C5274 Low-Cost Skin Substitute Graft Reimbursement | OpenPayer

Summary & Overview

HCPCS C5274: Low Cost Skin Substitute Graft, Additional 100 sq cm

HCPCS Level II code C5274 denotes the add-on application of a low cost skin substitute graft for additional wound surface area on the trunk, arms, or legs when the total area is greater than or equal to 100 sq cm (or each additional 1% of body area for infants and children). This code matters nationally because it standardizes billing for incremental surface-area-based grafting procedures, affecting reimbursement for larger or pediatric wounds and informing facility and payer claims processes. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context for use of C5274, how it functions as an add-on code to primary skin substitute procedures, and the typical sites of service where it is encountered. The publication provides benchmarks and policy-oriented context relevant to billing practices, documentation expectations tied to surface area measurement, and common payer coverage considerations. Data not available in the input includes specific reimbursement rates, associated taxonomies, and ICD-10 diagnosis pairings; where those elements are missing, this summary notes the absence. The content is intended for national stakeholders — revenue cycle leaders, wound care clinicians, and policy analysts — seeking a concise reference on billing and clinical implications of add-on surface-area reporting for low cost skin substitute grafts.

Billing Code Overview

HCPCS Level II code C5274 describes the application of a low cost skin substitute graft to the trunk, arms, or legs for a total wound surface area greater than or equal to 100 square centimeters. The code is reported for each additional 100 square centimeters, or part thereof, and specifically notes an alternative reporting metric for infants and children as each additional 1% of body area, or part thereof. This procedure is an add-on service reported in addition to the primary skin substitute graft procedure when larger surface areas require incremental billing.

Service Type: Skin substitute graft application (low cost), add-on for additional surface area

Typical Site of Service: Hospital outpatient settings, ambulatory surgical centers, and specialized wound care clinics

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult with a large full-thickness or mixed-depth wound of the trunk or an extremity following trauma, infection debridement, or chronic nonhealing ulceration (for example, a large traumatic soft-tissue avulsion of the thigh after a motor vehicle collision). The surgical team (general surgery, plastic surgery, or wound care service) performs wound bed preparation including debridement, hemostasis, and measurement of total wound surface area. A low-cost skin substitute graft product is applied to cover the wound surface area ≥100 sq cm as part of definitive coverage or to promote granulation prior to delayed autografting.

The clinical workflow includes initial evaluation and stabilization, wound measurement and photography, operative debridement in the operating room or procedure suite under appropriate anesthesia, application of the skin substitute graft to the prepared wound, fixation or dressing of the graft, and postoperative dressing changes with outpatient wound care follow-up. Documentation must include wound size (sq cm or % body surface for pediatric patients), product name, application technique, number of additional 100 sq cm increments (or additional 1% body area for infants/children) billed with C5274, and any complications or unusual circumstances that would justify modifier use.
