Why Virginia's Rules Matter for Aetna CVS Health Coverage

Virginia's insurance regulations provide important protections that directly impact how Aetna CVS Health handles Amondys 45 (casimersen) coverage decisions. Understanding these state-specific rights can make the difference between a denial and approval.

Virginia's Key Protections:

  • Step therapy exceptions: Virginia Code § 38.2-3407.9:05 requires insurers to grant exceptions when preferred drugs are contraindicated, ineffective, or previously failed
  • External review rights: The Virginia State Corporation Commission provides binding independent review of medical necessity denials
  • Rare disease advocacy: Virginia's Rare Disease Council (established 2021) recognizes special coverage needs for rare conditions like DMD
Note: These protections apply to Virginia-regulated commercial plans. Self-funded employer plans may opt into Virginia's process but aren't automatically covered.

Line-of-Business Differences:

  • Commercial Aetna: Full Virginia protections apply, 180-day appeal deadline
  • Aetna Better Health (Medicaid): 60-day appeal deadline, expedited review in 48-72 hours
  • Medicare Advantage: Federal CMS timelines override state rules

Prior Authorization Requirements and Timelines

Aetna CVS Health requires prior authorization for all Amondys 45 prescriptions. The 2025 Participating Provider Precertification List explicitly includes casimersen as requiring precertification.

Standard Review Timeline

  • Initial decision: 30-45 days for commercial plans
  • Expedited review: 72 hours with physician certification of urgency
  • Medicaid (Cardinal Care/FAMIS): 72 hours expedited, 48 hours for FAMIS urgent cases

Required Documentation

1. Genetic Testing Proof

  • Laboratory report showing DMD gene mutation amenable to exon 45 skipping
  • Must include specific mutation (e.g., "deletion of exons 44-45")
  • CLIA-accredited lab required

2. Functional Assessment

  • 6-minute walk test showing ≥300 meters independent ambulation
  • Test must be within 6 months of request
  • Performed by qualified healthcare provider

3. Age Documentation

  • Birth certificate or equivalent
  • Treatment must begin before 14th birthday
  • Timeline documentation showing planned start date

4. Specialist Care

  • Prescription from neurologist or neuromuscular specialist
  • Documentation of DMD management experience
  • Ongoing monitoring plan for kidney function

Virginia's Step Therapy Protections

Virginia's step therapy law provides strong protections for patients requiring specialty medications like Amondys 45. Under Virginia Code § 38.2-3407.9:05, insurers must grant exceptions when:

Automatic Exception Criteria:

  1. Required step drug is contraindicated
  2. Step drug would be ineffective based on patient characteristics
  3. Patient previously tried and failed step therapy drug
  4. Patient is stable on current non-preferred therapy

Timeline Requirements:

  • Standard requests: 72-hour response required
  • Urgent situations: 24-hour response for life/health risks
  • Appeals allowed through existing plan procedures
Virginia Advantage: NORD grades Virginia's step therapy protections with an "A" overall, recognizing strong exceptions processes and clinical standards.

Using Step Therapy Protections for Amondys 45

Since Amondys 45 targets a specific genetic mutation, other exon-skipping drugs (targeting different exons) are not therapeutically equivalent. In your exception request, emphasize:

  • Genotype-specific indication: Only exon 45-skipping agents work for your mutation
  • No therapeutic alternatives: Other DMD treatments don't provide exon 45 skipping
  • Clinical guidelines: FDA approval based on mutation-specific efficacy

Appeals Process: Internal and External Review

Internal Appeals with Aetna CVS Health

Filing Deadlines:

  • Commercial plans: 180 days from denial notice
  • Medicaid plans: 60 days from denial notice
  • Medicare Advantage: Follow CMS timelines

Expedited Appeal Process:

  1. Check "expedited" on appeal form
  2. Include physician statement documenting urgency
  3. Explain how delay could harm health or function
  4. Aetna responds within 72 hours (commercial) or 48-72 hours (Medicaid)

Virginia External Review Process

After exhausting Aetna's internal appeals, Virginia residents can request binding external review through the State Corporation Commission.

Eligibility Requirements:

  • Final denial based on medical necessity or experimental/investigational status
  • Request filed within 120 days of final internal denial
  • Applies to Virginia-regulated plans (not all self-funded employer plans)

How to File:

  1. Complete Form 216-A (External Review Request)
  2. Include final Aetna denial letter and supporting medical records
  3. Submit to: State Corporation Commission, Bureau of Insurance – External Review
  4. Contact: [email protected] or 1-877-310-6560

Timeline:

  • Standard review: 45 days for decision
  • Expedited review: 72 hours with physician certification
Key Advantage: External review decisions are binding on Aetna but not on you – if you lose, you can still pursue other options.

Common Denial Reasons and Solutions

"Genetic Testing Insufficient"

Solution: Submit complete lab report with specific language stating "mutation amenable to exon 45 skipping." Avoid relying on problem list diagnoses alone.

"Age Criterion Not Met"

Solution: Provide birth certificate and signed physician note confirming treatment initiation before 14th birthday. If already older, appeal will require strong medical necessity argument.

"Functional Requirements Not Documented"

Solution: Obtain current 6-minute walk test showing ≥300 meters independent ambulation. Include specialist interpretation of results.

"Non-Specialist Prescriber"

Solution: Have neuromuscular specialist assume prescribing or provide co-signature with documentation of DMD experience.

"Experimental/Investigational"

Solution: Cite FDA approval for exon 45-amenable DMD and include peer-reviewed literature supporting use. Request external review if denied.

Can you transfer me to someone who handles specialty drug appeals?"

Medical Necessity Letter Key Points

Your specialist should include:

  3. Functional status: Current ambulatory ability and 6MWT results
  4. Treatment urgency: Risk of irreversible muscle loss without treatment

Does Virginia's step therapy protection apply to out-of-state prior treatments? Yes, Virginia law recognizes previous trials under current or prior plans. Document any failed therapies with dates, doses, and outcomes.
