Summary & Overview
HCPCS A2029: Mirotract Wound Matrix Sheet, Per Cubic Centimeter
HCPCS Level II code A2029 represents the Mirotract wound matrix sheet, billed per cubic centimeter as an add-on supply in conjunction with a primary wound or reconstructive procedure. Nationally, this code matters because it standardizes reporting for an advanced biologic wound matrix used in surgical and outpatient wound-care settings, enabling clearer capture of material utilization and cost when applied to complex wounds or tissue reconstruction. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how A2029 is used in clinical billing, the typical sites of service where it appears, and what national billing considerations apply when adding an implantable or topical matrix to a primary procedure. The publication summarizes available benchmarks and payer coverage patterns where provided, highlights coding and billing context for add-on supply reporting, and outlines common modifiers associated with the service line. Data not available in the input is noted where applicable.
Billing Code Overview
HCPCS Level II code A2029 describes the Mirotract wound matrix sheet, billed per cubic centimeter. This entry is coded as an add-on, billed in addition to a primary procedure. The service type is wound care supply: biologic/dermal matrix material, intended for implantation or application to support wound closure and tissue repair. The typical site of service is outpatient wound care settings, ambulatory surgery centers, or hospital outpatient departments where advanced wound therapies and surgical reconstruction are performed.
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with a chronic full-thickness lower extremity wound after prior debridement presents for biologic graft placement. The wound measures 6 cm2 with exposed tendon but no overt infection. After appropriate wound bed preparation (sharp debridement, hemostasis, and irrigation) in an outpatient ambulatory surgical center, the clinician applies a Mirotract wound matrix sheet measured in cubic centimeters (A2029) as an adjunctive graft material to support tissue regeneration. The procedure is documented with the primary wound care or debridement procedure code (CPT code corresponding to the debridement or excision) and A2029 is billed as an add-on, per cubic centimeter, to reflect the volume of matrix placed. Typical workflow includes pre-procedure assessment, local or regional anesthesia, wound bed preparation, sizing and placement of the matrix, fixation as needed, wound dressing application, and post-procedure instructions with scheduled follow-up visits for dressing changes and graft assessment.
