Medical bills and EOBs: how to check them and get help

Insurance · 3 min read · Updated 1 November 2026

In short: after you get care, your insurer sends an explanation of benefits (EOB). It is not a bill: it shows what was charged, what the plan paid and what you may owe. Compare it with the provider's bill, ask for an itemized bill, and don't be afraid to question mistakes. Many hospitals offer financial assistance and payment plans.

Reading an EOB

Amount billed: what the provider charged.
Allowed amount: what your plan agreed to pay for the service (for in-network care).
Plan paid: the insurer's share.
You may owe: your deductible, copay or coinsurance. This is the number your bill should match.
Denied or not covered lines, with a reason code. You can ask the insurer to explain or appeal.

Checking a bill

Wait for the EOB before paying, and check that the amount you owe matches.
Ask the provider for an itemized bill listing every service and charge.
Look for duplicate charges, services you didn't receive and wrong dates.
If something is wrong, call the provider's billing office, write down who you spoke to, and ask for a corrected bill.

Surprise bills

The No Surprises Act protects most people with insurance from surprise out-of-network bills for emergency care and for some care at in-network hospitals. If you don't have insurance or pay yourself, you can ask for a good faith estimate before scheduled care, and dispute a final bill that is much higher. CMS explains these rights.

If you can't pay

Ask about financial assistance: non-profit hospitals must have a written financial assistance policy, and many reduce or cancel bills for people with lower incomes. Ask even if you think you won't qualify.
Ask for a payment plan, ideally without interest.
Ask about a self-pay discount if you have no insurance.
Be careful about putting a medical bill on a credit card or special medical credit card, which can charge high interest.

Medical debt and your credit

If a medical bill goes to a debt collector, you have rights under federal law, including asking the collector to verify the debt. The national credit bureaus say they no longer include paid medical collections or medical collections under $500 on credit reports. Rules have changed several times, so check the CFPB's current information. See Credit reports and credit scores.
