What 74021 covers
This service is an abdominal X-ray examination using three or more views to show the distribution of bowel gas and other radiopaque findings. It may be ordered for abdominal pain or suspected ileus or bowel obstruction, and can help evaluate a radiopaque foreign body. Radiologic technologists acquire the images; a physician, commonly a radiologist, interprets the study. It is performed in settings such as hospital imaging departments and outpatient radiology centers.
Select this code when the documented abdominal study includes at least three views; the number and types of views should support that selection. Report the study once rather than billing separately for each image. Documentation should identify the views obtained and support the clinical reason for imaging. CMS recognizes professional and technical components: modifier 26 represents the interpretation, modifier TC represents equipment and staff, and billing without either modifier represents the global service.

74021 billing questions
Does each abdominal view generate a separate unit?
No. Report the radiographic study, not a separate unit for every image; the record should support the number and types of views.
How are the professional and technical portions billed?
Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
How does 74021 differ from an acute abdomen series?
74021 represents an abdominal study with at least three views. The acute abdomen series code, 74022, includes chest imaging as part of the series.
What documentation supports reporting 74021?
The imaging record should identify at least three abdominal views, and the report should document the findings and interpretation. The order or clinical record should support the reason for the examination.
