Understand My Medical Bill
You don't need to already know medical billing terminology to get help. Start with the problem you're experiencing — a confusing charge, a bill that seems too high, or a bill that doesn't match your EOB — and this tool helps you make sense of it and figure out your next step.
Understand My Medical BillBefore You Pay a Medical Bill
Before paying, consider checking the following:
- Provider and patient information
- Date of service
- Charges listed
- Itemized details
- Insurance and EOB information
- Your patient responsibility amount
- Possible billing errors
Check Your Medical Bill
Four ways to look closer at what you've been charged.
Request an itemized bill
A lump-sum total doesn't show what you're actually being charged for. An itemized bill breaks down every line.
Request an itemized bill →Check for billing errors
Duplicate charges, upcoding, and phantom services happen more often than most patients expect.
See common billing errors →Understand medical billing codes
CPT, ICD-10, and HCPCS codes explain exactly what was billed and why.
Decode my billing codes →Compare your bill with your EOB
Your bill and your insurer's Explanation of Benefits should tell a matching story. If they don't, that's worth a closer look.
Read my EOB →Something Doesn't Look Right?
Common situations patients run into:
- A charge you don't recognize
- A charge that appears twice
- A charge for a service you don't believe you received
- A bill that doesn't match your EOB
- A total that just seems too high
We can't make individual medical, legal, or insurance determinations for your situation, but these resources can help you figure out what to check next.
Can't Afford Your Medical Bill?
Depending on your situation, you may have options to explore before paying the full amount. These commonly include payment plans, hospital financial assistance (sometimes called charity care), and negotiating the balance directly with the provider.
My Insurance Denied Something
Sometimes a medical-billing problem is actually connected to an insurance claim or coverage decision. If your insurer denied a claim, reviewing the denial reason and your plan's appeal process is usually the next step — though outcomes and rules vary by insurer and plan.
What If the Provider Was Out of Network?
Out-of-network billing is a common source of unexpectedly high medical bills, and how it's handled can depend on your plan and situation. A dedicated guide on this topic is in progress — check back soon, or start with Understand My Medical Bill if you already have a bill in hand.

Understand Your Healthcare Costs
Medical bills connect to broader concepts like your patient responsibility, deductible, copay, coinsurance, and out-of-pocket maximum. Understanding these can help you make sense of any bill you receive.

- Insurance adjustment
- The difference between the provider charge and the negotiated or allowed amount.
- Deductible

- Copay
- A fixed amount you typically pay for a covered service.
- Coinsurance
- A percentage of the cost you're generally responsible for after your deductible is met.

Should I pay a medical bill before checking it?
Generally, it's worth reviewing a bill before paying it in full. Check it against your itemized bill and your EOB, and watch for possible errors, before sending payment.
How do I know if my medical bill is correct?
Compare your bill line by line against your itemized bill and your insurance EOB. Look for duplicate charges, services you don't recognize, and amounts that don't match what your insurer says you owe. Check my bill for errors →
How do I get an itemized medical bill?
You can request one directly from the provider's billing department, in writing or by phone. It should list each charge separately rather than as a single lump total. Request an itemized bill →
What should I do if my bill is higher than expected?
Start by requesting an itemized bill and comparing it with your EOB. A higher-than-expected bill can come from several sources, including facility fees, out-of-network care, or a billing error.
What if my medical bill doesn't match my EOB?
A mismatch is worth investigating before you pay — it may point to a billing error, a claims-processing issue, or a coverage question with your insurer. How to read an EOB →
How do I dispute a medical bill?
Disputing a bill typically starts with contacting the provider's billing department, explaining the specific charge you're questioning, and following up in writing if needed. How to dispute a medical bill →
What if I can't afford my medical bill?

What if my insurance denied the claim?

What does an EOB mean?
An Explanation of Benefits (EOB) is a statement from your insurer showing what was billed, what insurance paid, and what you may owe. It is not a bill itself. How to read an EOB →
What is an out-of-network medical bill?
It's a bill from a provider or facility that isn't part of your insurance plan's network, which can change how much your insurer pays and how much you owe. Rules vary by plan and situation.
