Very upsetting. My appointment and consultation with Dr. Knezevic was very good. However, I received a bill from this office, which is incorrect. I have Medicare as my primary insurance and United Healthcare, Oxford plan as my secondary which I gave to Hackensack Meridian healthcare and I assume his office when I performed my Online Check-in.
