Dedicated HCPCS Billing Code for Arch Therapeutics’ AC5® Advanced Wound System Now In Effect

New code is expected to advance commercialization efforts in doctors’ offices and other outpatient settings

FRAMINGHAM, Mass., April 05, 2023 (GLOBE NEWSWIRE) -- Arch Therapeutics, Inc. (OTCQB: ARTH) (“Arch” or the “Company”), a marketer and developer of novel self-assembling wound care and biosurgical products, today announced that the Centers for Medicare and Medicaid Services (“CMS”) Level II Healthcare Common Procedure Coding System (“HCPCS”) code dedicated to the Company’s AC5® Advanced Wound System (“AC5”) went into effect on April 1, 2023.

The HCPCS code, A2020, establishes a new pathway for the reimbursement of AC5 and is expected to improve the ability of providers in outpatient facilities, including doctors’ offices, wound care clinics, hospital outpatient departments and ambulatory surgical centers, to seek payment from CMS and commercial payor networks throughout the country for use of the product.

Dan Yrigoyen, Vice President of Sales of Arch Therapeutics, said, “Since the announcement last month that CMS created a HCPCS code for AC5 Advanced Wound System, we have had new product inquiries by potential customers in offices and other outpatient facilities who previously indicated they were unwilling to order AC5 absent an available dedicated reimbursement code. We believe that A2020 will facilitate new and ongoing engagement with a growing number of interested potential customers in outpatient settings.”

AC5 was cleared as a medical device by the Food and Drug Administration (“FDA”) for the management of partial and full-thickness wounds, such as pressure sores, leg ulcers, diabetic ulcers, and surgical wounds.

“This now-effective AC5-specific code represents an essential element of our ongoing commercialization plan that we believe will help drive continued adoption and use of AC5 and increase opportunities to provide patients with improved outcomes for wound healing. While a code does not guarantee coverage or payment, its effectiveness marks a key commercialization milestone for the Company,” concluded Mr. Yrigoyen.

AC5 is a proprietary synthetic self-assembling wound care product designed to provide clinicians with multi-modal support and utility across all phases of wound healing. Once applied, AC5 conforms to a wound’s peaks and valleys prior to automatically assembling, thereby providing a different approach to manage challenging, irregular, undermined, and tunneling wounds. Case studies demonstrating that the use of AC5 can lead to improved outcomes, including limb salvage (avoided limb loss), even for patients who have not responded to alternative modalities, may be found here:
