NOTICE: PLEASE RETAIN PRIOR VERSIONS OF THE IOCE DATA FILES: The data files for each issue of the IOCE represent the updated data files for that release. Consequently, if there are no changes to a particular file for a particular update, that file is usually not included on the data CD. APC, HCPCS and CCI files will always be present because those files are updated every quarter.


Files are in Microsoft Word and Excel.
