What 77002 covers
The service uses live x-ray imaging to guide a needle toward a target and confirm its position during a procedure. Radiologists, interventional radiologists, orthopedists, and pain physicians may use it for procedures such as joint aspiration or injection, or needle sampling of a lesion. The fluoroscopic guidance and its interpretation are distinct from the needle procedure itself.
Report 77002 only with a primary procedure; it is an add-on code and is paid within that procedure’s global period. The record should identify the target, document use of fluoroscopy to guide needle placement, and support the interpretation. Modifier 26 represents the professional interpretation, while modifier TC represents the equipment and staff. Reporting without either modifier represents the global service.

77002 billing questions
Can 77002 be reported by itself?
No. CMS identifies 77002 as an add-on code that must be billed with a primary procedure.
When is 77002 used with a joint injection?
It may be reported when fluoroscopy guides needle placement for a joint procedure, such as a large-joint aspiration or injection, and the guidance is separately reportable.
How does 77002 differ from 77003?
Both describe fluoroscopic needle guidance, but 77003 is for guidance in spinal or paraspinal procedures. Use 77002 for other needle-placement targets.
What do modifiers 26 and TC represent?
Modifier 26 identifies the professional interpretation; modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports 77002?
Document the needle target, the use of fluoroscopy to guide placement, and the interpretation. The claim must also include the primary procedure.
