What Affects Kalydeco Approval Timing

Several factors influence how quickly UnitedHealthcare processes your Kalydeco prior authorization in Michigan:

Benefit Type Impact:

  • Commercial plans: Standard 3-14 day review period
  • Medicare Advantage: Similar timeline with potential for automated approval if criteria clearly met
  • Medicaid/Healthy Michigan Plan: Up to 14 calendar days per state regulations

Documentation Completeness: The biggest factor affecting timing is having complete genetic testing documentation. UnitedHealthcare requires proof of a CFTR mutation responsive to ivacaftor as listed in FDA labeling.

Complexity Factors:

  • Clear-cut FDA-approved mutations: Fastest processing
  • Novel or rare mutations: May require additional clinical review
  • Missing genetic test results: Automatic delay for additional information
Note: Unlike some specialty drugs, Kalydeco doesn't require step therapy through other CFTR modulators if your mutation is ivacaftor-responsive, which can significantly speed approval.

Where to Find Your Genetic Testing:

  • CF care center records
  • Original diagnostic workup
  • Previous insurance approvals
  • Newborn screening follow-up

Verification Steps:

  1. Confirm your mutation appears on the FDA-approved list in Kalydeco labeling
  2. Ensure genetic test was performed by an FDA-cleared assay
  3. Verify CF diagnosis is clearly documented in medical records

Submission to Initial Review (1-5 Days)

Time-Saving Tips

Portal Optimization:

Documentation Bundling:

  • Provide mutation-specific rationale upfront
  • Attach relevant FDA labeling sections

Direct Specialty Routing:

  • Request review by pulmonologist or geneticist if available
  • Use peer-to-peer review for complex cases
  • Leverage CF care center relationships
From our advocates: "We've seen Kalydeco approvals turn around in 24 hours when the genetic testing clearly shows an FDA-approved responsive mutation and the submission includes all required clinical documentation upfront. The key is having your CF care team prepare a complete package before the first submission rather than responding to information requests later."
