What Did That Surgery Cost?

 I was told that I would pay $300/day for the first five days in the hospital.  My insurer received about $30,000 in bills at their heavily discounted rate.  My share so far seems to be $0.  I did not even get billed for the $300/day hospital charges.  I can see that a bill was submitted to Blue Cross but I guess because they were in-network no part for me to pay.
