<human>: Back in 2013, I was in a car accident. An ambulance ride and hospital trip later, there was a bill totaling $13,000. I remember giving the EMTs and nurse my information (ID, updated address, and medical card). I was insured with my employer's health benefits at the time. During those months, I was dealing with all this + my mom's death and did not have a good tracking method of everything that was going on (not an excuse, just a confession of being unorganized). 

Now, I just received a letter from a collection agency for the ambulance ride to the updated address I'm currently at--I just took care of that. I couldn't find anything about the ER stay, so I went to the hospital and saw the balance of $11 which is now with the Department of Revenue.

I reached out the insurance company and since timely processing has passed (I'm also no longer insured by them as my company switched to a different company), they don't want to pay for it. They noted the only exception is if the address was wrong, and in which, it was. The hospital took down my outdated address from my ID, and even then, they wrote it down as "court" instead of "circle." 

Even with this, the insurance company is being pretty adamant in not wanting to pay, so I just obtained an itemized statement with the incorrect address to fax them and have not heard back. With the 11k balance in my face, I'm scared and don't know what the next steps would be. Anyone ever have to deal with health insurance companies and/or Department of Revenue? Please help/advise.

Can you provide a brief overview of the text?
