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); 20.1 to 30 cm

Open excision or destruction of intra-abdominal tumors or cysts involves a surgical procedure where an incision is made in the abdomen to access and treat tumors or cysts located within the peritoneal, mesenteric, or retroperitoneal areas. These tumors can be classified as either primary, originating from the abdominal organs, or secondary, which have spread from other parts of the body. The procedure may involve complete excision of the tumor or cyst, or it may utilize techniques such as electrocautery or laser ablation to destroy the tumor tissue. The surgical approach requires careful dissection to avoid damaging surrounding structures, including the bowel and other vital organs. Once the abdominal cavity is opened, the surgeon will explore the area visually and by palpation to identify all masses and abnormalities. The procedure is meticulous, ensuring that blood vessels supplying adjacent organs are preserved during tumor resection. After the tumors or cysts are addressed, the abdominal cavity is thoroughly irrigated, inspected for any potential injuries, and the organs are returned to their anatomical positions before closure. This procedure is indicated for tumors or cysts with a combined maximum length ranging from 20.1 to 30 cm, and specific coding is required based on the size of the tumors or cysts being treated.
