CPT® Code 97608

Negative pressure wound therapy, (eg, vacuum assisted drainage collection), utilizing disposable, non-durable medical equipment including provision of exudate management collection system, topical application(s), wound assessment, and instructions for ongoing care, per session; total wound(s) surface area greater than 50 square centimeters

Negative pressure wound therapy (NPWT) is a specialized treatment method designed to facilitate the healing process of both acute and chronic wounds, as well as to enhance the recovery of first- and second-degree burns. This therapy involves the controlled application of sub-atmospheric pressure, which can be administered either intermittently or continuously, to a localized area of the wound. The wound is first sealed with a bio-occlusive dressing that is connected to a vacuum pump, creating a sealed environment that promotes a moist healing atmosphere while simultaneously protecting the wound from external contaminants. The NPWT system typically utilizes a dressing made from cell foam or gauze, which is tailored to fit the contours of the wound. This dressing is then covered with a transparent bio-occlusive film to maintain the integrity of the sealed environment. The vacuum pump plays a crucial role in this therapy by removing excess fluid from the wound area, which helps to reduce edema and promotes increased blood circulation to the site. This enhanced blood flow is vital for delivering necessary nutrients and oxygen to the wound, thereby supporting the healing process. The dressing is generally changed two to three times per week, during which the old dressing material and drainage tubing are disposed of in biohazard bags to ensure safety and compliance with health regulations. Each dressing change includes a thorough assessment of the wound for signs of healing or infection, and may involve irrigation and cleaning of the wound, as well as the application of topical medications. After the wound is redressed, patients or caregivers receive detailed instructions for ongoing care to ensure proper management of the wound. It is important to note that CPT® Code 97608 is specifically designated for cases where the total surface area of the wound(s) exceeds 50 square centimeters, distinguishing it from CPT® Code 97607, which applies to smaller wound areas.
