Radiology

About 74181: Abdominal MRI without contrast

Reports MRI imaging of the abdomen performed without contrast, such as evaluation of abdominal organs when the diagnostic protocol calls for noncontrast images.

This service covers magnetic resonance imaging of the abdomen using a protocol without contrast material. Radiologists interpret the images; imaging departments, hospitals, and independent diagnostic centers may furnish the technical service. Common clinical questions include assessment of abdominal organs such as the liver, pancreas, kidneys, or adrenal glands when noncontrast imaging is the requested protocol.

Select this code when the documented examination is limited to the abdomen and performed without contrast. The order and radiology report should support the body region and contrast protocol. Report the global service when one entity furnishes both the interpretation and imaging; use modifier 26 for the professional interpretation or TC for the technical service when those portions are billed separately. CMS applies the diagnostic imaging multiple procedure reduction to both professional and technical components when it applies to the reported services.

74181 billing questions

How does 74181 differ from 74182?

74181 is for abdominal MRI performed without contrast. Use 74182 when the abdominal MRI is performed with contrast.

When is 74183 reported instead?

74183 describes an abdominal MRI performed first without contrast and then with contrast. It is not the code for a noncontrast-only examination.

Can the professional interpretation and imaging be billed separately?

Yes. Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service; billing without either modifier represents the global service.

What documentation supports 74181?

The order and imaging report should identify the abdomen as the imaged region and support that the examination was performed without contrast.

Can multiple procedure reduction affect this code?

CMS diagnostic imaging multiple procedure reduction applies to the professional and technical components when multiple diagnostic imaging procedures are reported.

Should 74181 be used for an abdominal CT?

No. 74181 describes MRI. For an abdominal CT without contrast, consider 74150 when that modality and protocol match the service performed.
