Why Myths About Emgality Coverage Persist

Confusion about Emgality (galcanezumab-gnlm) coverage runs deep among Michigan patients and even some healthcare providers. Part of the problem stems from the complexity of specialty drug approvals—Aetna (CVS Health) uses different criteria than other insurers, and requirements can change annually.

The bigger issue? Misinformation spreads faster than facts. Patients share outdated approval stories in online forums, while some providers make assumptions based on other CGRP inhibitors they've prescribed. Meanwhile, Aetna's actual policies are buried in lengthy PDF documents that few people read completely.

Counterforce Health helps patients, clinicians, and specialty pharmacies get prescription drugs approved by turning insurance denials into targeted, evidence-backed appeals. The platform ingests denial letters, plan policies, and clinical notes to identify the exact denial basis and draft point-by-point rebuttals aligned to the plan's own rules.

Let's separate myth from reality so you can navigate Aetna's requirements with confidence.

Common Myths vs. Facts

Myth 1: "If my doctor prescribes Emgality, Aetna has to cover it"

Fact: Prescription alone doesn't guarantee coverage. Aetna requires prior authorization with step therapy documentation—typically proof of failure or intolerance to at least two generic preventives like topiramate and propranolol, each tried for minimum 3 months at therapeutic doses.

Myth 2: "Once approved, I'm set for life"

Fact: Emgality approvals typically last 6-12 months and require renewal with updated clinical documentation. Aetna's renewal process demands proof of continued medical necessity and treatment response.

Myth 3: "Appeals rarely work—insurers always win"

Fact: Appeals succeed frequently when properly documented. Michigan patients have strong appeal rights through DIFS external review, with decisions binding on Aetna. The key is addressing the specific denial reasons with clinical evidence.

Myth 4: "I need 15+ migraine days per month for any CGRP drug"

Fact: While chronic migraine (≥15 headache days monthly) qualifies, Aetna also covers Emgality for high-frequency episodic migraine—typically 4-14 migraine days per month when preventives have failed. Documentation requirements include migraine diaries showing frequency and functional impact.

Myth 5: "Generic alternatives work just as well"

Fact: While Aetna requires trying generics first, clinical evidence supports CGRP inhibitors for patients who've failed conventional preventives. The FDA-approved indication specifically recognizes Emgality's unique mechanism for migraine prevention.

Myth 6: "All CGRP drugs have the same approval requirements"

Fact: Each CGRP inhibitor has distinct Aetna criteria. Emgality's subcutaneous injection requires different documentation than oral options like Qulipta (atogepant). Formulary placement and quantity limits vary by specific drug.

Myth 7: "I can't appeal if my doctor doesn't support it"

Fact: While physician support helps, patients can file appeals independently in Michigan. DIFS external review accepts patient-initiated requests with supporting medical records.

Myth 8: "Step therapy means I have to fail every possible generic first"

Fact: Aetna typically requires failure of two distinct classes—often an anticonvulsant (topiramate) and beta-blocker (propranolol). Contraindications or documented intolerance can override step therapy requirements with proper documentation.

What Actually Influences Approval

Understanding Aetna's real decision-making process helps you build a stronger case:

Clinical Documentation Quality

  • Detailed migraine history with ICD-10 codes (G43.x series)
  • Comprehensive prior treatment records with dates, doses, duration, and outcomes
  • Recent neurological evaluation ruling out secondary headache causes
  • Migraine diary showing frequency, severity, and functional impact

Step Therapy Compliance

  • Evidence of adequate trials (typically 3+ months each) of required preventives
  • Clear documentation of failure reasons: lack of efficacy, intolerance, or contraindications
  • Proper dosing attempts before declaring treatment failure

Submission Process

From our advocates: We've seen denials overturned simply by resubmitting with complete prior treatment documentation. One Michigan patient's appeal succeeded after adding pharmacy records showing actual fill dates and doses for previous preventives—details the initial PA lacked.

Avoid These Critical Mistakes

1. Incomplete Prior Treatment History Don't just list medication names. Include specific doses, duration of adequate trials, and documented reasons for discontinuation. Aetna's criteria require evidence of therapeutic failure, not just patient preference.

2. Missing Migraine Diary Documentation Submit at least 3 months of consistent headache tracking showing frequency, severity, and impact on daily activities. Generic statements about "frequent migraines" don't meet Aetna's evidence standards.

3. Wrong Submission Pathway Emgality requires specialty drug precertification through specific channels. Using standard PA forms or wrong portals causes automatic delays and potential denials.

4. Ignoring Renewal Deadlines Set calendar reminders for PA renewal 60-90 days before expiration. Gaps in coverage require starting the approval process from scratch.

5. Accepting Initial Denials Without Appeal Many first-level denials cite administrative issues rather than true medical necessity concerns. Counterforce Health's platform helps identify whether denials address actual clinical criteria or procedural gaps.

Your 3-Step Action Plan

Step 1: Document Your Case (This Week)

  • Request complete medical records from all providers who've treated your migraines
  • Start or update your migraine diary with frequency, severity (1-10), and functional impact
  • List all previous preventive medications with dates, doses, and outcomes

Step 2: Work With Your Provider (Next 2 Weeks)

  • Schedule appointment to review PA requirements and update clinical notes
  • Ensure your provider has access to Aetna's current criteria
  • Submit PA through proper channels with complete documentation

Step 3: Prepare for Potential Appeal (Ongoing)

  • Keep copies of all submissions and correspondence
  • Know your Michigan appeal rights and deadlines (180 days internal, 127 days external)
  • Consider professional appeal assistance if denied

Michigan-Specific Appeal Rights

Michigan offers robust protections for patients denied specialty drug coverage:

Internal Appeals with Aetna

  • Timeline: Up to 180 days from denial date
  • Process: Submit written appeal with additional clinical documentation
  • Expedited option: 72 hours for urgent medical needs

External Review Through DIFS

  • Timeline: 127 days after final internal denial
  • Process: File FIS 0018 form with supporting documents
  • Decision: Binding on Aetna within 60 days (72 hours for expedited)
  • Cost: Free to patients

Key Michigan Advantage Unlike some states, Michigan's external review decisions are binding. If DIFS rules in your favor, Aetna must provide coverage as directed.

FAQ: Real Questions, Real Answers

Q: How long does Aetna PA take in Michigan? A: Standard decisions within 30-45 days for pre-service requests. Expedited reviews within 24-72 hours when medically urgent.

Q: What if Emgality isn't on my formulary? A: Request formulary exception with medical necessity documentation. Non-formulary doesn't mean uncoverable—just requires additional justification.

Q: Can I request peer-to-peer review? A: Yes, your provider can request direct discussion with Aetna's medical director. This often resolves clinical disagreements faster than written appeals.

Q: Does step therapy apply if I failed preventives in another state? A: Yes, documented treatment failures from any location count toward step therapy requirements. Ensure records transfer completely.

Q: What counts as "adequate trial" for step therapy? A: Typically 3+ months at maximum tolerated therapeutic dose, unless stopped earlier due to intolerance or contraindications.

Q: Can I get emergency supplies while appealing? A: Aetna may provide 30-day emergency supplies during appeals, especially for continuing therapy or urgent medical needs.
