## **What is the HCPCS code E2402 for?** The HCPCS code E2402 is under the category of Durable Medical Equipment (DME). This code specifically designates the provision and use of NPWT electrical pumps. A negative pressure wound therapy (NPWT) electric pump is often used to treat chronic wounds, traumatic wounds, pressure ulcers, deep tissue pressure injury, necrotic tissue, and surgically-created wounds with complications. Negative pressure wound therapy pumps, such as this one, apply controlled suction to a wound site via a dressing and tubing. It removes exudate and infectious materials from the wound. Doing so promotes wound healing and tissue granulation.

## **Documentation requirements for E2402** As with any HCPCS code, you'll need to prepare sufficient documentation that satisfies the correct coding guidelines and requirements set by your insurer, including any related policy articles and local coverage determinations. Here are examples of what you need: - The full name of the patient - The full names and credentials of the healthcare professionals handling the patient - The name, address, and type of facility where this pump was provided and used - Relevant information and indications related to the patient's medical record and current condition that justify medical necessity - Other justifications: wounds have not responded well to standard wound care; evidence of continued need for the pump - The pump must be capable of being selectively switched between continuous and intermittent modes of operation - The pump should have a controlled sub-atmospheric pressure that can be adjusted. The pump should be capable of maintaining sub-atmospheric pressure in the range of 40-80 mm Hg - The pump should have sensors and alarms to monitor pressure variations and exudate volume in the collection canister - Documentation of other treatments that have been tried and didn't work, or any other treatments they're currently undergoing (e.g., advanced moist wound therapy, comprehensive diabetic management program - Comprehensive details about the NPWT pump and supplies - Documentation of patient's response to treatment (e.g., progressive wound healing), dressing changes, ongoing wound care - Wound measurements (size, depth, duration)
