Use Code

## **What is HCPCS code A4565?** HCPCS Code A4565 represents slings used for arm or shoulder support to relieve pressure and promote healing following injuries or surgical procedures. It falls under the “Medical and Surgical Supplies – Various Supplies” category (A4450–A4608 range). These orthopedic products vary in size, weight, and material—often made from synthetic fabrics designed to support or immobilize an injured limb while maintaining comfort and stability. A4565 is considered a supply, not durable medical equipment (DME). Payment and coverage depend on the place of service and the Medicare contractor jurisdiction handling the claim. Providers must review, create, and complete all documentation before purchase or claim submission to ensure compliance with CMS and local coverage requirements.

## **HCPCS code A4565 documentation requirements** Documentation must verify that the sling was medically necessary and supplied appropriately. Providers and suppliers should include the following in the patient’s medical record: - The treating practitioner must issue a Standard Written Order (SWO) before claim submission. The SWO should list the beneficiary’s name, a detailed description of the item (A4565 – sling), quantity, and the ordering provider’s information, signature, and date. - Clinical documentation must support medical necessity, showing the condition being treated (for example, an upper-limb fracture, sprain, or post-surgical immobilization). - If the sling is delivered for home use, a Proof of Delivery (POD) record is required, including the patient’s name, delivery address, description of the item, quantity, and delivery date. Records must be retained for seven years in accordance with CMS documentation retention rules. - If billing as a supplier, ensure supplier enrollment and accreditation under Medicare supplier standards, including licensure, surety bond, and quality-standards compliance.

## **HCPCS code A4565 billing requirements** Billing for A4565 (Slings) should comply with current CMS and MAC guidelines: - The appropriate jurisdiction for A4565 is the Medicare Part B MAC, not the DME MAC. This split-jurisdiction rule has been in effect since July 1, 2001, and remains current. - Include the correct HCPCS code (A4565), quantity, and associated diagnosis code on the claim form. - Hospitals and outpatient facilities may report the item under a general medical/surgical supply revenue code (such as 027x), but it is typically packaged into the procedure payment under the Outpatient Prospective Payment System (OPPS) and not separately reimbursed. - If the sling is dispensed in a physician office or clinic, it can be billed to the Part B MAC when provided incident to care (e.g., fracture treatment or post-operative support). - Payment for A4565 is determined under the Medicare Physician Fee Schedule (MPFS) or the DMEPOS Fee Schedule, depending on the payer and local MAC rules. Always verify the latest allowable amounts on the current CMS fee schedule for your jurisdiction.
