Medicare
Medicare Advantage and Original Medicare are not the same product
One is a federal fee-for-service program. The other is a private plan that packages benefits under contract with Medicare. The difference shows up in networks, drugs, and what you pay out of pocket.
People turning 65 often hear both names in the same sentence and assume they are two labels for one benefit. They are not. Original Medicare is the federal program: Part A for inpatient hospital care and Part B for doctor and outpatient services. Medicare Advantage, also called Part C, is a plan sold by a private company that Medicare pays to cover you. The plan must cover the services Original Medicare covers, and it usually adds extras and its own rules.
Where the paths split
With Original Medicare you can generally see any provider in the United States who accepts Medicare. There is no plan network in the Advantage sense. You still pay the Part B premium, and Part A and Part B have deductibles and coinsurance. Many people add a separate Part D drug plan and, if they are eligible, a Medigap policy to cover some of those gaps. Medigap is designed to work with Original Medicare. It does not pair with a Medicare Advantage plan.
A Medicare Advantage plan usually has a network. Staying in that network keeps costs predictable. Going outside it can cost more, or the care may not be covered, except in emergencies. The plan often includes drug coverage, so you do not buy a separate Part D plan. It also has a yearly limit on what you pay for covered Part A and Part B services. Original Medicare by itself does not have that kind of out-of-pocket cap.
Enrollment is on a calendar
The Annual Enrollment Period runs from October 15 through December 7. Coverage chosen then starts January 1. There is also a Medicare Advantage Open Enrollment Period from January 1 through March 31, when someone already in an Advantage plan can switch Advantage plans or return to Original Medicare. Special enrollment periods exist for moves, loss of other coverage, and other life events. Those windows are easy to miss if you only look at advertising.
What to read before you enroll
Ask for the plan’s Summary of Benefits and its provider directory, and check whether your doctors and hospital are in network for the coming year. Directories go stale. Call the office and ask if they will be in that specific plan, not merely “accept Medicare.” Look at the drug formulary if you take ongoing prescriptions. A plan with a low premium can still be expensive if your medicines sit on a high tier.
Cover Desk is not Medicare and does not enroll people in plans. Confirm rules in the Medicare & You handbook and on Medicare.gov, or with a State Health Insurance Assistance Program counselor.
