Is O30.201 an HCC code?
No. O30.201 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
O30.201 is the ICD-10-CM diagnosis code for quadruplet pregnancy, unspecified number of placenta and unspecified number of amniotic sacs, first trimester. A pregnancy with four fetuses where the number of placentas and fluid sacs is not specified, occurring in the first trimester (first three months of pregnancy). O30.201 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).
O30.201 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 when placental and amniotic sac details are not documented or cannot be determined for quadruplet pregnancies.

Coding Tips
- •Use this code when placental and amniotic sac details are not documented or cannot be determined for quadruplet pregnancies
- •If more specific information about monochorionic or dichorionic status becomes available, update to a more specific code (O30.21x series)
