What kind of documentation is required to be in the report when a physician does a selective renal angiography during heart cath. I have seen that is is required to have a complete renal ultrasound report even reporting on venous phase. Is this really required? I have been able to finally get my doc's to say whether they selectively or non selectively engaged the renal artery but I am really not clear on what needs to be in the documentation. Thanks alot, shelly.
