Official Description

Cerclage of cervix, during pregnancy; vaginal

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 59320 refers to the cerclage of the cervix during pregnancy, a surgical intervention aimed at addressing an incompetent cervix. An incompetent cervix is a condition where the cervix begins to open prematurely, which can lead to complications such as miscarriage or preterm labor. This procedure is particularly indicated for women with a history of second-trimester miscarriages, those who have undergone cervical surgeries such as loop electrical excision procedures or cone biopsies, or those who have experienced other forms of cervical injury. The primary goal of cervical cerclage is to provide support to the cervix, preventing it from dilating too early and thereby reducing the risk of premature labor and delivery. Typically, this procedure is performed between 12 to 14 weeks of gestation; however, it can also be conducted as an emergency measure later in pregnancy if there are signs of cervical opening. The cerclage is placed using a vaginal approach, where the physician may employ techniques such as the McDonald-type cerclage, which involves weaving a purse-string suture around the cervix, or the Shirodkar-type procedure, which involves tunneling the suture subcutaneously around the cervix. Both methods aim to secure the cervix and maintain its closure throughout the pregnancy.

1. Indications

The cerclage of the cervix during pregnancy is indicated for several specific conditions and circumstances that may compromise the integrity of the cervix. These indications include:

  • Incompetent Cervix - A condition where the cervix is unable to remain closed during pregnancy, leading to a risk of premature labor.
  • History of Second Trimester Miscarriage - Previous miscarriages occurring in the second trimester may suggest a need for cervical support to prevent recurrence.
  • Previous Cervical Procedures - Women who have undergone loop electrical excision procedures or cone biopsies of the cervix may have weakened cervical tissue, necessitating cerclage.
  • Other Cervical Injuries - Any injury to the cervix that could compromise its ability to remain closed during pregnancy may warrant the placement of a cerclage.

2. Procedure

The procedure for cervical cerclage involves several key steps to ensure the effective placement of the suture around the cervix. The following procedural steps are typically followed:

  • Step 1: Patient Preparation - The patient is positioned appropriately, usually in a lithotomy position, to allow access to the vaginal canal. Anesthesia may be administered as needed to ensure comfort during the procedure.
  • Step 2: Vaginal Examination - A thorough vaginal examination is conducted to assess the condition of the cervix and confirm the need for cerclage. This may include checking for any signs of cervical dilation or effacement.
  • Step 3: Suture Placement - The physician performs the cerclage using a vaginal approach. For a McDonald-type cerclage, a purse-string suture is woven in and out around the cervix and then tightened to secure it. Alternatively, for a Shirodkar-type procedure, the suture is tunneled subcutaneously around the cervix before being cinched together.
  • Step 4: Confirmation of Placement - After the suture is placed, the physician may perform a final examination to ensure that the cervix is adequately supported and that there are no complications from the procedure.
  • Step 5: Post-Procedure Monitoring - The patient is monitored for any immediate complications, and instructions are provided regarding activity restrictions and follow-up care.

3. Post-Procedure

After the cervical cerclage procedure, patients are typically advised to rest and avoid strenuous activities to minimize the risk of complications. Monitoring for any signs of infection, bleeding, or premature labor is crucial. Follow-up appointments are scheduled to assess the condition of the cervix and the effectiveness of the cerclage throughout the remainder of the pregnancy. Patients may also receive guidance on managing any discomfort and understanding the signs that would require immediate medical attention.
