About coding contact with covid-19
The ICD-10-CM code for contact with covid-19 is Z20.822 (Contact with and (suspected) exposure to COVID-19).
Within Z20.82 (contact with and (suspected) exposure to other viral communicable diseases), Z20.822 is specifically for contact with and (suspected) exposure to COVID-19. Related codes cover varicella (Z20.820), Zika virus (Z20.821) and other viral communicable diseases (Z20.828).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 795 (Normal Newborn, relative weight 0.2022) and DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period) and MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
