What 74018 covers
A technologist obtains one projection of the abdomen, commonly a supine kidney-ureter-bladder (KUB) view, in an office, imaging center, emergency department, or at the bedside. Clinicians order it to evaluate bowel gas in suspected obstruction or ileus, locate radiopaque urinary stones or ingested objects, and check enteric tube position when the anatomy needed for confirmation is visible. A radiologist or other qualified interpreting physician reviews the images and documents findings. More than one exposure may be needed to cover the abdomen without creating another view.
Select 74018 by the number of abdominal projections, not the number of images or findings; document the projection obtained and its interpretation. Two abdominal views belong to 74019, three or more to 74021, and a complete acute abdomen series with chest imaging belongs to 74022. Medicare prices the interpretation separately with modifier 26 and the equipment and staff portion with modifier TC. Bill the combined service without a component modifier when the same billing entity provides both portions. For hospital imaging, the physician generally reports modifier 26; the facility reports its technical service.

- Count abdominal projections rather than exposures: one view is 74018; two views are 74019.
- 74021Abdominal X-ray
- Use 74021 for three or more abdominal views rather than the single view covered by 74018. A complete acute abdomen series with a chest view is reported with 74022.
- 74022Abdominal X-ray
- 74022 describes a complete acute abdomen series with multiple abdominal views and a chest view. A single abdominal view, with or without a separately ordered chest film, is not that series.
74018 billing questions
When should 74018 be reported instead of the two-view code?
Report 74018 for one abdominal projection. If a second projection, such as an upright or decubitus view, is obtained, use 74019 instead.
Which modifier does a radiologist interpreting a hospital film use?
The interpreting physician appends modifier 26 to report the interpretation and signed report. The hospital reports its technical service on the facility claim.
Can a single-view abdomen and a single-view chest be reported together?
When separately ordered and performed as distinct exams, report the one-view abdomen with 74018 and the one-view chest with 71045. A complete acute abdomen series with multiple abdominal views and a chest view is reported with 74022.
Do multiple images of the same abdominal projection count as multiple views?
No. If additional images extend coverage of the same projection, select 74018 based on the single view rather than the number of exposures.
How is the technical portion of a one-view abdominal study reported?
The entity furnishing the equipment and staff reports 74018 with modifier TC when billing only that portion. An entity furnishing both the technical service and interpretation reports 74018 without a component modifier.
