Original Medicare is the federal health insurance program made up of Part A and Part B. Most people become eligible at 65, though some younger people qualify because of disability or certain health conditions. If you are enrolled in Original Medicare, Part A generally helps pay for inpatient hospital care, skilled nursing facility care following a qualifying hospital stay, hospice, and limited home health services.
Many beneficiaries pay no monthly Part A premium because of their work history, but deductibles and daily cost-sharing can still apply. At a glance: Part A generally helps with hospital-related care, while Part B helps cover doctor visits, outpatient care, preventive services, and medical equipment.
Part B covers many of the everyday medical services people rely on outside a hospital: doctor visits, outpatient surgery, lab work, imaging, preventive care, durable medical equipment, and certain home health care. Part B has a monthly premium, an annual deductible, and typically leaves you responsible for 20% coinsurance after the deductible is met.
There is no annual out-of-pocket maximum under Original Medicare alone, so those remaining costs deserve careful attention. You can see any provider nationwide who accepts Medicare, without needing referrals in most cases.
Still, Original Medicare does not ordinarily include routine dental, vision, hearing, or most prescription drug coverage. Those gaps are why many people compare a standalone Part D drug plan, Medicare Supplement insurance, or a Medicare Advantage plan before deciding how they want their coverage to work.
