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 wound healing process 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, all of which are critical factors in the healing process. The dressing used in NPWT typically consists of a foam or gauze filler material that is shaped to fit the contours of the wound. This filler is then covered with a transparent bio-occlusive film that maintains the necessary environment for healing. A drainage tube is inserted into the wound through a small slit in the film, allowing for the continuous removal of exudate and other fluids. 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. During each dressing change, the wound is assessed for signs of healing and infection. If necessary, the wound may be irrigated and cleaned, and topical medications can be applied to further support the healing process. After the wound is redressed, the patient or caregiver receives detailed instructions for ongoing care to ensure proper management of the wound outside of clinical settings. It is important to note that CPT® Code 97607 is specifically utilized for cases where the total surface area of the wound(s) is less than or equal to 50 square centimeters, while CPT® Code 97608 is designated for larger wound areas. The equipment used in NPWT is classified as non-durable, meaning it is typically single-use and disposable, allowing for a portable and mobile treatment option for patients.
