When Does Medicare Supplement Open Enrollment Take Place?

Key Takeaways:

• The Medicare supplement Initial Enrollment Period (IEP) is the first six-months (180-days) of Medicare Part B coverage. During this window you can get any Medicare supplement plan available to you, without any consideration for your medical history. There is no medical underwriting. You can use this calculator to find your IEP.
• After the Medicare supplement IEP, you can enroll in or change Medicare supplement plans any day of the year, as often as you like. However, you must qualify medically to be approved for a new policy. An insurance company can deny your application or charge more for your new policy.
• Some states have special rules that override Medicare for the benefit of the consumer. These states may have special enrollment periods where you can get a policy without medical questions. There may be other limitations or restrictions depending on the state.
• Enrolling in Medicare Part B is what triggers your Medicare supplement policy Enrollment Period.

Over 60 million US citizens are enrolled in Medicare. That’s approximately 20% of the entire US population. But while Original Medicare (Medicare Part A and Medicare Part B) can be incredibly beneficial, Original Medicare was never intended to be stand-alone insurance coverage.

Medicare supplement plans were designed to build on your Original Medicare, reducing your out-of-pocket expenses and providing the security of a maximum out-of-pocket limit on your financial liability.

Because it fills in the gaps in coverage left by Original Medicare, Medicare supplement plans are also referred to as Medigap Plans. Unlike Medicare Advantage Coverage (Part C Medicare), a Medigap plan doesn’t replace your Original Medicare but supplements it, paying for the out-of-pocket costs associated with Original Medicare coverage plans.

What Is a Medicare Supplement Plan?

In simple terms, a Medicare Supplement is health insurance that, as the name implies, supplements one’s Original Medicare plan by covering out-of-pocket costs associated with Medicare Part A and Part B, such as copayments, deductibles, and coinsurance.

Medigap plans are sold by private insurance companies, with Original Medicare beneficiaries being able to choose between ten different Medicare plans (designated by letter), each offering a different level of benefits. We’ve created a helpful Medigap Plans comparison chart if you wish to learn more about them.

Medicare Supplement vs. Medicare Advantage Plans

What many people find confusing is that Medicare Supplement isn’t the same as Medicare Advantage. These two are often mistaken, and while there are several similarities, Medigap and Medicare Advantage (also called Medicare Part C) are two entirely different coverage options. They even have different enrollment periods.

As explained, Medigap supplements your Original Medicare Plan and can be purchased from a private insurance company. The supplement is then secondary insurance to Medicare. That means it is Medicare is primary and makes all decisions.

A Medicare Advantage Plan, however, replaces your Original Medicare coverage with a privatized version of Part A and Part B. As such, the Medicare Advantage Plan becomes your primary insurance coverage and the insurance company makes all decisions to approve or deny your coverage.

We cover Medigap and its differences from a Medicare Advantage plan in more detail in our comprehensive guide to Medicare Supplement insurance you can find under this link.

Who Is Eligible for Medigap Coverage?

To enroll in a Medigap plan you must first be enrolled in Original Medicare, Medicare Part A (hospital insurance) and Medicare Part B (outpatient insurance). That’s perfectly logical, as Medigap supplements your original policy.

In other words, to be eligible to enroll in Medicare Supplemental Insurance, you must first be eligible to enroll in Original Medicare, which you can do if:

• you are 65 years old;
• you have a qualifying disability and receive Social Security Disability Insurance (for at least 2 years);
• you have qualifying diseases, such as amyotrophic lateral sclerosis (ALS) or end-stage renal disease (ESRD).

An important point here is that even if you’re under 65 and enrolled in Medicare, you may be unable to supplement your insurance with Medigap. That’s because federal law doesn’t require offering Medigap policies to people under 65, even if they have disabilities and diseases that qualify them for standard Medicare coverage.

What Is the Medicare Supplement Open Enrollment Period?

Technically, there is not a Medicare Supplement Open Enrollment Period. The term “Open Enrollment” typically refers to the annual enrollment period for a Medicare Advantage plan or Medicare Part D plan.

A Medicare Advantage Plan and Part D prescription drug plans are annual plans. Their benefit structure ends December 31 of each year. The benefits and cost for the following year will be different than the current year. An Open Enrollment Period is required to allow the consumer to shop for a new plan for the following year, based on the new benefits and costs and on a guarantee issue basis.

Medicare supplement plan benefits never change. Because the benefits never change, there is no need for an annual Medicare supplement open enrollment period. You can change plans whenever you wish, but not on a guarantee issue basis.

