Get the Lowdown on MRA, MRI Differences

Question: Encounter notes indicate that the physician performed magnetic resonance angiography of the head. I must admit I don’t know much about MRAs — if that’s even an acronym! Can you tell me more about this test and how to code for it?

Answer: MRA is an acronym, and the test might also be referred to as magnetic resonance angiogram. You would choose from the following codes for head MRA, depending on encounter specifics:

  • 70544 (Magnetic resonance angiography, head; without contrast material(s))
  • 70545 (… with contrast material(s))
  • 70546 (… without contrast material(s), followed by contrast material(s) and further sequences)

Details: MRA is a noninvasive imaging technique that uses magnetic resonance imaging (MRI) to visualize blood vessels in the body. It provides detailed images of the blood vessels, allowing the provider to evaluate their structure and detect any abnormalities.
