Quoting SailorJerry:" I've considered myself to have "bad credit" because I have a hefty amount of unpaid medical bills. But ... [snip!] ... insurance? I have tons of random bills, ER visits like $900 a pop, a few ultrasounds,.most of these from when I was pregnant."
Yes, it can count on your credit report. Many hospitals are also getting the right to garnish your tax return to recoup their money.
You should be able to set up a monthly payment of any amount you can afford. Just tell them the amount you can pay and they should work with you. I've known people to pay them $20/month.
If you are aiming for a lump payment, many hospitals will cut you a deal if you pay in full.
Good luck and I hope it's paid off soon. I've been paying $200/month since my son's birth (18 months ago) and only have 3 payments left!
