Summary & Overview
HCPCS C5277: Low Cost Skin Substitute Graft Application, ≥100 sq cm
HCPCS Level II code C5277 designates the application of a low cost skin substitute graft for large or multiple-area wounds measuring at least 100 square centimeters (or 1% of body area in infants and children), covering the first 100 sq cm of treated surface. This procedure code is relevant across surgical, wound care, and burn management settings and affects national billing, coverage determinations, and care pathways for patients requiring biologic or engineered skin substitutes.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context, common sites of service, and payer coverage considerations. The publication outlines benchmarking elements commonly examined for this code, summarizes relevant policy themes insurers address when reviewing skin substitute claims, and provides clinicians and billing specialists with concise guidance on documentation and service characterization associated with large-surface-area applications.
This national-level summary is designed to inform healthcare administrators, coding professionals, and clinicians about the role of C5277 in treatment of extensive wounds, typical care settings, and the payer landscape relevant to authorization and claims processing. Data not available in the input are identified where applicable in the full publication.
Billing Code Overview
HCPCS Level II code C5277 describes the application of a low cost skin substitute graft to areas including the face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, and/or multiple digits. The code applies when the total wound surface area is greater than or equal to 100 sq cm and covers the first 100 sq cm of wound surface area, or 1% of body area for infants and children.
Service type: Skin substitute graft application for large or multiple-area wounds.
Typical site of service: Hospital outpatient departments, ambulatory surgical centers, burn centers, specialty wound care clinics, and inpatient operating rooms, depending on clinical setting and patient needs.
Clinical & Coding Specifications
Clinical Context
A 58-year-old male presents to the outpatient burn/plastic surgery clinic with a full-thickness debridement wound of the right hand and dorsal forearm after a thermal injury. Total wound surface area measures 120 sq cm and involves multiple digits and the dorsum of the hand. The patient previously underwent operative debridement and tangential excision in the operating room under monitored anesthesia care. The surgeon selects a low-cost skin substitute graft to cover the extensive area as a biologic dressing to promote re-epithelialization and reduce donor-site morbidity.
The clinical workflow: the patient arrives to the ambulatory surgery center (ASC) or hospital outpatient department (HOPD) on the scheduled day. Pre-operative verification, informed consent, and photographic wound documentation are performed. In the OR, under appropriate anesthesia, the wound bed is prepared and hemostasis achieved. The low-cost skin substitute is measured and applied to cover the first 100 sq cm of wound surface area per C5277 guidance. Dressings and splinting are applied. Post-operatively the patient is observed in recovery, given wound care and dressing instructions, and scheduled for follow-up visits for graft take assessment, dressing changes, and potential additional applications if remaining wound area exceeds covered surface or further interventions are required.
