CPT® Code 15778

Implantation of absorbable mesh or other prosthesis for delayed closure of defect(s) (ie, external genitalia, perineum, abdominal wall) due to soft tissue infection or trauma

The procedure described by CPT® Code 15778 involves the implantation of absorbable mesh or other prosthetic materials to facilitate the delayed closure of defects that may occur in areas such as the external genitalia, perineum, or abdominal wall. These defects typically arise due to soft tissue infections, such as necrotizing soft tissue infections (NSTI), or as a result of trauma. In cases where there is significant tissue loss, particularly following extensive debridement, the use of absorbable mesh becomes essential for effective closure and healing. The procedure is particularly relevant for patients who present with large defects in the abdominal wall, which may result from severe infections that necessitate the removal of compromised skin, subcutaneous tissue, fascia, and muscle. The implantation of the mesh or prosthetic material is performed using various surgical techniques tailored to the specific defect and its location. These techniques include underlay, onlay, inlay, and wrap-around methods, each designed to provide optimal support and facilitate healing of the affected area. The mesh is carefully shaped and positioned to ensure adequate coverage and stability of the defect, promoting recovery and minimizing complications.
