Quick Answer
In Texas, employer plans must give you at least 180 days after you receive a denial to file an internal appeal (29 CFR 2560.503-1(h)(3)(i)), and individual and marketplace plans must follow the same rule (45 CFR 147.136(b)(3)); Medicare and Medicaid set their own deadlines, and the deadline in your denial letter controls. If a utilization review agent denies your appeal, you can seek review by an independent review organization (IRO) (Tex. Ins. Code § 4201.401(a)); a standard IRO determination is due by the earlier of the 15th day after the IRO receives the information it needs or the 20th day after it receives the request (§ 4202.003(2)), and the agent must comply with it (§ 4201.401(b)). File complaints with TDI at 800-252-3439. AppealArmor drafts your appeal letter from your denial, free, and its Next Steps sheet tells you where to send it and how to reach the state regulator.

Filing a Complaint
You can file a complaint with the Texas Department of Insurance. AppealArmor does not write a complaint letter. When your plan is state-regulated, the Next Steps sheet in your appeal packet lists the Texas regulator's website, phone number and complaint page, so you can file a complaint yourself.
Texas law your appeal letter can cite
Where Texas law applies to your plan, AppealArmor can cite the provision in your letter, quoting it or summarising it, with its citation. Code picks the provision from the list below, not a model, and only from the official source linked on each one. A provision is used only when your plan is one it covers: state insurance law generally does not reach self-funded employer plans, Medicare or Medicaid. If you are not sure whether your employer plan is self-funded, the provision goes on your Next Steps sheet instead of into the letter. The Next Steps sheet also explains each law used, in plain words.

Review by independent review organization
Tex. Ins. Code § 4201.401(a)
A utilization review agent shall allow any party whose appeal of an adverse determination is denied by the agent to seek review of that determination by an independent review organization assigned to the appeal in accordance with Chapter 4202.
When your letter uses it: Your plan is an individual plan, or an employer plan you confirm is fully insured (not self-funded). It does not depend on the reason for the denial.

Tex. Ins. Code § 1369.0546(b)
A prescribing provider on behalf of a patient may submit to the patient's health benefit plan issuer a written request for an exception to a step therapy protocol required by the patient's health benefit plan.
When your letter uses it: Your plan is an individual plan, or an employer plan you confirm is fully insured (not self-funded). The denial reason you confirm is about step therapy (for example it says step therapy or fail first, or that you must try another drug first).

If your appeal is denied, you can seek review by an independent review organization (Tex. Ins. Code § 4201.401(a)). The utilization review agent must comply with the determination of the independent review organization (§ 4201.401(b)).
Texas Appeal Process Timeline
Texas Insurance Code Chapters 4201 and 4202 set these timelines for utilization review appeals and independent review, and the federal claims rules also apply.
Internal Appeal
30 days responseA utilization review agent must give written notice of its appeal decision as soon as practicable, and not later than the 30th calendar day after it receives the appeal (Tex. Ins. Code § 4201.359(a)). You have 180 days from the denial to file (federal rule, 29 CFR 2560.503-1).
External IRO Review
15-20 days decisionAn independent review organization must make its determination by the earlier of the 15th day after it receives the information it needs or the 20th day after it receives the request; the deadline is shorter for a life-threatening condition (Tex. Ins. Code § 4202.003). The utilization review agent must comply with the determination (§ 4201.401(b)).
Expedited Review
1 working dayFor an expedited appeal of a denial of emergency care, continued hospitalization, or another service that the provider states in writing is necessary to treat a life-threatening condition or prevent serious harm, resolution may not exceed one working day from the date all information necessary to complete the appeal is received (Tex. Ins. Code § 4201.357). Under the federal claims rules, an urgent-care appeal decision is due within 72 hours.
Common Denial Types in Texas
These are common reasons for a denial. AppealArmor tailors your appeal to the specific denial reason. Below is what Texas law says about each.
Medical Necessity Denials
If a utilization review agent denies your appeal, the notice must state the clinical basis for the denial, the specialty of the physician or other health care provider who made it, and your right to independent review (Tex. Ins. Code § 4201.359(b)). The agent must follow the independent review organization's determination on medical necessity (§ 4201.401(b)).
Prior Authorization Denials
Texas HB 3459 (2021), as amended by HB 3812 (2025) bars an HMO or insurer that uses preauthorization from requiring it for a particular service from a physician or provider whose requests for that service were approved at least 90 percent of the time in the one-year evaluation period, and the provider provided the service at least five times (Tex. Ins. Code § 4201.653).
Out-of-Network Denials
Texas SB 1264 (2019) is an act relating to consumer protections against certain medical and health care billing by certain out-of-network providers. It applies to services provided on or after January 1, 2020.
Frequently Asked Questions
How long do I have to appeal a health insurance denial in Texas?
In Texas, you generally have 180 days from the date of the denial notice to file an internal appeal. Under the federal claims rules, an appeal decision for urgent care is due within 72 hours. After exhausting internal appeals, you can request an external independent review.
How do I file a complaint with the Texas Department of Insurance?
You can file a complaint online at the Texas Department of Insurance website, by phone at 800-252-3439, or by mail to 1601 Congress Avenue, Austin, TX 78701. AppealArmor does not write a complaint letter; when your plan is state-regulated, the Next Steps sheet in your appeal packet lists the regulator's contact details and complaint page.
What is external review in Texas?
External review is an independent review of your insurer's denial by a third-party organization not affiliated with your insurance company. In Texas, a standard IRO determination is due by the earlier of the 15th day after the IRO receives the information it needs or the 20th day after it receives the request (Tex. Ins. Code § 4202.003(2)), and the utilization review agent must comply with it (§ 4201.401(b)). This means if the independent reviewer overturns the denial, your insurer must comply.
What state laws protect me from insurance denials in Texas?
Key Texas insurance laws include: IRO Review (Tex. Ins. Code § 4201.401(a)) — a denied appeal can go to an independent review organization; Notice of Appeal Decision (Tex. Ins. Code § 4201.359) — written notice within 30 calendar days of the appeal, with the clinical basis for any denial; Prior Authorization Exemption (HB 3459 (2021), as amended by HB 3812 (2025); Tex. Ins. Code § 4201.653) — an HMO or insurer that uses preauthorization may not require a physician or provider to get preauthorization for a particular service if, in the most recent one-year evaluation period, it approved or would have approved at least 90 percent of that provider's requests for that service and the provider provided the service at least five times. These laws establish your appeal rights and set standards insurers must follow. Your appeal letter cites only the provisions listed under "Texas law your appeal letter can cite".
Does AppealArmor work for Texas insurance denials?
Yes. AppealArmor reads your denial letter, asks you to confirm every detail, and drafts an appeal letter that cites the federal appeal rules for your type of plan. For Texas it can also cite Texas law, quoting the provision or summarising it: Tex. Ins. Code § 4201.401(a) and Tex. Ins. Code § 1369.0546(b). Texas law goes into your letter only where it applies to your plan: state insurance law generally covers individual plans and fully insured employer plans, not self-funded employer plans, Medicare or Medicaid; a provision listed for step-therapy denials is used only when your denial is about step therapy. AppealArmor does not cite case law and does not write a complaint letter; when your plan is state-regulated, the Next Steps sheet lists Texas Department of Insurance's website, phone number and complaint page. It's free and needs no account.
