Document that 3-D imaging was done:
When we bill for a CTA or MRA, we must document that 3-D images were created. Our macros must have a phrase such as:
"3-D Maximum Intensity Pixel (MIP) images were created and reviewed."
Document Administration of IV contrast:
We must also document the amount and type of contrast given, e.g.:
"100 ml of Isovue 300 was given IV." rate information may be useful, but is not required for billing purposes.
CTA and MRA reports must comply with MIPS/MACRA
All studies of the carotid (CTA, MRA, US) must describe the degree of stenosis using the distal carotid as a reference (as per the NASCET trial)
Studies must refer to the diameter of the distal (cervical) ICAs
e.g. if there is 76% stenosis of the right ICA:
Severe stenosis of the right ICA.
Note:
Internal carotid artery stenosis reported are based on the distal internal carotid artery as a reference as used in the 1998 NASCET study.
Mild stenosis <50 %
Moderate stenosis 50-69 %
Severe stenosis 70-99 %
