Special Notes: 

  (1) The service area for HCPP - 1933 Cost organizations is the entire United States.
  CMS systems have not traditionally stored the 3300 plus rows of data to to define
  each and every state and county for this organization type. This file continues
  this tradition because to expand out these contracts would add close to 30,000
  rows of data. These specific contracts have information in the notes column. 

  (2) The data file contains more than 65,536 rows of data. This means that Microsoft
  Excel will not be able to import all of the data for viewing. All of the data 
  can be viewed in Microsoft Access or in a statistical package, such as SAS. 

  (3) Pilot contracts are excluded from this file.
