How to Dispute Medical Charges
How do I dispute a charge on my medical bill?
Request an itemized bill, compare it to your EOB to identify the specific error, and call the provider's billing department first. If they refuse to correct it, send a formal dispute letter via certified mail with copies of your EOB and medical records as evidence.
After you have identified an error on your medical bill, your first step should be a phone call to the provider's billing department. Often, simple errors can be corrected over the phone. However, if the billing department is uncooperative, or if the dispute is complex, you will need to escalate your complaint by writing a formal dispute letter. A well-written dispute letter is a powerful tool that creates a paper trail, shows you are serious, and forces the provider and your insurance company to formally respond.
The Dispute Process: Step-by-Step
Complete Action Plan
- 1.Gather Your Evidence: Collect your itemized bill, EOB, and medical records. These are the foundation of your dispute.
- 2.Identify the Specific Error: Be precise about which charges are wrong and why. Use CPT codes and dates of service.
- 3.Make a Phone Call First: Call the provider's billing department. Explain the error clearly and document the call (date, time, person's name, what was said).
- 4.Write a Formal Dispute Letter: If the phone call doesn't resolve it, put your dispute in writing using certified mail.
- 5.Notify Your Insurance Company: Send a copy of your dispute letter to your insurance company. They have an interest in not paying fraudulent claims.
- 6.Follow Up Persistently: Call weekly to check on the status. Keep detailed notes of every interaction.
- 7.Escalate If Necessary: If unresolved after 30-60 days, file complaints with state insurance department, state medical board, or federal agencies.
