ICD-10 Coding Resources
List of Valid ICD-10-CM Codes
CMS has posted a complete list of the 2016 ICD-10-CM valid codes and code titles in the 2016 Code Descriptions in Tabular Order ZIP file on the 2016 ICD-10-CM and GEMs web page. See the file named "icd10cm_codes_2016.txt" in the ZIP file for the list.
This file will be useful for physician offices and other providers who want to check to make sure that they are reporting all characters in a valid ICD-10-CM code. The codes are listed in tabular order (the order found in the ICD-10-CM code book). This list should assist providers who are unsure if additional characters are needed, such as the addition of a 7th character in order to arrive at a valid code.
A similar list of the 2016 ICD-10-PCS valid codes and code titles is available in the 2016 PCS Long and Abbreviated Titles ZIP file on the 2016 ICD-10 PCS and GEMs web page. See the file named "icd10pcs_codes_2016.txt" in the ZIP file for the list.
