Work With Your Doctor to Get Defitelio (Defibrotide) Approved by Aetna (CVS Health) in California: Complete Guide With Forms and Appeals

Answer Box: Getting Defitelio (Defibrotide) Approved by Aetna (CVS Health) in California

Defitelio (defibrotide) requires prior authorization from Aetna (CVS Health) for severe hepatic veno-occlusive disease (VOD/SOS) with organ dysfunction post-stem cell transplant. The fastest path to approval: (1) Have your transplant team submit the PA through Aetna's provider portal with complete VOD/SOS documentation, (2) Request expedited review due to life-threatening urgency, and (3) Enroll in Jazz Pharmaceuticals' support program for appeals assistance. California patients have strong appeal rights through DMHC Independent Medical Review if denied.

Set Your Goal: Understanding Approval Requirements

Your partnership with your transplant team centers on one critical objective: demonstrating that Defitelio meets Aetna (CVS Health)'s medical necessity criteria for severe hepatic VOD/SOS following hematopoietic stem cell transplantation (HSCT).

Coverage at a Glance

Requirement What It Means Where to Find It Timeline
Prior Authorization PA required before dispensing Aetna Precertification Lists Submit 2+ weeks before need
FDA Indication Match Severe VOD/SOS with renal or pulmonary dysfunction FDA Label Must document in records
Post-HSCT Timing VOD/SOS occurring after stem cell transplant Medical records Establish clear timeline
Organ Dysfunction Renal (creatinine doubling) or pulmonary involvement Lab results, imaging Current documentation needed

Key insight: Aetna (CVS Health) follows FDA labeling closely for Defitelio, but denials often occur due to incomplete documentation of organ dysfunction or unclear post-HSCT timing rather than coverage exclusions.

Tip: Request expedited review immediately when submitting your PA. Defitelio is used for life-threatening conditions where delays can worsen outcomes.

Visit Preparation: Gathering Your Medical History

Before meeting with your transplant team, compile a comprehensive timeline that demonstrates medical necessity and urgency.

  • Standard review exceeding 30 days without decision
  • Denial without clear medical reasoning

Professional Escalation Steps

  1. Transplant Coordinator: First contact for status updates
  2. Medical Director Review: Request if initial denial seems inappropriate
  3. State Regulator: California DMHC for process violations
  4. External Review: Independent Medical Review for medical necessity disputes

California Appeal Rights and External Review

California provides robust appeal protections through the Department of Managed Health Care (DMHC) for most health plans.

Internal Appeal Process

Timeline and Requirements:

  • File within 180 days of denial notice
  • Include all supporting documentation
  • Request expedited review for urgent medical needs
  • Expect decision within 30-45 days (72 hours for expedited)

Independent Medical Review (IMR)

If Aetna (CVS Health) upholds the denial, California patients can request binding external review through DMHC.

IMR Success Rates: Based on 2023 DMHC data, patients achieved favorable outcomes in approximately 55% of medical necessity appeals, with even higher success rates for specialty medications when proper documentation supports medical necessity.

IMR Process:

  1. File IMR application at healthhelp.ca.gov within 6 months of final denial
  2. DMHC assigns independent physician reviewers
  3. Standard IMR decision within 45 days; expedited within 7 days
  4. Decision is binding on Aetna (CVS Health)

No Cost to Patients: California law prohibits fees for IMR requests, and insurers bear the cost of independent review.
