Which component of Medicare is referred to as medical insurance?

Medicare Part B is referred to as medical insurance because it primarily covers outpatient care, physician services, preventive services, and some home health care. Unlike Part A, which focuses on hospital insurance and inpatient care, Part B is designed to provide coverage for services that are essential for maintaining and improving health outside of a hospital setting. This includes doctor visits, outpatient therapies, and necessary medical supplies. Part B plays a crucial role in ensuring that beneficiaries have access to necessary health care services that can prevent the need for more extensive hospital care later on. Therefore, it's appropriate to identify Part B as the component of Medicare that specifically addresses medical insurance needs.
