How to Appeal a Denied Insurance Claim in Texas

Texas passed one of the first comprehensive surprise billing laws in the country — SB 1264, effective September 2019 — well before the federal No Surprises Act. If your health insurance claim was denied in Texas, you have strong protections under both state and federal law.

This guide covers the specific Texas appeal process, surprise bill protections, and the agencies that can help you — on top of the federal appeal rights every American has under the ACA.

Texas SB 1264: Surprise Bill Protections

Who Is Protected

• Patients with state-regulated plans — individual, small group, and large group plans
• HMO and PPO members
• Important: Self-funded employer plans (where your employer pays claims directly instead of buying insurance) may NOT be covered by Texas state law. These plans are regulated by federal law (ERISA) instead. Check your plan documents or ask HR.

Protected Situations

1. Emergency care at any facility — regardless of whether the hospital or provider is in your network
2. Out-of-network provider at an in-network facility — when you had no choice or didn't receive the required disclosures before the service

Your Responsibility

In a protected situation, you only owe your in-network cost-sharing (copay, coinsurance, or deductible amount). The rest is resolved between the provider and insurer through Texas's mediation and arbitration process — you are not involved.

How to Appeal a Denied Claim in Texas

Step 1: Understand the Denial

Your denial letter must include the specific reason for the denial, the clinical criteria used, and instructions for how to appeal. Note the claim number and appeal deadline.

Step 2: File an Internal Appeal

File with your insurer using the instructions in the denial letter. Include:

• A clear statement that you are appealing
• Your member ID and claim number
• A letter from your doctor explaining why the treatment is medically necessary
• Supporting medical records and documentation

Texas requires insurers to respond to internal appeals within 30 days for pre-service claims and 60 days for post-service claims. Urgent cases must be handled within 72 hours.

Step 3: Request an Independent Review

If your internal appeal is denied, Texas law gives you the right to an independent review organization (IRO) review. This is similar to the federal external review but administered by the Texas Department of Insurance (TDI).

• The IRO is an independent third party with no financial ties to your insurer
• The review is free to you
• You can request an IRO review for medical necessity denials, experimental treatment denials, and other coverage disputes
• The IRO's decision is binding on the insurer

Step 4: Contact TDI

If you believe your insurer is violating Texas law — including surprise billing protections — contact the Texas Department of Insurance:

• Phone: 1-800-252-3439
• Online: tdi.texas.gov
• Filing deadline for surprise bill complaints: 90 days from receiving the bill

If You Receive a Surprise Bill in Texas

If you receive an out-of-network bill for emergency care or from a provider you didn't choose at an in-network facility:

1. Don't pay it yet. You have time to investigate.
2. Check if SB 1264 applies — was it an emergency, or were you treated by a provider you didn't choose at an in-network facility?
3. Call your insurer and tell them the bill should be processed under Texas surprise billing protections. You should only owe your in-network cost-sharing.
4. Contact TDI if the provider or insurer doesn't cooperate. File a complaint within 90 days.

Self-Funded Plans: A Critical Distinction

Texas SB 1264 does not apply to self-funded employer plans. These plans are regulated by federal law (ERISA), not state law. If you have a self-funded plan, you're still protected by the federal No Surprises Act, which provides similar protections for emergencies and out-of-network providers at in-network facilities.

How to check: Your Summary of Benefits and Coverage (SBC) or plan documents will say whether the plan is "fully insured" (state law applies) or "self-funded" / "self-insured" (federal law applies). You can also ask your HR department.

The Bottom Line

Texas was ahead of the curve on surprise billing with SB 1264, and the state's independent review process gives you a free, binding appeal when your insurer denies care. Between state and federal protections, Texas residents have strong tools to fight back against unfair denials — but you need to know which law applies to your specific plan.
