Ask Dr. Z

Please do NOT include any actual patient medical records with your question. Your guide states that diagnostic imaging (when medically necessary) is separately billable when done at the same time as LE revascularization if not recently performed but not for confirmation of a known lesion seen on prior cath-based angiograpy,diagnostic CTA or MRA. My question is, since I am not familiar with alot of these tests, if the patient had a vascular study done about a month prior and imaging was obtained using gray-scale, pulse wave and color doppler, would the diagnostic imaging at time of revascularization still be seperately billable since they had the vascular study? Would it make a difference if patients symptoms had changed or condition worsened? I'm just unclear in these kinds of circumstances and would appreciate any assistance you may be able to offer.
