What This Code Means
P02.78 is the ICD-10-CM diagnosis code for newborn affected by other conditions from chorioamnionitis. A newborn is affected by inflammation of the amniotic membranes and fluid surrounding the fetus, which can cause infection and complications for the baby. P02.78 sits in the ICD-10-CM chapter for certain conditions originating in the perinatal period (p00-p96), within the section covering newborn affected by maternal factors and by complications of pregnancy, labor, and delivery (p00-p04).
P02.78 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.
Document the maternal fever, elevated white blood cell count, or other signs of chorioamnionitis.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for P02.78 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
