CPT® Code 58340

Catheterization and introduction of saline or contrast material for saline infusion sonohysterography (SIS) or hysterosalpingography

The procedure described by CPT® Code 58340 involves the catheterization and introduction of saline or contrast material into the uterus for the purposes of saline infusion sonohysterography (SIS) or hysterosalpingography. In SIS, the physician begins by performing a baseline transvaginal ultrasound to assess the uterine cavity. Following this initial imaging, a speculum is inserted to allow access to the cervix, which is then cleansed to ensure a sterile environment. A small-diameter flexible catheter is carefully placed through the cervix and into the uterine cavity. After the catheter is positioned, the speculum is removed, and the transvaginal ultrasound probe is reinserted to visualize the uterus. Sterile saline or contrast media is then instilled through the catheter into the uterine cavity, expanding it adequately for detailed imaging. In the case of hysterosalpingography, the catheterization process is similar; however, after the speculum is removed, fluoroscopy is utilized to visualize the uterus and Fallopian tubes as the contrast media is introduced. This procedure is essential for evaluating uterine abnormalities and assessing the patency of the Fallopian tubes, providing critical information for further management of reproductive health issues.
