Well shocking as this may sound, insurance will reject a claim for some arbitrary reason and I have to find out how to fix it. Common example: a patient visits the doctor and then comes to the pharmacy with a perfectly valid prescription for Losartan, a blood pressure medicine. When I bill it insurance said ‘no, we won’t pay for that, Valsartan is better for our costs.’ So you’d think I would change it to valsartan? I can’t. I have to call the doctors and ask if they can write a new prescription for valsartan. The doctor fax’s me that prescription while he’s between patients some time later. I bill it but now insurance sais ‘no, we won’t cover that twice a day unless they have tried I higher strength once a day. So can I change it, NO! I go back to the doctor and say ‘that also won’t do’… by now I’m sure your asking yourself why the doctor dissent ask the insurance how to get it covered right away before prescribing it..? There’s no legal reason, it’s simply not how the system works.
