For Texas health-insurance denials
State · Texas · appeal letter

How to appeal a denied claim in Texas.

Texas is the second-largest insured state, and the appeal-rights framework here has its own scaffolding — the Texas Department of Insurance (TDI) complaint pathway under Texas Insurance Code Chapter 21 § 21.58A, the 28 Tex. Admin. Code § 3.1010 external review (IRO) window for fully-insured TX plans, and the federal ERISA § 503 procedure at 29 C.F.R. § 2560.503-1 for self-funded employer plans operating in Texas. A Texas ADVERSE BENEFIT DETERMINATION carries the same EOB reason codes a denial in any other state would — “medical necessity not established,” “not a covered benefit,” “precertification not obtained,” “step-therapy criteria not satisfied,” “out-of-network provider” — but the appeal frameworks that attach are Texas-specific, the agency that intervenes is the TDI Consumer Help Line (1-800-252-3439, tdi.texas.gov), and the timelines are a 30-day internal appeal under § 21.58A(b), a 4-month external review (IRO) deadline under 28 Tex. Admin. Code § 3.1010, and a 5-day TDI response window for expedited complaints under § 21.58A(c). Self-funded employer plans under the federal ERISA § 503 procedure at 29 C.F.R. § 2560.503-1 still apply, with TDI procedural constraints layering on aspects the federal rule does not preempt.

01 · What this segment looks like

A Texas health-insurance denial — and the appeal frameworks that apply to it.

The Texas denial segment captures a specific configuration: the member holds a fully-insured TDI-licensed plan issued in Texas, or a Blue Cross and Blue Shield of Texas fully-insured product, and has received an Adverse Benefit Determination on the EOB. The denial reason will track the carrier's internal reason code (medical necessity, prior authorization, step therapy, formulary exclusion, out-of-network), but the appeal frameworks that attach are Texas-specific. The Texas Department of Insurance (TDI) regulates carriers under Texas Insurance Code Chapter 21 (the Texas Insurance Code), with § 21.58A spelling out the carrier's adverse-determination complaint pathway, the 30-day internal-appeal window, and the 4-month external review (IRO) deadline maintained by TDI's published IRO list. The TDI Consumer Help Line is the front door for Texas members — 1-800-252-3439, online complaint form at tdi.texas.gov — and the published IRO list governs the external-review step once the internal appeal is exhausted.

TDI-licensed carriers operating in Texas — Aetna, Blue Cross and Blue Shield of Texas, Cigna, Humana, UnitedHealthcare — are subject to Texas Insurance Code Chapter 21 § 21.58A, which layers on top of any federal regime: a 30-day internal-appeal window after the ABD under § 21.58A(b) tied to the TDI complaint mechanism, a 4-month external review (IRO) deadline from the final internal denial under 28 Tex. Admin. Code § 3.1010 (the TDI-maintained IRO list), and the 5-day TDI response window for expedited complaints under § 21.58A(c) — a parallel channel to the federal 72-hour urgent-claim framing in ERISA § 503 for self-funded employer plans. The TDI complaint pathway runs in parallel with the federal 4-month ACA external review window at 45 C.F.R. § 147.136(d) for ACA marketplace plans, and the most protective of the two carries the day.

Self-funded ERISA plans — the typical larger-employer group plan where the employer pays the claims rather than buying insurance from a carrier — fall outside the TDI complaint pathway and outside 28 Tex. Admin. Code § 3.1010, and run through the federal ERISA § 503 claims-procedure rule at 29 C.F.R. § 2560.503-1, with the parallel 4-month external-review channel under 29 C.F.R. § 2590.715-2719 for non-grandfathered plans. Texas UR laws (28 Tex. Admin. Code § 3.1010 et seq.) still apply to procedural aspects the federal rule does not preempt — clinical-criteria disclosure, peer-reviewer escalation, language-access requirements — but the appeals timeline and the right-to-file-a-civil-action follow fully from 29 C.F.R. § 2560.503-1 and ERISA § 502(a) at 29 U.S.C. § 1132(a)(1)(B). A well-built Texas appeal letter cites both: the controlling TX statute (§ 21.58A for TDI-licensed plans) or the federal preemption fallback (29 C.F.R. § 2560.503-1 for self-funded ERISA), and the right federal framework underneath.

