Billing errors are a common issue in healthcare and can lead to overpayment, delayed insurance processing, or unnecessary collections activity. Errors may occur at any stage of the claims and billing process, from provider documentation to insurance payment application. Understanding common billing errors and how to fix them helps individuals protect themselves financially and resolve issues efficiently.
What a Billing Error Is
A billing error occurs when a medical bill or insurance claim contains incorrect information that affects how charges are calculated or paid. Errors may involve patient details, services billed, insurance application, or cost-sharing amounts.
Billing errors do not always mean fraud. Many errors are unintentional and result from administrative mistakes or system issues.
Common Types of Billing Errors
One common error is duplicate billing, where the same service is billed more than once. This may appear as repeated charges on a bill or Explanation of Benefits.
Incorrect coding is another frequent issue. Services may be coded incorrectly, making them appear non-covered or more expensive than they should be.
Other errors include billing for services not received, incorrect dates of service, wrong provider information, or misapplied deductibles and copayments.
Insurance Processing Errors
Errors can also occur on the insurance side. These may include incorrect application of network status, failure to apply negotiated rates, or improper calculation of patient responsibility.
Coordination of benefits errors may occur when a patient has multiple insurance plans and the wrong insurer is billed first.
How to Identify a Billing Error
Identifying errors begins with comparing medical bills to Explanations of Benefits. The amount a provider bills should match the patient responsibility shown on the EOB.
Reviewing itemized bills helps confirm that all listed services were actually received. Unexpected charges, unfamiliar providers, or amounts higher than expected are common warning signs.
Keeping records of visits, payments, and communications makes error detection easier.
Steps to Fix a Billing Error
The first step in fixing a billing error is contacting the provider’s billing office. Request clarification and ask for an itemized bill if one was not provided.
If the issue involves insurance processing, contacting the insurance company may be necessary. Insurers can explain how the claim was processed and whether corrections or reprocessing are needed.
In many cases, providers can submit corrected claims to resolve errors.
Correcting Coding Errors
If a coding error is suspected, the provider may need to review medical records and submit corrected codes. Coding corrections often result in claim reprocessing and adjusted patient responsibility.
Patients may request that providers review coding if services appear inconsistent with care received.
Handling Duplicate or Overpaid Charges
If duplicate charges are identified, patients should notify the provider immediately and request correction. Overpayments should be refunded once errors are resolved.
Keeping proof of payment helps support refund requests.
Appealing Billing-Related Denials
Some billing errors lead to claim denials. In these cases, filing an appeal with supporting documentation may be necessary.
Appeals related to billing errors often succeed once corrected information is submitted.
Time Limits and Follow-Up
Billing corrections and appeals are subject to time limits. Acting promptly helps preserve rights and prevents accounts from being sent to collections.
Following up in writing and keeping records of conversations helps ensure issues are resolved.
When to Escalate a Billing Issue
If billing offices or insurers do not respond or refuse to correct clear errors, escalation may be appropriate. This may include requesting a supervisor review or filing a formal complaint.
Persistent errors should not be ignored, as unresolved issues can affect credit or coverage.
Preventing Future Billing Errors
Verifying insurance information before receiving care, reviewing EOBs promptly, and asking questions early can reduce billing problems.
Staying organized and proactive helps prevent small errors from becoming costly disputes.
Key Takeaways
Billing errors are common and can occur at multiple stages of the healthcare payment process. Comparing bills to Explanations of Benefits, contacting providers and insurers promptly, and keeping thorough records help individuals identify and fix errors before they result in unnecessary costs or collections issues.
