Summary & Overview
CPT 22212: Thoracic Vertebral Osteotomy, Posterior or Posterolateral Approach
CPT code 22212 denotes a thoracic vertebral osteotomy performed through a posterior or posterolateral approach to realign the thoracic spine and correct spinal deformities. This code captures a complex orthopedic/neurosurgical procedure that can be central to treatment pathways for scoliosis, kyphosis, and other structural deformities. It matters nationally because spinal osteotomies carry substantial clinical risk, resource utilization, and variation in payer coverage and reimbursement across commercial and public plans.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, typical sites of service, and the kinds of benchmarks and policy factors that influence coverage and billing for major spine surgeries. The publication highlights common billing considerations, coding adjacency, and typical modifiers used with complex operative spinal procedures (listed separately), and outlines where readers can expect variation in prior authorization, bundling rules, and inpatient versus outpatient payment policies.
The report is designed for clinicians, coding professionals, and revenue managers seeking concise guidance on the clinical purpose of CPT code 22212, payer coverage landscape, and operational issues that affect reimbursement and claims adjudication for thoracic spinal osteotomy procedures nationwide.
Billing Code Overview
CPT code 22212 describes an osteotomy of a thoracic vertebra, a surgical bony incision performed on an upper-back vertebra to realign the spine and correct spinal deformity. The procedure is performed via a posterior or posterolateral approach, meaning the surgeon accesses the vertebra from the back or back-and-side of the patient.
Service type: Surgical — spinal osteotomy / corrective spine surgery
Typical site of service: Hospital operating room or specialized surgical center (inpatient or outpatient surgical setting depending on clinical circumstances)
Clinical & Coding Specifications
Clinical Context
A 52-year-old patient with progressive thoracic kyphoscoliosis and chronic mid-back pain refractory to conservative care is scheduled for a posterior thoracic vertebral osteotomy (CPT 22212) to correct spinal alignment. The preoperative workflow includes spine surgeon evaluation, imaging (standing scoliosis radiographs, CT for osseous detail, and MRI to assess neural elements), informed consent discussing risks (neurologic injury, blood loss, infection), medical clearance, and preadmission testing. On the day of surgery the patient is brought to the operating room, positioned prone on a radiolucent frame, and intraoperative neuromonitoring is initiated. The surgeon performs a posterior or posterolateral approach to the affected thoracic vertebra, carries out the controlled bony incision and wedge resection to mobilize and realign the segment, and may place instrumentation (pedicle screws and rods) and perform fusion as indicated. Postoperative care includes immediate neurologic assessment, pain control, wound care, activity restrictions, and outpatient follow-up with imaging to document alignment and fusion progress. Typical facility billing occurs on an inpatient or ambulatory surgery center claim depending on patient comorbidities and extent of correction. Payors commonly involved include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, BUCA, and Medicare.
