Learn how to identify common ER billing errors including upcoding, facility fees, and surprise billing. Save $500-$10,000 on your emergency room bill.
Potential savings: $500-$10,000
Emergency room visits are among the most expensive healthcare encounters, with the average ER bill exceeding $2,200. Studies estimate that up to 80% of medical bills contain errors, and ER bills are particularly prone to mistakes due to the fast-paced, high-acuity environment. Understanding common ER billing errors can save you hundreds or even thousands of dollars.
What Is Emergency Room Visit Billing Errors?
Emergency room billing uses a five-level coding system (CPT codes 99281-99285) to classify visits by severity. Level 1 (99281) is a minor problem requiring minimal evaluation, while Level 5 (99285) represents a life-threatening condition requiring immediate, significant intervention. Hospitals also charge a separate facility fee on top of physician charges. These layered charges create multiple opportunities for billing errors.
Common Billing Errors
Hospitals may bill a higher-level ER visit code than your condition warrants. For example, billing a Level 5 (99285) for a condition that only required a Level 3 (99283) evaluation. The difference between levels can be $1,000 or more.
CPT 99283 ($500) vs 99285 ($2,500)Even at an in-network hospital, individual providers (radiologists, anesthesiologists, emergency physicians) may be out-of-network and bill separately at higher rates. The No Surprises Act now protects patients from many of these charges.
Out-of-network vs in-network physician feesSome hospitals incorrectly charge multiple facility fees during a single ER visit, especially when a patient is moved between departments or observation areas. You should only see one facility fee per visit.
Trauma activation fees ($1,000-$18,000) may be charged even for non-trauma presentations. If you walked into the ER or your condition was not a trauma case, this charge may be erroneous.
How to Spot These Errors on Your Bill
- 1
Request an itemized bill and compare the ER visit level (99281-99285) against your actual symptoms and treatment received.
- 2
Check for separate bills from physicians, radiologists, or anesthesiologists who may have billed out-of-network.
- 3
Look for duplicate charges on the same date of service, especially facility fees or nursing charges.
- 4
Verify that any trauma activation fee matches an actual trauma response and not a routine ER visit.
- 5
Compare the medications listed on your bill against what you actually received during the visit.
Frequently Asked Questions
What is the most common ER billing error?
Upcoding is the most common ER billing error. This occurs when a hospital assigns a higher-level visit code (like 99285) than your condition warrants, resulting in significantly higher charges. Studies show that many hospitals routinely bill Level 4 or 5 for visits that should be Level 2 or 3.
Can I dispute an ER bill after I've already paid?
Yes, you can dispute an ER bill even after payment. Most states allow you to request a refund for billing errors. Start by requesting an itemized bill, identify the error, and file a formal dispute with the hospital's billing department. You may also file a complaint with your state's attorney general or insurance commissioner.
Does the No Surprises Act protect me from ER surprise bills?
Yes, the No Surprises Act (effective January 2022) protects you from surprise out-of-network bills for emergency services. You cannot be charged more than your in-network cost-sharing amount for emergency care, regardless of whether the providers or facility are in your insurance network.
