Ask Dr. Z

My provider is doing a minimally invasive aortic valve replacement (25 mm CE Inspiris tissue valve) with an anterior mini thoracotomy. She accessed the right femoral artery and used fluoroscopic guidance. She wants to bill 34812 and 77001 (33405 is not a primary CPT for 34812 or 77001). Should I be using an unlisted CPT or just bill 33405? She stated mini-nonsternotomy approach to valve replacement. You need open femoral artery exposure and fluoro. It's my understanding that expose no matter how it's exposed is included. Is this correct in only billing 33405, or should I be using another CPT?
