What 71100 covers
This service is a focused radiographic study of the ribs on one side, with images obtained in two views to assess localized pain, tenderness, suspected fracture, or another rib abnormality. It is commonly ordered after blunt chest-wall trauma or for focal rib symptoms and may be performed in an emergency department, hospital imaging department, or outpatient radiology office. A technologist acquires the images; a radiologist or other qualified physician interprets them.
Select 71100 when the study covers one side and includes two views. Documentation should support the side examined, the views obtained, the clinical reason, and the interpretation. If the images also include a chest view with unilateral ribs, compare 71101; bilateral rib studies are reported with different codes. CMS recognizes separately priced professional and technical components: modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff, and billing without either modifier represents the global service.

71100 billing questions
When should 71100 be chosen instead of 71101?
Use 71100 for two views of ribs on one side without a chest view included in the rib study. Compare 71101 when unilateral rib imaging includes a chest view.
How does 71100 differ from 71110?
71100 covers two views of ribs on one side. 71110 is the code to compare when both sides of the ribs are imaged.
Can the professional and technical portions be billed separately?
Yes. Modifier 26 identifies the interpretation, and modifier TC identifies the equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports 71100?
The record should identify the side examined, the two views obtained, the clinical indication, and the interpreting provider's findings.
Are units reported for each view?
No. Report the exam as one service rather than billing a separate unit for each image view.
