HCPCS Q4407: Xwrap tribus, Add-on Implantable Material per sq cm
HCPCS Level II code Q4407 designates the Xwrap tribus product billed per square centimeter as an add-on to a primary surgical procedure. As an add-on device/material code, it identifies use of a specific adjunctive implantable or surgical material that is reported separately from the primary procedure code. Nationally, accurate reporting of add-on HCPCS codes like Q4407 matters for appropriate payment, inventory management, and surgical supply tracking.
Key payers covered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context for use of this add-on product, the typical sites of service where it is applied, and the implications for billing and claims submission. The publication also addresses benchmarks and coverage patterns where available, common documentation needs for add-on surgical materials, and any recent policy updates relevant to HCPCS add-on coding.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a complex wound of the lower extremity (e.g., chronic diabetic foot ulcer or post-traumatic soft-tissue defect) requiring surgical coverage augmentation. In the ambulatory surgical center or hospital operating room, the surgeon debrides nonviable tissue, prepares the wound bed, and applies an extracellular matrix skin substitute product — specifically the Xwrap Tribus product — sized and trimmed to the defect. The product is billed as an add-on per square centimeter using Q4407 in addition to the primary wound repair or grafting procedure. The multidisciplinary workflow commonly includes preoperative assessment by the surgeon and wound care team, intraoperative measurement of the defect to document square centimeters of product used, photographic documentation and charting of product lot numbers, and postoperative dressing changes with scheduled wound clinic follow-up for evaluation of integration and healing.
