of years you were eligible but did not enroll) = $50.60

$506 (current Part A premium) + $50.60 (late enrollment penalty) = $556.60 (total Part A premium)

In this example, your total monthly Part A premium would be $556.60.

Example 3: Part B late enrollment penalty calculation

Let’s say that you delayed enrolling in Part B for 15 months, and you are now enrolling during the General Enrollment Period (GEP) in 2023. The penalty amount would be calculated as follows:

10% of the current Part B premium ($164.90) = $16.49

$16.49 x 1.25 (the number of years you were eligible but did not enroll) = $20.61

$164.90 (current Part B premium) + $20.61 (late enrollment penalty) = $185.51 (total Part B premium)

In this example, your total monthly Part B premium would be $185.51.

It is important to note that the late enrollment penalty amounts can vary based on the length of time you were eligible for Medicare but did not enroll, and the penalties can accumulate over time. Therefore, it is important to enroll in Medicare during your Initial Enrollment Period (IEP) to avoid these penalties.
