Texas Insurance Appeal Rights Overview
Texas has one of the nation's strongest surprise billing laws (SB 1264/TIC 1467) and a well-established Independent Review Organization (IRO) process. Texas is the largest state without Medicaid expansion, making the IRO process especially important for commercially insured consumers. The state's large and diverse market has many carrier options in metropolitan areas. Texas was also a pioneer in independent review legislation.
All Texas residents with non-grandfathered health plans have appeal rights under the ACA, including the right to internal appeal and external review. Texas may provide additional protections beyond federal requirements. Self-insured employer plans (ERISA plans) are subject to federal rather than state regulations for most purposes, though the ACA external review requirements apply to all non-grandfathered plans.

Internal Appeal Deadlines in Texas
You must file your internal appeal within 180 days from the denial notice, consistent with ACA requirements. Do not miss this deadline — it may forfeit your right to appeal entirely. The insurer must respond within 30 days for standard appeals; 72 hours for urgent/expedited appeals.
To file your internal appeal, send a written appeal to the address listed on your denial notice (or Explanation of Benefits). Include your denial letter, a letter explaining why the denial should be overturned, relevant medical records, a letter of medical necessity from your treating physician, and any supporting documentation such as clinical guidelines or peer-reviewed research. Send everything by certified mail with return receipt, or use the insurer's online portal if available with delivery confirmation.
If your medical situation is urgent — meaning that waiting for a standard appeal decision could seriously jeopardize your life, health, or ability to regain maximum function — request an expedited appeal. Expedited appeals must be decided within 72 hours. Your physician may need to certify the urgency.
External Review Process in Texas
Texas has a state-administered external review process. After exhausting internal appeals, consumers can request an external review through the Texas Department of Insurance. Decisions by the independent review organization are binding on the insurer.
To request external review in Texas, file your request with the Texas Department of Insurance after receiving your final internal appeal denial. Include a copy of the internal appeal denial, all documentation you submitted with your internal appeal, and any additional evidence or arguments. The external reviewer will evaluate your case independently and issue a binding decision.
External review is particularly valuable because the independent reviewer applies clinical evidence and medical guidelines rather than the insurer's internal criteria. In many states, external review overturns a significant percentage of denials.
