Radiology
About 70120: Mastoid radiographs, fewer than three views
Reports a limited-view X-ray examination of the mastoid region, commonly used to assess mastoid air cells when the ordered study includes fewer than three views.
This code describes a limited-view plain radiographic examination focused on the mastoid region behind the ear, including the mastoid air cells. It may be ordered when a clinician is evaluating suspected mastoid disease, such as in a patient with ear symptoms or concern for mastoiditis. Radiologic technologists acquire the images, and a qualified physician interprets them. The service may be performed in an office imaging department or a hospital setting.
Select this code when the documented mastoid examination includes fewer than three views; use the related higher-view code when three or more views are obtained. The imaging report and technologist documentation should support the body site and number of views. CMS allows the professional interpretation to be billed with modifier 26 and the technical service with modifier TC; billing without either modifier represents the global service. For bilateral examinations, each side is paid separately at 100%, so the record should identify both sides studied.

70120 billing questions
When should I use 70120 instead of 70130?
Use 70120 for a mastoid radiographic examination with fewer than three views. Use 70130 when three or more views are obtained.
Can the interpretation and imaging service be billed separately?
Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service. Without either modifier, the claim represents the global service.
How is a bilateral mastoid examination handled?
CMS pays each side separately at 100% when both sides are examined. Documentation should identify the right and left sides.
What documentation supports reporting this code?
The imaging record should identify the mastoid region examined and show that fewer than three views were obtained. The interpretation should document the physician's findings.
Is a middle-ear X-ray the same service?
No. Code 70134 describes imaging focused on the middle ear, while 70120 is for the mastoid region. Select the code that matches the imaged anatomy and documented study.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
