I am new to ophthamology billing and I am hoping someone can help me understand how to correctly bill Co-Managed patients when cataract surgeries have been performed using the 55 modifier. If the surgery took place on 8/19 and the patient was released to the co-managing physician on 8/25 how do I correctly bill this patient for my surgeon if he sees this patient one last time on 8/25 and releases him at that time to Dr. X who is also co-managing? Thanks in advance for any help!
