Can we be billed for both a complete (76770) and limited (76775) retroperitoneal ultrasound?? I *think* they actually just did a limited but need to call the doctor's office to get a copy of the script to be sure. The purpose was specifically to measure the cysts on one kidney and I didn't notice the technician doing much other than that (on dh but ds was with us so my attention was not undivided, maybe she did a quick look-see). So it should just be the limited 76775 which our insurance covered. But we also got a notice from our insurance, and followed by a bill from the hospital, that the complete 76770 was not covered because it exceeded our allotment for diagnostic services for the year. It doesn't seem like the hospital should be paid for a limited ultrasound by the insurance company and also bill us for a complete one <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/irked.gif" style="border:0px solid;" title="irked">. Any billing experts in the house?
