CT Perfusion

Date: Mar 21, 2014

Question:

At our institution, CTA brain and separate perfusion analysis with Diamox challenge is performed. We've referenced your 2014 Diagnostic Radiology Coding Reference, which states to code only non-contrast CT. We're performing CTA; how should we code the study? Can you explain to us why it is or is not appropriate to code 70496 and 0042T?
