CPT® Code 15940

The procedure described by CPT® Code 15940 involves the excision of an ischial pressure ulcer, which is a type of wound that occurs due to prolonged pressure on the skin, often seen in patients who are immobile. The ischial region refers to the area around the ischium, one of the three main bones that make up the pelvis, located at the lower part of the hip. In this surgical procedure, the physician typically positions the patient face down to access the ulcer effectively. An elliptical incision is made over the ischial tuberosity, which is the bony prominence of the ischium, allowing the surgeon to remove not only the ulcer itself but also any surrounding infected tissue. After excising the affected area, the wound is thoroughly irrigated to cleanse it of any debris or bacteria. The final step involves closing the wound with primary sutures, ensuring that the area is properly sealed to promote healing. It is important to note that if any bone beneath the ulcer is removed during the procedure, CPT® Code 15941 should be used instead, indicating a more extensive surgical intervention.
