Plan Types & Coverage Implications

California has two distinct Blue Cross Blue Shield entities with different policies:

Blue Shield of California covers roughly 4 million members through HMO, PPO, and Medicare Advantage plans regulated primarily by the California Department of Managed Health Care (DMHC). These plans follow California's robust consumer protection laws and Independent Medical Review (IMR) process.

Anthem Blue Cross operates separately in California with different formularies and prior authorization criteria. Check your insurance card carefully—the company name determines which forms and appeal processes apply.

Note: Self-funded employer plans may use Blue Cross Blue Shield networks but follow ERISA rules rather than California insurance regulations, affecting your appeal rights.

Formulary Status & Tier Placement

Blue Shield of California

Tagrisso appears on Blue Shield's Specialty Drug List for the Plus Drug Formulary, placing it on a specialty tier with higher cost-sharing requirements. This designation means:

  • Prior authorization required for all uses
  • Specialty pharmacy dispensing mandatory
  • Higher member cost-sharing (typically 20-40% coinsurance)

Coverage Requirements

Blue Shield maintains a specific osimertinib (Tagrisso) medication policy requiring:

  • Confirmed NSCLC diagnosis with appropriate staging
  • Documented EGFR mutation (exon 19 deletion, L858R, or other activating mutations)
  • Appropriate clinical setting (metastatic, adjuvant, or CNS disease as per FDA/NCCN guidelines)

Prior Authorization Requirements

Clinical Documentation Needed

Requirement Documentation Source
EGFR Mutation Molecular pathology report with specific mutation type Blue Shield Policy
NSCLC Diagnosis Pathology report with ICD-10 codes Plan requirements
Disease Stage Imaging reports, staging documentation Clinical necessity
Prior Therapies Treatment history, response/intolerance records If applicable
Performance Status ECOG score, functional assessment Clinical context

Step Therapy Considerations

Current Blue Shield documents do not list Tagrisso under specific step therapy requirements for first-line EGFR-mutated NSCLC. However, plans may require documentation of why alternative EGFR TKIs (erlotinib, gefitinib, afatinib) are inappropriate if they're designated as preferred agents.

Specialty Pharmacy Requirements

Blue Shield requires Tagrisso to be dispensed through contracted specialty pharmacies. This means:

  • Retail pharmacy rejection of Tagrisso prescriptions
  • Specialty pharmacy enrollment required before first fill
  • Coordination of benefits and prior authorization handled by the specialty pharmacy

Contact Blue Shield member services to identify your plan's preferred specialty pharmacy partners and initiate the enrollment process.

Submission Process & Forms

Electronic Prior Authorization (Preferred)

CoverMyMeds Integration: Blue Shield accepts electronic prior authorizations through CoverMyMeds. Select "Blue Shield of California" and complete the osimertinib-specific workflow.

Provider Portal (AuthAccel): Providers can submit requests through Blue Shield's online authorization system after secure login.

Fax Submission

If electronic submission isn't available:

Required Information

Your prior authorization request must include:

  • Patient demographics and Blue Shield member ID
  • Prescriber information (NPI, specialty, contact details)
  • Drug details (Tagrisso, strength, dosing, quantity)
  • Clinical documentation package (see table above)
  • Medical necessity rationale with guideline citations

Appeals Process in California

Internal Appeal (First Step)

If your Tagrisso request is denied, file an internal appeal with Blue Shield within the timeframe specified in your denial letter (typically 30-180 days for commercial plans).

For Blue Shield of California members:

  • Submit through the grievance process
  • Include enhanced clinical documentation
  • Request expedited review if treatment delay poses immediate health risks
  • Decision timeline: 30 days standard, 72 hours expedited

Independent Medical Review (IMR)

California's IMR system provides powerful appeal rights for medical necessity denials:

Eligibility: Available for denials based on medical necessity, experimental/investigational determinations, or emergency services disputes.

Process:

  1. Complete internal appeal first (with exceptions for urgent/experimental cases)
  2. File IMR application through DMHC within 6 months of final denial
  3. Submit comprehensive medical records and guideline citations
  4. Independent physician experts review the case

Timeline: 30-45 days standard, 7 days or less for urgent cases

Cost: Free to patients

Success Factors: IMR frequently overturns denials for guideline-supported cancer treatments like Tagrisso when proper documentation is provided.

From our advocates: We've seen strong IMR outcomes for Tagrisso cases that include detailed oncologist letters citing specific NCCN guideline recommendations and explaining why treatment delays risk disease progression. The key is demonstrating that Tagrisso represents standard-of-care therapy for the patient's specific EGFR mutation and disease stage.

Cost Considerations

Member Cost-Sharing

As a specialty tier medication, Tagrisso typically requires coinsurance rather than a flat copay. This can result in significant out-of-pocket costs, often $1,000-$3,000+ monthly depending on your plan's cost-sharing structure.

Financial Assistance Options

AstraZeneca Support: The manufacturer offers patient assistance programs for eligible individuals. Contact AstraZeneca directly or ask your specialty pharmacy to screen for available programs.

Foundation Support: Organizations like the Lung Cancer Foundation of America and CancerCare provide grants for cancer medication copays.

State Programs: California residents may qualify for additional assistance through state-sponsored programs.

Common Approval Strategies

Strengthen Your Medical Necessity Case

Guideline Citations: Reference specific NCCN guideline recommendations for your EGFR mutation type and disease stage. Osimertinib is Category 1 (preferred) for many first-line EGFR-mutated NSCLC scenarios.

Clinical Urgency: Document progression risk, CNS involvement, or other factors that make treatment delays dangerous.

Alternative Inadequacy: If step therapy is required, explain clinical contraindications to older EGFR TKIs (inferior CNS penetration, resistance patterns, survival outcomes).

Documentation Quality

Ensure your molecular pathology report clearly states:

  • Specimen source and adequacy
  • Testing methodology
  • Specific EGFR mutation identified
  • Date of testing

Missing or ambiguous biomarker documentation is a frequent cause of denial.

What if Tagrisso is non-formulary on my plan? Request a formulary exception with medical necessity documentation. If denied, appeal through internal process then IMR, emphasizing guideline support and lack of therapeutic alternatives.

Can I request an expedited appeal? Yes, if treatment delay poses an immediate and serious threat to your health. Your oncologist must document the urgency in clinical terms.

Does step therapy apply if I've failed EGFR TKIs outside California? Prior treatment history from other states should be accepted. Include complete medical records showing previous therapy trials and outcomes.

What's the difference between Blue Shield of California and Anthem Blue Cross? They're separate companies with different policies. Blue Shield of California uses the forms and processes outlined above. Anthem Blue Cross requires different submission portals and forms.

How much does Tagrisso cost with Blue Cross Blue Shield? Specialty tier coinsurance typically ranges from 20-40% of the drug cost. Monthly out-of-pocket expenses often exceed $1,000-$3,000 without additional assistance programs.

Can I use any specialty pharmacy? No, you must use a Blue Shield-contracted specialty pharmacy. Contact member services to identify approved options and initiate enrollment.

What happens if my appeal is denied? For California-regulated plans, request Independent Medical Review (IMR) through DMHC. IMR decisions are binding on the plan and frequently overturn denials for guideline-supported treatments.
