Got a hospital bill you cannot pay? Here is what to do.

A free, plain guide for medical bills in the United States: what to check, how to ask for financial help, your rights on surprise bills and debt collectors, real deadlines, and letters you can copy. Nothing you type leaves your device.

Read this first

  • This is general information, not legal advice. Rules differ by state and by hospital.
  • It is for hospital and medical bills in the United States.
  • If you have been sued over a bill, do not wait. Answer the court papers by the date they give, and contact free legal aid now: find legal aid near you. If you do not answer, the court can rule against you without hearing your side. (CFPB)
  • Your own bill, notice or court papers come first. If a date on them is earlier than a date here, use theirs.

Your bill, step by step

Answer a few questions. We will show what to do, in order, with real deadlines. You can skip any question.

1 of 6Who sent the bill?
2 of 6Do you have health insurance?
3 of 6Was it an emergency, or did you choose where to go?
4 of 6What date is on the first bill?
5 of 6Has it gone to collections?
6 of 6Your household and income (optional)

Only to compare your income with the federal poverty guideline, here on your device. Many hospitals use it to decide who gets free or cheaper care. Not required.

Where do you live?

Pick your answers above. Your steps will show here.

Your dates

We count from the dates you typed in questions 4 and 5. That is the safe choice: you got the letter a few days after the date printed on it, so your real deadline may be a little later. If your letter gives a date, your letter comes first.

Write your letters

Stays on your device. What you type here is not sent anywhere or saved. When you leave the page, it is gone, so copy or download your letter first. Do not type your Social Security number.

Fill in what you know. Empty boxes show as [brackets] in the letter so you can fill them in by hand. The letters are short, firm and polite. The ones that fit your answers are shown.

Your letter

Before you send it

  • Sign it and keep a copy.
  • Send copies, not originals, of the bill or the collector's letter.
  • If you mail it, ask the post office for proof that it was delivered.
  • Write down the date you sent it.

What to say when you call

Call the billing number on the bill. Have the bill in front of you. Write down the date, the time and the name of each person you talk to.

A call is a good start, but send the important things in writing too. A letter leaves a record.

Where every rule and number comes from

We read each of these on November 13, 2026. Every deadline, dollar amount, percentage and phone number on this page traces to one of them. Our full research log, with the exact rule, who it applies to, a short quote and what we could not verify, is public: research-log.txt.

Who made this, and how to correct it
