Is O30.193 an HCC code?
No. O30.193 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
O30.193 is the ICD-10-CM diagnosis code for triplet pregnancy, unable to determine number of placenta and number of amniotic sacs, third trimester. A pregnancy with three fetuses where the exact arrangement of placentas and fluid sacs cannot be determined, occurring in the third trimester (last three months of pregnancy). O30.193 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).
O30.193 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 is used when ultrasound or other imaging cannot clearly identify the placental and amniotic sac configuration in triplet pregnancies.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O30.193 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This code is used when ultrasound or other imaging cannot clearly identify the placental and amniotic sac configuration in triplet pregnancies
- •Always specify the trimester; use O30.199 only when the trimester is truly unknown or not documented
