When Formulary Alternatives Make Sense

Before pursuing Filsuvez, Aetna CVS Health typically requires documented trials of formulary alternatives. This isn't just bureaucratic red tape—for some patients with mild-to-moderate epidermolysis bullosa (EB), standard wound care approaches can be effective and are immediately accessible.

Formulary alternatives make sense when:

  • Your EB wounds are localized and not severely infected
  • You haven't tried standard topical antimicrobials with appropriate dressings
  • Cost is a significant concern while building your insurance case
  • You're waiting for specialty dermatology consultation

Alternatives may not be appropriate if:

  • You have extensive, non-healing wounds despite standard care
  • Previous topical treatments caused skin stripping or worsening
  • Your EB subtype (junctional or dystrophic) requires specialized therapy
  • Standard dressings consistently cause trauma during changes
Note: Aetna CVS Health's formulary exception process requires demonstrating that alternatives are "ineffective, contraindicated, not tolerated, or likely to cause adverse effects" before approving non-formulary treatments.

Typical Alternatives for EB Wound Care

First-Line Topical Antimicrobials (Usually Covered)

Mupirocin (Bactroban)

  • Coverage: Typically preferred tier with minimal restrictions
  • Use: Infected EB wounds, applied 2-3 times daily
  • Pros: Effective against staph and strep; well-tolerated
  • Cons: May cause contact dermatitis; resistance can develop

Bacitracin

  • Coverage: Often tier 1 (lowest copay)
  • Use: Minor wound prevention; over-the-counter available
  • Pros: Inexpensive, widely available
  • Cons: High allergy rates; limited spectrum

Silver Sulfadiazine (Silvadene)

  • Coverage: Usually covered with prior authorization
  • Use: Burn-like wounds, broad antimicrobial
  • Pros: Broad spectrum activity
  • Cons: Can delay healing; not recommended for EB due to adherence issues

Specialized Dressing Coverage

Silicone-Based Dressings

  • Coverage: Often covered under durable medical equipment (DME)
  • Examples: Adaptic, Mepitel, silicone foam dressings
  • Pros: Atraumatic removal, reduces pain during dressing changes
  • Cons: May require DME prior authorization; quantity limits common
Important: Traditional petroleum-based ointments and adhesive dressings are contraindicated in EB care as they cause skin stripping and trauma during removal.

Coverage Comparison: Alternatives vs. Filsuvez

Treatment Aetna Coverage Typical Copay PA Required Documentation Needed
Mupirocin Preferred formulary $10-30 Usually no Basic prescription
Bacitracin Tier 1 $5-15 No None
Silver sulfadiazine Non-preferred $20-50 Often yes Wound photos, notes
Silicone dressings DME coverage 20% coinsurance Sometimes Prescription, diagnosis
Filsuvez Non-formulary $500+ or denied Always Extensive documentation

Source: Based on Aetna formulary documentation and typical specialty drug coverage patterns.

Exception Strategy: When to Request Filsuvez

Timing Your Request

Request Filsuvez when you can document:

  1. Confirmed EB diagnosis with genetic testing results
  2. Failed trials of at least 2-3 formulary alternatives over 3-6 months
  3. Photographic evidence of wound progression despite standard care
  4. Specialist consultation from dermatology or EB center

Required Documentation Checklist

Medical Records Must Include:

  • Confirmed junctional or dystrophic EB diagnosis (≥6 months old per FDA indication)
  • Detailed wound assessment photos with measurements
  • Documentation of formulary alternatives tried, duration, and outcomes
  • Specialist notes supporting medical necessity
  • Pain assessments and quality-of-life impacts
  • ICD-10 codes for specific EB subtype

Submit Prior Authorization to:

  • Phone: 1-866-814-5506 (Aetna Specialty Precertification)
  • Fax: 1-866-249-6155 (Specialty PA requests)
  • Portal: Availity (for providers)
Tip: Request expedited review (24-hour decision) if wounds are infected or rapidly worsening. Standard reviews take up to 72 hours after complete documentation is received.

Switching Logistics and Provider Coordination

Working with Your Healthcare Team

Dermatology Coordination: Your dermatologist or EB specialist should lead the prior authorization process, as they can provide the most compelling medical necessity documentation. If you don't have a specialist, ask for a referral—Aetna typically covers consultations for rare diseases like EB.

Pharmacy Coordination: Filsuvez will likely be dispensed through CVS Specialty Pharmacy if approved. They can help coordinate:

  • Prior authorization status updates
  • Patient assistance program enrollment
  • Delivery scheduling and storage requirements

Documentation During Alternative Trials

Keep detailed records of:

  • Exact products used and duration of each trial
  • Wound measurements and photos (with dates)
  • Pain levels and functional impacts
  • Any adverse reactions or skin damage from dressing changes
  • Healthcare provider observations and recommendations

This documentation becomes crucial evidence for your Filsuvez exception request.

Building Your Case for Future Filsuvez Approval

Strengthening Your Medical Necessity Argument

Clinical Evidence to Gather:

  • FDA approval documentation for Filsuvez in junctional/dystrophic EB
  • Published guidelines from DEBRA International or dermatology societies
  • Peer-reviewed studies showing birch triterpenes efficacy in EB
  • Expert opinion letters from EB specialists

Document Treatment Failures Systematically:

  1. Specific outcomes: "Mupirocin trial for 8 weeks showed no wound size reduction"
  2. Functional impacts: "Unable to change dressings without significant pain/bleeding"
  3. Quality of life: "Missed 15 school/work days due to wound complications"
  4. Safety concerns: "Standard adhesive dressings caused additional skin breakdown"

Contact Washington Insurance Commissioner:

From our advocates: "We've seen several successful IRO appeals for rare disease medications when patients submitted comprehensive wound photography, detailed treatment timelines, and strong specialist letters. The key was showing that formulary alternatives weren't just ineffective—they were potentially harmful due to the patient's specific EB subtype."

FAQ: Common Questions

How long does Aetna CVS Health prior authorization take in Washington? Standard PA decisions take up to 72 hours after complete documentation is received. Expedited reviews (for urgent medical need) are decided within 24 hours.

What if Filsuvez is completely non-formulary? Non-formulary drugs can still be covered through formulary exceptions when medical necessity is demonstrated and alternatives have failed or are contraindicated.

Can I request an expedited appeal for EB wounds? Yes, if wounds are infected, rapidly worsening, or causing significant functional impairment, you can request expedited internal appeals and IRO reviews with faster decision timelines.

Does step therapy apply if I tried alternatives outside Washington? Medical records from other states are generally accepted, but ensure your current Washington provider documents and confirms the treatment failures in their notes.

What happens if the IRO denies my appeal? IRO decisions are binding on insurance companies but final for coverage disputes. You may still contact the Washington Insurance Commissioner for guidance on other options or file complaints about the process.

How do I coordinate between CVS Specialty Pharmacy and my local pharmacy? If approved, Filsuvez will typically be dispensed through CVS Specialty. They'll coordinate with your prescriber directly, but keep your local pharmacy informed for other EB-related supplies and medications.

Can my family member help with the appeals process? Yes, but you'll need to complete authorization forms allowing them to speak with Aetna on your behalf. These forms are available through member services.

What if my employer plan has different rules? Self-funded employer plans may have different appeal processes. Check if your plan follows Washington state rules or federal ERISA guidelines, which have different timelines and external review options.
