Coding for MR angiography of the brain


If we perform magnetic resonance venography (MRV) of the brain with and without contrast (70546) and a Magnetic Resonance Arteriogram (MRA) of the brain without contrast (70544) at the same session, is appropriate append modifier 59 to CPT® code 70544?


The “A” in MRA is angiogram – not arteriogram and involves imaging of arteries, veins, or both. As such, you would code only 70546. The code and full description is as follows:

70546  Magnetic resonance angiography, head; without contrast material(s), followed by contrast material(s) and further sequences
