Summary & Overview
HCPCS Q4102: Oasis Wound Matrix, Per Square Centimeter
HCPCS Level II code Q4102 designates the Oasis wound matrix billed per square centimeter as an add-on supply used in advanced wound care procedures. This code matters nationally because it standardizes reporting for a widely used biologic scaffold product that supports tissue regeneration in chronic and complex wounds. Accurate coding affects clinical documentation, supply cost tracking, and payer coverage determinations across multiple outpatient settings.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical purpose and typical sites of service, followed by benchmarking and policy context relevant to coverage and billing for add-on wound matrix supplies. The publication outlines common billing considerations, claim-line reporting expectations, and where to look for payer-specific coverage policies. It emphasizes documentation elements that support medical necessity for advanced wound therapies.
This resource is intended for billing managers, revenue cycle staff, clinical coders, and clinicians involved in wound care to clarify the code’s use, identify where to check payer policies, and understand implications for outpatient billing and reimbursement processes.
Billing Code Overview
HCPCS Level II code Q4102 describes Oasis wound matrix, billed per square centimeter, intended as an add-on supply item to be listed separately in addition to the primary procedure. The service type is a wound care graft/matrix application used to support tissue repair in open or chronic wounds. The typical site of service for this supply is outpatient wound care settings, which can include hospital outpatient departments, ambulatory surgery centers, specialized wound clinics, and outpatient physician offices that provide advanced wound therapies.
Service details beyond the supplied description (such as associated taxonomies, specific ICD-10 diagnoses, or related procedure codes) are not provided.
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a chronic, non-healing full- or partial-thickness wound such as a diabetic foot ulcer, venous stasis ulcer, or surgical dehiscence. The wound has failed conservative therapy (dressings, offloading, compression) and requires biologic matrix placement to promote granulation and re-epithelialization. In an outpatient wound clinic or ambulatory surgical center, the provider performs wound bed preparation including debridement, irrigation, and hemostasis. After adequate hemostasis and a clean granulating base are achieved, the provider measures the wound area in square centimeters and applies Q4102 (Oasis wound matrix, per square centimeter) as an add-on product layered to the wound bed. The primary procedure (for example, excisional debridement, closure, or grafting) is reported separately; Q4102 is billed in addition to that primary service. Documentation includes wound measurements, indication for use, procedures performed (debridement, irrigation), product lot number and quantity (cm2), consent, and post-application plan such as dressing type and follow-up. Typical sites of service are outpatient wound care clinics, physician office procedure rooms, and ambulatory surgical centers. Patients often require serial applications and follow-up visits for dressing changes and assessment of healing trajectory.
