Medicare HOS Data Users Guides

Detailed documentation regarding file construction and contents has been assembled for all data sets distributed by this program. In addition to the Public Use Data Files (PUFs) available for download on this site, several unique data files have been distributed to participating Medicare Advantage Organizations (MAOs). These Data Users Guides (DUGs) have been assembled to facilitate the use of the HOS data files produced by the Medicare HOS Program.
