What 70220 covers
70220 represents a complete plain-radiograph examination of the paranasal sinuses, using at least three views to assess the sinus cavities. The study may be performed in an office imaging suite or hospital radiology department by radiologic technologists, with images interpreted by a radiologist or another qualified physician. The order and report should identify the paranasal sinuses as the imaged anatomy, rather than the orbits, skull, or sellar region.
Select 70220 when the documentation supports a complete sinus series with at least three views, rather than a limited sinus study. Retain the order, images, and interpretation or report to support the service. CMS separately prices the professional and technical components: report modifier 26 for interpretation alone, modifier TC for the equipment and staff portion alone, or no component modifier when billing the global service. When different entities furnish the components, each reports its respective portion.

70220 billing questions
How does 70220 differ from 70210?
70220 is for a complete sinus series with at least three views. Use 70210 for a limited sinus examination with fewer views.
Which modifiers identify the components?
Use modifier 26 for the professional interpretation and modifier TC for the technical portion. Billing without either component modifier represents the global service.
What documentation supports 70220?
The record should identify a paranasal sinus examination and support a complete series of at least three views. Keep the order, images, and interpretation or report.
Can 70220 be reported for orbital or skull views?
No. The documented target must be the paranasal sinuses; orbital and skull examinations describe different anatomy.
When might CT be selected instead?
A clinician may select maxillofacial CT when cross-sectional imaging is needed for the sinus evaluation. Report the CT code that matches the documented contrast protocol, not 70220 for that CT study.
