A medical bill doesn’t affect your credit score when you get it, or even when it’s a little late. It can only show up if it goes to a collection agency, and even then the three credit bureaus won’t list it for at least one year, won’t list it if it’s under $500, and remove it once it’s paid. Larger unpaid medical collections can still appear and lower your score.
2026 update: a federal rule that would have removed almost all medical debt from credit reports was struck down by a federal court in July 2025, so it never took effect. The bureaus’ own voluntary policies still apply, and some states ban medical debt reporting.
The rules that apply now
| Rule | What it means for you |
|---|---|
| One-year wait | A medical collection can’t appear until a year after it went unpaid |
| Paid medical collections removed | Once paid, it comes off your report |
| Under $500 not reported | Medical collections under $500 aren’t listed |
| Newer scoring models | FICO 9, FICO 10 and VantageScore 4.0 count medical collections less than older models |
These come from Equifax, Experian and TransUnion’s own policies, adopted in 2022 and 2023.
Will paying off medical bills improve your credit score?
If the bill is in collections, usually yes. Equifax, Experian and TransUnion remove paid medical collections from your report, so once the collection is paid in full and updated, it should disappear, and your score may go up. If the bill isn’t in collections, paying it won’t raise your score, because unpaid medical bills that aren’t in collections aren’t on your report in the first place.
Paying a medical bill on time doesn’t build credit, either. Doctors and hospitals don’t report on-time payments to the credit bureaus. The exception is if you put the bill on a credit card or a medical credit card, which are reported like any other card.
Do hospital bills affect your credit?
Hospital bills follow the same rules as any medical bill. They only appear if the hospital sends them to a collection agency or sells the debt, and then only if the balance is $500 or more and at least a year old. Nonprofit hospitals also have to give you time to apply for financial assistance before using “extraordinary collection actions” such as reporting you to a credit bureau.
FICO vs VantageScore: how medical debt counts
| Score | How medical collections count |
|---|---|
| FICO 8 (most used by lenders) | Counts unpaid medical collections like other collections |
| FICO 9 and FICO 10 | Ignore paid collections and weigh unpaid medical collections less |
| VantageScore 3.0 and 4.0 | Ignore all medical collections |
Mortgage lenders have started accepting newer scores, but many lenders still use FICO 8. So a medical collection that VantageScore ignores can still matter when you apply for a mortgage or car loan.
States with stronger protections
Several states limit or ban reporting medical debt to credit bureaus, including California, Colorado, Connecticut, Illinois, Maine, Maryland, Minnesota, New Jersey, New York, Oregon, Rhode Island, Vermont, Virginia and Washington. The details and start dates differ by state, so check your state attorney general’s website.
What to do if a medical bill is heading to collections
- Don’t ignore it. You have time, but use it.
- Ask for an itemized bill and check it for errors. See how to read an itemized hospital bill.
- Check your EOB. Make sure insurance processed the claim correctly. See what is an EOB.
- Ask about financial assistance. Nonprofit hospitals must have a financial assistance (charity care) policy.
- Ask for a payment plan. Most providers offer interest-free plans.
- If it’s already in collections, send a written request for validation within 30 days. See medical bill in collections: what to do next.
How to check your credit report
Get free weekly reports from all three bureaus at AnnualCreditReport.com. If you see a medical collection that’s paid, under $500, less than a year old or not yours, dispute it with the bureau online.
From 15 years in billing: many bills go to collections simply because the insurance claim was never processed right, for example the wrong insurance ID or a missing referral. Call the provider’s billing office before you pay a collector; fixing the claim often makes the balance much smaller or makes it disappear.

Frequently asked questions
Do medical bills affect your credit score?
Only if they go to collections. Even then, the three credit bureaus wait a year before listing a medical collection, do not list medical collections under $500, and remove paid medical collections.
Was all medical debt removed from credit reports?
No. A federal rule that would have removed most medical debt was struck down by a federal court in July 2025. The bureaus’ own policies still apply, and some states ban medical debt reporting.
How long before a medical bill shows up on my credit report?
At least one year after it became delinquent, and only if it has gone to a collection agency.
What should I do if a medical bill is sent to collections?
Ask the collector in writing to validate the debt within 30 days, request an itemized bill, check it against your EOB, and ask the provider about financial assistance and payment plans.
Will paying off medical bills improve my credit score?
If the bill is in collections, usually yes, because the credit bureaus remove paid medical collections from your report. If it isn’t in collections, paying it won’t change your score, since it isn’t on your report.
Do hospital bills affect your credit?
Only if they go to collections, and then only if the balance is $500 or more and at least a year old. Paid hospital collections are removed.
Does VantageScore count medical debt?
No. VantageScore 3.0 and 4.0 ignore medical collections. Older FICO scores, which many lenders still use, can still count unpaid medical collections of $500 or more.
