CPT® Code 49327

Add-On Code

Laparoscopy, surgical; with placement of interstitial device(s) for radiation therapy guidance (eg, fiducial markers, dosimeter), intra-abdominal, intrapelvic, and/or retroperitoneum, including imaging guidance, if performed, single or multiple (List separately in addition to code for primary procedure)

The procedure described by CPT® Code 49327 involves the laparoscopic surgical placement of interstitial devices, which are critical for guiding radiation therapy. These devices, including fiducial markers and dosimeters, are strategically positioned within the intra-abdominal, intrapelvic, or retroperitoneal areas to enhance the precision of radiation treatment. Fiducial markers, often made of gold, serve as reference points that allow radiation oncologists to accurately target malignant tumors while minimizing exposure to adjacent healthy tissues. This is essential in ensuring that the radiation is concentrated on the tumor, thereby maximizing treatment efficacy and reducing potential side effects. Implantable dosimeters, on the other hand, are utilized to measure the radiation dose delivered at the tumor site, providing valuable data for treatment planning and adjustment. The laparoscopic approach allows for minimally invasive access to the targeted areas, where imaging guidance is employed to confirm the correct placement of these devices. The procedure concludes with the removal of the laparoscope and trocars, followed by the closure of the incisions, ensuring a swift recovery for the patient.
