Medicare Policies
General Information
Medicare is a single-payer, national insurance program administered by the U.S. federal government for people age 65 or older, people under age 65 with certain disabilities, and people of all ages with end-stage renal disease.
Medicare has four parts: Part A is hospital/hospice insurance, Part B is medical insurance, Part C includes health plans branded as Medicare Advantage and Part D covers many prescription drugs. Providers working in hospital settings, including critical access hospitals and skilled nursing facilities, are considered Medicare Part A providers. Providers working in outpatient clinics and settings are considered Medicare Part B providers. The Medicare Provider-Supplier Enrollment webpage provides additional details on how to enroll as a Medicare provider or supplier.
The Centers for Medicare and Medicaid Services (CMS) establishes national coverage determinations (NCDs) for items and services furnished through Medicare.
CMS also awards geographic jurisdictions to private health care insurers called Medicare Administrative Contractors (MACs) to develop policies and process claims. The policies that MACs develop are called Local Coverage Determinations (LCDs) and these may vary from region to region. An LCD can never contradict an NCD, but it can expand on coverage policies for a particular region.
A/B MACs process Medicare Part A and Medicare Part B claims for a defined geographic area or “jurisdiction.” Part A and B providers are required to adhere to the LCD(s) that is in place for their particular jurisdiction.
