How to Get Revcovi (elapegademase) Approved by Aetna CVS Health in California: Complete Prior Authorization Guide

Answer Box: Quick Path to Approval

Revcovi (elapegademase) requires prior authorization from Aetna CVS Health in California. Most approvals succeed when you submit: (1) confirmed ADA-SCID diagnosis with enzyme testing or genetic results, (2) specialist consultation notes, and (3) documentation that bone marrow transplant failed or isn't possible. First step today: Have your immunologist gather diagnostic labs and complete the California-specific Aetna prior authorization form. Standard decisions take 24-48 hours; if denied, California's Independent Medical Review (IMR) has strong overturn rates for specialty drugs.

What This Guide Covers

This guide helps patients with adenosine deaminase severe combined immunodeficiency (ADA-SCID) and their clinicians navigate Aetna CVS Health's prior authorization process for Revcovi (elapegademase) in California. We'll walk through the exact forms, documentation requirements, timelines, and appeal options specific to California residents.

Revcovi is an enzyme replacement therapy that costs approximately $11,851 per 1.5 mL vial and requires specialist oversight. Most denials occur due to incomplete diagnostic documentation or missing evidence that definitive therapies (bone marrow transplant or gene therapy) have failed or aren't possible.

Before You Start: Verify Your Coverage

Check Your Plan Type

Aetna CVS Health plans in California fall under two regulatory bodies:

  • DMHC-regulated plans (most HMOs and managed care): Stronger appeal rights through Independent Medical Review
  • CDI-regulated plans (some PPOs): Similar but separate external review process

Call the member services number on your insurance card to confirm which regulator oversees your plan—this affects your appeal rights later.

Medical vs. Pharmacy Benefit

Revcovi is typically covered under your medical benefit, not pharmacy benefit, because it requires clinical administration. The medication is dispensed through CVS Specialty pharmacy, not retail CVS locations, due to cold storage requirements.

Formulary Status

Revcovi appears on Aetna's specialty drug tier for 2025, requiring prior authorization but not excluded from coverage. Your out-of-pocket costs will depend on your specific plan's specialty tier copay or coinsurance structure.

Gather Required Documentation

Essential Diagnostic Evidence

ADA-SCID Confirmation (choose one):

  • ADA enzyme activity test showing <1% of normal levels in blood or dried blood spot
  • Genetic testing confirming pathogenic bi-allelic ADA gene mutations
  • ICD-10 code: D81.3 (Adenosine deaminase deficiency)

Specialist Documentation

Required from your immunologist, geneticist, or metabolic specialist:

  • Current consultation notes (within 30 days)
  • Treatment plan with specific dosing (typically 0.2-0.4 mg/kg weekly, intramuscular)
  • Medical necessity letter explaining why Revcovi is appropriate
  • Documentation of specialist credentials

Laboratory Results

Current labs (within 30 days):

  • Complete blood count with differential
  • Platelet count (must be ≥50,000/μL)
  • Current weight for dosing calculations
  • If available: erythrocyte dATP levels, plasma ADA activity

Prior Therapy Documentation

Evidence that definitive treatments have failed or aren't possible:

  • Bone marrow transplant consultation notes showing ineligibility or failure
  • Gene therapy program evaluation (if applicable)
  • Documentation that patient is awaiting definitive therapy and needs bridge treatment
Tip: Most denials occur because payers require proof that curative therapies (transplant or gene therapy) were considered first. Have your specialist explicitly document why these aren't currently feasible.

If Your Request Is Denied

Common Denial Reasons and Solutions

Denial Reason Solution
"Diagnosis not confirmed" Submit enzyme activity test or genetic results with ICD-10 code D81.3
"Step therapy not completed" Document why bone marrow transplant/gene therapy failed or isn't possible
"Not medically necessary" Strengthen medical necessity letter with specialist rationale
"Experimental/investigational" Cite FDA approval and established clinical use

First-Level Internal Appeal

Timeline: File within 60 days of denial notice Process: Submit additional documentation addressing specific denial reasons Decision timeframe: 30 days for standard appeals, 72 hours for urgent cases

Peer-to-Peer Review

Request a peer-to-peer review where your specialist discusses the case directly with Aetna's medical director. This often resolves complex cases more efficiently than written appeals.

California's Independent Medical Review Process

When IMR Applies

After exhausting Aetna's internal appeals, California residents can request an Independent Medical Review through the Department of Managed Health Care (DMHC) if the denial involves:

  • Medical necessity determinations
  • Experimental/investigational designations
  • Emergency or urgent care disputes

IMR Success Rates

California IMR data shows 68% of requests result in patients receiving the requested service. For specialty drugs specifically, overturn rates vary but tend to be favorable when proper documentation supports medical necessity.

IMR Timeline and Process

Standard IMR: Decision within 45 days Expedited IMR: Decision within 7 days (often 72 hours for urgent cases) Cost: Free to patients Decision: Binding on Aetna

To file an IMR:

  1. Complete internal appeals with Aetna first (unless urgent)
  2. Apply online at DMHC website or call 888-466-2219
  3. Submit all relevant medical records and documentation
  4. Independent physician specialists review your case
From our advocates: "We've seen several ADA-SCID cases where initial denials were overturned at IMR when families submitted comprehensive diagnostic workups and clear documentation that transplant wasn't immediately feasible. The key is having your specialist explicitly explain why enzyme replacement therapy is the appropriate bridge treatment while awaiting definitive options."

Renewal and Re-Authorization

When to Reapply

Most Aetna approvals for Revcovi require annual renewal. Set calendar reminders 60 days before your authorization expires to allow processing time.

Required Evidence for Renewal

Document treatment response:

  • Trough plasma ADA activity ≥30 mmol/hr/L
  • Erythrocyte dAXP levels <0.02 mmol/L
  • Improved lymphocyte counts
  • Reduced infection frequency or severity
  • Absence of serious adverse reactions

Updated treatment plan:

  • Current weight and dose adjustments
  • Continued specialist oversight
  • Ongoing monitoring schedule
  • Status of definitive therapy options (transplant/gene therapy)

FAQ

How long does Aetna CVS Health prior authorization take in California? Most decisions are made within 24-48 hours for complete submissions. Complex cases may take up to 15 business days.

What if Revcovi isn't on my formulary? Request a formulary exception with your prior authorization. Include medical necessity documentation and evidence that formulary alternatives aren't appropriate for ADA-SCID.

Can I request an expedited review? Yes, if delays would seriously jeopardize your health. Your doctor must document the urgent nature of the request.

Does step therapy apply if I've tried treatments outside California? Previous treatment failures from other states should be documented and submitted. Aetna typically accepts this evidence regardless of where treatment occurred.

What happens if I miss an appeal deadline? Contact DMHC immediately at 888-466-2219. They may accept late appeals in certain circumstances, especially if the delay wasn't your fault.

How much will Revcovi cost with Aetna coverage? Your out-of-pocket cost depends on your plan's specialty tier structure. Contact member services for specific copay or coinsurance amounts.
