What This Code Means

O34.11 is the ICD-10-CM diagnosis code for maternal care for benign tumor of corpus uteri, first trimester. A pregnant woman in her first trimester receives care for a non-cancerous tumor in the main body of the uterus. O34.11 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).

O34.11 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.
