Medicare Supplement

Medicare Supplement is private Medicare health insurance, also known as MediGap, that helps pay for medical costs not covered by Original Medicare. You could end up with unexpected high medical bills since there is a 20% gap between what Original Medicare covers and what you will be responsible for if you do not have other Medicare coverage such as Medicare Supplement, Medicare Advantage, or Medi-Cal. MediGap insurance generally helps pay for 20% of the following health care costs:

  • Copayments
  • Coinsurance
  • Deductibles

After you sign up for Original Medicare (Parts A & B) and buy a Medicare Supplement policy, like Plan G or Plan N, Original Medicare pays its 80% share of your Medicare-covered services before a your Supplement insurance pays its 20% share.

Medicare Supplement Open Enrollment

You can buy a MediGap policy without medical underwriting effective the first day of the month that you turn 65 as long as your Part B is active. If you are still working after age 65 and have group health insurance through your employer or union, your initial Medicare Supplement Open Enrollment Period will not start until you are enrolled in both Original Medicare Part A and Part B whether you stop working or not.

Under federal law, you have a six-month Medicare Supplement Open Enrollment Period that begins the month you are 65 or older and actively enrolled in Medicare Parts A & B. Supplement insurance companies must allow you to buy a policy at the best available rate regardless of your health status and cannot deny you coverage during your initial Medicare Supplement Open Enrollment Period. The best available rate depends on several factors, including your age, gender, whether you smoke, your marital status, and where you live. Private insurance companies are not required to sell Medicare Supplement policies to individuals younger than 65 years of age.
