Obstetrical Ultrasound Imaging Guidelines

Obstetrical Ultrasound Imaging Guidelines cover obstetric ultrasound examinations (e.g., fetal anatomy/dating/viability scans, cervical length, IUD localization, and targeted/diagnostic ultrasounds) for pregnant individuals and related conditions including infertility/ART pregnancies, recurrent pregnancy loss, vaginal bleeding, suspected ectopic pregnancy, hydatidiform mole, and fetal aneuploidy/anomaly screening. Major requirements/limitations include an initial clinical evaluation prior to imaging, use of obstetrical CPT codes only with a confirmed pregnancy, optimal timing of a routine single fetal anatomy scan at 18–22 weeks (earlier scans are for specific indications), coding restrictions (non‑obstetrical pelvic ultrasound codes are inappropriate with confirmed pregnancy), and physician review for atypical presentations not addressed by the criteria.
