Catheter Placement & Diagnostic Angiography

Can a 75716 & 36246 be billed together if there is one puncture site? I'm a little confused by the CPT® guidelines under "Vascular Procedures, Aorta and Arteries." A therapeutic procedure is not being performed. Can the cath placement (36246) be coded in addition to the 75716?

CCI edits state the 2 are not bundled, yet I have an insurance carrier doing just that.

McKesson Claim Check says the catheter placement is included in the dagnostic angiography, and if the 2 are performed together, the angiography is the code that gets reimbursed. But my gosh, the catheter placement is worth 4.5 times the RVUs of the diagnostic angiography (when done in the radiologist's office). If they're going to bundle the 2, why would a physician even consider billing the 75716 instead of the 36246? Yet to report only the 36246 isn't correctly reporting the entire service provided. I'm confused....
