Summary & Overview
HCPCS Q4371: Neoguard per Square Centimeter (Add-on Supply)
HCPCS Level II code Q4371 designates Neoguard billed per square centimeter as an add-on supply item reported in addition to a primary procedure. This code matters nationally because it standardizes reporting for an area-based surgical or wound-care product, enabling consistent claims processing, product-specific tracking, and more accurate costing for procedures that require coverage of tissue or wound surfaces.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines which payers commonly recognize add-on supply codes, how Q4371 fits into clinical workflows for surgical and wound-care services, and where stakeholders should look for coverage policies and reimbursement guidance.
Readers will find benchmarks and coding guidance relevant to billing and documentation, a summary of clinical contexts in which Neoguard is used, and an overview of policy considerations that affect claim adjudication for add-on supply codes. Where payer-specific policy details are not provided in the input, the report notes that data is not available. The content is intended for coding professionals, revenue cycle managers, and clinicians who need a concise national view of HCPCS Level II code Q4371 and its role in procedure-related supply reporting.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a chronic, non-healing full-thickness or partial-thickness wound (for example, a diabetic foot ulcer, venous stasis ulcer, or complex traumatic soft-tissue defect) requiring adjunctive dermal matrix or biologic graft material. The clinical workflow begins with wound assessment by a surgeon or wound care specialist, debridement of necrotic tissue, hemostasis, and wound bed preparation. Q4371 (Neoguard, per square centimeter) is applied as an add-on product to augment soft-tissue coverage or promote dermal regeneration during the same operative or procedural encounter. The product is measured and billed per square centimeter in addition to the primary procedure. Typical sites of service include hospital outpatient departments, ambulatory surgery centers, and office-based procedure suites. Common patient factors include diabetes, peripheral vascular disease, prior radiation, infection under control, or inadequate soft tissue for primary closure.
