Can I have other types of health insurance?
Yes. In addition to Medicare, you may already have health care coverage such as employer or retiree coverage or another type of health insurance. There are times when your other coverage or health insurance must pay before Medicare pays. Talk to your benefits administrator to see how your other coverage or health insurance works with Medicare.

If you have the Original Medicare Plan, you might also want to buy a Medigap (Medicare Supplemental Health Insurance) Policy. A Medigap policy is a health insurance policy sold by private insurance companies to fill "gaps" in Original Medicare Plan coverage. You might be able to lower your out-of-pocket costs by buying a Medigap policy. Buying a Medigap policy is your decision. You don't need to buy a Medigap policy if you choose a Medicare Advantage Plan.
