Medical Necessity Requirements

Aetna's Clinical Policy Bulletin 0864 defines Rylaze as medically necessary only when all of the following criteria are met:

Core Eligibility Criteria

1. Confirmed Diagnosis

  • Acute lymphoblastic leukemia (ALL) or lymphoblastic lymphoma (LBL)
  • Supported by pathology reports and appropriate ICD-10 codes
  • Common codes: C91.0x for ALL, C83.5 for LBL

2. Age Requirement

  • Patient must be ≥1 month old (per FDA labeling)

3. Documented Hypersensitivity

  • Previous exposure to E. coli-derived asparaginase (typically pegaspargase/Oncaspar)
  • Clinical documentation of hypersensitivity reaction including:
    • Type of reaction (anaphylaxis, urticaria, bronchospasm, etc.)
    • Severity and timing
    • Medical management required
    • Reason for discontinuation

4. Multi-Agent Chemotherapy

  • Rylaze must be used as part of a multi-agent chemotherapeutic regimen
  • Not approved as single-agent therapy
Note: Aetna considers all other indications experimental/investigational and not covered.

Step Therapy and Exceptions

Unlike many specialty drugs, Rylaze doesn't typically have formal step therapy requirements since it's specifically indicated for patients who've already failed E. coli asparaginase. However, Aetna will verify:

  • Prior E. coli asparaginase trial: Documentation that pegaspargase or another E. coli product was tried first
  • Failure reason: Clear evidence of hypersensitivity, not just treatment completion
  • Alternative considerations: Review of whether rechallenge with premedication was attempted (if clinically appropriate)

Medical Exception Pathway

If your clinical situation doesn't fit standard criteria, document:

  • Contraindications to E. coli products
  • Urgent need for asparaginase in treatment protocol
  • Risk-benefit analysis supporting Rylaze use

Site of Care and CVS Specialty Requirements

Aetna requires Rylaze to be:

  1. Dispensed through CVS Specialty Pharmacy exclusively
  2. Administered in qualified clinical settings (oncology office, hospital outpatient, or infusion center)
  3. Prescribed by or in consultation with an oncologist/hematologist

CVS Specialty Enrollment Process

Complete the CVS Specialty Oncology Injectable Enrollment Form with:

  • Prescribing oncologist information
  • Administration site details and shipping address
  • Patient diagnosis and insurance information
  • Planned dosing regimen
Tip: Coordinate delivery timing with your treatment schedule since Rylaze requires refrigerated storage.

Evidence to Support Medical Necessity

Clinical Guidelines Support

NCCN Guidelines recognize asparaginase as an essential component of ALL/LBL treatment protocols. When E. coli products cause hypersensitivity, Erwinia-derived asparaginase (Rylaze) is the recommended alternative.

FDA Labeling specifically indicates Rylaze for patients ≥1 month with ALL/LBL who have developed hypersensitivity to E. coli-derived asparaginase.

Key Documentation Elements

Include in your medical necessity letter:

  • Treatment protocol: Specific regimen (e.g., pediatric-inspired, Hyper-CVAD)
  • Asparaginase role: Why asparaginase is critical for this patient's cure potential
  • E. coli failure: Detailed hypersensitivity history with dates and severity
  • No alternatives: Why other asparaginase products aren't suitable
  • Monitoring plan: How you'll track efficacy and safety

From our advocates: We've seen cases where patients initially denied Rylaze for "insufficient hypersensitivity documentation" successfully overturned their denials by submitting emergency department records from their E. coli asparaginase reactions, even when the original reaction occurred at a different hospital. The key was obtaining complete records that showed the severity and medical management required.

Diagnosis not supported Provide pathology reports, staging documents, ICD-10 codes 1-2 days
Not part of multi-agent regimen Submit complete treatment protocol showing concurrent agents Same day
Site of care restrictions Clarify administration setting, provide facility credentials 2-3 days
Experimental/investigational Reference FDA approval, NCCN guidelines, Aetna's own policy 1-2 days

FAQ

How long does Aetna CVS Health prior authorization take in Pennsylvania? Standard PA decisions are made within 15 business days; urgent requests within 72 hours. Pennsylvania law requires faster decisions for urgent medical needs.

What if Rylaze is non-formulary on my plan? All Aetna plans require PA for Rylaze regardless of formulary status. Non-formulary drugs may have higher copays but can still be covered when medically necessary.

Can I request an expedited appeal? Yes, if delays would seriously jeopardize your health. Mark both PA requests and appeals as "urgent" and include physician certification of medical urgency.

Does step therapy apply if I failed E. coli asparaginase outside Pennsylvania? No, documented hypersensitivity from any location counts toward Rylaze medical necessity. Provide all available records regardless of where treatment occurred.

What happens if CVS Specialty can't deliver to my clinic? Contact CVS Specialty to arrange alternative delivery or storage solutions. Some plans allow temporary exceptions for delivery logistics.

How do I know if my Aetna plan is eligible for Pennsylvania external review? Commercial plans regulated by Pennsylvania qualify. Self-funded employer plans typically use federal external review. Check with your HR department or the Pennsylvania Insurance Department.

Can I appeal while continuing treatment? Yes, file appeals immediately while working with your oncologist on alternative coverage or payment arrangements. Don't delay treatment for coverage decisions.

What if I need Rylaze for an off-label indication? Aetna considers off-label uses experimental/investigational. You'll need extensive clinical evidence and may need to pursue external review or coverage through clinical trials.
