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.
Certain Infectious and Parasitic Diseases
For sepsis following a postprocedural wound (surgical site) infection, a code from T81.41 to T81.43,
Infection following a procedure, or a code from O86.00 to O86.03, Infection of obstetric surgical
wound, that identifies the site of the infection should be sequenced first.
Screening for COVID-19: For screening for COVID-19, including preoperative testing, assign code
Z11.52, Encounter for screening for COVID-19.
Neoplasms:
Familial adenomatous polyposis (FAP) D13.91
In the table of Neoplasms, D13.9 is revised to D13.99 for a handful of applicable body areas.
