I am thinking 70K is way over what it should be...maybe 1 to 2K a day per day in the hospital so maybe 16K.
Most insurances...have either a 2K to 5K deductible then either pay 80 - 100% of the rest.
So my guess would be about $3,500, after the insurance works itself out...and double check every piece of paper from the insurance company verses the actual hospital bill...and then resubmit each bill from the hospital to be reviewed again and even call to double check it was ll processed correctly. I find mistakes all the time in verses what our insurance pays vs what they should have paid.
Don't pay anything to the hospital until it is determined that the insurance has covered everything, BUT do call the hospital billing department to let them know you are still working with the insurance and do intend to make payment...they will then extend you either 30, 60 or 90 days to finish working with the insurance company.
Then when the final total is determined...go with your SS and talk with the billing department in person and tell them how much he can afford to pay a month even if it is $20.00...he can pay on it for years as long as he pays it will not effect his credit or future prospects.
Don't panic...and keep all your paperwork on everything..start a notebook...3-ring binder and keep it all together.
I hope your SS is much better...and this is not going to hurt him in the long run.
