Visit Preparation: What to Document

Work with your transplant team to create a comprehensive timeline of your condition. This documentation forms the foundation of your coverage request.

Symptom Timeline

  • Date of HSCT procedure and conditioning regimen used
  • Day of VOD/SOS symptom onset (typically within 30 days post-transplant)
  • Progression of symptoms: weight gain, abdominal pain, hepatomegaly
  • Development of organ dysfunction

Treatments Tried and Failed

  • Supportive care measures: diuretics, fluid restriction
  • Response to interventions or lack thereof
  • Progression despite standard management

Functional Impact Documentation

  • Daily weight measurements showing fluid retention
  • Pain scores and impact on quality of life
  • Inability to participate in normal activities
  • Impact on transplant recovery goals
Tip: Keep a daily symptom diary with weights, pain levels, and functional capacity. This creates powerful evidence of disease progression and treatment urgency.

Building Your Evidence Kit

Laboratory Evidence

Compile serial lab results showing:

  • Liver function tests: Rising bilirubin (target ≥2 mg/dL), AST/ALT elevation
  • Renal function: Creatinine doubling from baseline, BUN elevation
  • Coagulation studies: Platelet count, PT/INR trends
  • Fluid status: Weight gain >5% from baseline

Imaging Studies

Essential imaging includes:

  • Abdominal ultrasound or CT: Hepatomegaly, ascites
  • Hepatic Doppler: Reduced or reversed portal flow
  • Chest imaging: Pulmonary edema or pleural effusions if applicable

Published Guidelines

Reference these authoritative sources in your appeal:

  • FDA prescribing information
  • European Society for Blood and Marrow Transplantation (EBMT) guidelines
  • American Society of Hematology (ASH) recommendations

Medical Necessity Letter Structure

Your transplant specialist should structure the medical necessity letter using this framework:

Problem Statement

"[Patient name] is a [age]-year-old with [underlying condition] who underwent HSCT on [date] using [conditioning regimen]. On post-transplant day [X], the patient developed severe VOD/SOS with [organ dysfunction details]."

Clinical Evidence

Document the diagnosis using established criteria:

  • Baltimore criteria: Bilirubin ≥2 mg/dL plus 2 of: hepatomegaly, ascites, weight gain >5%
  • McDonald criteria: Similar but with specific pediatric modifications
  • Organ dysfunction: Specific evidence of renal or pulmonary involvement

Treatment Rationale

"Defitelio is the only FDA-approved therapy for severe VOD/SOS with organ dysfunction. Without treatment, mortality exceeds 70-80%. Clinical trials demonstrate improved Day +100 survival (38-45% vs. historical 21-25%)."

Dosing and Monitoring Plan

"Recommended dosing: 6.25 mg/kg IV every 6 hours (total 25 mg/kg/day) for minimum 21 days. Monitor for bleeding complications and hypotension per FDA guidance."

Note: Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing denial letters, plan policies, and clinical notes to draft point-by-point rebuttals aligned to payer requirements.

Peer-to-Peer Review Support

If Aetna questions the medical necessity, your physician can request a peer-to-peer review with an Aetna medical director.

Preparation Checklist

  • Case summary: 2-3 sentences covering diagnosis, timeline, organ dysfunction
  • Guideline references: FDA approval, EBMT/ASH recommendations
  • Mortality data: Emphasize >70% mortality without treatment
  • Availability windows: Offer specific times for the review call

Key Talking Points

  1. FDA indication match: Severe VOD/SOS with organ dysfunction post-HSCT
  2. No alternatives: Defitelio is the only approved therapy
  3. Urgency: Delay increases mortality risk significantly
  4. Complete documentation: All required evidence submitted

From our advocates: We've seen cases where incomplete organ dysfunction documentation led to initial denials, but patients who worked with their transplant teams to compile comprehensive lab trends and imaging studies successfully overturned decisions on appeal. The key is demonstrating clear evidence of renal or pulmonary involvement alongside the VOD/SOS diagnosis.

Frequently Asked Questions

How long does Aetna prior authorization take for Defitelio?

Standard PA decisions take 30-45 days, but you can request expedited review (72 hours) for urgent cases by documenting that delay would seriously jeopardize health.

What if Defitelio isn't on Aetna's formulary?

Request a formulary exception by demonstrating medical necessity and lack of therapeutic alternatives. Include documentation that Defitelio is the only FDA-approved treatment for severe VOD/SOS.

Can I appeal if my HSCT was performed outside Illinois?

Yes, Illinois appeal rights apply to all Aetna members residing in Illinois, regardless of where treatment occurred. Include complete transplant records from the treating facility.

Does step therapy apply to Defitelio?

Step therapy typically doesn't apply since Defitelio is the only FDA-approved treatment for severe VOD/SOS with organ dysfunction. If step therapy is required, document that supportive care has failed.

What happens if I miss the appeal deadline?

Contact the Illinois Department of Insurance immediately. In some cases, exceptions may be granted for good cause, such as not receiving proper notice of appeal rights.

How do I get help with the appeal process?

Contact the Illinois Department of Insurance consumer assistance line at 1-877-850-4740 or the Attorney General's Health Care Helpline at 1-800-386-5438 for free guidance.
