What 70100 covers
This service covers radiographic imaging focused on the mandible, commonly obtained after jaw trauma or for focal pain or suspected fracture. A radiologic technologist typically acquires the images in an imaging department, hospital, or office; a qualified interpreting practitioner reviews them and prepares the diagnostic report. The study must include fewer than four views of the mandible.
Select this code based on the documented anatomy and view count, rather than the reason for imaging alone. The order, image record, and interpretation should support a mandibular study and the number of views performed. CMS recognizes separately priced professional and technical components: modifier 26 identifies the interpretation, and modifier TC identifies equipment and staff. Without either modifier, the claim represents the global service, including both components.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

70100 billing questions

What do modifiers 26 and TC represent?

What does billing the code without a modifier represent?
An unmodified claim represents the global service, with both the technical and professional components.
What documentation supports reporting this code?
The record should identify the mandible as the imaged anatomy and support the number of views performed. The interpreting practitioner’s report supports the professional component.
Is a panoramic dental image the same service?
No. A panoramic survey of the maxilla and mandible is reported with 70355; this code describes a mandible study with fewer than four views.
