Official Description

Placement of needles or catheters into pelvic organs and/or genitalia (except prostate) for subsequent interstitial radioelement application

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 55920 refers to the procedure involving the placement of needles or catheters into pelvic organs and/or genitalia, specifically excluding the prostate, for the purpose of subsequent interstitial radioelement application. This procedure is a critical step in the treatment of certain malignancies, as it facilitates the delivery of brachytherapy, a form of radiation therapy where radioactive sources are placed directly within or near the tumor. The placement of these needles or catheters is essential for ensuring that the radiation is accurately targeted to the tumor while minimizing exposure to surrounding healthy tissues. The procedure is tailored to the specific anatomical considerations of the patient, taking into account the location of the malignant neoplasm and the differences in male and female anatomy. During the procedure, various tools and techniques are employed, including the use of a radiopaque urinary tract catheter to assist in visualizing the urethral meatus, and the assessment of tumor volume and its relationship to adjacent normal structures. A template device may also be utilized to ensure precise orientation of the brachytherapy needles or catheters, which are then sutured into place. The overall goal of this procedure is to prepare the patient for the subsequent application of radioactive elements, which is reported separately under a different code.

1. Indications

The procedure coded as CPT® 55920 is indicated for the placement of needles or catheters into pelvic organs and/or genitalia, excluding the prostate, for the purpose of subsequent interstitial radioelement application. This procedure is typically performed in patients diagnosed with malignant neoplasms located in the pelvic region, where targeted radiation therapy is necessary to treat the cancer effectively.

  • Malignant Neoplasms The primary indication for this procedure is the presence of malignant tumors in the pelvic organs or genitalia, necessitating localized treatment through brachytherapy.
  • Assessment of Tumor Volume The procedure is also indicated when there is a need to assess the volume of the tumor to determine the appropriate treatment plan.
  • Evaluation of Tumor Relationship to Normal Structures It is indicated when evaluating the relationship of the tumor to surrounding normal anatomical structures to ensure precise placement of the brachytherapy devices.

2. Procedure

The procedure involves several critical steps to ensure the accurate placement of needles or catheters. Initially, a radiopaque urinary tract catheter may be inserted into the bladder to mark the urethral meatus, which aids in visualizing the anatomy during the procedure. Following this, the tumor volume is assessed, and the relationship of the tumor to adjacent normal structures is carefully evaluated. Based on these assessments, a template device may be selected and prepared to orient the brachytherapy needles or catheters accurately. This template is then sutured into place to maintain its position during the procedure.

  • Step 1: Insertion of Catheter A radiopaque urinary tract catheter is inserted into the bladder to assist in visualizing the urethral meatus, which is crucial for accurate placement of the brachytherapy devices.
  • Step 2: Tumor Assessment The volume of the tumor is assessed, and its relationship to surrounding normal structures is evaluated to inform the placement strategy.
  • Step 3: Template Preparation A template device is selected and prepared to orient the brachytherapy needles or catheters, ensuring precise placement, and is sutured into position.
  • Step 4: Selection of Devices Needles, catheters, and other necessary devices, such as guide probes, guidewires, or a vaginal cylinder in females, are selected and prepared for placement based on the tumor's extent and anatomical distribution.
  • Step 5: Skin Puncture and Insertion The skin over the first insertion site is punctured, and the brachytherapy needle or catheter is advanced to the selected site, ensuring accurate placement.
  • Step 6: Digital Rectal Palpation Digital rectal palpation may be utilized to guide the placement of needles and catheters in the posterior aspect of the genital region, ensuring proper positioning.
  • Step 7: Completion of Placement This process is repeated until all catheter tubes are successfully placed, ensuring that the necessary devices are in position for the subsequent interstitial radioelement application.

3. Post-Procedure

After the completion of the needle or catheter placement, post-procedure care is essential to monitor the patient for any complications and to ensure the proper functioning of the inserted devices. Patients may be observed for signs of infection, bleeding, or any adverse reactions related to the procedure. Follow-up imaging may be required to confirm the correct placement of the needles or catheters. Additionally, instructions regarding activity restrictions and care of the insertion sites may be provided to the patient to facilitate recovery and minimize risks. The subsequent application of interstitial radioelements will be scheduled as part of the overall treatment plan, which is reported separately.

51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
