The hospital no longer owns the debt. They sold it to a collection agency.
It is out of the hospitals hands.

Look at them. The collection agency will be in one of the three.
Contact the agency.
Two things you can do:
Can you pay the bill in full? Make sure you are aware that when it goes to collections an extra charge may be added on. If you can pay in full request a pay on delete.
This is where you pay the bill in full, and they remove the item from your credit reports.
Ask for it in writing before you make payment in case they forget to "delete" the item later.
Collection agencies do not want payments.
You can also negotiate a settlement. You can offer a lower amount and they will mark the bill as "paid". This will still allow it to show on your reports for many years, but at least you saved a bit of money and kept them from suing you in court
