I was in an auto accident, hit by an uninsured motorist. I have uninsured motorist coverage through State Farm. I was taken to the emergency room.

I live in Jackson, MS. I gave my health insurance (Cigna) at the hospital and the hospital billed them. The bill was $13,000 and Cigna paid $4,000 since the hospital was in-network. I knew from my Cigna EOB that I owed 30%, around $1,500. I called to get my statement so that I could pay the balance. I was told that it was mistakenly sent to Cigna since it was an auto accident. They have already cashed the Cigna check and now they have mailed me a statement saying the remainder I owe is $1,500. The hospital said that they would go after State Farm to get the remainder $7,500 back and if State Farm didn''t pay it, then I would be responsible for it. She said they make more money when it is an auto accident and they are not willing to give that $7,500 up. But they already cashed the Cigna check. Isn''t that accepting the health insurance terms?? Please provide any insight you can. State Farm agent hasn''t heard of this and she argued with the hospital but they won''t budge. Thanks
