Acellular xenograft implant; each additional 100 sq cm, or each additional 1% of body area of infants and children, or part thereof (List separately in addition to code for primary procedure)

An acellular xenograft implant is a specialized medical procedure utilized to cover wounds or skin defects. This type of implant is derived from skin or other tissues obtained from a different species, commonly porcine (pig). The term "acellular" indicates that the cells, cell debris, DNA, and RNA have been meticulously removed from the tissue. This process significantly reduces the likelihood of rejection by the recipient's immune system, allowing the implant to function effectively as a permanent solution for skin or soft tissue restoration. The composition of the acellular xenograft includes animal-derived collagen and elastin fibers, which undergo a cross-linking treatment to enhance their durability and prevent breakdown or reabsorption by the body. During the procedure, the xenograft implant is carefully removed from its packaging, tailored to fit the specific dimensions of the wound, and then applied to the prepared wound bed. It is secured in place using sutures to ensure proper adherence and facilitate healing. For billing purposes, CPT® Code 15430 is used for the initial coverage of up to 100 square centimeters in adults or up to 1% of total body surface area (TBSA) in infants and children, while CPT® Code 15431 is designated for each additional 100 square centimeters in adults or each additional 1% of TBSA in infants and children, or any part thereof.
