Is it legal for an insurance company to not cover you if you stay with that company but change policies? - hmo law

I'm trying to health insurance from Blue Cross / Blue Shield of Illinois get. I had, and the HMO policy with them for 3 years. My policy is with them is almost exhausted, shortly after 1 March. I tried to get another policy with them. I understand that I am completely cover because it was covered with them for 3 years. Was he wrong? You can reject me like everyone else? Does not accept my pre-existing medical conditions? I thought they were doing, because she had been to support that amount of time. I know nothing about the law. Is there somewhere I could look to know my rights in this area? I should know soon. I will not be without insurance.
