Find out Which O99.- Code Fits This Obstetrical Trauma Case
Question: A patient came in for a 36-week growth ultrasound (US) due to previous obstetrical trauma. The provider ordered the US to evaluate if the fetus could be delivered vaginally because of the previous trauma. What diagnosis code can I use for the US? Ohio Subscriber Answer: Your best option would be a code in the O99.89- (Other specified diseases and conditions complicating pregnancy, childbirth and the puerperium) subcategory. The two code options that stand out in this situation are O99.891 (Other specified diseases and conditions complicating pregnancy) and O99.892 (Other specified diseases and conditions complicating childbirth). The patient came in for a growth US while 36 weeks pregnant. Since they didn’t deliver during the visit, you will assign O99.891 to indicate the visit was for a condition affecting the pregnancy. However, if the patient did deliver the baby, then you’d use O99.892 on the claim. Mike Shaughnessy, BA, CPC, Production Editor, AAPC
