Most people first enroll in Medicare around age 65. Others make changes during the Annual Enrollment Period each fall. But life does not always follow a calendar.
A Medicare Special Enrollment Period, often called an SEP, is a chance to enroll in Medicare or make certain coverage changes outside the usual enrollment windows. You may qualify after specific life events, such as moving, losing other health coverage, or becoming eligible for certain financial help programs.
The rules can be different depending on the event, the type of Medicare coverage you have, and where you live. Understanding the basics may help you avoid a gap in coverage or a late enrollment penalty.
What is a Medicare Special Enrollment Period?
A Special Enrollment Period is a limited time when Medicare allows eligible people to enroll in or change coverage outside the normal enrollment periods.
There is not just one SEP. Medicare has many Special Enrollment Periods, and each has its own rules. Some allow you to enroll in Original Medicare, which includes Part A and Part B. Others allow you to change a Medicare Advantage plan or Part D prescription drug plan.
Your available options may depend on the reason you qualify. For example, losing employer coverage may give you a different set of choices than moving to a new service area.
What life events may qualify you for an SEP?
Several common situations may create a Special Enrollment Period. Here are a few examples.
- You lose qualifying health coverage. This may include coverage from an employer, a spouse's employer, Medicaid, or another qualifying source.
- You move. Moving outside your Medicare Advantage or Part D plan's service area may allow you to choose a new plan. A move to or from certain institutions, such as a skilled nursing facility, may also qualify.
- You become eligible for Medicaid or a Medicare Savings Program. These programs may help with Medicare costs for people who meet income and resource requirements.
- You qualify for Extra Help with prescription drug costs. Extra Help is a federal program that may help eligible people pay Part D premiums and drug costs.
- Your current plan changes or ends its contract. In some cases, Medicare may provide an enrollment opportunity if a plan leaves your area or has a contract issue.
- You leave incarceration or return to the United States after living abroad. These situations may create a limited enrollment opportunity.
This is not a complete list. Medicare reviews eligibility based on the details of your situation, so it is wise to confirm the rules before making a decision.
How long does a Medicare Special Enrollment Period last?
The length of an SEP depends on why you qualify. Some may last only a short time, while others may continue as long as you remain eligible for a program.
For example, when you lose employer group health coverage after age 65, you may have an eight-month Special Enrollment Period to sign up for Medicare Part B. This timing can be important. COBRA coverage and retiree coverage do not always extend that Part B enrollment window.
If you move and need a new Medicare Advantage or Part D plan, your SEP may begin before the move and continue for a period after it. The exact dates can depend on when you tell your plan about the move and whether you had other coverage before relocating.
Because deadlines may be short, consider acting as soon as you know a qualifying event is happening.
Can you change Medicare Advantage or Part D plans during an SEP?
In many cases, yes. A qualifying life event may allow you to join, switch, or drop a Medicare Advantage plan or Part D prescription drug plan.
For example, if you move to a county where your current Medicare Advantage plan is not offered, you may be able to select a new Medicare Advantage plan available in your new area. You may also have the option to return to Original Medicare and select a Part D plan.
If you return to Original Medicare, you may want to consider a Medicare Supplement plan to help with certain out-of-pocket costs that Original Medicare does not fully pay. However, an SEP for Medicare Advantage or Part D does not automatically give you a guaranteed right to buy any Medicare Supplement plan.
Medicare Supplement availability, underwriting rules, and guaranteed-issue rights can vary by state and circumstance. Outside a protected enrollment window, an insurance company may review your health history before accepting an application.
Does a Special Enrollment Period let you buy a Medigap plan?
Sometimes, but not always. This is an area where people can easily get confused.
Medicare Supplement insurance, also called Medigap, works with Original Medicare. The best-known time to buy a Medicare Supplement plan is your six-month Medigap Open Enrollment Period, which begins when you are at least 65 and enrolled in Part B.
Certain situations may create guaranteed-issue rights for a Medicare Supplement plan. For instance, you may have protections if you leave a Medicare Advantage plan under specific circumstances, such as the plan leaving Medicare or moving out of its service area. The rules and plan choices available under guaranteed issue may vary by state.
If you are thinking about leaving a Medicare Advantage plan, do not assume a Medicare Supplement plan will be available without medical underwriting. It is generally wise to understand your Medigap options before you cancel existing coverage.
What should you do when a qualifying event happens?
Start by gathering documents that show your situation. Depending on the SEP, you may need a letter showing when employer coverage ended, proof of a move, or notice of Medicaid or Extra Help eligibility.
Next, review the coverage choices available in your county. Medicare Advantage and Part D plans can vary by location. Their provider networks, drug lists, premiums, copays, and benefits may also vary by plan, carrier, and state.
If you are considering Original Medicare with a Medicare Supplement plan, look at more than the monthly premium. Consider the benefits of the plan letter, the company's pricing method, your access to doctors, and whether you may need Part D drug coverage.
Do not wait until your coverage ends
When possible, begin looking at your options before your current coverage ends. Waiting could lead to a gap in care, delayed prescription coverage, or fewer plan choices.
Medicare enrollment rules can feel complicated because different events create different deadlines. A little planning may make the transition much smoother.
