Clinical & Coding Specifications
Clinical Context
A 54-year-old patient with a full-thickness skin defect following wide excision of a chronic non-healing lower-extremity ulcer is evaluated in an outpatient surgical center. After debridement and wound bed preparation, the reconstructive team determines that a biologic cellular skin substitute is appropriate to promote re-epithelialization. The facility prepares a measured area of Axolotl dualgraft ultra product billed per square centimeter using Q4384 as an add-on item in conjunction with the primary surgical wound repair or grafting procedure. The typical workflow includes preoperative sizing and documentation of the wound surface area in square centimeters, ordering the Axolotl product from the supplier (unit documented by cm2), application in the operating or procedure room by the surgeon and surgical team, securement of the graft, and routine postoperative dressing changes and wound assessments during follow-up visits. This service is most often delivered in an outpatient hospital-based ambulatory surgery center or specialized wound care clinic where sterile application and appropriate postoperative monitoring can occur.
