Official Description

Application of halo, including removal, cranial, 6 or more pins placed, for thin skull osteology (eg, pediatric patients, hydrocephalus, osteogenesis imperfecta)

Common Language Description

The CPT® Code 20664 refers to the application of a cranial halo device, which is a specialized orthopedic apparatus designed to stabilize the cervical spine in patients with thin skull osteology. This procedure is particularly relevant for pediatric patients, as well as individuals suffering from conditions such as hydrocephalus or osteogenesis imperfecta, which can compromise the integrity of the skull and necessitate enhanced stabilization. The halo device is characterized by the use of six or more pins that are strategically placed to ensure secure attachment to the skull. The procedure begins with the preparation of the pin insertion sites, which involves shaving and cleansing the area with an anti-infective agent to minimize the risk of infection. Following this, a general anesthetic is administered to ensure the patient's comfort during the procedure. The halo is then carefully positioned over the skull, with specific attention given to the placement of the anterior, lateral, and posterior pins to avoid critical anatomical structures and ensure optimal stability. The removal of the halo device is also included in this code, highlighting the comprehensive nature of the procedure from application to removal.
