HCPCS Q4253: Zenith Amniotic Membrane, Per Square Centimeter
HCPCS Level II code Q4253 identifies the Zenith amniotic membrane billed per square centimeter as an add-on supply used alongside a primary surgical or wound care procedure. Nationally, this code matters because it standardizes reporting for a biologic graft product that can influence procedural supplies, cost accounting, and billing consistency across ambulatory surgery centers, hospital operating rooms, and wound clinics. Clear use of Q4253 aids payers and providers in adjudicating claims involving amniotic membrane products.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines what readers will learn about the code’s clinical context, typical sites of service, and billing treatment as an add-on supply. It also summarizes available benchmarks and policy-relevant considerations where present. Where specific payer policy details or utilization benchmarks are not provided in the input, the report notes that data is not available in the input.
Readers will gain: a concise clinical description of the product and its common use cases; the service line and typical settings where the code is applied; an inventory of common modifiers associated with this code as provided; and guidance on which payer types are relevant for national billing and coverage discussions. The content is designed for revenue cycle managers, clinicians involved in surgical supply selection, and policy analysts monitoring biologic graft billing practices.

Clinical & Coding Specifications
Clinical Context
A patient with a non-healing corneal epithelial defect or ocular surface disorder presents to an outpatient ophthalmology clinic or ambulatory surgical center for placement of an amniotic membrane graft using Zenith brand amniotic membrane sized and billed per square centimeter. Typical patients are older adults or individuals with ocular surface disease (for example, persistent epithelial defects after herpetic keratitis, severe dry eye with epithelial breakdown, neurotrophic keratitis, or chemical/thermal injury) who have failed conservative management such as topical lubricants, autologous serum, or bandage contact lens.
The clinical workflow begins with a comprehensive ophthalmic evaluation, including slit-lamp exam and measurement of the epithelial defect. After informed consent, procedure indications and size are documented. In the procedure room or minor procedure suite, topical and/or local anesthesia is administered; the ocular surface is prepared; any devitalized epithelium or scar tissue is debrided; the Zenith amniotic membrane is sized and trimmed to the defect (measured in cm2) and secured with sutures, tissue adhesive, or a bandage contact lens. Post-procedure care includes topical antibiotics and anti-inflammatory agents, specific activity restrictions, and scheduled follow-up to monitor epithelialization and membrane integration. Billing uses add-on code Q4253 reported per square centimeter in addition to the primary ocular surface repair procedure code.
