CPT® Code 15278

Add-On Code

Application of skin substitute graft to face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, and/or multiple digits, total wound surface area greater than or equal to 100 sq cm; each additional 100 sq cm wound surface area, or part thereof, or each additional 1% of body area of infants and children, or part thereof (List separately in addition to code for primary procedure)

The CPT® Code 15278 refers to the application of a skin substitute graft specifically designed for extensive wounds located on various anatomical sites, including the face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, and multiple digits. This procedure is indicated when the total wound surface area is greater than or equal to 100 square centimeters. Skin substitutes are advanced medical products that can be composed of acellular bioengineered constructs or allogeneic cells, and they are utilized to facilitate the healing process of open wounds. These wounds may arise from various conditions such as burns, skin donor sites, diabetic ulcers, venous ulcers, or other chronic wounds that are difficult to heal. The skin substitutes used in this procedure can include a range of products, such as acellular dermal allografts, tissue cultured allogeneic skin substitutes, tissue cultured allogeneic dermal substitutes, and acellular xenografts. Acellular dermal allografts are derived from cadaver donors and have undergone chemical treatment to remove antigenic epidermal cellular components, making them suitable for transplantation. Tissue cultured allogeneic skin substitutes consist of two layers: an upper layer of human keratinocytes that form the epidermis and a lower layer of human fibroblasts cultured on a collagen matrix. Tissue cultured allogeneic dermal substitutes are created using fibroblast cells from newborn foreskin tissue, which are seeded onto a bioabsorbable mesh scaffold, allowing for the growth of living cells that secrete essential components for skin regeneration. Acellular xenografts, on the other hand, are sourced from other species, typically pigs or cows, and are processed to remove cellular material, resulting in a graft composed of acellular collagen and elastin fibers. The application of these skin substitutes involves specific procedural steps that vary depending on the type of graft used, ensuring that the wound is adequately covered and secured to promote optimal healing.
