What This Code Means
O30.893 is the ICD-10-CM diagnosis code for other specified multiple gestation, unable to determine number of placenta and number of amniotic sacs, third trimester. A pregnancy with multiple babies (twins, triplets, etc.) in the third trimester where the number of placentas and amniotic sacs cannot be determined from available information. O30.893 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering maternal care related to the fetus and amniotic cavity and possible delivery problems (o30-o48).
O30.893 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 this code only when placental and amniotic sac configuration cannot be established despite clinical evaluation.
