Summary & Overview
CPT 70210: Paranasal Sinus X‑ray for Sinusitis Assessment
CPT code 70210 represents a plain radiographic examination of the paranasal sinuses, commonly used to evaluate patients with suspected or known sinusitis. As a basic diagnostic imaging procedure, this code matters nationally because it is frequently used in outpatient and emergency settings to support clinical decisions about infection, obstruction, or complications of the sinuses. Imaging choices can affect downstream care, including antibiotic use, referral to specialists, and the need for further imaging.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for the code, typical sites of service, and the payer landscape relevant to coverage and claims processing. The publication summarizes common billing considerations and the clinical indications that drive use of 70210, and it describes available benchmarks and policy updates where provided.
The report is intended for billing managers, radiology departments, and policy analysts seeking a national perspective on the role of paranasal sinus radiography in sinusitis assessment, how major payers approach the service, and what operational and documentation elements are typically associated with use of CPT code 70210. Data not available in the input are identified where applicable.
Billing Code Overview
CPT code 70210 describes an X‑ray examination of the paranasal sinuses, performed for the assessment of sinusitis. The service involves radiographic imaging to evaluate the maxillary, frontal, ethmoid, and/or sphenoid sinuses to identify mucosal thickening, air‑fluid levels, opacification, or other anatomic findings consistent with sinus disease.
-
Service type: Diagnostic radiology — plain film X‑ray of the paranasal sinuses
-
Typical site of service: Outpatient radiology department, hospital radiology department, or freestanding imaging center

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting to an urgent care clinic or emergency department with several days of nasal congestion, facial pressure, purulent nasal discharge, and headache suspicious for acute sinusitis. The clinician performs a focused history and physical exam and documents localized tenderness over the maxillary and/or frontal sinuses and possible fever. When physical exam and history alone are insufficient to assess sinus opacification or complications (for example persistent symptoms despite initial therapy, concern for orbital involvement, or preoperative planning), the provider orders radiographic imaging of the paranasal sinuses. Radiology staff obtain standard sinus radiographs (e.g., Waters, Caldwell, lateral views) in the radiology suite or departmental x-ray room. The study is interpreted by the attending radiologist who provides a final report describing mucosal thickening, air-fluid levels, or sinus opacification. The facility bills for the technical component and the reading physician bills the professional component when applicable. Typical site of service is an outpatient radiology department, hospital radiology suite, urgent care clinic with radiography capability, or emergency department. Service type: diagnostic radiology — plain film imaging of the paranasal sinuses.
