CPT® Code 97606

Negative pressure wound therapy (eg, vacuum assisted drainage collection), utilizing durable medical equipment (DME), including topical application(s), wound assessment, and instruction(s) 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 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 environment while simultaneously protecting the wound from external contaminants. The application of negative pressure serves multiple purposes: it helps to remove excess fluid from the wound area, reduces edema, and increases blood circulation to the site, all of which are critical factors in the healing process. The dressing used in NPWT typically consists of a cell foam or gauze filler material that is specifically shaped to fit the contours of the wound. This filler is then covered with a transparent bio-occlusive film that maintains the integrity of the sealed environment. A drainage tube is inserted into the wound through a small slit in the film, allowing for the connection to the vacuum pump. 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 and infection, and may involve irrigation and cleaning of the wound, as well as the application of topical medications. After the wound is redressed, the patient or caregiver receives detailed instructions for ongoing care to ensure proper management of the wound and to promote optimal healing outcomes. It is important to note that CPT® Code 97606 is specifically utilized when the total surface area of the wound(s) exceeds 50 square centimeters, distinguishing it from CPT® Code 97605, which is applicable for wounds measuring 50 square centimeters or less.
