Summary & Overview
CPT 63305: Transthoracic Excision of Thoracic Vertebral Body for Intradural Lesion
CPT code 63305 denotes a transthoracic surgical excision of the main body of a single thoracic vertebra performed to remove an intradural spinal lesion. This complex, invasive procedure is relevant nationally because it involves high-acuity inpatient care, substantial operative resources and specialized surgical expertise. It is typically performed in hospital operating rooms with postoperative inpatient management.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise overview of the clinical context for 63305, typical sites of service, and the service type tied to the code. The publication outlines common billing modifiers applicable to complex spinal procedures, summarizes typical payer coverage patterns where available, and highlights benchmarking and policy considerations relevant to hospitals and surgical departments.
This summary equips revenue cycle professionals, surgical program managers and clinical coders with the essential clinical and billing context for CPT code 63305, including how the code fits within thoracic spine operative care and what to expect in terms of service location and care intensity. Data not available in the input will be identified in detailed sections of the full publication.
Billing Code Overview
CPT code 63305 describes a surgical procedure in which the provider uses a transthoracic approach to perform a partial or complete excision of the main body of a single thoracic vertebra to remove an intradural lesion. This procedure targets one of the interlocking bones of the thoracic spine and is directed at excision of intradural pathology within the thoracic spinal canal.
-
Service type: Open thoracic spinal surgery for excision of intradural lesion involving partial or complete vertebral body removal.
-
Typical site of service: Inpatient hospital operating room, given the invasive transthoracic approach and spinal procedure complexity.
Clinical & Coding Specifications
Clinical Context
A 54-year-old patient presents with progressive mid-thoracic back pain, gait instability, and sensory deficits below the level of T6. MRI of the thoracic spine reveals an intradural extramedullary mass at T7 causing cord compression and myelopathy. After multidisciplinary review, the neurosurgery team schedules a transthoracic thoracic laminectomy/vertebrectomy and intradural tumor resection via transthoracic approach to remove the lesion. Preoperative workup includes cardiopulmonary clearance, thoracic CT for surgical planning, baseline neurologic exam, and informed consent discussing risks of neurologic deficit, pulmonary complications, and need for possible spinal stabilization.
On the day of surgery, the patient is placed in a lateral decubitus position for thoracotomy. A transthoracic approach is performed to access and perform a partial vertebrectomy of the involved thoracic vertebra, followed by intradural exposure, tumor excision, CSF management, and dural closure. Intraoperative neuromonitoring (somatosensory and motor evoked potentials) is used. Postoperative care includes ICU monitoring, chest tube management, pulmonary therapy, pain control, and early mobilization. Pathology confirms tumor type and subsequent adjuvant therapy is planned by oncology as indicated.
