Summary & Overview
CPT 70100: Mandible X‑ray, One to Three Views
CPT code 70100 represents plain radiographic imaging of the mandible, typically one to three views, used to evaluate suspected fractures and other osseous abnormalities of the lower jaw. As a fundamental diagnostic imaging service in maxillofacial care, this code is widely used in emergency, outpatient, and dental-related trauma settings nationally. Its utilization affects imaging workflow, resource allocation, and clinical decision-making for facial trauma and dental pathology.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a national overview of clinical context for 70100, common sites of service, and the typical role this radiograph plays in diagnostic pathways. The publication summarizes standard practice expectations, common billing modifiers (listed separately), and the typical clinical scenarios that generate this service.
This summary provides benchmarks for utilization and billing patterns where available, highlights relevant policy updates that affect imaging authorization and coverage, and clarifies the clinical utility of mandible radiographs versus alternative imaging modalities. Data not provided in the input are noted explicitly where applicable. The intent is to inform payers, providers, and billing professionals about the service profile and policy-relevant considerations surrounding CPT code 70100.

Clinical & Coding Specifications
Clinical Context
A patient presents to the emergency department after a fall during recreational sports with focal pain, swelling, and malocclusion of the lower jaw. The triage nurse documents facial trauma and the clinician performs a focused history and physical exam, noting tenderness along the mandibular body and pain with opening the mouth. The clinician orders diagnostic imaging to evaluate for mandibular fracture. A radiologic technologist performs a plain radiographic study of the mandible using 70100, obtaining one to three views (commonly panoramic, lateral oblique, and submental-vertex or PA views) as indicated by clinical findings. Images are reviewed by the interpreting clinician (emergency physician, oral/maxillofacial surgeon, or radiologist). Based on the radiographic findings, the patient is either discharged with oral/maxillofacial follow-up for conservative management or referred for operative fixation. Typical site of service is the emergency department, urgent care clinic, hospital radiology department, or outpatient imaging center.
