I couldn't tell you on a blanket basis what to do, but I can tell you there will be a difference if the denials you have are for something the office did wrong, incorrect coding, etc. I can also tell you from having been a claims examiner in a few places that they do keep flags for consistent denials for information and a provider is not consistent with supplying that information. for example, a carrier with a provider in their network who is submitting claims for a particular procedure that is incorrectly coded will have a match in their system every time the same type of claim comes across the system. There are other denials that it's expected the provider file a correction. Denials where it was a patient eligibility, or awaiting info from patient, those can be billed to the patient.
Again, I can't tell you one way or the other, If they were my claims I probably would take the time to go through them and maybe split the work up. For example, let's say you count 100 claims, I would probably try to get 15-20 of them done and gone through a day along with current work so that you don't get behind working on the old. I would then produce a report for the provider to sign off on the final ones you know you don't have much of a chance of collecting on. J M H O
