Radiology Question for the Week of December 28, 2015


How do I code for an MRI of the brain and MRI of the IACs?


The magnetic resonance imaging (MRI) of the internal auditory canals (IACs) is included with the brain MRI when the imaging is performed followed by only a few extra sequences. However, when a complete MRI of the brain study is performed in conjunction with a complete study of the IACs, it is appropriate to assign a brain MRI code twice and append the -59 modifier to second code.
