HCPCS Level II code Q4107 designates billing for Graftjacket, per square centimeter, reported as an add-on code in addition to a primary surgical procedure. This code captures the supply and application of an engineered graft material used in wound repair or surgical reconstruction and matters nationally because product-specific supply codes affect claim adjudication, coding consistency, and payment for implantable biologic materials across inpatient and outpatient procedural settings. Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find an overview of clinical and billing context for Q4107, including how the code is used alongside primary surgical procedure codes, typical sites of service where the graft is applied, and implications for coding workflows. The publication summarizes available benchmarks and payer coverage considerations, highlights common modifiers reported with procedural supply add-on codes, and outlines policy and documentation factors that influence reimbursement. Where payer-specific coverage details are not available in the input, the report notes that data are not provided. The focus is national in scope and intended for coding professionals, revenue cycle teams, and clinical staff involved in procedural supply documentation and billing.
