Summary & Overview
CPT 63302: Thoracolumbar Vertebral Excision for Extradural Thoracic Lesion
CPT code 63302 represents a thoracolumbar surgical approach for partial or complete excision of the main body of a single vertebra to remove an extradural lesion in the thoracic spine. This code captures a complex, spine-directed resection that is typically performed by neurosurgeons or orthopedic spine surgeons in an operating room setting and has implications for clinical care pathways, perioperative resource use, and payer coverage policies nationally. Major national payers of interest include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn what the code denotes clinically, the typical site and service type, and where the procedure fits into spine surgery practice. The publication provides benchmarks and coding context relevant to this procedure, summarizes common payer considerations, and outlines clinical context for documentation and claim validation. Where specific input data is missing, the text notes that information is not available in the input. The focus is national in scope and intended for coding professionals, revenue cycle managers, and clinical leaders seeking concise, policy-oriented information about use of CPT code 63302.
Billing Code Overview
CPT code 63302 describes a surgical procedure using a thoracolumbar approach to perform a partial or complete excision of the main body of a single vertebra to remove an extradural lesion within the thoracic spine. The procedure involves resection of vertebral bone to access and remove pathology located outside the dura mater in the thoracic spinal region.
Service type: Surgical — spinal/orthopedic neurosurgery
Typical site of service: Inpatient or outpatient hospital operating room
Clinical & Coding Specifications
Clinical Context
A 58-year-old male presents with progressive thoracic back pain, unilateral lower-extremity radiculopathy, and new-onset gait instability. MRI of the thoracic spine demonstrates an extradurally located metastatic lesion centered in the T7 vertebral body with compression of the thecal sac and focal spinal cord compression. After multidisciplinary review, the patient is scheduled for a thoracolumbar approach partial corpectomy of a single thoracic vertebral body to decompress the spinal canal and obtain tissue for histopathology.
Preoperative workflow includes history and physical, consent discussing risks and benefits, preoperative imaging review (MRI and CT), anesthesia evaluation, and coordination with neurosurgery and orthopedic spine teams. Intraoperative care involves general endotracheal anesthesia, neuromonitoring (SSEP/MEP), posterior exposure via a thoracolumbar approach, partial or complete excision of the vertebral body to remove the extradural lesion, hemostasis, possible instrumentation or anterior column reconstruction as indicated, and specimen submission to pathology. Postoperative workflow includes ICU or PACU monitoring, pain control, early mobilization with physical therapy, and coordination of adjuvant oncology care if a metastatic lesion is confirmed.

| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required is substantially greater than typical for a partial or complete vertebrectomy due to extensive dissection, severe adhesions, or intraoperative complications that increase complexity. |
