Summary & Overview
HCPCS Level II Q4277: Woundplus Membrane or E-Graft, per sq cm
HCPCS Level II code Q4277 denotes billing for the Woundplus membrane or e-graft measured per square centimeter, a biologic product used in wound management and soft-tissue regeneration. This code is relevant nationally as use of biologic membranes grows for chronic wounds, surgical wound support, and complex soft-tissue defects; proper coding affects billing accuracy and product utilization tracking.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines which payers recognize the code, common billing modifiers in use for related services, and where data is unavailable. Readers will find benchmarking context for pricing and coverage patterns, an explanation of clinical scenarios where a wound membrane or e-graft is used, and operational considerations for documenting surface-area–based products. The summary highlights coding conventions for per-square-centimeter products, the typical sites of service where these products are applied (outpatient wound clinics, hospital outpatient departments, and ambulatory surgical centers), and notes on payer variability. Data not provided in the input—such as associated taxonomies, specific ICD-10 diagnoses, and related codes—is identified as "Data not available in the input."

Clinical & Coding Specifications
Clinical Context
A typical patient receiving Q4277 is an adult with a non-healing full-thickness or complex partial-thickness skin defect such as a chronic diabetic foot ulcer, venous stasis ulcer, or a surgical dehiscence where advanced biologic wound matrix therapy is indicated. The wound is measured in square centimeters and the Q4277 product (Woundplus membrane or e-graft) is applied in the outpatient wound clinic, specialty clinic, or ambulatory surgery center.
Clinical workflow: the wound is assessed and measured, appropriate debridement is performed (sharp, mechanical, or enzymatic) and infection control measures addressed. Hemostasis is obtained, the site is prepared with sterile technique, and the Q4277 membrane is trimmed to size and applied to the wound bed. The graft is secured with sutures, staples, adhesive, or secondary dressing as clinically indicated. Post-application dressing and patient instructions are provided, and follow-up visits are scheduled for assessment, dressing changes, and possible reapplication. Providers typically document size in square centimeters, indication, debridement performed, vascular status, infection status, and precise product units billed as Q4277 per square centimeter.
