CPT® Code 44820

The excision of a lesion of the mesentery, as described by CPT® Code 44820, refers to a surgical procedure targeting the mesentery, which is a vital structure in the gastrointestinal tract. The mesentery is a fan-shaped fold of tissue that supports the intestines and contains essential blood vessels, lymphatics, and nerves that supply the intestinal organs. Lesions or tumors that may develop in the mesentery can vary in nature, being either cystic or solid, and can be classified as benign or malignant. During the procedure, an incision is made in the abdomen to access the mesentery, allowing the surgeon to carefully examine the area for any additional masses or abnormalities that may not have been previously identified. Once the lesion is located, it is excised along with a margin of healthy tissue to ensure complete removal and minimize the risk of recurrence. The excised tissue is then sent to a laboratory for pathological evaluation, which is crucial for determining the nature of the lesion. After the excision, the surgical site is irrigated to prevent infection, bleeding is controlled, and the incisions are closed to promote healing.
