2023 ICD-10-PCS
2022 ICD-10-CM (CMS)
On October 1, 2015, the ICD-9 code sets used to report medical diagnoses and inpatient procedures were replaced by ICD-10 code sets. The transition to ICD-10 is required for everyone covered by the Health Insurance Portability Accountability Act (HIPAA). Please note, the change to ICD-10 does not affect CPT coding for outpatient procedures and physician services.

2021 ICD-10-CM (CMS)
The 2021 ICD-10-CM files below contain information on the ICD-10-CM updates for FY 2021. These 2021 ICD-10-CM codes are to be used for discharges occurring from October 1, 2020 through September 30, 2021 and for patient encounters occurring from October 1, 2020 through September 30, 2021.
Note: There is no FY 2021 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.
