Summary & Overview
CPT 63055: Transpedicular Repair of Thoracic Disc, Decompression
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. Readers will find clinical context for when the procedure is used, typical sites of service, and the common billing considerations associated with this surgical spine code. The publication outlines benchmarks and payment policy context where available, highlights coding relationships to related spine procedures, and summarizes common modifier usage patterns. Data not available in the input is noted when specific payer rates, ICD-10 pairings, and associated taxonomies are not provided.
Billing Code Overview
CPT code 63055 describes a transpedicular approach to repair a bulging thoracic intervertebral disc without manipulation of the spinal cord. The procedure accesses the disc through the side of the pedicle of a thoracic vertebra to relieve pressure on the spinal cord, cauda equina, or nerve roots.
-
Service type: Surgical decompression of the thoracic spine via a transpedicular approach
-
Typical site of service: Inpatient hospital or outpatient hospital operating room, depending on clinical need and complexity
Clinical & Coding Specifications
Clinical Context
A 54-year-old patient presents with progressive thoracic myelopathy and radicular pain refractory to conservative care, including physical therapy, oral anti-inflammatory medications, and epidural steroid injections. Imaging with MRI demonstrates a unilateral paramedian thoracic disc herniation causing focal spinal cord compression at the T7–T8 level without evidence of intradural tumor. The surgical team schedules a transpedicular thoracic discectomy and decompression to remove the offending disc fragment and relieve cord/nerve root pressure. The procedure is performed in an operating room under general anesthesia with neuromonitoring. The surgeon uses a transpedicular approach through the pedicle of the involved vertebra to access and remove the disc material without direct manipulation of the spinal cord. Typical perioperative workflow includes preoperative history and physical, informed consent, anesthesia evaluation, intraoperative fluoroscopy and neuromonitoring, possible placement of drains, postoperative recovery in the PACU, inpatient observation for neurologic monitoring, and a short course of discharge instructions with outpatient follow-up for wound check and neurologic assessment.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
62 | Two surgeons | Used when two surgeons from different specialties operate together, each performing distinct portions of the transpedicular decompression. |
80 | Assistant surgeon | Used when a qualified assistant surgeon provides intraoperative assistance. |
81 | Minimum assistant surgeon | Used when a minimal level of assistance is documented. |
82 | Assistant surgeon (unusual circumstances) | Used when a qualified resident or surgeon assists due to unusual circumstances and no assistant fee is payable. |
22 | Increased procedural services | Used when documentation supports substantially greater effort, time, or complexity than usual for the procedure. |
63 | Procedure performed on infants less than 4 kg | Rare for thoracic discectomy but used when performed on an infant meeting criteria. |
52 | Reduced services | Used when the surgery is partially reduced or not completed as originally planned. |
53 | Discontinued procedure | Used when the procedure is started but discontinued due to patient condition or intraoperative findings. |
59 | Distinct procedural service | Used when a separate, distinct procedure is performed on the same date that is not normally bundled with the transpedicular discectomy. |
26 | Professional component | Used when reporting only the physician’s professional component for a service that has a technical component (e.g., intraoperative neurophysiology interpretation billed separately when allowed). |
TC | Technical component | Used when reporting only the technical component of a service (e.g., monitoring equipment, technologist time) when billed separately. |
57 | Decision for surgery (not in provided list) | Data not available in the input. |
