Kaiser is absolutely awful! They won't pay if you have complicated medical issues and simply don't care. They only care about saving money. They hurt me tremendously, and I am still in pain from their lack of care. When I filed a complaint with Kaiser, they offered me extended coverage and then reneged on their offer.
In addition to all the pain they caused me, I now have to pay for the extended coverage bills they were supposed to cover. Very cruel and unethical! Their complaint process is a joke and will now cost me thousands. Don't use Kaiser unless you want to be maimed or be broke!
