What Q4182 covers
Q4182 identifies TransCyte, a temporary skin substitute used to cover wounds, including burn wounds and donor sites. Burn surgeons and other clinicians performing wound care may use it during treatment that applies a skin substitute to the affected area. The product code represents the TransCyte material; the related application procedure describes the work of placing the substitute on the wound.
Report Q4182 only with a primary procedure, not as a stand-alone service. Select the primary application code for the treated site and wound area, and document the wound location, treated area, product used, and quantity in square centimeters. CMS classifies Q4182 as an add-on code paid within the primary procedure's global period. It is technical-component-only; a separate code covers interpretation.