When Is Medicare Supplement Open Enrollment?

The Medicare Supplement Initial Enrollment Period (IEP) begins on the first day your Medicare Part B is effective. It is a six month period (180-days) starting the day your Medicare Part B coverage begins, during which a person can buy any Medigap policy available to them with a guaranteed issue. you cannot be denied coverage.

That means a Medigap plan insurer can’t deny you supplemental coverage based on your medical history or pre-existing conditions nor charge you higher premiums because of them (a practice called “medical underwriting”). Once your six-month Medigap open enrollment period ends, it never occurs again, although some states have additional open enrollment periods.

Some states allow the consumer a brief window of time annually where they can can get Medicare supplement insurance either around their birthday (a birthday rule state) or around the policy anniversary (anniversary rule state). That period of time can be referred to as the Medigap Open Enrollment Period or Medicare Supplement Open enrollment window. Three states have perpetual open enrollment for Medicare supplement insurance.

What If I Missed My Medigap Open Enrollment Period?

If you miss your six-month Medigap Open Enrollment Period you can still apply for Medicare supplement insurance. If you do not have a recent history of significant critical or chronic illness, you will likely pass medical underwriting and get the Medicare supplement insurance policy you applied for.

While each insurer has different underwriting parameters, some of the medical conditions that can prevent your acceptance would include ongoing or very recent cancer (less than two years cancer free), history of AFIB or heart failure, diabetes with complications, osteoporosis with fractures, rheumatoid arthritis, Alzheimer’s or Parkinson’s or any condition that is requiring more than two medications to treat.

So, what are your options when enrolling outside your six-month enrollment window?

Enrolling Based on Your Guaranteed-Issue Rights

As you plan for your future healthcare needs, keep in mind that if you ever lose your medical insurance through no fault of your own, the Medicare program will provide a special Medigap open enrollment period for you. It is called a Special enrollment Period (SEP).

During a Special Enrollment Period, there are select Medicare supplement policies that will be available to you on a Guarantee Issue basis. These Medicare supplements can be offered by a licensed insurance agent or directly from Medigap insurers.

A guarantee issue SEP can be triggered by any of these events:

• Your existing Medigap plan shuts down;
• Your Medigap insurance company goes bankrupt;
• You were misled by your insurer;
• Your Medicare Advantage plan’s service area changes (or the plan shuts down);
• You enrolled in Medicare Advantage at 65 but decided to switch plans back to Original Medicare within a year (trial rights);
• Your employer coverage that supplemented Medicare ends;
• Your Medigap coverage ends due to no fault of your own.

If any of the above situations apply to you, you should qualify for a Medigap Open Enrollment. What’s more, we can help you find the appropriate Medigap insurer. Request a free quote using our form, and we’ll provide you with the best Medigap policy quote based on your specific needs.

Enrolling in Medigap During the Medicare Open Enrollment Period

If you miss your Medicare Supplement Open Enrollment Period and none of the potential guaranteed-issue situations apply to you, you can also enroll in Medigap during the next Medicare Annual Election Period or Medicare Advantage Open Enrollment Period:

• The Medicare Annual Election Period lasts from October 15 to December 7 each year. During this period, you can switch your Original Medicare plan to Medicare Part C or vice versa and join or leave Medicare Part D coverage (prescription drug policy). You can also choose a Medigap plan to supplement your existing Medicare insurance.
• The Medicare Advantage (Part C) Annual Enrollment Period starts on January 1 and ends on March 31. During this period, Medicare Advantage beneficiaries can switch or drop their Part C plans.

So yes, enrolling in Medigap during “standard” Medicare enrollment periods is possible. In fact, as long as you have Original Medicare and meet other Medicare Supplement requirements, you can enroll in a Medigap policy at any time. However, you can expect to pay more for your insurance if you don’t have guaranteed-issue rights. The insurer can also deny you coverage based on your health problems. A situation that is easily avoided by enrolling during your Initial Open Enrollment Period.

When Is the Best Time to Enroll in Medigap Insurance?

The best time to enroll in a Medicare supplement insurance plan is when you enroll in Medicare Part B. In most states, you can apply for a supplement up to six-months before the start of your Medicare supplement Open Enrollment Period, with a start date the same day your Medicare Part B starts

Therefore, it’s best to spend your time researching the best Medicare Supplement policies and agents before your initial open enrollment window opens. Doing that will ensure you don’t find yourself empty-handed and get your desired Medigap policy at the best price possible.
