CPT^® 20664, Under General Introduction or Removal Procedures on the Musculoskeletal System

Summary

Providers apply a cranial halo to correct a deformity or injury to the cervical spine in a patient with an abnormal skull shape. The procedure requires the use of six more pins to secure the halo ring with significantly less force applied to the pins to avoid damage to the skull or nervous system. The patient also wears a vest that attaches to the halo for further stabilization.

Pediatric patients with abnormal skull shapes benefit from this procedure. Disorders such as hydrocephalus, a fluid accumulation in the brain, or osteogenesis imperfecta, a bone formation disorder that results in brittle bones, result in abnormal skull shapes.

This service also includes removal of the halo.
