What 74263 covers

CT colonography screening uses computed tomography to produce images of the colon for evaluation for polyps or masses. The patient typically completes bowel preparation, and the colon is distended with gas to improve visualization. A radiologist interprets the reconstructed images. The service is performed in diagnostic imaging settings, such as a hospital or imaging center, for a colorectal cancer screening examination.

Report 74263 for the screening study; diagnostic CT colonography is represented by separate codes. Documentation should support the screening purpose and include the imaging study and interpretation. The global service is reported without a component modifier. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff. When the study is billed in components, the diagnostic imaging multiple procedure reduction applies to both the technical and professional components.

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.

74263 billing questions

How does 74263 differ from 74261?

74263 is for screening CT colonography. Use 74261 for a diagnostic CT colonography study without contrast.

When is 74262 used instead?

74262 represents diagnostic CT colonography with contrast. The screening purpose, rather than the imaging method alone, distinguishes 74263.

Which modifiers identify the components?

Append modifier 26 for the professional interpretation or modifier TC for the technical service. Report the global service without either modifier.

Does the multiple procedure reduction affect the components?

Yes. The diagnostic imaging multiple procedure reduction applies to the technical and professional components of this service.

What documentation supports reporting 74263?

Document the screening indication and the CT colonography performed, along with the interpreting radiologist’s findings. The record should make clear that the examination was for screening rather than diagnostic evaluation.

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.
