This is ludicrous! I have insurance, & still this will completely drain me financially. I'm at the point where I almost think it would be easier to declare bankruptcy and start over!I worked in insurance for over five years. Not this kind of insurance, but it was a kind of health insurance.
a) Get a letter of "medical necessity" drafted by your primary care physician.
b) Call the insurance company and ask about the policies concerning emergency treatment. Don't accuse them of anything. They get cussed out all the time and it will not help you. Be nice and start from the assumption that there must be some mistake.
c) If you make no progress with that, have a lawyer send the insurance company a letter requesting a copy of your records. This sometimes makes them look very carefully at the bill and sometimes is enough to get you whatever benefits you are legally due. Which may not be your wildest dreams of avarice, but may stave off your desire to declare bankruptcy.
If you do have a lawyer request your medical records, expect the insurance company to come back with a form letter stating they need a third party auth. Yes, a lawyer will need a third party authorization to get your medical records, but I wouldn't bother supplying them with one at the start. Just make the request without it and supply it if you really need to. If you get your bill paid because a lawyer wrote them, your lawyer doesn't really need your records. The initial inquiry sometimes gets the claim looked over more thoroughly. I am basically recommending this as a scare tactic.
There are actually a lot of errors made in paying complex medical bills at insurance companies for the simple reason that the claims processor may not see an 8 day hospital stay all that often and may have about 10 minutes in which to look your bill over and decide what is payable before moving on. I had to process 60 claims a day to keep my job. This meant I had minutes to decide what the benefits were and people who were very fast were actively rewarded for it. I often cleaned up their messes and, no, this did not get me promoted or anything, even though it sometimes kept the company out of court because the people were threatening to lawyer up.
Best.
