Texas Medical Fee Dispute Resolution Request is a process that allows patients to resolve disputes between healthcare providers and insurance companies regarding the payment of medical services. This process is handled by the Texas Department of Insurance (TDI), and involves submitting a formal dispute resolution request to the TDI. The TDI will then review the dispute and make a determination whether an adjustment should be made to the medical service payments. There are two types of Texas Medical Fee Dispute Resolution Requests: Prepayment Dispute Resolution Request and Post-payment Dispute Resolution Request. Prepayment Dispute Resolution Request is used when an insurance company denies a medical service claim, and the patient believes the denial is incorrect. Post-payment Dispute Resolution Request is used when an insurance company has paid less than the amount requested for medical services.
