Summary & Overview
CPT 70110: Mandible X-Ray, Four or More Views
CPT code 70110 covers plain radiographic imaging of the mandible with four or more views, performed to diagnose fractures, other abnormalities, or to confirm reduction of a fracture. As a targeted diagnostic X‑ray, this code is used across acute and outpatient settings where facial trauma or jaw pathology is evaluated. Nationally, accurate coding of mandible radiographs affects clinical workflow, imaging utilization patterns, and appropriate billing for radiology services.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for mandible radiography, the typical sites of service where 70110 is used, and the payer landscape relevant to reimbursement and coverage determinations. The publication highlights common billing modifiers and coding considerations where available and summarizes how payers commonly categorize and reimburse plain mandible X‑rays.
This analysis is intended to help billing managers, radiology coders, and policy staff understand the role of CPT code 70110 in diagnostic imaging workflows, what to expect from major payers, and which operational and documentation elements are commonly relevant when this service is billed. Data not available in the input are explicitly omitted.
Billing Code Overview
CPT code 70110 describes plain radiographic imaging of the mandible (lower jaw) with four or more views obtained as needed to diagnose fractures or other abnormalities, or to confirm reduction of a fracture. This service is an imaging procedure focused on evaluation of the mandible.
Service Type: Plain radiography (diagnostic X-ray) of the mandible
Typical Site of Service: Hospital radiology department, emergency department, or outpatient imaging center
Clinical & Coding Specifications
Clinical Context
A patient presents to the emergency department after a direct blow to the lower face during an altercation. The patient reports acute jaw pain, malocclusion, difficulty opening the mouth, and localized swelling. Vital signs are stable. The treating clinician performs a focused maxillofacial exam and documents point tenderness over the mandibular body and chin, step-off on palpation, and possible tooth mobility. To evaluate for mandibular fracture and to plan reduction or operative repair, the provider orders plain radiographs of the mandible obtaining at least four views (e.g., panoramic or combination of AP, bilateral oblique, and mandibular Town or occlusal views) per CPT 70110. Imaging is performed in the radiology suite or emergency department radiography room. The interpreting provider documents findings to confirm presence, location, displacement, and to assess post-reduction alignment when applicable. Typical workflow includes triage, clinical exam, image acquisition by radiologic technologist, provider interpretation and documentation, and integration of imaging results into the treatment plan (conservative management, closed reduction, or operative fixation).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | When reporting only the physician interpretation separate from technical component |
TC | Technical component | When reporting only the technical portion (equipment/technologist) of the radiograph |
59 | Distinct procedural service | When another distinct service or imaging study is performed at the same visit and needs separate reporting |
76 | Repeat procedure by same physician | When the same provider repeats the radiographic procedure later the same day |
77 | Repeat procedure by another physician or technologist | When a repeat radiograph is performed by a different provider/technologist |
52 | Reduced services | When fewer views or partial service is provided compared with full CPT 70110 requirements |
53 | Discontinued procedure | When the imaging procedure is started but stopped due to patient condition |
90 | Reference (outside) laboratory or service — not listed in provided modifiers but commonly used | Data not available in the input. |
Q6 | Service furnished at off-campus outpatient provider-based department of a hospital | When the imaging is performed at an off-campus hospital outpatient department |
| Taxonomy Code | Specialty | Notes |

207P00000X | Emergency Medicine | Often orders and reviews radiographs for acute facial trauma in ED |
207Q00000X | Family Medicine | May evaluate facial injury and order imaging in urgent care settings |
261QM0800X | Radiology - Diagnostic | Performs radiographic imaging and provides official interpretations |
