Updated: Feb 10

Highly anticipated, the Centers for Medicare & Medicaid Services (CMS) released the ICD-10-CM code descriptions, tables and index, and addendum for fiscal year 2022. Although still pending are the 2022 Official Guidelines for Coding and Reporting, which were not included in the package of new codes. This update brings 159 additions, 25 deletions, and 27 revisions. ICD-10-CM 2022 goes into effect Oct. 1, 2021.

Below are highlights from the 43-page ICD-10-CM Tabular List of Diseases and Injuries 2022 Addenda. We’ll focus mostly on codes, so be sure to check for note and instruction updates in the official code set as you dig deeper into the changes that affect you.
