Summary & Overview
HCPCS Q4424: Revive per Square Centimeter, Add-on Supply
HCPCS Level II code Q4424 designates the per-square-centimeter billing for Revive foam as an add-on supply used in wound and skin care procedures. As an add-on product code, Q4424 is billed in addition to a primary procedure and documents surface-area–based use of the Revive product. Nationally, area-based supply codes like Q4424 are important for precise reporting of consumable wound-care products and for aligning payment with actual product utilization.
Key payers in typical coverage discussions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the code’s clinical context, typical sites of service, and how the code functions as an add-on supply line. The publication also outlines expected benchmarks and policy considerations relevant to national payers, and highlights where clinical documentation should support square-centimeter measurement when billing.
This summary is intended to help billing staff, clinicians, and policy analysts understand the role of HCPCS Level II code Q4424 in documenting and reporting Revive product use alongside primary wound procedures, and what elements are commonly reviewed by payers during coverage and claims adjudication.

Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an outpatient wound care clinic or a hospital outpatient department treating a patient with a chronic or complex skin wound requiring topical biotherapeutic application. The service described by Q4424 (Revive ft, per square centimeter) is an add-on, per-square-centimeter supply code used when a proprietary topical regenerative or biologic dressing product is applied in addition to a primary wound debridement or reconstruction procedure. A representative workflow: the patient arrives for evaluation of a non-healing lower extremity ulcer. The clinician documents wound size and etiology, performs wound cleansing and selective sharp debridement (or directs a surgical debridement in the operating room), measures the wound surface area, and applies the specified topical product measured in square centimeters. Photographs and measurements are recorded in the medical record. The primary procedure (for example, a debridement or skin graft) is reported with the appropriate CPT code, and Q4424 is reported as an add-on supply code to bill the per-square-centimeter product used. Typical sites of service include outpatient wound care centers, hospital outpatient departments, ambulatory surgery centers, and skilled nursing facilities when wound treatment is rendered at the bedside. Typical patients are adults with diabetic foot ulcers, venous stasis ulcers, pressure injuries, or post-surgical graft recipient sites requiring advanced biologic topical therapy to promote healing.
