CPT® Code 15150

A tissue cultured skin autograft is a specialized surgical procedure utilized to cover defects located on the trunk, arms, or legs of a patient. This technique involves the harvesting of epidermal tissue from the patient, which is then processed in a laboratory setting. The harvested tissue is separated from dermal cells and cultured in an incubator, allowing the epidermal cells, known as keratinocytes, to proliferate. These cells are provided with essential nutrients to facilitate their growth into sheets of skin suitable for grafting. Once the cultured epidermal tissue is ready, it is placed in a transport medium and returned to the medical facility where the grafting procedure will take place. During the procedure, the physician carefully removes the graft from the transport medium and positions it over the prepared wound bed at the recipient site. The graft is then secured in place using interrupted sutures around its edges, although alternative methods such as staples or fibrin sealant may also be employed. This specific code, 15150, is applicable for grafts measuring 25 square centimeters or less, while additional codes are available for larger graft sizes.
