CPT® Code 74742

1. Indications

The transcervical catheterization of the fallopian tube, as described by CPT® Code 74742, is indicated for the evaluation of female infertility, particularly when assessing the patency of the fallopian tubes. This procedure is performed in cases where there is a suspicion of tubal obstruction, which can impede the passage of sperm to the egg or the transport of the fertilized egg to the uterus. The following conditions may warrant this procedure:

• Infertility Evaluation Assessment of female infertility when there is a need to determine if the fallopian tubes are open.
• Suspected Tubal Obstruction Investigation of potential blockages in the fallopian tubes that may affect fertility.
• Prior Pelvic Surgery Evaluation of tubal patency in patients with a history of pelvic surgery that may have impacted the fallopian tubes.

2. Procedure

The procedure of transcervical catheterization of the fallopian tube involves several key steps, each critical for ensuring accurate results and patient safety. The following outlines the procedural steps:

• Step 1: Patient Positioning The patient is positioned under a fluoroscopy device to allow for real-time imaging during the procedure. This positioning is essential for guiding the catheter accurately into the fallopian tubes.
• Step 2: Catheter Insertion A catheter is inserted through the cervix into the uterus. This step requires careful technique to ensure that the catheter is placed correctly without causing trauma to the surrounding tissues.
• Step 3: Advancement into the Tubal Ostium The catheter is then advanced into the tubal ostium, which is the opening of the fallopian tube. This advancement is monitored under fluoroscopy to confirm proper placement.
• Step 4: Contrast Instillation Once the catheter is in place, contrast material is instilled into the fallopian tubes. The physician observes the fluoroscopic images to assess the flow of contrast and identify any obstructions or abnormalities within the tubes.
• Step 5: Recanalization (if necessary) If an obstruction is detected during the imaging, the physician may supervise a separately reportable recanalization procedure to attempt to clear the blockage.
• Step 6: Catheterization of the Opposite Side If indicated, the catheterization may be repeated on the opposite fallopian tube to ensure a comprehensive evaluation of both tubes.
• Step 7: Catheter Removal and Interpretation After the procedure is completed, the catheter is removed. The physician then provides a written interpretation of the findings, which is essential for guiding further treatment options.

3. Post-Procedure

Following the transcervical catheterization of the fallopian tube, patients may experience some mild discomfort or cramping, which is typically transient. It is important for the physician to provide post-procedure care instructions, including monitoring for any unusual symptoms such as severe pain or bleeding. Patients are usually advised to avoid strenuous activities for a short period following the procedure. The written interpretation of the findings should be reviewed with the patient to discuss the results and any necessary follow-up actions or treatments based on the findings of the procedure.
