Summary & Overview
HCPCS Q4298: Amniocore pro, per square centimeter
HCPCS Level II code Q4298 designates the Amniocore pro product charged per square centimeter as an add-on supply used during procedures that apply an amniotic membrane. This code matters nationally as use of biologic and tissue-based products grows across ophthalmology, wound care, and reconstructive procedures, affecting billing practices and supply-line reimbursement. The code is additive and must be reported in conjunction with a primary procedure when the material is used.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s clinical context and common sites of service, a breakdown of typical payer coverage considerations, and guidance on where this code fits in service-line reporting. The publication outlines benchmarks and policy-relevant points such as add-on billing implications, typical billing modifiers (listed separately), and common payer interactions that influence reimbursability and claim adjudication. It also flags where input data was not provided.
This piece is intended for a national audience of billing managers, clinical coders, and policy analysts seeking concise, practical context for incorporating HCPCS Level II code Q4298 into procedure-level billing workflows and payer communications.

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with a chronic, non-healing lower extremity wound following peripheral vascular insufficiency presents to a wound care clinic. The provider evaluates the wound, performs debridement as needed, and applies an amniotic membrane product (Q4298) sized and charged per square centimeter as an adjunctive biologic graft to promote healing. The typical clinical workflow includes wound assessment, cleansing, sharp or enzymatic debridement if indicated, measurement of wound surface area, selection and preparation of the amniotic product, placement and securement of the graft, and application of appropriate dressings. Follow-up visits occur at defined intervals to assess graft take, wound contraction, and need for reapplication or additional interventions. Typical sites of service include outpatient wound care clinics, ambulatory surgical centers, hospital outpatient departments, and skilled nursing facilities when performed as part of an advanced wound care regimen.
