75774

I am confused on when it is appropriate to bill CPT 75774. I bill for a vascular interventionalist.

What is considered the "basic exam"

If my doctor is performing a diagnostic study and enters through the radial artery he performs an abdominal aortogram and then selectively engages the right common iliac artery and does selective injections and then advances the catheter to the common femoral artery and does selective injections from there also. He does this on the left side also

I am billing 36246 x2, 75710, 75625 would it be appropriate to bill 75774 and if so, x2 or 4?

TIA!!
