About coding viral hepatitis contact
The ICD-10-CM code for viral hepatitis contact is Z20.5 (Contact with and (suspected) exposure to viral hepatitis).
Within Z20 (contact with and (suspected) exposure to communicable diseases), Z20.5 is specifically for contact with and (suspected) exposure to viral hepatitis. Related codes cover intestinal infectious diseases (Z20.0), tuberculosis (Z20.1), infections with a predominantly sexual mode of transmission (Z20.2), rabies (Z20.3), rubella (Z20.4), human immunodeficiency virus [HIV] (Z20.6), pediculosis, acariasis and other infestations (Z20.7), other communicable diseases (Z20.8) and 1 more.
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.
