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).

Here is a brief synopsis of additions and changes throughout the code set.  Conditions that were added throughout the code set is postoperative seroma which had been discussed at Coordination and Maintenance Meeting in March 2016. 

There is only one addition to Chapter 1 (Infectious and Parasitic Diseases) which is A92.5.    This code has been assigned by the World Health Organization (WHO) for the Zika Virus.   

There are numerous code title revisions throughout Chapter 2 (Neoplasms) with five new codes.    

There are five new codes in Chapter 3 (Diseases of Blood and Blood Forming Organs and Certain Disorders Involving the Immune Mechanism).   

The revisions to Chapter 4 (Endocrine, Metabolic, and Nutritional Diseases) include further specificity of diabetic retinopathy (proliferative vs. non-proliferative and severity of mild, moderate, or severe) and the ability to capture that macular edema has resolved after treatment with laterality.

There are many long-awaited updates in this release of ICD-10-CM. There are still many that have been discussed during the Coordination and Maintenance Committee meetings that have not been addressed such as the myocardial infarction, type II. It is important to continue to monitor these meetings for future updates.    

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.
