Final answer:
Medicare Part B covers physician expenses, including doctors' services, medical tests, and outpatient visits. It is a part of the broader Medicare program created to provide healthcare to those over 65 and certain younger individuals with disabilities.
Step-by-step explanation:
Medicare Part B is an optional insurance program that primarily covers physician expenses, including services provided by doctors, medical tests, and outpatient visits. It does not cover long-term care, hospitalization, or disability, which are associated with other parts of Medicare. Participants of Part B pay a monthly premium, have a deductible to meet, and are responsible for copayments for these services. The government subsidizes around three-fourths of the overall costs of this program.
As an important component of Medicare, established in 1965, Part B plays a vital role in supporting the healthcare needs of eligible individuals, typically those who are over the age of 65 or certain younger people with disabilities.
