CPT® Code 49321

The procedure described by CPT® Code 49321 refers to a laparoscopic surgical technique that involves the use of a laparoscope to perform a biopsy. This minimally invasive procedure begins with the placement of a periumbilical port, which is a small incision made near the belly button. Through this port, pneumoperitoneum is established, meaning that air is insufflated into the abdominal cavity to create a working space for the surgeon. The laparoscope, equipped with a video camera, is then inserted, allowing for a visual inspection of the entire abdominal cavity, including the peritoneum and omentum. This inspection is crucial for identifying any signs of malignancy, disease, or injury. During the procedure, biopsy forceps are introduced through the laparoscope to obtain tissue samples from one or multiple sites within the abdominal cavity. These samples are subsequently sent to a laboratory for histologic evaluation, which is reported separately. After the biopsy is completed, the surgeon inspects the biopsy sites for any bleeding, which is controlled using laser or electrocautery if necessary. Finally, the instruments are withdrawn, and pressure is applied to the abdomen to expel any remaining air from the peritoneum before closing the portal incisions. This procedure is essential for diagnosing various abdominal conditions while minimizing recovery time and complications associated with more invasive surgical techniques.
