The ICD-10-CM code set is getting an update for the fiscal year 2024. This update includes the addition of 395 new codes, the deletion of 25 existing codes, and revisions to 22 codes (with nine of them being changes to the short title only).
Furthermore, there are 131 new headers and four revised headers. While not every section from A to Z is affected, the changes are extensive and will be in effect starting from October 1, 2023.
