For most people choosing to enroll in Original Medicare, when they sign up for Part A (Hospital Insurance), they will likely also choose Part B (Medical Insurance). Part A is free for more than 90% of the people enrolled. Your monthly premium for Part B however is income-based so will vary based on your personal circumstances.
Part A covers most hospital-related services, such as in-patient hospital stays, care in a skilled nursing facility, hospice care, and some home-health care. In some cases, you might qualify for free Part A, depending on Social Security benefits and other potential factors. Part B covers most medical services, such as doctors’ services, out-patient care, medical supplies, and preventive services.
There are many factors that can affect your out-of-pocket expenses under Original Medicare, such as whether your doctor or healthcare provider accepts Medicare, the type of healthcare treatment you need, and if you have other health insurance or supplemental coverage (Medigap).
