Summary & Overview
HCPCS Q4440: Curamatrix Per Square Centimeter, Add-On
HCPCS Level II code Q4440 designates Curamatrix billed per square centimeter as an add-on item to be reported in addition to a primary wound procedure. This product-specific code is used when a biologic matrix is applied to a wound site and is priced by surface area rather than as a standalone procedure, affecting billing workflows where adjunctive wound products are used. Nationally, add-on HCPCS codes for advanced wound products matter because they influence reimbursement for complex wound care, documentation requirements, and utilization tracking for expensive biologic materials.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise national overview of what the code represents, payer coverage context, billing considerations tied to add-on product reporting, and where this code typically appears on the service line. The publication provides benchmarks for how adjunctive biologic matrix codes are treated by major payers, notes common clinical settings and service types for application, and summarizes gaps where data were not provided. Data not available in the input are noted where applicable.
Billing Code Overview

Clinical & Coding Specifications
Clinical Context
A patient with a chronic or complex wound (for example, a non-healing diabetic foot ulcer, venous stasis ulcer, or full-thickness surgical wound) presents to an outpatient wound care clinic or hospital outpatient department. The wound has been debrided and assessed; the treating clinician determines adjunctive biologic matrix placement will aid granulation and closure. Q4440 (Curamatrix, per square centimeter) is billed as an add-on supply code in addition to the primary wound repair or debridement procedure. Typical workflow: wound assessment and documentation of size and depth; procedural debridement and irrigation; measurement of wound area; selection and preparation of the Curamatrix product sized to the wound; placement of the biologic matrix; application of appropriate dressings; and documentation of product type, quantity in square centimeters, lot number, and clinical indication. The typical site of service is an outpatient wound care clinic, ambulatory surgery center, or hospital outpatient department. The typical patient scenario includes adult patients with impaired healing due to diabetes, venous insufficiency, prior radiation, or ischemia, where an extracellular matrix product is used to support tissue regeneration and closure.
