Medicare part b
DEFINITION: Original Medicare is made up of two parts: Medicare Part A (inpatient) and Medicare Part B (outpatient).
Medicare Part B or “medical insurance” covers medically necessary outpatient expenses, including physician and nursing fees, as well as a range of services (such as x-rays, diagnostic tests, some vaccinations and renal dialysis) and some equipment.
Find out how to enroll and what Medicare Part B costs (although most seniors receive Medicare Part A for free, Medicare Part B has a monthly premium, which can fluctuate from year to year. In most cases, the Part B premium is simply withdrawn from your Social Security check).
