Standard Analytical Files
The Centers for Medicare and Medicaid Services (CMS) collects data from all hospitals, home health agencies, nursing homes, and hospices that provide services to Medicare beneficiaries on an ongoing basis through its fiscal intermediaries, and compiles the data for each calendar year.
