Basics of Medicare supplement insurance
Medicare supplement insurance, also called Medigap, is private health insurance. You must have both Medicare Part A and Part B before you apply for this insurance. Medicare supplement (MedSup) policies help pay amounts not covered by the Original Medicare Plan. Only you can decide which policy best meets your needs. MedSup policies are “standardized” — the plans are identified by letters A through N. Two plans with the same letter are identical, no matter which companies sell them. The only difference is the cost. A Medicare supplement policy covers only one person. If you and your spouse both want MedSup coverage, you must buy two separate policies. No MedSup policy covers: long-term care (such as care in a nursing home), vision or dental care, eyeglasses, prescription drugs, private-duty nursing or hearing aids.
