About the O09 Code Range
ICD-10 code range O09 is used for documenting the supervision of high risk pregnancies, which involves close monitoring of pregnancies complicated by various maternal history factors or social conditions. These codes specify the reason for high-risk pregnancy supervision and often differentiate by trimester to provide precise care documentation.
This range includes codes for pregnancies with a history of infertility (such as O09.00 for unspecified trimester), ectopic pregnancy, or other poor reproductive and obstetric histories like preterm labor (O09.219) or stillbirth. It also covers supervision based on characteristics such as grand multiparity (e.g., O09.40), advanced maternal age including elderly primigravida and multigravida statuses (O09.519 and O09.529), and very young maternal age (O09.619 and O09.629). Social factors influencing pregnancy risk, like poor home conditions or child abuse history (O09.70), as well as pregnancies from assisted reproductive technologies such as IVF (O09.819), are represented. Additionally, supervision codes address previous specific pregnancy complications such as molar pregnancy (O09.A) or in utero procedures (O09.82). This detailed categorization helps healthcare providers and coders accurately record the oversight needed for pregnancies with unique monitoring needs across different trimesters.
