Although many different insurers may offer Medigap Plan A insurance, policies that bear the same letter will have the same coverage no matter who offers them. This standardized approach to Medigap insurance makes it easy to choose the most affordable plan without worrying about missing out on the coverage you need.

Each Medicare Supplement Insurance plan offered in the state of South Dakota covers both the required coinsurance for Medicare Part A and at least a portion of the copays required for Part B. Medigap plans also provide a full 365-day extension of hospitalization coverage in addition to that offered by Original Medicare.

Medigap Plans F and G are available in standard versions and high-deductible versions to allow you a greater measure of flexibility when choosing the right plan for you.

The Medicare Access and CHIP Reauthorization Act of 2015 included provisions that removed access to Medigap Plans C and F for those who were not eligible for Medicare prior to January 1, 2020. Those who were first eligible for Original Medicare before that date, however, can still enroll in these Medicare Supplement Insurance plans if they're available in their area.

For South Dakota Medicare recipients, the most commonly chosen Medigap plans are Plans F, G and N. Affordability and coverage are among the most important features of these plans. The high-deductible versions of Medigap Plans F and G can feature affordable premiums. Plan N offers affordable copays for emergency room visits and routine medical care in your doctor's office.

How Do I Enroll in a South Dakota Medigap Plan?

The best time to enroll in Medigap coverage is during the initial six months starting with the first day of the month you turn 65 and become eligible for Medicare. During this six-month period, you can choose from among any of the available Medigap plans offered in South Dakota by any company. You cannot be turned down for these plans because of pre-existing conditions. Insurers must also offer you the policy you choose at the same premium rates that they would charge a healthy person. This only applies, however, during your initial six months of eligibility.

After your six-month period of open enrollment eligibility expires, insurers can take pre-existing conditions into account when determining the rates you will pay for your Medigap insurance. They may even decline to cover you at all if your medical conditions are deemed to be too risky. For these reasons, it is essential to obtain Medicare Supplement Insurance during the initial six-month eligibility period. Doing so could guarantee that you can get the plan you want at a rate you can afford.

Even if you do not take advantage of the guaranteed eligibility available to you in the first six months after you turn 65, you may still be able to obtain Medigap insurance on the same preferable terms. Guaranteed issue rights are available if you meet one of the following criteria:

  • You have Medicare Advantage, and your plan stops providing service in your area or you move out of the coverage area.
  • You chose Medicare Advantage over Medigap or switched from Medigap to Medicare Advantage and want to change back within a year of this decision.
  • Your Medigap insurance company goes bankrupt.

These are not the only situations in which you may have guaranteed issue rights for Medigap coverage, but they are the most common ways in which you may be eligible for this preferential status in South Dakota.

You may be required to complete a waiting period of six months before you can receive treatment for pre-existing conditions. This is usually waived, however, if you have maintained insurance coverage for these conditions for six months or more prior to switching to Medicare and Medigap coverage.
