Medigap and supplemental insurance are essentially the same thing. Medigap is a type of supplemental insurance that helps cover the gaps in Medicare coverage. It is designed to provide additional financial protection for Medicare beneficiaries by covering expenses such as deductibles, copayments, and coinsurance that are not covered by original Medicare. The terms 'Medigap' and 'supplemental insurance' are often used interchangeably to refer to this type of coverage. It is important to note that Medigap plans are standardized and regulated by the government, so the coverage and benefits will be the same regardless of the insurance company you choose. However, it's always a good idea to compare different Medigap plans and providers to find the one that best meets your specific needs and budget.
