The ICD-10-CM codes and guidelines for the 2025 fiscal year (FY) have been released. The new codes will become effective on Oct. 1, 2024.
The ICD-10-CM guidelines have minor updates, and include the following:
The FY 2025 diagnosis code release resulted in a total of 74,260 codes. There are 252 additions, 36 deletions, and 13 revisions. The new codes include the following:
The Table of Drugs and Chemicals has been updated to include immune checkpoint inhibitors. This chapter also includes dehiscence of gastrointestinal tract, internal operation wound, and deep operation wound.
The Z codes include progesterone receptor status as well as expanded personal history of colonic polyps, which includes type. This chapter includes receptor status of other hormones and sepsis aftercare. The Social Determinants of Health (SDoH) section has been expanded to include insufficient social insurance and welfare support.
I am excited to see the expansion of the obesity codes, to include the obesity classes, which are frequently documented in medical records. The expansion of diabetes to include pre-diabetes Type 1 is interesting. This update also confirms that the SDoH are here to stay, and this data will continue to be important to capture. The biggest guideline change is the addition of guidelines for pre-symptomatic, Type 1 diabetes mellitus.
This code and guideline update will be further discussed during the ICD10monitor August webinars.
