To make things easy there are only 3 Medicare Supplement Plans that most people buy. Let's take a look at those.
Medicare Part A will cover stays within a facility such as inpatient hospitals, skilled nursing and portions of home health care. Part A is typically free of charge.
Medicare Part B covers all of your outpatient medical. This can include preventative care, surgeries and lab work. Part B will help pay for services that are medically necessary to diagnose or treat a medical condition and performed on an outpatient basis.
Medicare Part D is also commonly known as prescription drug coverage. Part D is available as a Part C or as a Stand-Alone Option (PDP). Like Part C, these Part D plans are offered by private insurance companies.
Since the only thing that varies from company to company is price it makes sense to pick the cheapest of the plan type you wish to have when you first go on to Medicare because you get to select a plan without any medical underwriting. If you wish to change plans after that, you will have to health qualify to make a change. Health qualifications vary from carrier to carrier.
