Database XML、CSV 或数据库格式的 ICD9 代码列表

删除RTF后，解析文件并将其转换为CSV并不是太难.我得到的包含所有2009年疾病和程序ICD-9代码的解析文件如下:http://www.jacotay.com/files/Disease_and_ProcedureCodes_Parsed.zip 我编写的解析器在这里:http://www.jacotay.com/files/RTFApp.zip 这基本上是一个两步的过程-从CDC FTP站点获取文件，从中删除RTF，然后 Select 无RTF的文件并将其解析为CSV文件. 这里的代码非常粗糙，因为我只需要输出一次结果.

以下是解析应用程序的代码，以防外部链接关闭(后端到一个允许您 Select 文件名并单击按钮的表单)
