Medical Code Data files are not software. There is no search application. Data Files are designed to be used in any database, spreadsheet or other application that accepts a text (.txt) file format. Data files contain a complete list of official, valid codes; short, medium and unabbreviated, full code descriptions; as well as additional content to provide all the information you need to keep your practice running efficiently and effectively. Each publisher provides their own version of the files and may not contain all of the descriptions. Please check before you purchase!
