Do all of the following qualify as CTA exams? We are verifying that Coronal, sagittal and/or axial MIP reformatted images meet the criteria for CT Angiograms. Our radiologist also stated they qualify as an angiogram because of its timing and thin 1mm reconstructions.

A.TECHNIQUE:
CT angiogram of the chest and abdomen performed with and
without IV contrast. Coronal and sagittal reconstructions were
created. Coronal MIP reformatted images were reviewed.

B.TECHNIQUE:
Noncontrast CT of the chest and abdomen followed by CTA of
the chest and abdomen with portal venous and delayed phases. 100 mL
Omnipaque 300 contrast was used. Sagittal and coronal reformatted
images were submitted.

C.TECHNIQUE:
57 cc Omnipaque 350 utilized. Multiplanar reconstructions were

performed of the chest. PE protocol was utilized. Coronal and axial MIPS

reformations were constructed.

In order to charge a CTA, a 3D technique must be done. Ex: MIP(maximum intensity projection), Volume Rendering, Maximum Intensity. Coronal, sagittal, and axial are 2D.

According to Clinical Examples in Radiology Fall 2007 they list these terms for 3D post-processing techniques that might be used in radiology documentation: maximum intensity projection (MIP), shaded surface rendering, volume rendering. Even if they are performing a CTA exam the documentation needs to support that code following the coding guidelines. If a report is missing a 3d technique I would ask for an addendum from the radiologist.

Your Examples:
A. MIP is mentioned
B. no mention of a 3d technique
C. MIPS mentioned
