What 74177 covers

This study images the abdomen and pelvis, generally from the diaphragm through the pubic symphysis, during one combined examination. Diagnostic images are acquired after iodinated intravenous contrast, without a diagnostic precontrast series. Common indications include suspected appendicitis or diverticulitis, abscess, bowel obstruction, blunt trauma, and cancer staging or surveillance. Technologists perform the scan in hospital CT departments, emergency departments, and freestanding imaging centers; a radiologist interprets the images and issues a report.

Report one unit when both regions are imaged as a combined contrast-enhanced exam; do not substitute separate abdomen-only and pelvis-only CT codes. Documentation should identify the regions scanned, intravenous contrast administration, the series acquired, and the findings. On physician fee schedule claims, modifier 26 identifies the radiologist's interpretation and modifier TC identifies the equipment-and-staff portion. Report the global service without either modifier when the same billing entity provides both components. The diagnostic imaging multiple procedure reduction can affect both professional and technical components when another eligible imaging study, such as chest CT, is performed in the same session.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

74177 billing questions

Can CT abdomen with contrast and CT pelvis with contrast be billed separately when both are done in the same combined exam?

No. Report one unit of 74177 for the combined exam rather than 74160 plus 72193. The regional codes describe exams limited to their respective regions.

When should 74178 be used instead of 74177?

Use 74178 when a diagnostic noncontrast series is followed by contrast-enhanced imaging of the abdomen and pelvis. Use 74177 when the diagnostic acquisition is contrast-enhanced without a diagnostic precontrast series.

Does giving only oral contrast qualify the study as with contrast?

No. Oral contrast alone does not make this an intravenous contrast study; an abdomen and pelvis CT performed with oral contrast but without intravenous contrast is reported with 74176.

Which modifiers apply for split billing?

On physician fee schedule claims, the interpreting radiologist reports modifier 26 for the interpretation, while the provider billing for equipment and staff reports modifier TC. A billing entity that provides both components reports the global code without either modifier.

How is payment affected when CT chest is performed in the same session?

The diagnostic imaging multiple procedure reduction can affect the professional and technical components of eligible studies performed in the same session. A contrast-enhanced chest, abdomen, and pelvis staging exam may be reported with 71260 and 74177.

Do delayed images after intravenous contrast change the code to 74178?

No. Additional postcontrast images do not make the exam a without-and-with-contrast study; 74178 requires diagnostic imaging before contrast followed by contrast-enhanced imaging.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
