2020 ICD-10-CM
The 2020 ICD-10-CM files below contain information on the ICD-10-CM updates for FY 2020. These 2020 ICD-10-CM codes are to be used for discharges occurring from October 1, 2019 through September 30, 2020 and for patient encounters occurring from October 1, 2019 through September 30, 2020.
Note: There is no FY 2020 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
