Why Texas State Rules Matter

Texas insurance law provides strong protections for patients needing specialty drugs like Symdeko (tezacaftor/ivacaftor), but these protections vary by plan type. If you have a state-regulated commercial plan (look for "TDI" or "DOI" on your insurance card), you're covered by Texas step therapy override laws and Independent Review Organization appeals.

However, Humana's large presence in Texas is primarily through Medicare Advantage plans, which follow federal Medicare rules rather than state protections. This means your appeal rights and timelines depend on whether you have:

  • Humana Medicare Advantage: Federal Medicare appeals process (65 days to appeal, standard/expedited options)
  • Humana commercial plan: Texas state protections apply (180 days to appeal, IRO review available)
Note: Self-funded employer plans (ERISA) are exempt from both state and Medicare protections, following their own internal policies.

Prior Authorization Turnaround Standards

Humana Medicare Advantage Timeline

For Medicare Advantage plans, Humana must respond to prior authorization requests within:

  • Standard requests: 14 days for Part D drugs
  • Expedited requests: 72 hours when delay would jeopardize health

Texas State-Regulated Plans

For commercial plans regulated by Texas, prior authorization decisions must be made within 24 hours for prescription drugs, including specialty pharmaceuticals like Symdeko. This applies to both routine and urgent requests.

Actionable tip: Submit PA requests at least 5 business days before the desired start date. If Humana doesn't respond within the required timeframe, the request may be deemed approved by default under Texas law.

Step Therapy Protections in Texas

Texas Insurance Code requires health plans to grant step therapy overrides when specific medical criteria are met. For Symdeko, common override situations include:

Override Criteria

A step therapy protocol override must be granted if your prescribing provider documents that:

  • Contraindication: The required first-line drug is contraindicated or likely to cause adverse reactions
  • Previous failure: You've already tried and failed the step therapy drug or experienced significant adverse effects
  • Ineffectiveness: The required drug is expected to be ineffective based on your medical history
  • Treatment delay concern: The step therapy requirement would delay effective treatment or affect your ability to maintain adherence

Filing Process

  • Use the Commissioner's standard form (verify current form with your insurer)
  • Urgent requests: 24-hour response required
  • Non-urgent requests: 72-hour response required
  • Default approval: If the insurer fails to respond within the required timeframe
Clinician Corner: When submitting step therapy override requests, clearly cite the applicable Texas Insurance Code criteria and provide supporting clinical documentation. Include specific details about previous CFTR modulator trials, genetic testing results showing eligible mutations, and why Symdeko is clinically appropriate for this patient's specific genotype.

Continuity of Care Provisions

Texas law provides specific protections for patients with life-threatening conditions like cystic fibrosis during insurance transitions:

90-Day Extension Rule

If your CF specialist is terminated from Humana's network, Texas law mandates a 90-day extension of service at in-network rates for patients with life-threatening illnesses. This gives you time to:

  • Transition care to a new in-network provider
  • Complete ongoing treatment cycles
  • Maintain medication continuity

Children with Special Health Care Needs (CSHCN) Program

Texas offers a state program specifically for CF patients that provides coverage for:

  • Medical services and specialty drugs
  • Case management
  • Therapies and equipment

This program can serve as a safety net during insurance gaps or coverage disputes. Contact the program at the number listed in the "When to Escalate" section below.

External Review & Complaints Process

Medicare Advantage Appeals (Most Humana Plans)

  1. Internal appeal: File within 65 days of denial
  2. Independent Review Entity (IRE): Automatic if internal appeal denied
  3. Administrative Law Judge: For claims over $200 (2025 threshold)

Texas State IRO Process (Commercial Plans)

For state-regulated plans, Texas offers Independent Review Organization appeals:

  1. Complete internal appeal first (required in most cases)
  2. File IRO request using form LHL009 within 4 months of final denial
  3. Expedited review: 72 hours for urgent cases, 20 days for standard
  4. Binding decision: If IRO approves, Humana must comply

Contact for IRO questions: 1-866-554-4926 (option 2) or [email protected]

FAQ

Q: How long does Humana prior authorization take in Texas? A: For Medicare Advantage plans, 14 days standard or 72 hours expedited. For state-regulated commercial plans, Texas requires 24-hour decisions for prescription drugs.

Q: What if Symdeko isn't on my Humana formulary? A: Request a formulary exception with clinical documentation explaining why covered alternatives aren't appropriate for your specific CF genotype and medical history.

Q: Can I get an expedited appeal if I'm already taking Symdeko? A: Yes, if discontinuing therapy would jeopardize your health. Document clinical stability on current therapy and risks of interruption.

Q: Do Texas step therapy protections apply to my Humana Medicare plan? A: No, Medicare plans follow federal rules. However, Medicare has its own coverage determination and appeals processes that may achieve similar outcomes.

Q: What's the difference between internal and external appeals? A: Internal appeals are reviewed by your insurance company. External appeals (IRO for state plans, IRE for Medicare) are reviewed by independent organizations and are often more favorable to patients.

Q: How much does Symdeko cost without insurance? A: The wholesale acquisition cost is approximately $323,491 annually. Vertex offers patient assistance programs—check their website or call 1-877-752-5933.

Q: Can my doctor request a peer-to-peer review? A: Yes, most insurers including Humana offer peer-to-peer reviews where your doctor can speak directly with the plan's medical director about the denial.

Q: What happens if I lose my appeal? A: For state-regulated plans, you can request Independent Review Organization review. For Medicare plans, you can proceed to the Independent Review Entity and potentially Administrative Law Judge levels.

The appeals process for specialty drugs like Symdeko can be complex, but Texas provides strong patient protections and multiple avenues for challenging denials. Counterforce Health specializes in navigating these processes, helping ensure that clinical evidence and regulatory requirements are properly presented to maximize approval chances.
