The Medicare Program is the federal health insurance program for:
People age 65 or older.
People under age 65 with certain disabilities.
I believe these qualifiers would be covered by the statement about certain disabilities.
Medicare Part A (Hospital Insurance)
Medicare Part B (Medical Insurance)
Medicare Part C
Medicare Part D (Prescription Drug Coverage)
Medicare prescription drug coverage is available to everyone who will or currently is enrolled under Medicare Part A and/or Part B. To enroll in a Medicare Part D prescription drug plan, you must join a stand-alone Part D plan or a Medicare Advantage plan that includes prescription drug coverage. Even if you don’t take prescriptions now, you should consider joining a Medicare drug plan or a Medicare Advantage Plan (Must be enrolled under Part A and Part B) with drug coverage to avoid a penalty.
Medicare Supplemental Plan AKA Medigap
Medicare Supplemental Insurance is designed to cover the gaps in Original Medicare. Medicare Supplemental plans are also known as Medigap plans. They are offered by most private insurance. Medicare Supplemental plans offered by the carriers, only vary by the price for the plan. All the carriers cover the Medicare Supplemental plan the same way. You will have access to all physicians who participate with Medicare nationwide. Some policies offer value added services. All Medicare Supplemental Plans must offer a set of basic benefits, but some Medicare Supplemental plans are designed to offer more. Original Medicare pays for a sizable portion of the healthcare services you need, but you are responsible for paying some portion, including copays, deductibles, and coinsurance.
Please be sure to have credible prescription coverage when enrolling under a Medicare supplemental plan to avoid any possibility of a part D late enrollment penalty.
