CPT® Code 49190

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); greater than 30 cm

The procedure described by CPT® Code 49190 involves the open excision or destruction of intra-abdominal tumors or cysts, which can be either primary or secondary in nature. This surgical intervention is indicated for tumors or cysts that exceed a cumulative maximum length of 30 centimeters. The approach is invasive, requiring an incision in the abdominal wall to access the peritoneal cavity. During the procedure, the surgeon carefully navigates around vital structures such as the bowel, kidneys, and blood vessels to minimize the risk of injury. The tumors or cysts may be completely excised, meaning they are surgically removed in their entirety, or they may be destroyed using techniques such as electrocautery or laser ablation. This method allows for the effective treatment of large masses while ensuring thorough exploration of the abdominal cavity to identify and address any additional abnormalities. The procedure is comprehensive, involving meticulous dissection, irrigation, and careful closure to promote optimal recovery and minimize complications.
