We have been using Dentrix for 10+ years at our clinic and originally, the software was able to do COB if the patient had a secondary insurance. Now, it wont allow it because the information it thinks its sending as Secondary, is actually primary info again causing a duplicate claim/error. There is no way to fix this other than inconveniencing patients to process secondary claims manually themselves, or, have the office have to physically get it signed/mailed to the secondary insurance causing a significant lag in processing/payment. Why can't this be fixed or seen as a priority? Lots of patients have 2 insurance plans..
