Claim Appeals

Only charges denied because the service is not covered by TRICARE or not medically necessary may be appealed. Your TRICARE Explanation of Benefits (EOB) or provider remittance will indicate if a denied charge is appealable. If the denial note does not indicate the charge can be appealed, you may request a claim review instead of an appeal.

Note: Only Point of Service (POS) charges for emergency care can be appealed. Visit our Disputing Point of Service Charges page to review other scenarios for disputing POS charges.

Who can appeal a denied claim?

  • TRICARE beneficiary (or parent of a minor), 
  • Legal guardian of the beneficiary,
  • A non-network provider (if he or she performed the service and accepted assignment on the claim),
  • A network provider (if appealing a claim on his/her own behalf and the denied claim is appealable per the remittance notice) (Note: Network providers cannot bill patients for non-covered services or services denied as not medically necessary.),
  • Legally appointed representatives (appeals submitted by anyone other than the above will not be accepted unless he or she has been appointed as a representative by power of attorney or by submitting an Appointment of Representative for an Appeal form), or
  • An attorney, if acting on behalf of an appropriate appealing party.