01 · TX-specific timelines

01

30-day internal-appeal window

After an Adverse Benefit Determination on a TDI-licensed Texas plan, the enrollee has 30 days from receipt of the ABD notice to file a first-stage internal appeal with the carrier — Tex. Ins. Code § 21.58A(b) sets the carrier's internal-appeal deadline and the right to escalate to a TDI complaint on exhaustion. The carrier has 30 days to issue a decision for standard appeals, and the 5-day TDI response window under § 21.58A(c) attaches for expedited complaints where ongoing care is at stake. For non-TDI self-funded ERISA plans, 29 C.F.R. § 2560.503-1(h)(3)(i) supplies the parallel federal 30-day window keyed to the ABD notice.

02

4-month external review (IRO) window

After exhausting the carrier's internal appeal, the enrollee has 4 months from the final internal denial to file an Independent Review Organization (IRO) request with the TDI — under 28 Tex. Admin. Code § 3.1010, with the IRO list maintained by TDI. The IRO's decision is binding on the carrier: when the IRO physician reviewer overturns the denial, the carrier must comply. The TDI Consumer Help Line at 1-800-252-3439 and tdi.texas.gov are the front door for both the initial complaint and the IRO request — and the typical complaint-to-IRO cycle runs 30 to 45 calendar days for non-expedited reviews.

03

5-day TDI expedited

Where a delay would seriously jeopardize the enrollee's life, health, or ability to regain maximum function, the expedited channels collapse to the 5-day TDI response window under § 21.58A(c) for TDI-licensed TX plans, or to 72 hours under the federal ERISA § 503 urgent-claim framing at 29 C.F.R. § 2560.503-1(f)(2) for self-funded TX employer plans. For ACA marketplace plans, the federal 72-hour urgent external-review window at 45 C.F.R. § 147.136(e)(3) attaches on the second-stage level. The appeal letter should frame the request as a continuation of an established clinical plan, not a new request, to put the expedited window on the table.

01 · The three TX-specific denial shapes we see most

The timelines and review rights that apply on a Texas denial.

  • 01

    BCBS Texas imaging-precertification denial

    A Blue Cross and Blue Shield of Texas enrollee whose plan denied an MRI or imaging precertification on “medical necessity not established” or “precertification not obtained” grounds. BCBS Texas is TDI-licensed for its fully-insured TX products under Texas Insurance Code Chapter 21 — the appeal routes through the BCBS member portal and the published appeals fax, then escalates to a TDI complaint at 1-800-252-3439 or tdi.texas.gov, then reaches external review (IRO) within 4 months under 28 Tex. Admin. Code § 3.1010. The appeal cites § 21.58A(b) for the 30-day internal-appeal window and TAS § 21.58A(c) for the parallel expedited channel where imaging delay would jeopardize care.

  • 02

    Blue Cross Texas medical-necessity denial

    A Blue Cross and Blue Shield of Texas enrollee whose carrier denied a service on “medical necessity not established,” “experimental / investigational,” or “not a covered benefit” grounds. BCBS Texas is TDI-licensed for fully-insured TX products. The 30-day internal appeal under § 21.58A(b) runs through the BCBS member portal, then escalates to a TDI complaint and external review (IRO) under 28 Tex. Admin. Code § 3.1010 within 4 months of the final internal denial. Self-funded ERISA plans through BCBS fall under 29 C.F.R. § 2560.503-1 with the parallel federal 4-month external-review window at 29 C.F.R. § 2590.715-2719.

  • 03

    UnitedHealthcare Texas ACA step-therapy denial

    A UnitedHealthcare Texas enrollee whose carrier denied a pharmacy step-therapy exception on a biologic or specialty drug. UHC operates both TDI-licensed fully-insured TX products and self-funded ERISA employer plans in Texas. The denial routes through the myuhc.com member portal / ACA-mandated fax, then escalates through § 21.58A(b) for fully-insured TDI-licensed plans, or 29 C.F.R. § 2560.503-1 for self-funded ERISA. For ACA marketplace plans, the federal 4-month external-review channel under 45 C.F.R. § 147.136(d) attaches on the second-stage level.
