I have CIGNA PPO and an annual dental max limit of $1500 - yes, it sucks. I need to get (2) D2740, D6750 and D6240 but clearly it is WAY over the max amount allowed. Has anyone ever asked their HR to increase dental coverage and how did you do this? Or has anyone ever appealed their dental company after something like this was performed? It is major restorative, but the insurance and HR might consider it as cosmetic, but I hate the way my teeth look and it's really affecting the way I am. Any serious answers would be greatly appreciated. Thanks.
