Disputing Medical Claims: Know Your Rights

04.30.26 12:00 AM - By Motion Connected

Receiving a medical claim denial can feel overwhelming, especially when you were expecting your insurance to cover the service. The good news? Denials can sometimes be corrected or overturned with the right steps. Understanding how to dispute a medical claim can help you avoid unnecessary out-of-pocket expenses and ensure your benefits are applied correctly.

What Does It Mean to Dispute a Medical Claim?

Disputing a medical claim (also called filing an appeal) is the process of asking your insurance company to review and reconsider a decision they’ve made about a claim. This typically happens when a service is denied, applied incorrectly to your deductible, or paid at a lower level than expected.


Before starting an appeal, review your Explanation of Benefits (EOB). This document explains how the claim was processed and provides a reason for the denial or reduced payment. Sometimes the issue is as simple as missing information or a coding error.


Common Reasons Claims Are Denied

    • Services were deemed not medically necessary
    • Prior authorization was not obtained
    • The provider was out-of-network
    • Incorrect billing codes were submitted
    • Coverage had lapsed at the time of service


Understanding the reason is the first step in deciding how to move forward. Once you’ve determined the denial reasoning, the next step is to dispute (appeal) the decision. 

How to Dispute a Medical Claim

  • 1. Contact Your Insurance Carrier

  • Call the member services number on your insurance ID card or the contact information listed on the denial notification. Ask for clarification on the denial and confirm what documentation may be required to appeal.


  • 2. Speak with Your Provider’s Office
    Sometimes the provider can resubmit the claim with corrected coding or additional information. Many billing offices are experienced in handling these situations. 


  • 3. Gather Supporting Documentation
    This may include medical records, a letter of medical necessity from your doctor, or prior authorization approvals.


    • 4. Submit a Formal Appeal
    Follow your insurer’s appeal process exactly as outlined in your plan documents. Be mindful of deadlines - appeals often must be filed within a specific timeframe.

    5. Follow Up
    Keep copies of everything you submit and document phone calls, including dates and representative names. If you don’t receive a response within the stated review period, call to check on the status.

    If your internal appeal is denied, you may have the right to request an external review by an independent third party. While the process can take time, claim disputes can be successfully resolved when members advocate for themselves and provide thorough documentation.
