Renewal Triggers: When to Start the Process

Start 30-45 days early. Cigna's specialty drug approvals typically last 12 months, but your specific authorization letter will include the exact expiration date. Don't wait for a denial notice—proactive renewal prevents treatment gaps.

Signs you should start immediately:

  • Authorization expires within 6 weeks
  • You've had any changes in dosing frequency (every 2 vs. 4 weeks)
  • New insurance plan year is approaching (January 1st for most)
  • You've experienced breakthrough attacks requiring on-demand therapy
Tip: Set a calendar reminder 60 days before your authorization expires. Specialty pharmacies like Accredo often send renewal reminders, but don't rely solely on them.

Evidence Update: What Cigna Needs to See

Cigna's reauthorization criteria focus on beneficial response to therapy. Document these key metrics:

Response to Therapy

  • Attack frequency reduction: Compare pre-treatment vs. current attack rates
  • Severity improvement: Document any decrease in attack intensity or duration
  • Quality of life measures: Work/school attendance, reduced emergency visits

Adherence Documentation

  • Injection logs: Keep records of dates, doses, and any missed injections
  • Pharmacy records: Accredo or your specialty pharmacy can provide fill history
  • Provider visits: Regular follow-ups with your allergist/immunologist

Adverse Events

  • Document any side effects experienced
  • Note how they were managed
  • Confirm continued tolerability
Note: The 2020 HAEA guidelines recommend reviewing preventive treatment at least annually, which aligns with Cigna's renewal requirements.

Renewal Packet: Must-Include Documentation

Your prescriber should submit a complete renewal packet including:

Required Clinical Documentation

  • Updated prescription from allergist/immunologist
  • Attack diary or log showing frequency/severity over the past 12 months
  • Treatment response summary with specific metrics
  • Confirmation of HAE diagnosis (C1-INH levels, C4 levels if not previously submitted)

Letter of Medical Necessity Structure

  1. Patient identification and confirmed HAE Type I or II diagnosis
  2. Treatment history including pre-Takhzyro attack frequency
  3. Current response with specific attack reduction data
  4. Continued medical necessity with clinical rationale
  5. Specialist oversight confirmation

Supporting Evidence

  • Recent lab work (if clinically indicated)
  • Emergency department visits for HAE attacks
  • Use of on-demand medications (icatibant, C1-INH)

Timeline: Submission to Decision

Step Timeline Action Required
Submission 30-45 days before expiration Provider submits renewal packet
Initial Review 5-14 business days Cigna reviews documentation
Decision Up to 30 days total Approval, denial, or request for additional info
Appeal (if needed) Within 180 days of denial Submit internal appeal

Important: If Cigna requests additional information, respond within their specified timeframe (typically 14 days) to avoid automatic denial.

If Coverage Lapses: Bridge Therapy Options

If your Takhzyro renewal is delayed or denied, discuss these FDA-approved alternatives with your HAE specialist:

Long-Term Prophylaxis Options

  • Haegarda (C1-INH subcutaneous): Self-administered twice weekly
  • Orladeyo (berotralstat): Once-daily oral medication
  • Cinryze (C1-INH IV): Administered twice weekly
  • Andembry (garadacimab): Monthly subcutaneous injection

Emergency Medication Access

Critical: Maintain on-demand therapy regardless of prophylaxis status:

  • Firazyr (icatibant): Self-administered subcutaneous autoinjector
  • Berinert (C1-INH): IV administration for acute attacks
  • Ekterly (sebetralstat): First oral on-demand treatment (ages 12+)

Counterforce Health specializes in turning insurance denials into targeted appeals, helping patients navigate complex prior authorization requirements and bridge therapy coordination during coverage gaps.

Internal Appeals (Cigna)

  • Timeline: 180 days from denial notice

  • Required: Denial letter, medical records, prescriber support letter

External Review (Michigan DIFS)

  • Timeline: 127 days after final internal denial

From our advocates: We've seen Michigan external reviews frequently overturn Cigna denials for rare disease medications when proper clinical evidence is submitted. The key is demonstrating clear medical necessity and providing comprehensive attack documentation—something many initial submissions lack.

FAQ

How long does Cigna prior authorization renewal take? Standard reviews take up to 30 days. Expedited reviews (72 hours) are available for urgent medical situations with physician documentation.

What if Takhzyro becomes non-formulary? You can request a formulary exception with clinical justification. Michigan law requires insurers to have exception processes for medically necessary non-covered drugs.

Can I request expedited renewal if my authorization is expiring? Yes, if your physician documents that a treatment gap would cause serious health consequences. Submit urgency documentation with your renewal.

Does step therapy apply to Takhzyro renewals? Generally no for renewals if you've demonstrated response. However, verify your specific plan's policies haven't changed for the new year.

What counts as "beneficial response" for renewal? Cigna looks for decreased HAE attack frequency or severity compared to pre-treatment baseline. Even modest improvements can support renewal.
