Indication Requirements: What Counts as Medical Necessity

BCBS Illinois follows FDA labeling for Kalydeco coverage. Your case must demonstrate:

Core Requirements

  • Confirmed cystic fibrosis diagnosis with appropriate ICD-10 code (E84.x)
  • CFTR genetic testing showing an ivacaftor-responsive mutation
  • Age-appropriate dosing per FDA label
  • CF specialist involvement (pulmonologist or CF center physician)

FDA-Approved Mutations

Kalydeco is approved for patients with CF who have specific CFTR mutations including:

  • Gating mutations (G551D and others listed in current FDA label)
  • R117H mutation (with specific residual function criteria)
  • Other mutations as updated in FDA labeling
Tip: Always reference the current FDA prescribing information when documenting mutation status, as the approved list is periodically updated.

Step Therapy & Exceptions

Good news: Kalydeco typically does not require step therapy for patients with appropriate CFTR mutations. Current BCBS Illinois formularies show PA and quantity limits but no step therapy (ST) designation.

However, some employer plans may add step therapy requirements. If step therapy is unexpectedly required:

Exception Pathways

  1. Medical contraindication to step drugs
  2. Previous trial and failure of required medications
  3. Drug interactions or allergies
  4. Clinical inappropriateness based on mutation-specific therapy

Document any previous CFTR modulator use (Trikafta, Orkambi, Symdeko) and outcomes to strengthen your case.

Quantity Limits and Dosing Requirements

Standard quantity limits align with FDA dosing:

Age-Based Dosing

  • ≥6 years: 150 mg twice daily (60 tablets/30 days)
  • 6 months to <6 years: Weight-based dosing (60 packets/30 days)
  • 1-6 months: Age/weight-specific dosing

Reduced Dosing Situations

Quantity limits may be adjusted for:

  • Moderate/severe hepatic impairment: Once daily dosing
  • Strong CYP3A inhibitors: Twice weekly dosing
  • Moderate CYP3A inhibitors: Once daily dosing

Document any dose reductions with clinical rationale to ensure appropriate quantity approval.

Required Diagnostics and Documentation

Essential Documentation Package

Genetic Testing

  • Complete CFTR mutation analysis showing both alleles
  • Laboratory report confirming ivacaftor-responsive mutation
  • Statement that mutation is FDA-approved for Kalydeco

Clinical Assessment

  • Baseline pulmonary function (FEV₁ % predicted)
  • Sweat chloride test results (if available)
  • Current CF therapies and adherence
  • Exacerbation history and hospitalizations

Prescriber Credentials

  • Board certification in pulmonology or pediatric pulmonology
  • CF center affiliation (preferred)
  • Statement of ongoing CF specialist care

Monitoring Plan

Include your plan for:

  • Liver function monitoring (baseline and periodic)
  • Pulmonary function follow-up
  • Clinical response assessment
  • Adverse event monitoring

Specialty Pharmacy Requirements

BCBS Illinois requires Kalydeco to be dispensed through designated specialty pharmacies for ongoing fills. Common networks include:

  • CVS Specialty
  • Accredo
  • AllianceRx Walgreens Prime

Patient Process

  1. Initial fill: May be available at retail pharmacy with PA approval
  2. Ongoing fills: Must transfer to specialty pharmacy
  3. Coordination: Specialty pharmacy handles insurance billing and patient support

The specialty pharmacy will typically contact your office for clinical information and coordinate refills directly with the patient.

Evidence to Support Medical Necessity

Guidelines to Reference

  • FDA prescribing information for ivacaftor
  • Cystic Fibrosis Foundation care guidelines
  • European Medicines Agency (EMA) guidance if applicable
  • Peer-reviewed literature on mutation-specific outcomes

Effective Documentation Strategy

Frame your request around established standards of care:

"Patient has cystic fibrosis with [specific mutation] documented by genetic testing. This mutation is responsive to ivacaftor per current FDA labeling. Kalydeco is indicated as standard of care for this genotype per CF Foundation guidelines and is expected to improve lung function and reduce exacerbations based on clinical trial data."

Sample Medical Necessity Narrative

Clinician Corner: Medical Necessity Template

"[Patient name] is a [age]-year-old with cystic fibrosis confirmed by [sweat test/genetic testing]. CFTR genotype analysis reveals [specific mutations], with [responsive mutation] being FDA-approved for ivacaftor therapy. Current FEV₁ is [value]% predicted with [clinical status]. Previous therapies include [list]. Kalydeco is medically necessary as mutation-directed therapy expected to improve lung function, reduce exacerbations, and slow disease progression per published efficacy data and CF Foundation recommendations. Alternative CFTR modulators are [not appropriate/contraindicated/previously failed] because [rationale]. Patient will be monitored with quarterly visits, pulmonary function testing, and liver function surveillance per standard protocols."

Appeals Process in Illinois

Illinois provides robust appeal rights under the Health Carrier External Review Act.

Timeline and Process

Internal Appeal

  • Deadline: File within timeframe specified in denial letter (typically 180 days)
  • Decision: 15 business days for pre-service, 30 days for post-service
  • Expedited: 24-48 hours for urgent situations

External Review

When to Use Expedited Appeals

Request expedited review if delay would:

  • Seriously jeopardize life or health
  • Jeopardize ability to regain maximum function
  • Subject patient to severe pain

For CF patients, document how delayed Kalydeco access could worsen lung function or increase exacerbation risk.

Common Denial Reasons & Solutions

Denial Reason Solution Documentation Needed
"Not FDA-approved for mutation" Provide current FDA label showing approved mutations Updated prescribing information, genetic report
"Experimental/investigational" Cite FDA approval and CF guidelines FDA approval letter, clinical guidelines
"Lack of specialist involvement" Document CF center care Specialist letter, clinic notes
"Insufficient prior therapy" Clarify mutation-specific indication Genetic counselor letter, mutation database
"Quantity exceeds limit" Justify dosing frequency Prescribing information, clinical rationale

FAQ

How long does BCBS Illinois PA take? Standard PA decisions are typically made within 72 hours to 15 business days. Expedited reviews for urgent cases can be completed within 24-48 hours.

What if Kalydeco is non-formulary on my plan? Request a formulary exception with your PA submission. Document medical necessity and lack of appropriate alternatives on formulary.

Can I appeal if I'm denied for the wrong mutation? Yes. Provide updated genetic testing and current FDA labeling showing your mutation is approved. Consider genetic counselor consultation letter.

Does step therapy apply if I've used other CFTR modulators? Previous CFTR modulator use may actually support your case if you can document inadequate response or intolerance to other agents.

What's the difference between internal and external appeals? Internal appeals are reviewed by your insurance company. External appeals are reviewed by independent physicians through the Illinois Department of Insurance and are binding on the insurer.

How do I know if my plan requires specialty pharmacy? Check your formulary or call member services. Most BCBS plans require specialty pharmacy for ongoing Kalydeco fills after initial approval.

Can I get emergency supplies while waiting for PA? Ask your prescriber about emergency supplies or samples. Some plans allow temporary fills pending PA approval.

What if my CF center is out of network? Document medical necessity for specialist care and request single-case agreement or out-of-network exception for continued care.
