CPT® Code 30915

The procedure described by CPT® Code 30915 involves the ligation of the ethmoidal arteries, which are critical blood vessels located in the nasal region. This surgical intervention is primarily performed to manage severe epistaxis, commonly known as a nosebleed, that cannot be effectively controlled through less invasive methods. The ligation process entails a careful surgical approach, typically initiated through an incision made between the inner canthus of the eye and the midline of the nose. This precise location allows the physician to access the ethmoidal arteries directly. During the procedure, the periosteum, which is the connective tissue that covers the bones, is incised and elevated to expose the underlying structures. The surgeon identifies the suture line between the ethmoid and frontal bones at the superior aspect of the lacrimal bone, which is crucial for navigating the surgical field. Following this, the periosteum is further elevated off the medial wall of the orbit along the identified suture line. The anterior and posterior ethmoid arteries are then located and ligated using sutures or vascular clips, effectively reducing blood flow to the area and addressing the source of the bleeding. This procedure is essential for patients experiencing uncontrollable nosebleeds, providing a definitive solution when other treatment options have failed.
