2023 ICD-10-CM

April 1, 2023 UPDATE

In an effort to better enable the collection of health-related social needs (HRSNs), defined as individual-level, adverse social conditions that negatively impact a person’s health or healthcare, are significant risk factors associated with worse health outcomes as well as increased healthcare utilization, the Centers for Disease Control and Prevention’s (CDC) National Center for Health Statistics (NCHS) is implementing 42 new diagnosis codes into the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), for reporting effective April 1, 2023.

The files in the Downloads section below contain information on the ICD-10-CM updates effective with discharges on and after April 1, 2023.

The 2023 ICD-10-CM files below contain information on the ICD-10-CM updates for FY 2023. These 2023 ICD-10-CM codes are to be used for discharges occurring from October 1, 2022 through September 30, 2023 and for patient encounters occurring from October 1, 2022 through September 30, 2023.

Note:

There is no FY 2023 GEMs file. As stated in the FY 2016 IPPS/LTCH PPS final rule (80 FR 49388), the GEMs have been updated on an annual basis as part of the ICD-10 Coordination and Maintenance Committee meetings process and will continue to be updated for approximately 3 years after ICD-10 is implemented.


We made the GEMs files available for FY 2016, FY 2017 and FY 2018.

An announcement was also made at the September 2017 ICD-10 Coordination and Maintenance Committee meeting that FY 2018 would be the last GEMs file update.
