    • DDAVP trial results or contraindication notes
  2. Complete PA Form (Physician)
    • Use plan-specific hemophilia/VWD PA form
    • Include weight-based dosing calculations
    • Document clinical indication (acute bleed, surgery, prophylaxis)
  3. Submit Electronically (Clinic)
    • Via Premera provider portal or Regence online system
    • Include all supporting documentation
    • Request expedited review if urgent
  4. Track Status (Patient/Clinic)
    • Monitor through provider portal
    • Follow up within 48 hours if no acknowledgment
  5. Receive Decision (72 hours standard)
    • Approval: Coordinate with specialty pharmacy
    • Denial: Review reason and prepare appeal

Required Documentation Checklist

  • Confirmed VWD diagnosis with subtype
  • Laboratory results (VWF:RCo, VWF:Ag, FVIII)
  • Bleeding score assessment
  • DDAVP trial documentation or contraindication
  • Weight-based dosing calculations

Timing and Deadlines

Standard Prior Authorization Timeline

Process Step Timeframe Notes
PA Submission Same day Electronic submission preferred
Plan Review 72 hours Standard determination
Expedited Review 24 hours For urgent clinical situations
Appeal Filing 180 days After denial notification
Internal Appeal 30 days Plan review of denial
External Review 30 days IRO decision

When to Request Expedited Review

Request expedited processing when:

  • Active bleeding episode requiring immediate treatment
  • Pre-surgical prophylaxis with scheduled procedure
  • Delay would seriously jeopardize health
  • Emergency department or hospital admission pending
Tip: Document the urgent clinical situation clearly in your PA request to qualify for 24-hour expedited review.

Medical Necessity Criteria

Diagnosis Requirements

For Von Willebrand Disease:

  • Confirmed VWD Type 1, 2 (A, B, M, N), or 3
  • Laboratory documentation: VWF:RCo <50%, abnormal VWF:Ag/VWF:RCo ratio
  • Bleeding history consistent with VWD severity

For Hemophilia A:

  • Factor VIII deficiency with levels <40%
  • Documented bleeding episodes or surgical prophylaxis need

DDAVP Trial Documentation

Plans typically require evidence that desmopressin (DDAVP) is:

  • Contraindicated: cardiovascular disease, hyponatremia risk
  • Ineffective: inadequate VWF/FVIII response in trial
  • Inappropriate: VWD Type 2B or 3, severe bleeding

Dosing Requirements

Humate-P dosing must follow FDA-approved labeling:

  • VWD bleeding: 40-80 IU/kg VWF:RCo loading dose
  • Surgical prophylaxis: Individualized based on procedure risk
  • Maintenance: 40-60 IU/kg every 8-12 hours initially

Include vial optimization calculations to minimize wastage concerns.

Cost Considerations

Insurance Coverage Levels

Most Blue Cross plans cover Humate-P under the medical benefit rather than pharmacy benefit, meaning:

  • Subject to medical deductible
  • Coinsurance typically 10-30% after deductible
  • No retail pharmacy copay structure

Financial Assistance Options

  • CSL Behring Patient Assistance: Contact manufacturer for eligibility
  • Hemophilia Foundation Programs: Washington Chapter of National Hemophilia Foundation
  • Hospital Financial Aid: For infusion center administration
Note: Copay assistance programs may not apply to government insurance plans (Medicare, Medicaid).

Denials and Appeals

Common Denial Reasons & Solutions

Denial Reason How to Address Required Documentation
Missing VWD subtype Submit complete lab panel VWF multimer analysis, genetic testing
DDAVP not tried Document contraindication or trial Medical notes, lab results post-DDAVP
Excessive dosing Justify with clinical scenario Surgical risk, bleeding severity
Alternative available Show failure of other products Treatment history, adverse reactions

Appeals Process in Washington

Level 1: Internal Appeal

  • File within 180 days of denial
  • Submit additional clinical documentation
  • Request peer-to-peer review with plan medical director
  • Decision within 30 days

Level 2: External Review (IRO)

External Review Process

Washington's external review law (RCW 48.43.535) provides strong consumer protections:

  1. Eligibility: After final internal denial or plan deadline violations
  2. Timeline: 180 days to file from final denial
  3. Process: IRO reviews medical necessity independently
  4. Decision: Within 30 days (72 hours if expedited)
  5. Outcome: Binding on insurance plan if overturned

Specialty Pharmacy and Home Infusion

Network Requirements

Home Infusion vs. Clinic Administration

Home Infusion Covered When:

Troubleshooting Common Issues

PA Portal Problems

  • Portal down: Call plan's provider services line
  • Missing forms: Request current hemophilia PA form

  • Old records: Ensure labs are within 12 months
  • Missing signatures: Verify all forms are properly signed

Communication Breakdowns
