What This Code Means
O34.80 is the ICD-10-CM diagnosis code for maternal care for other abnormalities of pelvic organs, unspecified trimester. Medical care provided during pregnancy for a pregnant woman who has other abnormal structures or conditions of the pelvic organs, when the specific trimester is not documented. O34.80 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).
O34.80 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 is a catch-all code for pelvic organ abnormalities not specified elsewhere; use only when trimester is unknown.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for O34.80 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
