CPT® Code 55920

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

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.
