What This Code Means
O98.419 is the ICD-10-CM diagnosis code for viral hepatitis complicating pregnancy, unspecified trimester. Viral hepatitis complicating pregnancy when the specific trimester is not documented or known. O98.419 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).
O98.419 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.
Use only when trimester cannot be determined from available documentation.
