30600 (Oroantral fistula closure) was denied by medical because dental services are not processed under patients plan. Initially the medical insurance Paid $961.36 but reviewed the claim and now almost 4 months later is asking for a refund of the $961.36. I used diagnosis codes of J32.0 and G50.1. I called the medical insurance and they said I would need to file an appeal to prove medical necessity and it could be reversed. Im new to billing medical and we are an Oral Surgery office. Any help would be greatly appreciated.
