Medigap, also known as Medicare Supplement Insurance, helps cover some of the healthcare costs that Original Medicare doesn't cover, such as copayments, coinsurance, and deductibles. It may also cover certain services that Medicare doesn't fully cover. However, it's important to note that Medigap policies generally don't cover long-term care, vision or dental care, hearing aids, eyeglasses, or private-duty nursing. The coverage provided by Medigap plans can vary, so it's essential to carefully review the specific benefits offered by each plan. Additionally, Medigap policies are sold by private insurance companies, so the availability and cost of plans may vary depending on your location and the insurance provider. It's advisable to compare different Medigap plans to find one that best suits your healthcare needs and budget.
