How to File Insurance Complaint in Texas
Learn how to file an insurance complaint with the Texas Department of Insurance (TDI) online, by phone, or by mail — and how Texas's external review process works.
When a Texas insurer denies your health insurance claim, you don't have to accept the decision. The Texas Department of Insurance (TDI) is the state agency responsible for regulating health insurance companies and protecting consumers. Filing a complaint with TDI can put pressure on your insurer, trigger a formal review, and sometimes result in a reversed denial.
About TDI: Texas Department of Insurance
Website: tdi.texas.gov Consumer Help Line: 1-800-252-3439 Hours: Monday–Friday, 8 a.m.–5 p.m. CT
TDI licenses insurance companies doing business in Texas, investigates consumer complaints, and enforces the Texas Insurance Code. The Consumer Protection Division is specifically dedicated to helping Texans resolve disputes with their insurers.
What TDI Regulates — And What It Doesn't
TDI oversees fully-insured health plans — meaning plans where the insurance company bears the financial risk. This includes individual plans, small group employer plans, and some large group fully-insured plans.
TDI cannot regulate self-funded ERISA plans. If your employer is large and self-insures its health benefits (paying claims directly using company funds), your plan falls under federal ERISA jurisdiction, not Texas state law. Your HR department or your Summary Plan Description (SPD) can confirm which type of plan you have.

TDI will review the insurer's response and determine whether it complied with Texas law and the terms of your policy. If TDI finds a violation, it can:
- Order the insurer to reconsider the claim
- Require payment
- Refer the case for enforcement action and potential fines
You'll receive a written determination from TDI explaining the outcome. The typical complaint resolution timeline is 30–45 days for standard cases.
Texas's Gold Card Law: Fewer Prior Auth Hurdles
Texas has a notable consumer protection called the Gold Card Law (Texas Insurance Code Section 4201.655). This law allows physicians who have demonstrated a high approval rate for prior authorizations to receive a "gold card" exemption — meaning the insurer cannot require prior authorization for services those physicians have historically provided without denials.
If your physician qualifies for a gold card exemption and your insurer still required prior authorization and denied your claim, that may be a violation worth raising specifically in your complaint.
External Independent Review: Complete Guide" class="auto-link">External Review in Texas
If TDI's complaint process doesn't resolve your issue — or if you want an independent medical opinion on a medical necessity denial — Texas offers an external review process.
Under the ACA and Texas law, you have the right to request an external review by an IROs) Explained" class="auto-link">Independent Review Organization (IRO) after exhausting your insurer's internal appeals process. Key details:

- Turnaround: Standard reviews within 45 days; expedited (urgent) reviews within 72 hours
- Cost: Free to you

Texas HMO Complaint Process
If you're in a Texas HMO plan, TDI handles complaints under the Texas HMO Act. HMO members also have the right to a specialist referral and to access emergency care without prior authorization. If your HMO violated these rights, TDI can investigate.
Tips for a Strong Complaint
- Get your denial in writing: If your claim was denied verbally or by phone, request the denial in writing before filing a complaint.
- Attach medical necessity documentation: A letter from your treating physician explaining why the service was medically necessary significantly strengthens your case.
- Reference your policy: Quote the specific coverage provision your insurer allegedly violated.
- Track all communications: Keep a log of every call, email, and letter — dates, names, and outcomes.
- File while appealing: You can file with TDI simultaneously with your internal insurer appeal. These processes are independent.
