Facts on Original Medicare

Medicare Part A is hospital insurance. It includes hospital care, home health care, skilled nursing care, surgery, and other inpatient health services.

Meanwhile, Medicare Part B covers a range of medically necessary services and preventive services—including lab tests, vaccinations, clinical research, ambulance services, durable medical equipment, mental health care, and other outpatient services.

However, there is a long list of things that are not covered by Original Medicare – such as long-term care, dental care, vision care, foot care, hearing aids, and more. In addition, both Medicare Parts A and B come with cost-sharing fees and other out-of-pocket costs that you will have to cover yourself.

For example, even though you don’t have to pay a monthly premium for Medicare Part A, you are still responsible for each benefit period and all co-payments per benefit period.

Similarly, Part B comes with a monthly premium of at least $170.10 (and up to $578.30, depending on your income) — in addition to the $233 annual deductible and 20% coinsurance split. These are all costs that you must pay out of pocket before Original Medicare pays anything.

Some benefits are common to all supplemental insurance plans. For example, each Medigap plan covers Medicare Part A co-insurance costs and extends hospital coverage for an additional 365 days after Medicare benefits end. However, coverage of other items such as coinsurance for skilled nursing care or the Part B deductible will vary depending on the Medigap plan you choose.

As a result, it is difficult to say how much your Medigap plan will cost because pricing will vary significantly based on your plan type, insurance provider, state, age, marital status, and other factors. Generally, however, premiums for Medicare supplemental insurance range between $50 and $500 per month, while the national average monthly premium stands at about $150.

Do you need Medicare supplemental insurance?

While Medicare supplement insurance isn’t cheap, it can be right for seniors who expect to be heavy users of healthcare. Medigap can also come in handy if you want coverage for services not covered by Medicare.
