CPT code 63055 covers a surgical transpedicular repair of a bulging thoracic disc performed without manipulation of the spinal cord. This targeted decompression approach relieves pressure on the spinal cord, cauda equina, or nerve roots by accessing the disc through the pedicle of a thoracic vertebra. The code is relevant nationally as thoracic disc disease, while less common than cervical or lumbar disease, can produce significant myelopathic or radicular symptoms that require operative management.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
