Why Texas State Rules Matter

Texas insurance laws provide strong patient protections that work alongside your Blue Cross Blue Shield of Texas (BCBSTX) plan policies. Understanding both gives you the best chance of getting Nourianz approved.

Key Texas Protections:

  • 180-day appeal window for commercial plans
  • Step therapy override rights under Texas Insurance Code §1369.0546
  • Independent external review through Texas Department of Insurance
  • Expedited review for urgent cases (72 hours for PA, 5 days for external review)
Note: Self-funded employer plans (ERISA) follow federal rules instead of Texas state protections, but many offer similar timelines and processes.

Step Therapy Protections

Texas Insurance Code §1369.0546 gives you the right to override step therapy requirements when medically appropriate.

Exception Criteria

  1. Contraindication - Required step therapy drug would cause harm or adverse reaction

  3. Clinical Inappropriateness - Step therapy would worsen a comorbid condition or reduce daily function

Documentation Requirements

Submit a written request on the standard form prescribed by the Texas Insurance Commissioner with supporting clinical evidence:

  • Medical records showing contraindications or prior failures
  • Lab results or imaging if relevant
  • Guidelines supporting Nourianz as appropriate therapy
  • Provider attestation of medical necessity
Tip: If BCBSTX doesn't respond to your step therapy exception request within 72 hours, it's automatically approved under Texas law.
