Summary & Overview
CPT 63078: Thoracic Discectomy with Interbody Grafting
CPT code 63078 designates an add-on thoracic discectomy procedure in which a surgeon repairs an additional herniated thoracic disc and places interbody graft material to restore disc space. It is used when multiple thoracic levels require decompression during the same operative session and is billed in conjunction with a primary thoracic discectomy code. The code matters nationally because thoracic disc herniations, while less common than cervical or lumbar herniations, can cause significant pain, radicular symptoms, or myelopathy that necessitate surgical decompression and reconstruction.
Key payers commonly involved in coverage decisions include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context about the procedure and typical sites of service, as well as a concise framework for interpreting how this add-on code fits into operative reporting. The publication provides benchmarks and coding relationships relevant to surgical spine service lines, highlights common billing and documentation considerations, and summarizes where to find authoritative guidance for coding and reimbursement. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 63078 is an add-on thoracic discectomy with interbody grafting performed to repair an additional herniated thoracic intervertebral disc during the same operative session. The procedure decompresses affected nerve roots or the spinal cord by removing all or part of the herniated disc and uses graft material to fill the disc space created by removal.
Service type: Surgical — thoracic spine decompression with interbody grafting
Typical site of service: Inpatient or outpatient hospital operating room or ambulatory surgery center, depending on clinical severity and facility capabilities.
Clinical & Coding Specifications
Clinical Context
A 54-year-old patient presents with progressive thoracic radicular pain and gait instability over several months. Imaging with MRI identifies a symptomatic herniated thoracic intervertebral disc impinging on the spinal cord and adjacent nerve roots at T7–T8 with associated cord compression and edema. Conservative measures including physical therapy, analgesics, and epidural steroid injection provided insufficient relief. The neurosurgeon schedules a thoracic discectomy with decompression and placement of an interbody graft to restore disc height and stabilize the segment. The procedure is performed in an operating room under general anesthesia with intraoperative neuromonitoring. The surgeon removes the offending disc material, decompresses the spinal cord and nerve roots, and places an appropriate graft to fill the defect. Typical perioperative workflow includes preoperative imaging review, informed consent, anesthesia evaluation, positioning (prone), intraoperative fluoroscopy, possible instrumentation if indicated, immediate postoperative neurological assessment, and a brief inpatient observation for pain control and monitoring for potential complications such as cerebrospinal fluid leak or new neurologic deficit. Billing uses the add-on code 63078 appended to the primary thoracic decompression/discectomy service when an additional herniated thoracic disc is repaired during the same operative session.
