Summary & Overview
CPT 72070: Thoracic Spine X‑Ray, AP and Lateral
CPT code 72070 denotes a diagnostic radiographic examination of the thoracic spine, generally consisting of AP and lateral projections to image the twelve thoracic vertebrae. This basic radiographic study is a common frontline imaging tool used to assess fractures, dislocations, bone disease, osteoporosis, and spinal curvature abnormalities. Nationally, thoracic spine radiography remains an essential and widely used service across emergency departments, outpatient imaging centers, and hospital radiology suites because of its accessibility, low radiation exposure relative to advanced imaging, and utility in initial clinical evaluation.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical purpose and typical delivery settings for the service, plus the payer landscape covered in the analysis. The publication also outlines common billing modifiers and comparative billing considerations, contextualizes the code within routine diagnostic workflows, and highlights what to expect in terms of administrative processing and clinical indications.
This summary is intended for a national audience of health policy analysts, billing professionals, and clinical managers seeking a clear reference on the clinical role, typical sites of service, and payer coverage environment for CPT code 72070.
Billing Code Overview
CPT code 72070 describes a radiologic examination of the thoracic spine, typically performed with anteroposterior (AP) and lateral projections. The study images the twelve thoracic vertebrae to evaluate bone injuries, fractures, dislocations, osteoporosis, and spinal deformities.
Service type: Diagnostic radiology — plain radiography of the thoracic spine
Typical site of service: Outpatient radiology department, hospital radiology, or ambulatory imaging center
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient presents to the outpatient radiology suite after a primary care visit for mid‑thoracic back pain following a ground‑level fall two days earlier. The clinician documents localized tenderness over the thoracic spine and limited range of motion; concern is raised for a compression fracture or acute vertebral injury. The patient arrives at the imaging center, registration confirms identity and insurance (Blue Cross Blue Shield, Aetna, Cigna Health, UnitedHealthcare, BUCA, Medicare), and the technologist reviews contraindications and pregnancy status. The technologist performs a standard two‑view radiographic study of the thoracic spine — an anteroposterior (AP) and lateral projection — using radiation‑sparing techniques and proper collimation. Images are reviewed for adequacy; additional projections (oblique or swimmer’s view) may be obtained if requested by the interpreting radiologist. The radiologist generates a report documenting alignment, vertebral body heights, evidence of acute fracture, degenerative change, and any compressive deformity. The final report is transmitted to the ordering provider for clinical management decisions such as bracing, further cross‑sectional imaging, or orthopedic referral.
