The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes have been implemented to identify diagnoses with dates of service, or dates of discharge for inpatients, that occur on or after October 1, 2015. The updates for the Fiscal Year (FY) 2017 will represent the first code update since the implementation of ICD-10-CM in the US. As this coding system had been in a freeze for several years, there are a significant number of revisions. 2016 ICD-10-CM had 69,823 codes, with 71,486 codes in 2017 ICD-10-CM. This reflects 1,974 additions, 311 deletions, and 425 revisions.
