Need to code a bladder ultrasound (76856) and a post void residual ultrasound (51798) on same day. They were performed about 1/2 hour apart. I've tried submitting with Modifier 59 (denials), and then tried Modifier 51 & 59 together (more denials).
Another scenario I'm encountering is 2 post voids done same day at different sessions. Should I bill 51798 as 2 units with no modifiers or 51798 & 51798 with modifier 59?
Any help appreciated!
