I have Medicare and a Medicare Supplemental Policy with Banker's Fidelity. I have never had any problems so far. CMC doctors offices accept my coverage. We live in South Carolina and my husband has the same coverage with Medicare and Banker's Fidelity, he had surgery in Charlotte with no problems. CMC accepted both and the bill was paid.
My OB/GYN docs are not owned by any hospital and they accept my coverage. So far we haven't had any med clinic, doc or hospital not take the coverage we have. I sure hope nothing changes.
