We have an opthalmologist who states that 90% of her visits are medical and not routine. The patients often come in with a complaint such as blurry vision or seeing spots, some have diabetes and she's performing an exam on them but when we bill the medical plans some deny stating they are not the contracted payer and then we also get denials from the vision plan. The vision plans also do not pay very much. How do we know when to bill to the medical plan vs the vision plan?
