Hi. Claims for exam (92014, 92004 with modifier 57) and in-office laser 66821 getting denied. I was told to add modifier 57 to the exam when a decision for surgery was within 24 hours, but was not told that the 66821 also needed a modifier. Medicare split the claim and paid for the exam, but are denying the laser for a wrong modifier. I resubmitted with modifier 59 but that was also denied. Is there another modifier or did I use the wrong modifier on the exam? Thank you!
