Insurance companies deny claims chisel UCR fees to a point where dentists cannot cover the cost of procedures that you might need so are reluctant to offer the treatments you need.. dental insurance companies deny claims all the time and then point the finger at the dentist so they do not look bad.. the fun part is as being a provider the dental insurance companies forbid in their agreements that dentists are not allowed to show what they were paid for a procedure.. example the ins co instead of denying a claim on your behalf will send a payment to the dentist D0120 FMX (X-rays) payment $0.. in the insurance industry that is classified as a paid claim in the amount of $0. The dentist then sends the patient a demand for $100 for example; the patient then calls their insurance who tell their customer who pays them monthly., no the dentist was paid. The patient then accuses the dentist of trying to scam them, the dentist cannot say we were paid $0 so the patient ends up angry and in collection.. support the dentist not the insurance business.
