Updated 2021 ICD-10-CM Coding Guidelines Now Available

Updated 2021 ICD-10-CM Coding Guidelines Now Available

 

Updates to the ICD-10-CM and ICD-10-PCS codes for January 1, 2021 include 27 new codes: 21 PCS and six CM codes. For the diagnosis codes, changes to the ICD-10-CM Official Guidelines were released on December 16, 2020, to reflect these six new codes.

These updates include substitution of the new code for pneumonia due to COVID-19, J12.82; contact with and (suspected) exposure to COVID-19, Z20.822; and personal history of COVID-19, Z86.16. There is a new section in the guidelines pertaining to multisystem inflammatory syndrome, M35.81. Code M35.89 for other specified systemic involvement of connective tissue is also available but not included in the guidelines.

Although a new code for COVID-19 screening, Z11.52, was released, the guidelines specify that this code is not appropriate during the pandemic and should not be reported. Instead, encounters for COVID-19 testing, including preoperative testing, are coded as exposure to COVID-19. The guidelines state that this advice will be updated as the status of the pandemic changes and the reporting of the screening code is applicable.

The addenda for the tabular list and index related to these code changes for January 2021 can be downloaded from the CDC website (2020).

For more information, see the CDC announcement of the ICD-10-CM codes effective on January 1, 2021 (CDC, 2020).
