How do I dispute an emergency room bill?

Start by requesting an itemized bill and your UB-04 form from the hospital. Compare the CPT billing codes to your medical records, and look for upcoding, duplicate charges, or services you did not receive. MedicalBillReview.net can review your bill for free and identify errors you can formally dispute.

Is the ER bill review completely free?

Yes. MedicalBillReview.net provides a completely free, independent review of your emergency room bill. There is no cost to you at any point.

What is upcoding on a medical bill?

Upcoding is when a hospital bills for a higher level of care than was actually provided. For example, billing CPT code 99285 (the highest complexity ER visit) when the actual visit was a routine 99282. This is one of the most common and costly billing errors on ER bills, and it is something we specifically check for in every review.

What does the No Surprises Act cover for ER bills?

The No Surprises Act protects patients from unexpected out-of-network charges at in-network facilities, including emergency rooms. In most cases, you cannot be billed more than your in-network cost-sharing amount for emergency care, regardless of which doctor treated you.

What billing errors are most common on ER bills?

The most common ER billing errors include: upcoding (billing a higher level of care than provided), unbundling (charging separately for services included in a flat rate), duplicate billing (charging twice for the same service), and errors in medication quantities or supply units.

How do I get an itemized bill from a hospital?

You have a legal right to an itemized medical bill. Contact the hospital billing department and specifically request an itemized statement and the UB-04 claim form. Under federal law, hospitals must provide your medical records within 30 days of a written request.

Angel Perozo Sosa — Medical Billing Advocate

Lead Medical Billing Advocate | MedicalBillReview.net

Hi, my name is Angel Perozo Sosa. I created this website because of something I went through personally. I went to the ER and later received a medical bill for about $4,000. What shocked me wasn't only the amount — it was the fact that no one could clearly explain why it was so high. I called, I asked questions, and I still felt like I was getting vague answers.

So I did what most people end up doing: I tried to figure it out myself.

I started learning how medical bills work — things like itemized charges, billing codes, facility fees, insurance adjustments, and what you can actually question. The more I learned, the more I realized something important: a lot of people are confused because they don't understand the bill. They're overwhelmed, scared, or don't know what to ask.

That's why I built this site. My mission is simple: help you understand your bill in plain English, know what's normal (and what's not), and feel confident taking the next step — whether that's requesting details, disputing something that looks wrong, or getting help reviewing it.
