CPT® Code 21743

The CPT® Code 21743 refers to a reconstructive surgical procedure specifically designed to address pectus excavatum or pectus carinatum, utilizing a minimally invasive approach known as the Nuss procedure. This procedure is performed under general anesthesia and involves making two lateral incisions on either side of the chest. The primary goal of this surgery is to correct the deformity of the chest wall, which can lead to both cosmetic concerns and potential respiratory issues. During the procedure, a specially designed curved steel bar is inserted beneath the sternum to elevate the depressed area of the chest in cases of pectus excavatum or to depress the protruding area in cases of pectus carinatum. A thoracoscope, which is a type of endoscope, is introduced through a separate incision to provide direct visualization of the surgical field, ensuring precision as the bar is positioned. The bar is custom-shaped for each patient to effectively restore the normal contour of the chest wall. Once the bar is in place, it is secured to the ribs on either side, and the incisions are meticulously closed and dressed to promote healing. In some cases, a small steel, grooved plate may be utilized at the end of the bar to enhance stability and fixation to the rib, further ensuring the success of the procedure. This minimally invasive technique is associated with reduced recovery times and less postoperative pain compared to traditional open surgical methods.
