CPT® Code 49186

Excision or destruction, open, intra-abdominal (ie, peritoneal, mesenteric, retroperitoneal), primary or secondary tumor(s) or cyst(s), sum of the maximum length of tumor(s) or cyst(s); 5 cm or less

The procedure described by CPT® Code 49186 involves the open excision or destruction of intra-abdominal tumors or cysts, which can be either primary or secondary in nature. This means that the tumors may originate in the abdominal cavity or may have spread from other parts of the body. The excision can be performed through surgical techniques that either completely remove the tumor or destroy it using methods such as electrocautery or laser ablation. The surgical approach requires making an incision in the abdomen, allowing access to the peritoneum, which is the membrane lining the abdominal cavity. Care is taken to avoid damaging surrounding structures, including the bowel and other internal organs, during the procedure. Once the peritoneal cavity is accessed, the surgeon can explore the abdominal cavity thoroughly, identifying and assessing any masses or abnormalities present. The procedure is meticulous, requiring careful dissection and retraction to ensure that all tumors or cysts are adequately addressed while preserving the integrity of surrounding tissues and blood vessels. The final steps involve irrigating the abdominal cavity, inspecting for any potential injuries, and properly closing the incision to promote healing.
