Depending on the hospital, they may have a hardship program, too. Also, they may have charity program.
Here are some examples: one of my relatives had fairly good insurance with a reputable company, but even after the insurance the bill was $11,000! My relative called their billing department and allowed her to do $25 per month. If they have a charity program, and you qualify by income base, they could remove charges on the bill.
Another thing to consider, if you think the bill is inaccurate, you could request a detailed itemization of all the medical charges, and an explanation of all the medical abbreviations. It's not common to see ridiculous things like $100 aspirin! Sometimes they double bill for procedures, or tests/medical procedures that you were scheduled for (and they decided not to do) they go ahead and bill you anyway!
