Fractional ablative laser fenestration of burn and traumatic scars for functional improvement; each additional 100 cm2, or each additional 1% of body surface area of infants and children, or part thereof (List separately in addition to code for primary procedure)

Fractional ablative laser fenestration is a specialized medical procedure designed to improve the functional outcomes of patients with burn and traumatic scars. These types of scars can lead to contractures, which are caused by adhesions and the binding of underlying tissue layers. This condition often results in reduced elasticity, limited range of motion, and various functional deficits that can significantly impact a patient's quality of life. The procedure involves the use of a laser to create microscopic full-thickness wounds in the scar tissue, effectively removing damaged epithelial layers and reducing excessive collagen fibers that contribute to the scar's rigidity. As the body heals, thinner collagen bundles and granulation tissue form in the treated areas, allowing the epidermis to regenerate in a manner that remodels the scar, resulting in a smoother appearance and improved functionality. Prior to the procedure, the area to be treated is anesthetized using either a topical cream or a local injection to minimize discomfort. The laser settings are tailored to each patient's needs, with the treatment depth adjusted according to the thickness of the scar. The application of the laser is performed in a non-overlapping stamping pattern, creating narrow columns that ensure effective treatment. The specific wavelength of the laser is absorbed by the fluid present in the tissue, leading to vaporization and leaving a thin rim of coagulation around the treated areas. This procedure is reported using CPT® Code 0479T for the first 100 cm2 or part thereof, or 1% of body surface area of infants and children, while CPT® Code 0480T is used to report each additional 100 cm2 or 1% of body surface area of infants and children, or part thereof.
