Frequently Asked Questions

How do I dispute a medical bill?

First, request an itemized bill from the hospital. Review each line item against your Explanation of Benefits (EOB) from your insurance company. Identify any errors — duplicate charges, services not received, incorrect coding, or balance billing. Then send a written dispute letter to the hospital's billing department listing each error with supporting documentation. Send via certified mail for proof of delivery. Up to 80% of medical bills contain errors, so it's worth checking.

Can hospitals send medical bills to collections?

Yes, hospitals can send unpaid bills to collection agencies. However, as of 2023, the three major credit bureaus (Equifax, Experian, TransUnion) no longer report medical debt under $500 on credit reports. Medical debt also cannot be reported until after a one-year waiting period. Always dispute billing errors in writing before they reach collections — this creates a paper trail that protects you.

How long do I have to dispute a medical bill?

Under the No Surprises Act (effective January 2022), you have 120 days from the date of a surprise bill to dispute it through the federal independent dispute resolution process. For other billing errors, most hospitals accept disputes within 180 days. Insurance appeals must be filed within 180 days of a denial. Act quickly — the sooner you dispute, the more leverage you have.

What is the No Surprises Act?

The No Surprises Act (effective January 1, 2022) protects patients from surprise medical bills. It prohibits balance billing for: (1) emergency services regardless of network status, (2) non-emergency services by out-of-network providers at in-network facilities, and (3) air ambulance services. If you believe you've been surprise-billed, you can file a complaint at cms.gov/nosurprises or call 1-800-985-3059.

Should I pay the undisputed portion of my bill?

Yes. If only part of your bill is in dispute, continue paying the undisputed portion to avoid your account being sent to collections. In your dispute letter, clearly state which charges you are disputing and which you acknowledge. This shows good faith and protects your credit while the dispute is being resolved.
