Part B is the part of Medicare that covers outpatient care. Outpatient services include doctor’s visits, preventive care, durable medical equipment (DME), laboratory tests, x-rays, and ambulance services.
Whether or not someone who is eligible for Medicare should take Part B depends on how the person receives his or her insurance benefits. Medicare can be either primary or secondary to other insurance. If someone does not enroll into Medicare Part B when they should, even if they believe they are covered, they could pay penalties or have no insurance coverage at all.
