The CPT® Code 20005 refers to the procedure of incision and drainage of a soft tissue abscess that is located subfascially, meaning it involves the soft tissue situated beneath the deep fascia. This procedure is typically performed when an abscess, which is a localized collection of pus, forms in the soft tissues of the body and requires surgical intervention to alleviate pain, prevent further infection, and promote healing. The process begins with making an incision over the area of the abscess, allowing access to the underlying tissue. The use of forceps or a closed blunt hemostat is essential for safely opening the incision and facilitating the drainage of purulent material, which is the thick fluid that accumulates in the abscess. During the procedure, specimens may be collected for culture and sensitivity testing, which helps in identifying the specific bacteria causing the infection and determining the most effective antibiotic treatment. Additionally, the surgeon will insert a finger through the incision to break up any pockets of pus, ensuring thorough evacuation of the abscess. The cavity is then irrigated with sterile saline to cleanse the area, and a drain may be placed or the cavity packed with gauze to promote further drainage and healing.
