Summary & Overview
CPT 22310: Closed Treatment of Vertebral Body Fracture with Immobilization
CPT code 22310 identifies closed treatment of a vertebral body fracture with application of a cast or brace for immobilization. As a procedural code for spine fracture management, it captures nonoperative, external immobilization techniques that can be provided across inpatient and outpatient settings. Nationally, accurate coding of spine fracture care matters for clinical outcome tracking, resource planning, and standardized payment for nonoperative fracture management.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical context for nonoperative vertebral fracture care, guidance on typical sites of service, and coverage considerations commonly encountered with commercial and federal payers. The publication summarizes reimbursement benchmarks and billing patterns where available, highlights common documentation elements supporting use of CPT code 22310, and outlines policy updates or payer rules that affect coverage and claim adjudication.
This summary is designed to give clinicians, coding professionals, and policy analysts a concise reference to the purpose and application of CPT code 22310, and what to expect in payer interactions for closed vertebral body fracture treatment with external immobilization.
Billing Code Overview
CPT code 22310 describes closed treatment of a fracture of the vertebral body with application of a cast or brace to immobilize the fracture during healing. This procedure addresses fractures of the main structural portion of a vertebra without open manipulation or internal fixation.
-
Service type: Closed fracture care with external immobilization
-
Typical site of service: Hospital inpatient or outpatient orthopedic/spine clinic, emergency department, or ambulatory surgical center when immobilization is performed as definitive or initial fracture management
Clinical & Coding Specifications
Clinical Context
A 68-year-old female presents to the emergency department after a ground-level fall with acute midline thoracic back pain and localized tenderness. Imaging (plain radiographs and CT) demonstrates a non-displaced compression fracture of a thoracic vertebral body without neurologic deficit or retropulsion. The orthopedic spine surgeon evaluates the patient, confirms stability of the fracture, and elects a closed treatment approach using external immobilization. The patient is fitted with a thoracolumbosacral orthosis (TLSO) or a rigid thoracic brace, provided instructions for activity restriction and pain control, and scheduled for outpatient follow-up with repeat imaging in 6 weeks to assess healing. Typical documentation includes history of present illness, fracture location and stability, neurologic exam, informed consent for closed management, procedure note documenting cast/brace application, and device description.
Typical site of service: Outpatient clinic, emergency department, or ambulatory surgery center for brace fitting and procedural application. Inpatient care may occur if comorbidities or inpatient admission are required.
