Coverage Basics

Is Ruconest Covered by Aetna CVS Health?

Ruconest is covered by Aetna CVS Health plans for the treatment of acute hereditary angioedema (HAE) attacks in adults and adolescents. However, it requires prior authorization across all Aetna lines of business, including commercial plans, Medicare Advantage, and Aetna Better Health of Michigan (Medicaid).

Which Plans Require Prior Authorization?

All Aetna CVS Health plans in Michigan require prior authorization for Ruconest:

  • Commercial/employer plans
  • Individual marketplace plans
  • Medicare Advantage plans
  • Aetna Better Health of Michigan (Medicaid)
  • Medicare-Medicaid Plans (MMP)

The drug is typically managed through CVS Specialty Pharmacy due to its complex storage and administration requirements.

Prior Authorization Process

Step-by-Step: Fastest Path to Approval

1. Verify Patient Coverage (1-2 days)

  • Call the number on patient's Aetna member ID card
  • Confirm Ruconest requires PA and identify the correct submission process
  • Check if patient needs CVS Specialty Pharmacy specifically

2. Gather Required Documentation (2-3 days)

  • Lab results: C1-INH antigenic and functional levels
  • Genetic testing (if HAE with normal C1-INH)
  • Attack history and frequency documentation
  • Prior treatment failures or contraindications

3. Complete Aetna's Ruconest Form (Same day)

4. Submit via Preferred Channel (Same day)

  • Fax: 1-888-267-3277 (most common)
  • Phone notification: 1-866-752-7021
  • Electronic: Availity provider portal where available

5. Track and Follow Up (Ongoing)

  • Standard review: 30-45 days
  • Expedited review: 24-72 hours (with medical urgency)
  • Call Aetna if no response within expected timeframe

Clinical Requirements

HAE Diagnosis Documentation

Aetna requires confirmed hereditary angioedema diagnosis with specific lab criteria:

For HAE with C1-INH Deficiency (Type I/II):

  • Low C1-INH antigenic level below laboratory normal range, OR
  • Normal C1-INH antigenic level with low functional C1-INH (<50% or below lab normal)
  • Low C4 levels on two separate occasions

For HAE with Normal C1-INH:

  • Normal C1-INH levels AND documented mutation in:
    • F12, angiopoietin-1, plasminogen, kininogen-1 (KNG1), HS3ST6, or MYOF genes
  • OR both of the following:
    • Angioedema refractory to high-dose antihistamine therapy (e.g., cetirizine 40 mg/day) for ≥1 month
    • Family history of angioedema

Attack Documentation Requirements

Your medical records must demonstrate:

  • Frequency and severity of acute HAE attacks
  • Attack locations (laryngeal, abdominal, peripheral)
  • Emergency interventions needed (ER visits, hospitalizations)
  • Impact on daily activities and quality of life
Clinician Corner: Include specific attack dates, symptoms, treatments used, and outcomes in your medical necessity letter. Aetna reviewers look for objective evidence that attacks are frequent enough to warrant on-demand therapy but not severe enough to require prophylaxis.

Timing and Urgency

Standard Review Timeline

  • Submission to decision: 30-45 days
  • Additional information requests: Add 10-15 days
  • Peer-to-peer review: Available if initial review is unfavorable

Expedited Reviews

For urgent medical situations, Aetna offers expedited review:

  • Commercial plans: 72 hours
  • Medicare plans: 72 hours
  • Medicaid (Aetna Better Health MI): 24-72 hours

Criteria for expedited review:

  • Patient experiencing active HAE attack
  • Delay would seriously jeopardize patient's health
  • Physician attestation of medical urgency required

Common Denial Reasons

Denial Reason How to Overturn Required Documentation
Insufficient HAE diagnosis Submit complete lab workup C1-INH levels, C4, genetic testing
Use for prophylaxis Clarify acute treatment indication Letter confirming on-demand use only
Missing attack documentation Provide detailed attack history ER records, physician notes, attack log
Non-formulary status Request medical exception Evidence of medical necessity
Step therapy not met Document contraindications/failures Prior therapy records, intolerance notes

Most Effective Appeal Strategies

  1. Reference Aetna's own policy criteria in your appeal letter
  2. Include FDA labeling supporting Ruconest use for acute HAE
  3. Provide specialist letter from allergist/immunologist
  4. Submit objective evidence of attack frequency and severity

Appeals Process in Michigan

Internal Appeals (First Level)

Who can appeal: Patient, authorized representative, or prescriber Deadline: 180 days from denial notice Timeline: 30 days for standard; 72 hours for expedited

How to submit:

  • Online: Aetna member portal
  • Phone: 1-855-582-2025
  • Fax: 1-855-330-1716
  • Mail: Aetna PA, 1300 E. Campbell Rd., Richardson, TX 75081

External Review (Michigan DIFS)

If Aetna's internal appeal is denied, Michigan patients have strong external review rights under the Patient's Right to Independent Review Act.

Key Michigan advantages:

  • 127 days to file external review (longer than federal 120-day standard)
  • 60 days maximum for standard external review decision
  • 72 hours for expedited external review with physician letter
  • Binding decisions - if Independent Review Organization (IRO) approves, Aetna must comply

How to file with DIFS:

Michigan Advantage: DIFS is very consumer-oriented and will assign your case to an IRO with HAE expertise. The external review is conducted by independent medical experts, not Aetna employees.

Frequently Asked Questions

How long does Aetna CVS Health PA take in Michigan? Standard review takes 30-45 days. Expedited review (for urgent medical needs) takes 24-72 hours. Michigan doesn't have state-specific PA timelines that differ from Aetna's national standards.

What if Ruconest is non-formulary on my plan? Request a formulary exception by demonstrating medical necessity. Include documentation that preferred alternatives (like icatibant or Berinert) are contraindicated or have failed.

Can I request an expedited appeal in Michigan? Yes. Both Aetna internal appeals and Michigan DIFS external reviews offer expedited options (72 hours) when delay would jeopardize patient health. Requires physician letter supporting urgency.

Does step therapy apply if I've failed treatments outside Michigan? Yes, Aetna accepts prior therapy documentation from any state. Include complete records of medications tried, dates, outcomes, and reasons for discontinuation.

What's the difference between medical and pharmacy benefit coverage? Ruconest is typically covered under pharmacy benefit (CVS Caremark) for most Aetna plans. Medicare Part B may cover it under medical benefit for buy-and-bill scenarios. Check your specific plan.

How do I know if my appeal was successful? Aetna will send written notice of PA decisions. For external reviews, Michigan DIFS sends decisions to both patient and insurer. Approved appeals result in immediate coverage authorization.

When insurance denials seem overwhelming, remember that Counterforce Health specializes in turning these challenges into successful appeals.
