In general, insurance companies can also kick a patient out of a hospital if the insurance company believes no services are needed and/or the insurance runs out. You need to protect your daughter but in a legal fashion. So at this point, resort to as many creative options as you can. Start corresponding with the insurance company verbally and in writing and start conversing and writing your congressmen and senators (both at the local, state and federal level). Talk to the local paper. Your final options are to file a complaint with your state's department of insurance and to hire an attorney. You should be also obtaining professional independent opinions about your daughter's need for care and what could or would occur if she was sent home from the facility.
