Answer Box: Renewing Tagrisso Coverage with Cigna

Cigna requires annual renewal of prior authorization for Tagrisso (osimertinib) in California. Start the renewal process 4-6 weeks before your current authorization expires. You'll need updated EGFR mutation documentation, current oncologist assessment showing treatment benefit, and recent imaging/labs. Submit through Cigna's provider portal or designated fax. If denied, California's Independent Medical Review (IMR) through DMHC offers strong appeal rights with high success rates for oncology drugs.

If Coverage Lapses: Bridge Options

Immediate Actions

If your authorization expires before renewal approval:

  1. Contact your specialty pharmacy about emergency supplies
  2. Call Cigna member services to check status and request expedited review
  3. Ask your oncologist about AstraZeneca patient assistance programs
  4. Document all communications for potential appeals

AstraZeneca Support Programs

While awaiting approval, explore manufacturer assistance:

  • AZ&Me Prescription Savings Program for eligible patients

Contact AstraZeneca patient support directly through their official channels for current eligibility requirements.

Treatment Interruption Considerations

Per FDA labeling, Tagrisso can be safely held for up to 3 weeks if necessary. However, avoid interruptions when possible, as there are no established bridging therapies for EGFR-mutant NSCLC.

Annual Formulary Changes

2025 Cigna Updates

Tagrisso remains on Cigna's formulary but continues to require prior authorization and is placed on Tier 4 (Specialty Tier), resulting in higher patient cost-sharing.

What to Re-verify Annually

  • Formulary status and tier placement
  • Prior authorization requirements and criteria changes
  • Quantity limits or step therapy requirements
  • Preferred specialty pharmacy networks
  • Copay or coinsurance amounts
Tip: Cigna can implement mid-year formulary changes with written notice, so stay alert for communications about your medications.

FAQ

How long does Cigna take to process Tagrisso renewals? Standard renewals are processed within 72 hours of receiving complete documentation. Expedited requests must be decided within 24 hours.

What if my EGFR mutation testing is old? Cigna typically accepts initial mutation testing from diagnosis. However, if there's been disease progression, newer testing may be required to confirm continued EGFR-driven disease.

Can I appeal if Cigna requires step therapy? Yes. California law allows step therapy exceptions if you've previously failed or are intolerant to required first-line treatments, or if they're contraindicated.

What happens if I miss the renewal deadline? Contact Cigna immediately to request expedited processing. You may need to restart the prior authorization process, but emergency supplies may be available through manufacturer programs.

Does Tagrisso require specialty pharmacy dispensing? Most Cigna plans require Tagrisso to be filled through Express Scripts/Accredo or other designated specialty pharmacies for coverage.

How often do California IMRs overturn Tagrisso denials? While specific statistics for Tagrisso aren't published, DMHC reports show high overturn rates for oncology drug denials when proper clinical evidence is provided.

From our advocates: We've seen many Tagrisso renewals initially denied for "insufficient documentation of ongoing benefit," only to be quickly approved once the oncologist provided a brief update letter with recent scan results and functional status. The key is being proactive and thorough with clinical evidence rather than assuming the previous approval automatically continues.
