Q Can the code for obstetric transvaginal ultrasound be used any time during the patient’s pregnancy?
A Yes. The code 76817 (ultrasound, pregnant uterus, real time with image documentation, transvaginal) does not specify a gestational period, unlike the new and revised codes 76801–76810 (for fetal and maternal evaluation either prior to or later than 14 weeks, 0 days of gestation). Thus, 76817 can be used at any time.
