I have UC as a supplemental, that is until open season. I had periodontal work performed that I had to pay for upfront. The dental office helped me file my claim on this procedure. UC took 7 months to pay a small portion of it and only then after I turned them into every agency I could think of. Now they are telling me my regular dentist (that they used to pay) is not in their network and will not pay him. Can you say R-E-T-R-I-B-U-T-I-O-N. I highly do not recommend them and am dropping them ASAP.
