Your Legal Rights in Texas

Federal Protections That Apply to All Texas Residents

ACA §2719 (Affordable Care Act) requires non-grandfathered health plans to provide at least one internal appeal and access to external independent review. Aetna's denial must specify the reason, the clinical criteria applied, and your appeal rights.

ERISA §1133 (Employee Retirement Income Security Act) governs employer-sponsored self-funded plans. Under ERISA §1133, Aetna must provide written notice of the denial reason, allow access to your complete claims file, and provide a full and fair review. ERISA §502(a) allows a federal civil action if the appeal fails.

MHPAEA §1185a (Mental Health Parity and Addiction Equity Act) requires equal coverage for mental health and substance use disorder services. Texas Insurance Code §1355.015 adds state parity requirements. If a behavioral health claim was denied, request a comparative analysis comparing Aetna's review criteria for your claim versus comparable medical claims.

Key Texas-specific protections:

Texas Independent Review Organization (IRO) Program — Texas IROs overturn approximately 50% of reviewed denials. After exhausting Aetna's internal appeal, you can request IRO review through TDI. The IRO's decision is binding on Aetna and free to you. Texas maintains a registry of certified IROs.

Texas Insurance Code §1301.053 — Requires Aetna's medical necessity determinations to be made by licensed physicians in the appropriate specialty. If a non-physician or out-of-specialty reviewer issued the denial, this is a violation you can raise in your appeal.

Texas Insurance Code §4201.302 — Requires Aetna to issue utilization review decisions within strict timeframes: prospective reviews within 3 business days; concurrent reviews within 1 business day; retrospective reviews within 30 days. Missed deadlines can result in deemed approval.

Texas Insurance Code §1369.0546 (Step Therapy) — Requires Aetna to provide a step therapy exception process. Aetna must respond to exception requests within 72 hours for urgent cases and 5 business days for non-urgent requests.

Texas Prompt Pay Law — Aetna must pay clean claims within 45 days for clean paper claims and 30 days for electronic claims. Late payment triggers automatic interest penalties.

Texas Independent Dispute Resolution (IDR) — For out-of-network billing disputes at in-network facilities, Texas's IDR process applies under Texas Insurance Code §1467.

For ERISA self-funded plans, federal external review applies.

Internal appeal deadline: 180 days from the date of Aetna's denial letter.

Step-by-Step: How to Appeal Your Aetna Denial in Texas

Step 1: Read and Analyze the Denial Letter

Under ACA §2719 and Texas Insurance Code, Aetna's denial letter must specify the reason for denial, the clinical criteria applied, and your appeal rights. Read every line. Note all stated denial reasons and identify the applicable Texas Insurance Code sections.

Request your complete claims file from Aetna. Specifically request confirmation that a licensed physician in the appropriate specialty issued the utilization review decision, as required by Texas Insurance Code §1301.053.

Step 2: Build a Strong Documentation Package

Before writing the appeal, assemble:

• Full denial letter with all denial codes
• Medical records for the denied treatment
• Treating physician's letter of medical necessity (detailed, signed, dated, on letterhead)
• Lab results, imaging, and specialist consultation notes
• Aetna's Clinical Policy Bulletin for the denied service
• Clinical practice guidelines from the relevant specialty society
• Confirmation of the reviewer's specialty credentials under Texas Insurance Code §1301.053
• Records of prior failed treatments if step therapy was cited; exception documentation under Texas Insurance Code §1369.0546
• Out-of-network billing documentation under Texas Insurance Code §1467 if applicable
• Parity analysis for behavioral health denials
• Prior authorization records including submission timestamps and Aetna's response dates

Step 3: Write a Targeted Appeal Letter

Your appeal letter must address every denial reason with specific evidence. Include your Aetna member ID, claim number, date of service, and denial date. Cite ACA §2719, ERISA §1133 (for employer plans), MHPAEA §1185a and Texas Insurance Code §1355.015 (for behavioral health denials), Texas Insurance Code §1301.053 (physician reviewer requirement), Texas Insurance Code §4201.302 (utilization review timeliness), and Texas Insurance Code §1369.0546 (step therapy exception if applicable). State the precise outcome you are requesting and set a deadline for Aetna's response.

Step 4: Request Peer-to-Peer Review

Ask your treating physician to request a peer-to-peer review with the Aetna medical director. Texas Insurance Code requires Aetna to facilitate this process. Your doctor can present the clinical specifics of your case — including why the applicable Clinical Policy Bulletin criteria are met — directly to the reviewer. This step resolves a significant number of Texas Aetna denials before IRO review.

Step 5: Submit the Appeal

• Send via certified mail with return receipt to the address on the denial letter
• Also submit through the Aetna member portal at aetna.com
• Keep copies of all materials with timestamps
• Aetna must respond within required Texas Insurance Code §4201.302 timeframes; check whether Aetna's previous utilization review response was timely — a missed deadline may constitute a deemed approval

Step 6: Request TDI IRO Review If the Internal Appeal Fails

If Aetna upholds the denial, immediately request IRO review through the Texas Department of Insurance. Contact TDI at tdi.texas.gov or call (800) 252-3439. Texas's IRO program is one of the most active in the country, with an overturn rate of approximately 50%. The IRO's decision is binding on Aetna and free to you.

File a TDI regulatory complaint if Aetna violated Texas Insurance Code §4201.302 timeliness requirements, used a reviewer who lacked the required specialty credentials, failed to follow step therapy exception procedures, or violated prompt pay requirements.

Step 7: Legal Action for High-Value Claims

For large claims, consult an insurance appeal attorney in Texas. ERISA §502(a) allows federal civil actions for employer plan members. Texas recognizes bad faith insurance claims for unreasonable denial conduct under the Texas Insurance Code's unfair claims practices provisions.
