What 70310 covers
This code describes a limited intraoral dental radiographic examination consisting of two or three views, rather than a single view or a full-mouth series. It may be used when evaluating a localized concern such as tooth pain, suspected dental infection, or dental trauma. A dental professional typically obtains the images in a dental office or other outpatient setting; a qualified practitioner interprets them.
Report the code once for the two- or three-view examination, not separately for each image. Documentation should support the number of views and the teeth or area examined. The service has professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff portion, and billing without either modifier represents the global service. CMS separately prices the 26 and TC components.
