Is O30.892 an HCC code?
No. O30.892 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
O30.892 is the ICD-10-CM diagnosis code for other specified multiple gestation, unable to determine number of placenta and number of amniotic sacs, second trimester. A multiple pregnancy where the number of placentas and amniotic sacs cannot be determined from available imaging or documentation, occurring in the second trimester (weeks 13-27). O30.892 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).
O30.892 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 reason for inability to determine chorionicity and amnionicity (e.g., poor visualization, early dating).
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O30.892 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the reason for inability to determine chorionicity and amnionicity (e.g., poor visualization, early dating)
- •Follow-up imaging may be needed to clarify the pregnancy configuration for risk stratification
