Carrier (Health Care) Law and Legal Definition

A carrier is an entity or a private company that has a contract with center for medicare and medicated services (CMS) to determine whether medicare payments for part B benefits are payable on a charge basis, to pay one's physician and most other medicare part B bills and to perform other related functions. A medicare carrier will consider each physician's specialty and the patient's diagnosis to determine whether the medicare's definition of concurrent care is fulfilled. A medicare carrier will also determine whether a patient's condition requires the services of more than one attending physician.
