Before You Set Up a Payment Plan

  1. Get an itemized bill. Check every line for errors and duplicate charges.
  2. Make sure insurance paid first. Compare the bill with your EOB. You should not owe more than your EOB says.
  3. Apply for financial assistance. Nonprofit hospitals must have a policy. Check where you stand with our federal poverty level calculator.
  4. Ask for a discount. Many providers cut the bill for paying in full or paying fast.
  5. Then ask for a 0% plan with a payment you can keep up with.

Rules That Protect You

  • Nonprofit hospitals must wait at least 120 days after the first bill before credit reporting, lawsuits or other extraordinary collection actions, and must give you 30 days' written notice first. You have 240 days to apply for financial assistance, and collections stop while a complete application is reviewed.
  • Credit reports: the three credit bureaus remove paid medical collections, wait a year before reporting unpaid ones, and do not report medical collections under $500.
  • Good faith estimates: if you paid yourself and the bill is $400 or more over your estimate, see our No Surprises Act calculator.
  • State laws: some states cap interest on medical debt or limit credit reporting. Check with your state attorney general.

Frequently Asked Questions

Do hospitals charge interest on payment plans?
Most hospital and doctor payment plans charge no interest, but it is not guaranteed. Always ask for a 0% plan before you put a bill on a credit card or take a loan.
How long do you have to pay a medical bill?
There is no single deadline. Many providers send bills for a few months before using a collection agency. Nonprofit hospitals must wait at least 120 days after the first bill before credit reporting or other extraordinary collection actions, and must give you 240 days to apply for financial assistance.
What is deferred interest on a medical credit card?
If you do not pay the full balance by the end of the promo, the card charges interest back to the purchase date on the whole original amount. The CFPB found patients paid about $1 billion in deferred interest from 2018 to 2020, with typical card rates of 26.99%.
Will an unpaid medical bill hurt my credit?
Under the three credit bureaus' current policies, paid medical collections are removed, unpaid ones are not reported until they are a year old, and medical collections under $500 are not reported at all. A federal rule that would have removed medical debt from credit reports was struck down in July 2025, so these are voluntary policies. Some states go further.
How much should my monthly payment be?
Pick an amount you can keep paying every month. Many providers will agree to a smaller payment or a longer plan if you ask, especially if you show your income. If your income is low, apply for financial assistance first.
