Understanding Aetna's Rylaze Coverage Criteria

Aetna considers Rylaze (asparaginase erwinia chrysanthemi [recombinant]-rywn) medically necessary under specific conditions outlined in their Clinical Policy Bulletin #0864:

Coverage Requirements at a Glance

Requirement What It Means Documentation Needed
Diagnosis ALL (ICD-10: C91.0) or LBL (C83.5); patient ≥1 month old Pathology reports, oncology notes
Prior Hypersensitivity Documented reaction to E. coli asparaginase (pegaspargase, Elspar) ER records, hospital notes, reaction details with dates
Treatment Context Part of multi-agent chemotherapy regimen Protocol documentation, NCCN guidelines reference
Dosing 25 mg/m² IM every 48 hours or M/W/F schedule Medical necessity letter with BSA calculations

Key Point: Aetna covers Rylaze only when patients have documented hypersensitivity to E. coli-derived asparaginase products. Vague "allergic reaction" notes won't suffice—you need specific dates, symptoms (anaphylaxis, pancreatitis, thrombosis), and treatment details.

From Our Advocates: We've seen denials overturned when families provided ER discharge summaries showing "anaphylaxis to pegaspargase requiring epinephrine" with exact dates and lab values. The more specific your hypersensitivity documentation, the stronger your case becomes.

Prior Authorization: Step-by-Step Process

Step 1: Gather Required Documentation (1-2 days)

  • Insurance card and member ID
  • Complete medical records showing hypersensitivity to prior asparaginase
  • Current treatment protocol and dosing plan
  • Oncologist's medical necessity letter

Step 2: Submit PA Request (Same day)

Use Aetna's official Rylaze precertification form. Submit via:

  • Fax: 1-888-267-3277
  • Provider portal: Aetna's online system
  • Standard processing: 3-5 business days
  • Urgent requests: 72 hours (requires physician certification of medical urgency)

Step 3: Track Your Request

  • Log into Aetna provider portal for status updates
  • Call provider services if no response within expected timeframe
  • Document all interactions with reference numbers

Counterforce Health helps patients and clinicians navigate complex prior authorization requirements like these by analyzing denial patterns and crafting targeted, evidence-backed appeals. Our platform identifies exactly what documentation payers need and formats it according to their specific requirements. Learn more about our services.

Common Denial Reasons and How to Fix Them

Denial Reason How to Overturn Required Documentation
"No documented hypersensitivity" Submit detailed reaction records ER notes, discharge summaries, lab values showing pancreatitis/allergic response
"Not medically necessary" Provide treatment protocol and guidelines NCCN ALL/LBL guidelines, oncologist letter explaining asparaginase role
"Experimental/investigational" Reference FDA approval and Aetna policy FDA label, Aetna CPB #0864 showing covered indications
"Incorrect dosing regimen" Clarify protocol-specific requirements Treatment plan showing 25 mg/m² q48h or M/W/F schedule
