Step-by-step in Texas
- Read the denial notice. The reason code drives your evidence and the appeal deadline is on the letter.
- File the internal appeal with your insurer within the plan's window (typically 180 days for ERISA/ACA plans; expedited turnaround 72 hours for urgent cases).
- Attach medical necessity evidence that maps to the exact denial reason: guideline citations, chart notes, prior-therapy documentation, peer-reviewed literature.
- Optional: file a complaint with Texas Department of Insurance at www.tdi.texas.gov/. A DOI complaint runs in parallel — it does not replace the internal appeal.
- Request external review within 4 months of the final internal denial. In Texas, external review is administered by Texas Department of Insurance. The IRO decision is binding on the insurer.
Texas program notes
Texas administers Independent Review Organization (IRO) review through TDI under Tex. Ins. Code Chapter 4202. Requests are filed with the insurer and forwarded to a TDI-assigned IRO.
How long do I have to appeal in Texas?+
Typically 180 days from the denial notice for ERISA/ACA plans to file an internal appeal, and 4 months from the final internal denial to request external review (45 CFR § 147.136(d)(2)(ii)).
Can I file a complaint against my insurer with the Texas Department of Insurance?+
Yes, at https://www.tdi.texas.gov/. Consumer complaints can prompt market-conduct review, but binding relief on a specific claim comes from internal appeal plus external review.
Who decides external review in Texas?+
An Independent Review Organization certified by Texas Department of Insurance, with a physician reviewer in the relevant specialty.
What if my case is urgent?+
Request an expedited appeal. Insurers must decide within 72 hours if delay would jeopardize life, health, or ability to regain maximum function.
What federal law protects appeal rights?+
29 CFR § 2560.503-1 (ERISA claim procedure) for employer plans; 45 CFR § 147.136 (ACA internal appeal + external review) for all non-grandfathered commercial plans.
