I have a question an Iowa Medicare Denial. The patient came into the ER with a dislodged feeding tube- I billed out the E/R visit for it. Then, that evening, he came back and the physician did mild dilation of gastrostomy tract and gastrostomy tube re-insertion. I billed out for the procedures that time and put a 25 modifier on the E/R visit from that morning. Medicare is denying for the procedure codes. Is this correct and that I can't bill for the procedures even though the E/R visit and the procedures were 12 hrs apart?
