New COVID-Related Diagnosis Codes Introduced & Effective January 1, 2021

January 5, 2021

In our April White Paper, we explained the coding guidelines for the application of the COVID-19 diagnosis code, U07.1, and described the CDC’s Interim Coding Guidance for clinical scenarios that do not result in COVID infection diagnoses.

The Centers for Disease Control and Prevention’s National Center for Health Statistics (CDC/NCHS) has recently announced additions to ICD-10-CM that will become effective January 1, 2021, for conditions resulting from COVID-19.  These newly created codes are intended to provide for better monitoring and trending of COVID-19 information through healthcare claims and will include:

•    Encounter for screening for COVID-19 (Z11.52)
•    Contact with and (suspected) exposure to COVID-19 (Z20.822)
•    Personal History of COVID-19 (Z86.16)
•    Multisystem inflammatory syndrome (MIS) (M35.81)
•    Other specified systemic involvement of connective tissue (M35.89)
•    Pneumonia due to coronavirus disease 2019 (J12.82)
