  • Portal: MyPrime.com or BCBSTX provider portal

4. Include Medical Necessity Letter

  • Who: CF specialist (preferred) or prescribing physician
  • What: Detailed letter explaining why Kalydeco is medically necessary for your specific genotype
  • Key elements: Diagnosis, CFTR mutation(s), why alternatives aren't appropriate, expected benefits
  • Timeline: Can be prepared while waiting for PA decision

5. Coordinate Specialty Pharmacy

  • Who: You or your clinic
  • What: Contact Accredo (BCBSTX's preferred specialty pharmacy) at 833-721-1619

When Alternatives Make Sense

Before pursuing a formulary exception or appeal, consider whether other CFTR modulators might be appropriate for your situation. Alternatives may make sense when:

  • Trikafta is available and covered: Most patients with at least one F508del mutation are eligible for Trikafta, which is often preferred on formularies and clinically superior to Kalydeco for many genotypes
  • Age restrictions apply: Some CFTR modulators have different age approvals
  • Tolerability concerns exist: If you've had adverse reactions to Kalydeco previously
  • Formulary tier differences: Alternative may have lower cost-sharing
Important: Never switch medications without discussing with your CF care team. Each CFTR modulator works differently based on your specific genetic mutations.

Typical CFTR Modulator Alternatives

Understanding the landscape of CFTR modulators can help you and your doctor make informed decisions about coverage strategies:

Trikafta (elexacaftor/tezacaftor/ivacaftor)

  • Eligibility: Age 2+ with at least one F508del mutation or certain other mutations
  • Coverage: Generally broad formulary coverage due to superior efficacy
  • Considerations: Most effective option for eligible patients; often first-line therapy

Symdeko (tezacaftor/ivacaftor)

  • Eligibility: Age 12+ with specific mutation combinations
  • Coverage: Limited; most eligible patients also qualify for Trikafta
  • Considerations: Patients typically transition to Trikafta for better outcomes

Orkambi (lumacaftor/ivacaftor)

  • Eligibility: Age 1+ with two F508del mutations
  • Coverage: Variable; often requires PA
  • Considerations: Eligible patients usually also qualify for Trikafta
From our advocates: We've seen families successfully transition from Kalydeco to Trikafta when genetic testing revealed an F508del mutation that wasn't initially identified. The key was working with the CF center to retest and document the complete genotype, which opened up better coverage options.

Exception Strategy for Non-Formulary Cases

If Kalydeco isn't on your specific BCBSTX formulary or if alternatives aren't medically appropriate, you'll need a formulary exception. Here's the strategy:

Build Your Medical Case

  • Document why covered alternatives won't work (contraindications, prior failures, genetic incompatibility)
  • Get a strong letter from your CF specialist explaining the medical necessity
  • Include peer-reviewed literature supporting Kalydeco for your specific mutation
  • Reference FDA labeling that supports your genotype

Submit Through Proper Channels

Follow Up Strategically

  • Track submission through provider portal
  • Be prepared to provide additional information quickly
  • Consider peer-to-peer review if initial exception is denied
