What 73115 covers
This service covers radiographic imaging of the wrist joint after contrast has been introduced into the joint, with radiologic supervision and interpretation. It is used when a clinician needs to evaluate wrist joint structures, such as in an arthrographic workup of suspected internal derangement. A radiologist typically interprets the study; the technical work involves the imaging equipment and staff in an outpatient imaging department or hospital radiology department.
Select this code for the radiographic arthrography study, rather than a routine wrist radiograph. The record should support the wrist studied, contrast arthrography, and the interpreting physician’s findings. CMS recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or no component modifier for the global service. For bilateral studies, CMS pays each side separately at 100%; documentation should identify both wrists.

How to choose
- 73100Wrist X-rayTwo views
- 73100 reports routine wrist radiographs rather than contrast arthrography. Choose it when standard wrist views, not a contrast joint study, are obtained.
- 73110Wrist X-rayComplete, minimum three views
- 73110 is for routine wrist radiographs. 73115 applies when the wrist is imaged as a contrast arthrography study.
- 25246Wrist injectionArthrography
- 25246 describes the wrist joint injection for arthrography; 73115 describes the radiographic imaging and interpretation.
73115 billing questions
When should this be used instead of a routine wrist X-ray?
Use 73115 for contrast-enhanced arthrographic imaging of the wrist joint. Routine wrist views without arthrography are reported with an appropriate plain-radiograph code, such as 73100 or 73110.
Can the wrist joint injection be billed separately?
Code 73115 reports the radiographic arthrography imaging and interpretation. When a separate wrist arthrography injection is performed and reportable, code 25246 describes that injection service.
How are the professional and technical services reported?
Use modifier 26 for the professional interpretation and modifier TC for the technical service. Without either component modifier, the claim represents the global service.
How should bilateral wrist arthrography be reported?
Identify each wrist separately in the documentation and report each side. CMS pays each side separately at 100% when the study is bilateral.
What documentation supports 73115?
Document the wrist examined, that the study used contrast arthrography, and the radiologist’s interpretation. For bilateral imaging, specify both sides.
