CPT® Code 58345

Transcervical introduction of fallopian tube catheter for diagnosis and/or re-establishing patency (any method), with or without hysterosalpingography

The CPT® Code 58345 refers to the transcervical introduction of a fallopian tube catheter, a procedure utilized for both diagnostic purposes and the re-establishment of patency in the fallopian tubes. This procedure can be performed using various methods and may or may not include hysterosalpingography, which is an imaging technique used to visualize the inside of the uterus and fallopian tubes. During the procedure, a physician typically begins with a baseline transvaginal ultrasound to assess the reproductive anatomy. Following this, a speculum is inserted into the vagina to allow access to the cervix, which is then cleansed to minimize the risk of infection. A small-diameter flexible catheter is carefully introduced through the cervix into the uterine cavity and advanced to the proximal tubal ostium, the opening of the fallopian tube. Contrast media is subsequently instilled into the fallopian tube to evaluate its patency, meaning whether it is open or blocked. If an obstruction is detected in the proximal tube, the physician may attempt to recanalize it using a guidewire, potentially in conjunction with a coaxial catheter. This process may be repeated on the opposite side if necessary. Additionally, if both the uterus and fallopian tubes are to be evaluated, contrast is instilled into the uterine cavity, enhancing the diagnostic capability of the procedure.
