What This Code Means
O9A.419 is the ICD-10-CM diagnosis code for sexual abuse complicating pregnancy, unspecified trimester. A pregnant woman is experiencing sexual abuse, but the specific trimester when the abuse occurred is not documented or specified in the medical record. O9A.419 sits in the ICD-10-CM chapter for pregnancy, childbirth and the puerperium (o00-o9a), within the section covering other obstetric conditions, not elsewhere classified (o94-o9a).
O9A.419 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 code should be used only when trimester information is unavailable; attempt to obtain clarification from the provider.
