Summary & Overview
HCPCS Q4157: Revitalon, per Square Centimeter (Add-on)
HCPCS Level II code Q4157 denotes Revitalon billed per square centimeter as an add-on supply to be listed in addition to a primary procedure. Nationally, add-on product and supply codes like Q4157 matter because they affect bundled payment calculations, surgical supply reporting, and documentation of adjunctive therapies that support procedural outcomes. Proper use of this code ensures that the cost of topical revitalization products applied during a procedure is captured separately from the primary procedure.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the product, typical sites of service where the code is used, and what to expect in payer coverage behavior. The publication outlines benchmarks for utilization where available, common billing modifiers (listed separately), and policy considerations around add-on HCPCS coding and documentation requirements.
This summary serves clinicians, coding professionals, and policy analysts seeking a national perspective on how HCPCS Level II code Q4157 is applied, documented, and reviewed by major public and private payers. Data not available in the input where specific payer policies, utilization statistics, or associated ICD-10 diagnoses would normally be listed.

Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an adult with a full-thickness skin defect or chronic non-healing wound undergoing surgical debridement and placement of a topical regenerative skin matrix product, billed as Q4157 (Revitalon, per square centimeter) as an add-on supply to the primary wound procedure. The service is commonly provided in an outpatient ambulatory surgery center, hospital outpatient department, or clinic procedure room under local anesthesia with or without sedation. A wound care or reconstructive clinic documents wound measurements in square centimeters to calculate units of Q4157 applied. The clinical workflow includes wound assessment, photographic documentation, debridement or preparation of wound bed, application of the Revitalon matrix to the measured wound area, dressing placement, and patient education for dressing care and follow-up. Typical patients include those with chronic diabetic foot ulcers, venous stasis ulcers, pressure injuries, or traumatic skin loss requiring biologic or synthetic regenerative matrices as adjunctive therapy to promote epithelialization and wound closure.
