Medigap, or Medicare Supplement Insurance, is sold by private companies to cover the 'gaps' in Original Medicare, such as copayments, coinsurance, and deductibles.
The best time to buy a Medigap policy is during the 6-month Medigap Open Enrollment Period, which begins the month you turn 65 and are enrolled in Medicare Part B, guaranteeing you coverage without medical underwriting.
Medigap policies are standardized by the federal government and identified by letters (e.g., Plan G, Plan N), meaning the basic benefits for a specific letter plan are identical regardless of which insurance company sells it.
Constantly worrying about the out-of-pocket costs that Original Medicare leaves behind can take a serious toll on your peace of mind. Enter Medigap. In this straightforward video, we cut through the confusion to explain exactly what these supplemental plans are, how they seamlessly plug the gaps in your coverage, and why securing one might be the smartest financial move you can make for your health.
