What This Code Means
O98.42 is the ICD-10-CM diagnosis code for viral hepatitis complicating childbirth. Viral hepatitis that occurs during labor and delivery and may complicate the childbirth process or affect the newborn. O98.42 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering other obstetric conditions, not elsewhere classified (o94-o9a).
O98.42 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
This code applies to viral hepatitis present during the actual labor and delivery period.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O98.42 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
