what is medicare part a and part b mean?
What Is Medicare Part B? Medicare Part B (medical insurance) is part of Original Medicare and covers services and supplies that are medically necessary to treat your health condition. This can include outpatient care, preventive services, ambulance services, and durable medical equipment.
Medicare Part A is hospital insurance. Just about everyone age 65 and over is eligible for Medicare Part A, though some have to pay a monthly premium. But being eligible doesn't mean that Part A covers all hospital costs, and even after Part A does pay, participants are typically left with hefty out-of-pocket costs.
