Your coverage will then start in July of that year, and you might need to pay a late enrollment penalty on your Medicare Part B premium for as long as you have Part B coverage.

When you no longer have coverage, you can enroll during the eight-month SEP period that begins in the month after you lose the job or the coverage, whichever comes first.

When Should You Apply for Medicare If You Have Employer Health Coverage?

In addition to this, you’ll have the option to enroll with no punishment during the Special Enrollment Period that follows the end of your boss’ insurance. You can likewise decide to sign up for Part B while still having coverage and pay the premium. On the off chance that your workplace has less than 20 employees, you ought to apply for Part A and Part B when you’re qualified.

In addition to this, ensure that you contact your employer’s benefits administration about what pursuing Medicare will mean for your coverage or Health Savings Account (HSA). You can’t add to an HSA in the event that you have Medicare Part A. Moreover, your chairman can assist you with timing the start and end of your coverage through work and your new health insurance so there’s no gap in your coverage. At the point when your group coverage is finishing, you’ll need to finish documentation and submit it to your Social Security office. In the event that you have questions, ask Social Security.

What Other Times Can You Sign Up?

In case you are qualified because of a disability, you qualify after you have gotten Social Security disability or certain Railroad Retirement Board disability benefits for two years. On the off chance that you have end-stage renal disease (ESRD), you are qualified in the fourth month of dialysis treatment, potentially earlier. And if you have ALS, you qualify that very month your handicap benefits start.

Medicare Open Enrollment

Your initial Medicare enrollment window takes place when you turn 65 years old or are qualified for Medicare through a disability. However, that is not your only chance to choose your coverage. You can use the Medicare open enrollment window to make changes to your Medicare plan. Each year during open enrollment, you can change your coverage. This includes:

  • enrolling in Medicare Advantage
  • enrolling in a Medicare Part D plan
  • switching back to original Medicare from Medicare Advantage

Open enrollment is an excellent time to evaluate your Medicare coverage and make sure it is still the best option for your requirements. It runs from October 15 through December 7 annually.

The changes you make during open enrollment will start on January 1 of the following year. So, if you used open enrollment to choose a new Medicare Advantage plan on November 12, 2020, your new coverage would start on January 1, 2021.

What can you do during open enrollment?

During the open enrollment period, you can:

  • change from a Medicare Advantage plan back to original Medicare
  • change from Original Medicare (Part A and Part B) to a Medicare Advantage (Part C) plan
  • join, switch, or drop a Part D prescription drug plan
  • switch from a Medicare Advantage plan that does not include prescription drug coverage to one that does
  • switch from a Medicare Advantage plan that includes prescription drug coverage to one that does not
  • switch from one Medicare Advantage plan to another

What can’t you do during open enrollment?

Nevertheless, not all plan changes can be made during this time. The main thing you may not be able to do is purchase a Medigap plan. There are only specific times when you can add a Medigap policy to your plan. The enrollment periods for Medigap are:

  • Initial enrollment period. You are qualified to apply for a Medicare plan, and add a Medigap policy during the 3 months before, 3 months after, and month of your 65th birthday.
  • Open enrollment period. If you miss initial enrollment, you can sign up for a policy during the Medigap open enrollment period. If you have already turned 65, this period starts when you enroll in Part B. If you are turning 65, this period runs until 6 months after you turn 65 years old and have enrolled in Part B. During this enrollment period, you are guaranteed to be accepted by a Medigap plan and to get a good rate.

You may be able to buy Medigap plans outside of these windows. However, you will not have the same guarantees. Insurance organizations are not required to sell you a Medigap policy, especially if you are under age 65. Moreover, after your enrollment window, Medigap plans can deny your application or charge you a much higher rate.


Enrolling for Medicare is an essential step as you come close to your 65th birthday. It is also one that can be filled with questions — but you do not have to sign up alone. Both the CMS and the SSA can be valuable resources during your enrollment period. They can assist you in making the correct choices given your circumstance.
