Plan Types & Coverage Implications

Your BCBS Michigan plan type affects how you access CF specialists and get Trikafta prescribed:

HMO Plans (Blue Care Network)

  • Referral required: You must get a referral from your primary care physician to see a pulmonologist or CF specialist
  • Without a proper referral, you'll pay full costs for specialist visits
  • The specialist can then prescribe Trikafta and submit the required prior authorization

PPO Plans

  • No referral needed: You can directly schedule with any in-network CF specialist
  • Stay in-network to minimize out-of-pocket costs
  • Prior authorization is still required regardless of plan type
Tip: If you're on an HMO, call your PCP today to request a referral to a CF specialist. This can take a few days to process.

Formulary Status & Tier Placement

Trikafta is classified as a specialty medication on BCBS Michigan's formulary, meaning:

  • Specialty (SP) tier placement: Higher cost-sharing than standard medications
  • Not available at retail pharmacies: Must be dispensed through designated specialty pharmacies
  • Prior authorization always required: No exceptions for any plan type

Alternative CFTR Modulators on the formulary include Kalydeco (ivacaftor) and Symdeko (tezacaftor/ivacaftor), which may be preferred options depending on your specific CFTR mutations.

Prior Authorization Requirements

BCBS Michigan's PA criteria for Trikafta are strict and must be submitted by a licensed healthcare provider through Availity Essentials.

Required Documentation

Essential Clinical Information:

  • CFTR genotype test results: Laboratory report showing eligible mutations (typically at least one F508del mutation)
  • CF specialist prescription: Must be prescribed by a clinician specializing in cystic fibrosis care
  • Diagnosis confirmation: ICD-10 codes for cystic fibrosis
  • Prior treatment history: Documentation of previous CF therapies, including duration, outcomes, and reasons for discontinuation

Step Therapy Considerations: Historically, BCBS Michigan required trials of other CFTR modulators (like Kalydeco or Symdeko) before approving Trikafta. Your provider should document:

  • Previous CFTR modulator use and clinical response
  • Reasons for switching (lack of efficacy, intolerance, contraindications)
  • Medical justification for Trikafta specifically

Submission Process

  1. Provider logs into Availity Essentials with their registered credentials
  2. Completes the prior authorization form with all required clinical data
  3. Uploads supporting documentation (genetic test results, clinical notes, prior therapy records)
  4. Submits electronically through the portal
  5. BCBS reviews typically within 5-10 business days

Specialty Pharmacy Network

Critical: Trikafta can only be dispensed through BCBS Michigan's designated specialty pharmacy network.

From our advocates: We've seen cases where patients initially denied for "insufficient documentation" were approved on appeal after their CF specialist provided a detailed medical necessity letter citing specific CFTR modulator guidelines. The key was showing how Trikafta's triple-combination mechanism addressed the patient's specific genetic profile better than previous therapies.

FAQ

How long does BCBS Michigan prior authorization take? Typically 5-10 business days for standard review. Expedited reviews (when medically urgent) are completed within 72 hours.

What if Trikafta isn't on my formulary? Submit a formulary exception request with your CF specialist's medical necessity letter. Include documentation of failed alternatives and clinical rationale.

Can I appeal if I live in Michigan but have coverage from another state's Blue plan? Appeal rights depend on where your policy is issued, not where you live. Check with your specific Blue plan for their appeal process and timelines.

Does step therapy apply if I failed CFTR modulators outside Michigan? Yes, documented treatment failures from any location count toward step therapy requirements. Ensure your provider includes complete medication history.

What happens if Walgreens Specialty can't fill my prescription? Contact BCBS Pharmacy Customer Service immediately. They may authorize use of Accredo or another in-network specialty pharmacy as an exception.
