Our office is doing AAA Ultrasounds and were under the impression that we needed to bill Michigan Medicare for a G0389 for a screening code and using the screeing guidelines that they publish, BUT after further review it is looking like the only way we are able to bill for this code is if it is part of the welcome to medicare exam? Does anyone bill with this code and if you do how is it going and what is the criteria that you use. I am also thinking that if we can not use this code we could use the 93978-76770 or the 97979-76775 depending on the exam and if they meet that diagnosis requirments?
