Yes, to bill 93312-Echocardiography, transesophageal, real-time with image documentation (2D) (with or without M-mode recording); including probe placement, image acquisition, interpretation and report, they do need to be stated under procedure description.
After noticing a few denials, we requested our Cardiologist to add this step to the existing template (if he places the prob). Since then, we didn't have any issues.
Otherwise, it qualifies only for 93314 - Echocardiography, transesophageal, real-time with image documentation (2D) (with or without M-mode recording); image acquisition, interpretation and report only.
HTH.
