What 70130 covers
This service is a plain-radiograph examination of the mastoid region, including the mastoid air cells behind the ears, with at least three views. It may be ordered when symptoms or examination findings raise concern for mastoiditis or other mastoid disease. A radiologic technologist typically obtains the images in a hospital imaging department, outpatient radiology center, or office with radiography equipment; a radiologist or other qualified physician interprets them.
Select this code when the documented mastoid examination includes at least three views; the fewer-view mastoid study is a different code. The order and report should identify the mastoid region examined and support the views obtained, including whether one or both sides were imaged. Medicare recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or neither modifier for the global service. When both sides are performed, CMS pays each side separately at 100%.

70130 billing questions
How does this differ from 70120?
70130 is for a complete mastoid examination with at least three views. Use 70120 for the mastoid examination with fewer views.
Can the interpretation be billed separately from the imaging?
Yes. Report modifier 26 for the professional interpretation and modifier TC for the technical service; without either modifier, the claim represents the global service.
How should bilateral mastoid imaging be reported?
When both sides are examined, report each side separately according to claim instructions. CMS pays each side at 100% when performed bilaterally.
Does the number of views affect code selection?
Yes. This code requires a complete examination with at least three views; a study with fewer views is represented by 70120.
What documentation supports 70130?
The record should support the clinical reason for the mastoid study, the region and side examined, and the complete examination with at least three views.
