ICD UPDATES


Practicefirst would like to notify its clients of the following ICD updates from CMS.


ICD-10 MS-DRGs Version 39.1 Effective April 1, 2022


In response to the ongoing national emergency concerning COVID-19, the Centers for Disease

Control and Prevention’s (CDC) National Center for Health Statistics (NCHS) is implementing 3

new diagnosis codes, Z28.310, Z28.311 and Z28.39, into the International Classification of

Diseases, Tenth Revision, Clinical Modification (ICD-10-CM), for reporting COVID-19 vaccination

status effective April 1, 2022.


The ICD-10 MS-DRG Grouper assigns each case into an MS-DRG based on the reported

diagnosis and procedure codes and demographic information (age, sex, and discharge status).


The ICD-10 MCE Version 39.1 uses edits for the ICD-10 codes reported to validate correct

coding on claims for discharges on or after April 1, 2022.


The ICD-10 MS-DRG Grouper software package to accommodate these new codes, Version

39.1, is effective for discharges on or after April 1, 2022.


Assignment of new ICD-10-CM diagnosis codes Z28.310, Z28.311 and Z28.39, is as follows:


Diagnosis Code Description

Z28.310 Unvaccinated for COVID-19

Z28.311 Partially vaccinated for COVID-19

Z28.39 Other underimmunization status

Definitions of Medicare Code Edits V39.1 manual will be available at
