Medicare Administrative Contractors
Payments to providers for hospital and medical services rendered to Medicare beneficiaries are handled by private insurance companies under contract with the federal government. Medicare Contracting Reform (or section 911 of the Medicare Prescription Drug, Improvement, and Modernization Act of 2003) mandated the Secretary for Health & Human Services replace the previous contracting authority to administer the Medicare Part A and Part B FFS programs, contained under Sections 1816 and 1842 of the Social Security Act, with the new Medicare Administrative Contactor authority. MACs, as these companies are now known, process claims for services covered under the Medicare Part A (Hospital) and Medicare Part B (Medical) programs.
MACs, under the Part A program, process claims submitted by facilities including (but not limited to) hospitals, skilled nursing facilities, home health associations, hospices, outpatient rehabilitation facilities and Community Mental Health Centers. Inpatient treatment in these facilities is covered under the Part A program and outpatient treatment in these facilities is covered under the Medicare Part B program. However, both types of treatment are billed to Part A program when the service is rendered in a facility setting.
Providers may often hear terminology that outpatient treatment at certain facility types is known as covered under “Part B of A.” This phrase is used when a Part B service is rendered in a facility setting, such as a hospital emergency room visit. Since this Part B service is rendered in a facility, it is billed to the Part A program.
MACs, under the Part B program, process claims submitted by physicians, freestanding laboratories and X-ray facilities, vendors and suppliers.
