Summary & Overview
HCPCS Level II A2019: Kerecis Omega3 Marigen Shield, Per cm
HCPCS Level II code A2019 designates the Kerecis omega3 marigen shield billed per square centimeter as an add-on wound care product reported in addition to a primary procedure. This code captures the use of a marine-derived, omega-3–enriched biologic dressing intended to protect and support healing of complex or hard-to-heal wounds. Nationally, accurate reporting of such product-level HCPCS codes matters for clinical documentation, supply cost tracking, and consistent reimbursement for advanced wound therapies.
Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical context and service settings, plus guidance on what to expect when benchmarking utilization and payment for add-on wound care products. The publication summarizes common billing modifiers applicable to add-on supply lines, typical sites of service where A2019 is used, and how this code fits into outpatient wound care service lines.
The report also outlines common policy considerations payers apply to biologic wound coverings, including requirements for linkage to a primary procedure, documentation of wound characteristics and prior conservative care, and reporting per-unit (per square centimeter) quantities. Data not available in the input is clearly noted where applicable.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with a chronic, nonhealing lower-extremity wound (for example, a diabetic foot ulcer or chronic venous leg ulcer) that has failed standard wound care such as debridement, offloading, moisture balance, and topical agents. After evaluation by a wound care specialist or podiatrist, the wound bed is debrided to healthy tissue, infection is controlled or addressed, and vascular status is optimized. During the same operative or procedure visit, a biologic skin substitute product, A2019 Kerecis omega3 marigen shield, is selected as an add-on per square centimeter to cover and protect the wound, promote granulation, and provide a scaffold for tissue regeneration. The product is measured and billed per square centimeter as an add-on to the primary wound procedure. Typical sites of service include outpatient wound care clinics, ambulatory surgery centers, hospital outpatient departments, and inpatient operating rooms when used as part of surgical wound management. The interdisciplinary workflow commonly involves the ordering clinician (wound care physician, podiatrist, or surgeon), nursing for wound measurement and preparation, procedural staff for application, and documentation of product type, quantity (cm2), wound measurements, debridement details, and any relevant modifiers for payer adjudication.
