EDITOR’S NOTE: The Centers for Disease Control and Prevention (CDC) which administers the diagnosis codes released the 2017 ICD-10-CM codes on June 24, 2016. This information can be found at https://www.cms.gov/Medicare/Coding/ICD10/2017-ICD-10-CM-and-GEMs.html 

Since the release of the 2017 ICD-10-PCS codes, the healthcare vendor community has been waiting with bated breath for the 2017 ICD-10-CM codes. Now they’re here. 

Those codes were just released on June 24, 2016 with the Index and Tabular files. There are 1,974 additions, 311 deletions, and 425 revisions. The resulting total for diagnosis codes is 71,486.

The addenda for the Index (90 pages), Table of Drugs and Chemicals (2 pages), Neoplasm Table (11 pages), External Cause Index (9 pages), and Tabular (160 pages) are included in this release. Two additional files include the Code Descriptor in Tabular Order file and Duplicate Code file.   

The addenda provide information regarding the changes for the code set. The Code Descriptor in Tabular Order provides the code descriptor at each level of the code set. One important file that is missing from the update is the 2017 ICD-10-CM Official Coding and Reporting Guidelines. That information is still pending as well as the General Equivalence Mappings (GEMs).

The last important piece to the updates will be the Inpatient Prospective Payment System (IPPS) Final Rule FY2017 to see what is new in the MS-DRGs as well as value based purchasing.
