Policy Overview
UnitedHealthcare covers Elzonris (tagraxofusp-erzs) across HMO, PPO, and Medicare Advantage plans, but all require prior authorization through OptumRx. The drug carries a list price of approximately $38,579 per 1,000 mcg vial, making it one of the most expensive specialty oncology treatments.
Plan Types and Coverage:
- Commercial HMO/PPO: Standard prior authorization required
 - Medicare Advantage: Enhanced documentation requirements
 - Medicaid (Medi-Cal): Covered through California's managed care plans
 
Note: UnitedHealthcare's 2025 policy updates eliminated prior authorization for some chronic medications, but Elzonris remains subject to full PA requirements due to its specialized indication and safety profile.

Indication Requirements
FDA-Approved Indication: Elzonris is approved for blastic plasmacytoid dendritic cell neoplasm (BPDCN) in adults and pediatric patients ≥2 years old.
UnitedHealthcare's Medical Necessity Criteria:
- Confirmed BPDCN diagnosis with pathology report
 - CD123-positive disease documented by immunohistochemistry
 - Patient age ≥2 years
 - Adequate organ function for safe administration
 
Off-Label Use: UnitedHealthcare typically does not cover off-label use of Elzonris. Any non-FDA approved indication requires extensive documentation and often faces denial, requiring appeals with compelling clinical evidence.
Step Therapy & Exceptions
Step Therapy Requirements: UnitedHealthcare may require documentation of prior therapy attempts, though options for BPDCN are extremely limited.
Medical Exception Pathways:
- First-line therapy: Often approved if BPDCN diagnosis is confirmed
 - Contraindications: Document why other treatments aren't suitable
 - Prior failures: Include records from previous insurers if applicable
 
Required Documentation for Exceptions:
- Clinical notes detailing treatment history
 - Pathology reports confirming diagnosis
 - Physician attestation of medical necessity
 
Quantity & Frequency Limits
Dosing Parameters UnitedHealthcare Monitors:
- Weight-based dosing: 12 mcg/kg/day for Days 1-5 of each 21-day cycle
 - Maximum cycles: Typically 2-3 cycles for initial authorization
 - Reauthorization required for additional cycles
 
Renewal Requirements:
- Response assessment after 2 cycles
 - Toxicity evaluation and CLS monitoring documentation
 - Continued medical necessity justification
 
Required Diagnostics
Pre-Treatment Requirements:
| Test | Requirement | Documentation Needed | 
|---|---|---|
| Pathology | CD123-positive BPDCN | CLIA-certified lab report | 
| Albumin | ≥3.2 g/dL | Within 7 days of treatment | 
| Creatinine | ≤1.8 mg/dL | Within 7 days of treatment | 
| Cardiac function | Normal EF | ECHO or MUGA within 30 days | 
| Weight | Baseline established | Daily monitoring plan | 
Ongoing Monitoring Documentation:
- Pre-dose albumin and weight checks
 - Daily weight monitoring during treatment
 - CLS symptom assessment protocols
 
Site of Care Requirements
UnitedHealthcare's Site of Care Policy for Elzonris:
Initial Cycles (1-2):
- Required: Inpatient administration only
 - Monitoring: Minimum 24 hours post-infusion observation
 - Rationale: CLS risk mitigation
 
Subsequent Cycles:
- Preferred: Inpatient or hospital outpatient with 4-hour observation
 - Alternative sites: Only with documented tolerance of prior cycles
 - Documentation: CLS monitoring plan and emergency protocols
 
UnitedHealthcare generally prefers lower-cost settings but recognizes Elzonris requires enhanced monitoring per FDA labeling. See their Provider-Administered Drugs Site of Care policy.
Evidence to Support Medical Necessity
Primary Evidence Sources:
- FDA Prescribing Information: Include relevant sections on indication and dosing
 - NCCN Guidelines: Reference BPDCN treatment recommendations
 - Peer-reviewed literature: Key studies supporting efficacy
 - Pathology reports: CD123 immunohistochemistry results
 
How to Structure Clinical Evidence:
- Lead with FDA approval status
 - Cite specific NCCN guideline sections
 - Include patient-specific factors supporting use
 - Document absence of suitable alternatives
 
Tip: UnitedHealthcare's medical directors respond well to evidence that directly addresses their coverage criteria. Focus on medical necessity rather than general drug efficacy.
Sample Medical Necessity Statement
Template Structure:
"[Patient] is a [age]-year-old with biopsy-confirmed blastic plasmacytoid dendritic cell neoplasm (BPDCN), CD123-positive by immunohistochemistry performed at [CLIA lab]. BPDCN is a rare, aggressive hematologic malignancy with poor prognosis without treatment. Elzonris (tagraxofusp-erzs) is FDA-approved specifically for this indication and represents the only targeted therapy available.
Pre-treatment evaluation shows adequate organ function with albumin [value] g/dL, creatinine [value] mg/dL, and normal cardiac function. The patient will receive treatment in an inpatient setting with comprehensive CLS monitoring including daily weights, albumin levels, and clinical assessment per FDA-mandated safety protocols.
Given the rarity of BPDCN and lack of alternative targeted therapies, Elzonris is medically necessary and appropriate for this patient's condition."

Common Denial Reasons & Solutions
| Denial Reason | Solution Strategy | Required Documentation | 
|---|---|---|
| "Experimental/investigational" | Cite FDA approval for BPDCN | FDA label, approval letter | 
| "Not medically necessary" | Emphasize BPDCN rarity, poor prognosis | Pathology report, prognosis literature | 
| "Missing CD123 documentation" | Submit immunohistochemistry results | CLIA-certified lab pathology report | 
| "Inadequate CLS monitoring plan" | Detail safety protocols | Monitoring checklist, albumin schedule | 
| "Site of care inappropriate" | Justify inpatient requirement | CLS risk documentation, FDA warnings | 
| "Quantity exceeds limits" | Provide weight-based calculations | Dosing worksheet, patient weight | 
From our advocates: "We've seen UnitedHealthcare initially deny Elzonris based on 'experimental' status, even though it's FDA-approved. The key is immediately responding with the FDA approval letter and emphasizing that BPDCN has no other targeted therapies. This combination often reverses denials at the first internal appeal level."
Quick Scripts for Common Situations:
Peer-to-Peer Request Script: "I'm calling to request a peer-to-peer review for [patient name], member ID [number]. We received a denial for Elzonris for confirmed BPDCN. This is an FDA-approved indication with no alternative targeted therapies available. Can we schedule a clinical discussion with your medical director?"
Patient Advocacy Script: "I'm calling about my prior authorization denial for Elzonris. My diagnosis is BPDCN, which is specifically listed in the FDA approval. I'd like to understand what additional documentation is needed to demonstrate medical necessity."
