My question involves insurance law for the state of: Idaho

I was seen recently at the university of idaho student health office. I was forced to carry the Student Health Insurance Plan by the university. I was forced to pay for the entire year without the option of termination. I then had the opportunity to get health insurance through my wife's work but only could sign up for it during a certain time period wich happened to be in the middle of the school year. This forced me to have 2 health insurance providers. Later in the spring semester i got sick so went to the student health clinic. They told me that both insurance companies would cover all costs. Months later bills start rolling in from the clinic and a regional laboratory. The clinic now refuses to send a bill to my secondary insurance company on the grounds that it would be fraud for them to do so. I now have alot of medical bills and no money to pay. Is it fraud for them to bill the secondary insurance?, if not then what can i do?
