Whatever you have read negative about Ambetter you can take to the bank. Fraud is a good word for them.
In my experience, I would have to believe they have been responsible for deaths. It's hard enough to get a PCP, but God help you if you need a specialist. If you are lucky enough to find a specialist who will put up with them and take the insurance, try to get them to approve a procedure. Going to the emergency room with classic symptoms of a heart attack will be dismissed as not medically necessary and not paid.
They refused as not medically necessary to authorize an MRI for what turned out to be 3 bulging disks. Had to appeal to the state to get them to pay for it. Write your state senators and representatives.
File complaints against your state insurance commission. They need to be put out of business.
