United Health Care (UMR) and CI

Does anyone on here have UMR United health insurance? I'm considering looking into a pair of CI's possibly and I was wondering if anyone had that insurance and if it was covered 100% or a fraction etc.

Also Is it worth doing CI and sacrificing what hearing is left in my left hear that wears AID. I am noticing that these digital aids are not good for me compared to the old analog ones. I really missed those analogs they sounded so much better than these newer ones. I currently have the Phoniak Niada 3 which is 8 years old now.
