What This Code Means
O00.209 is the ICD-10-CM diagnosis code for unspecified ovarian pregnancy without intrauterine pregnancy. A pregnancy that develops in an ovary instead of the uterus, but the specific ovary (left or right) is not specified, with no pregnancy in the uterus. O00.209 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering pregnancy with abortive outcome (o00-o08).
O00.209 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 only when laterality cannot be determined from documentation.
