Final answer:
Medicare Part B is the service plan that provides outpatient insurance, covering costs like physician services and medical tests for people over sixty-five and certain others with disabilities.
Step-by-step explanation:
The Medicare service plan that provides outpatient insurance is known as Part B. This plan is designed to cover health-care costs that are not associated with hospital stays. These can include physician services, various medical tests, and visits to outpatients. The individuals who opt for Part B coverage are required to pay a monthly fee, meet deductible charges, and make copayments for their services. The government subsidizes approximately 75% of the overall costs for this plan. Medicare, which includes Part B, primarily offers insurance to individuals over sixty-five years old as well as to some younger people with disabilities.
