CPT® Code 19303

A simple, complete mastectomy, designated by CPT® Code 19303, is a surgical procedure aimed at the removal of breast tissue along with the overlying skin, while intentionally excluding lymph nodes and muscle. This procedure is typically indicated for patients requiring a definitive surgical intervention for breast conditions, such as malignancies or other significant breast pathologies. The surgical approach involves making a curved incision beneath the breast, which allows for the excision of breast tissue extending into the axillary region, known as the tail of Spence. During the operation, the surgeon meticulously separates the skin from the underlying breast tissue, which is then carefully dissected away from the muscle fascia and sternum. The entire breast tissue, including the skin and nipple, is excised in its entirety. Following the removal, a drain tube may be inserted to facilitate the drainage of any excess fluid, and the skin edges are subsequently reapproximated and closed to promote healing. This procedure is crucial for patients who require complete removal of breast tissue for therapeutic reasons, ensuring that the affected area is adequately addressed while minimizing the risk of complications associated with more extensive surgical techniques.
