Compliance Question of the Week – Radiology

I have been assigning the following codes for contrast-enhanced liver ultrasound:
76705       Ultrasound, abdominal, real time with image documentation; limited (e.g., single organ, quadrant, follow-up)
Q9950      Injection, perflexane lipid microspheres, per ml
However, I was just told that I should be reporting C9744 (ultrasound, abdominal, with contrast) instead. Is this correct?

May I report MRI and MRA of the brain during the same session?

What key words need to be in the radiology report to assign a CTA code?

If a different physician or physician group is doing the nuclear medicine study on the same day, can an interventional radiologist bill anything for the injection of MAA [technetium tc-99m macroaggregated albumin]?

In the 2/13/17 question you said 77063 could be billed with G0202 because it was digital and not with 77067 because it was analog. Those descriptions are no longer part of the code. I have been told by multiple sources to use CPT 77063 for ALL screening mammograms except Medicare which is the G0202 until 2018. Is this not correct?

Can CPT code 77063 be reported with 77067?

Can you tell me the codes for the MRI contrast materials ProHance and MultiHance?

When will CMS implement its appropriate use criteria (AUC)?

When will CMS start accepting the new mammography codes?

How do we bill out a myocardial perfusion scan that is performed over a two-day period? Does it get billed out on the date it is started or on the day it is finished?

A physician ordered a neck computed tomography (CT) for indication of a palpable neck mass. A few CT images were obtained without contrast with a lead BB (opaque marker) to mark the mass, followed by a complete neck CT with contrast. Is it justified to submit a claim for a CT of the neck without and with contrast?
