Official Description

Mastectomy, subcutaneous

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A subcutaneous mastectomy, as defined by CPT® Code 19304, is a surgical procedure that involves the removal of breast tissue while preserving the underlying muscle and skin. This procedure is typically indicated for patients who may require mastectomy due to various conditions, such as breast cancer or other breast abnormalities, but who wish to maintain the integrity of the skin and muscle structure. The surgery begins with an incision made along the inframammary crease, which is the natural fold beneath the breast. This strategic incision allows the surgeon to access the breast tissue effectively. During the procedure, the surgeon carefully dissects the breast tissue from the underlying muscle fascia and skin, ensuring that the muscle remains intact. Prior to the removal of the breast tissue, the skin may be examined for any pathological conditions that could warrant further intervention. After the breast tissue is excised, the nipple and areola are repositioned and sutured back into place. To facilitate recovery and prevent complications, a suction catheter or drainage tube is often inserted to manage any fluid accumulation. Additionally, a prosthesis may be placed under the skin to provide aesthetic support before the surgical site is closed. This procedure is particularly beneficial for patients seeking a less invasive option while addressing their medical needs.
