Dear E.,
Try applying for Healthy Families for your daughter.
I am an insurance agent in CA, (not currently working in that field however) and yes, you can be denied health insurance that is an "individual" policy.
You can talk to the agent or underwriter....sometimes they will give you something in writing that says your daughter must be "sign, symptom, and treatment free" for a certain period of time before you can reapply.
It sucks, I know....but I would really try getting her on Healthy Families. They go by income guidelines and not health history.
Employer sponsored health plans can't deny you coverage for health conditions so I don't know if you have that option through employment. Many people, including myself, can't get health coverage unless it's through my employer because of my health history.
My son had Healthy Families and it was excellent coverage. Most pediatricians accept it. In fact, you may be able to get an application through the pediatrician's office.
You can find more information at www.mrmib.ca.gov
Best wishes!
