CPT® Code 49062

An extraperitoneal lymphocele refers to a collection of lymphatic fluid that accumulates in the retroperitoneal space, which is located behind the peritoneum, the membrane lining the abdominal cavity. This condition often arises as a result of surgical interventions or trauma that disrupts the normal flow of lymphatic fluid, leading to its accumulation. The procedure coded as CPT® 49062 involves the surgical drainage of this fluid collection by creating an opening in the abdominal wall. During the operation, the surgeon makes an incision to access the abdominal cavity and exposes the posterior aspect of the peritoneum. A careful incision is then made in the posterior peritoneum to create a small window, known as fenestration, which facilitates the drainage of lymphatic fluid from the retroperitoneal space into the peritoneal cavity. This fenestration is intentionally left open to ensure continuous drainage, and the abdominal incision is subsequently closed. This procedure is critical for alleviating symptoms associated with lymphocele and preventing complications that may arise from fluid accumulation.
