Supplement Insurance

Medicare Supplement insurance plans, also known as Medigap, help pay for medical costs not covered by original Medicare. There is a gap between what Medicare covers and what you as the beneficiary is responsible for when getting medical services. You will need more medical care as you age and could end up with high unexpected costs if you do not have supplemental insurance to cover the 20% percent portion of your Medicare bills. Medicare supplement insurance generally helps pay for the following health care costs:

  • Copayments
  • Coinsurance
  • Deductibles

After you sign up for original Medicare (Parts A & B) and then buy a Medicare Supplement plan, original Medicare will pay its share of the Medicare-Approved Amount for covered health care costs. Then, your Supplement insurance will pay its share.

When is Medigap Open Enrollment?

You can buy a Medigap plan without medical underwriting the first day of the month that you turn 65 and enroll in Medicare Part B, with some exceptions. If you have group health insurance through an employer or union, your Medigap open enrollment period will start when you sign up for Part B.

Under federal law, you have a six-month open enrollment period that begins the month you are 65 or older and enrolled in Medicare Part B. During your open enrollment period, Medigap companies must sell you a policy at the best available rate regardless of your health status, and they cannot deny you coverage. The best available rate may depend on a number of factors, including your age, gender, whether you smoke, your marital status, and where you live.

You may run into problems if you try to buy a Medigap policy outside a protected enrollment period. For instance, companies can refuse to sell you one or impose certain medical requirements. If a company does agree to sell you a policy, you may need to pay a higher monthly premium and be subject to a six-month waiting period before the Medigap will cover pre-existing conditions. Be sure to contact Medigap insurers in your state to learn if they will sell you a Medigap policy outside protected enrollment periods.

If you have End Stage Renal Disease (ESRD), you may not be able to buy a Medicare Supplement policy until you turn 65 years of age. Federal law does not require insurance companies to sell Supplement insurance policies to people under age 65.
