As a U.S. citizen, you are generally eligible for Medicare benefits when you turn 65, but don’t assume your Medicare card will automatically arrive. If you receive Social Security disability or Railroad Retirement Board benefits, you will be automatically enrolled. But if not, you must be proactive! That’s why it’s important for everyone to get to know more about Medicare open enrollment and the different enrollment periods that might apply as they enroll or make changes in coverage.

When we talk about the Medicare enrollment period, there are actually four periods that come into play:

  1. Initial Enrollment Period (IEP): Starts three months before the month you turn 65 through three months after the month you turn 65.
  2. Medicare Advantage Open Enrollment Period (MAOEP): January 1 to March 31.   
  3. Annual Enrollment Period (AEP): October 15 to December 7.
  4. Special Enrollment Period (SEP): This open period is based on qualified life events.

What Changes Can Be Made During the Annual Enrollment Period

During the Medicare Annual Enrollment Period, which runs from October 15 to December 7, people can make changes to their Medicare coverage choices that will go into effect the following January 1. The AEP is your time to join a Medicare Advantage (Part C) plan or add a standalone Medicare Part D plan for prescription drug coverage if you’re currently enrolled in Original Medicare, or Medicare Part A and B. If you already have Original Medicare and Medicare Part D, during this period, you can join a Medicare Advantage plan or switch or drop your prescription drug coverage.

For people who already are covered by a Medicare Advantage plan, the AEP is a chance to switch to another Medicare Advantage plan, add a Medicare Part D plan (if your plan doesn’t already include prescription drug benefits), or switch back to Original Medicare.

Tips to Maximize Medicare Initial Enrollment

Enrollment periods will vary by individual. If you are enrolling in Medicare for the first time, you will have an Initial Enrollment Period.  (IEP) For most people, this period starts three months before the month in which you turn 65 to three months after you turn 65. 

For example, if you turn 65 in July, you can apply three months before your birthday month, so April, May, and June. And your IEP continues through 3 months after your birthday, so August, September, and October. If you happened to be born on the first of the month, you could enroll four months before your birth month and up to two months following your birth month.

If you are eligible for Part A but miss your IEP window, you can still apply at any time, and receive retroactive benefits for six months, if it has been six months since your eligibility date. 

You’ll want to enroll as early as possible to ensure your benefits start in your birth month. Remember, signing up after your 65th birthday month will create a delay in when your Medicare coverage starts. 

You can apply for your Medicare benefits online at www.socialsecurity.gov or on the phone by calling 1-800-772-1213. They can answer your questions about eligibility and will help you enroll. The Medicare.gov website also has a great tool to help you determine if and when you are eligible for Medicare called the Medicare Eligibility Tool, which will give you an estimate of when you are eligible and your estimated premium amount.

If you work for a company that has 20 or more employees, you may want to enroll in Medicare even if you are covered under your employer’s health plan. If your Part A plan is free of any premium, this can add another level of coverage for you. Your employee coverage becomes your primary insurance, and your Medicare Part A becomes secondary. Medicare enrollment for Part B is not premium-free and could be an expensive option. If your employer has less than 20 employees, you may be required to sign up for Medicare at age 65. That would become your primary insurance, and Medicare Part B enrollment becomes a better option.

What Happens After the Annual Enrollment Period

Special Enrollment Periods (SEP) provide additional enrollment periods outside of your Initial Enrollment Period and can be beneficial for people who have missed the Annual Enrollment Period — but not everyone will qualify for this special period to make changes to their Medicare coverage or enroll in a plan.

Qualifications for SEPs can vary based on your specific situation, but here are some common reasons:

  • Relocation: If you have moved to an address outside of your current plan’s service area, you may qualify for a SEP.
  • Loss of coverage: If you have lost your existing health coverage, such as employer-sponsored health insurance, you may qualify.
  • Assistance: If you become eligible for other assistance programs such as Medicaid or Extra Help prescription drug costs. You may qualify.
  • Other: Some other special circumstances, such as a natural disaster or being incarcerated, may make you eligible for a SEP.
