CPT® Code 49323

Laparoscopy, surgical; with drainage of lymphocele to peritoneal cavity, as described by CPT® Code 49323, refers to a minimally invasive surgical procedure aimed at addressing a lymphocele, which is a collection of lymphatic fluid that accumulates in the retroperitoneal space, behind the peritoneum. This condition often arises following surgical interventions or trauma that disrupts the normal flow of lymphatic fluid, leading to its accumulation. The procedure involves the use of a laparoscope, a specialized instrument equipped with a camera, which allows the surgeon to visualize the internal structures of the abdomen without the need for large incisions. During the procedure, a small incision is made near the umbilicus to insert the laparoscope, and the abdomen is inflated with gas to create a working space. Additional small incisions are made to insert trocars, through which surgical instruments are introduced. The surgeon then exposes and incises the posterior peritoneum, creating a fenestration that facilitates the drainage of lymphatic fluid from the retroperitoneal space into the peritoneal cavity. This drainage is crucial for alleviating the pressure and symptoms associated with the lymphocele. The procedure concludes with the removal of surgical instruments, deflation of the abdomen, and closure of the incisions with sutures, ensuring minimal scarring and a quicker recovery for the patient.
