Required Clinical Evidence

Diagnostic Confirmation:

  • Molecular genetic testing results showing LMNA c.1824C>T mutation (most common) or other confirmed pathogenic variants
  • Clinical photographs documenting characteristic features (if appropriate)
  • Growth velocity charts showing deceleration

Treatment History:

  • Documentation of supportive care measures tried
  • Any previous clinical trial participation
  • Response to other medications or interventions

Current Clinical Status:

  • Recent echocardiogram or cardiac imaging
  • Bone density studies if available
  • Nutritional assessments
  • Developmental milestones (for pediatric patients)

Published Guidelines and References

Your doctor should reference these authoritative sources in the medical necessity letter:

  • FDA prescribing information for Zokinvy (lonafarnib)
  • Progeria Research Foundation clinical guidelines
  • Peer-reviewed studies on farnesyltransferase inhibitors in HGPS
  • American College of Medical Genetics recommendations for rare disease management

Counterforce Health specializes in identifying the right clinical evidence for rare disease appeals, pulling citations from FDA labeling, peer-reviewed studies, and specialty guidelines to create compelling, evidence-backed prior authorization requests.

Medical Necessity Letter Structure

The medical necessity letter is the cornerstone of your prior authorization request. Here's the structure your doctor should follow:

Essential Components

1. Patient Summary and Diagnosis

  • Clear statement of HGPS or progeroid laminopathy diagnosis
  • Genetic testing results with specific mutation identified
  • Current age, weight, height, and BSA calculation

2. Clinical Rationale

  • Explanation of disease progression and prognosis
  • Why Zokinvy is medically necessary for this patient
  • FDA approval status and indication alignment

3. Treatment History and Alternatives

  • Previous therapies attempted and their outcomes
  • Why alternative treatments are insufficient
  • Contraindications to other approaches

4. Risks of Delay

  • Progressive nature of the condition
  • Cardiovascular complications without treatment
  • Impact on quality of life and life expectancy

5. Monitoring Plan

  • Laboratory monitoring schedule (liver function, CBC)
  • Follow-up appointments and assessments
  • Dosing adjustments based on BSA changes
From our advocates: "We've seen the strongest approvals when the letter includes specific quotes from the FDA label showing Zokinvy 'reduces the risk of mortality' in HGPS patients. This direct regulatory language carries significant weight with medical directors reviewing these rare cases."

Key Phrases for Medical Necessity

Your doctor should include these specific phrases:

  • "FDA-approved indication for reducing mortality risk"
  • "No therapeutic alternatives for this orphan indication"
  • "Genetically confirmed diagnosis requires targeted therapy"
  • "Progressive, life-limiting condition without treatment"

Peer-to-Peer Review Support

If Humana requests a peer-to-peer review, you can support your doctor by providing additional context and availability.

Preparing Your Doctor for P2P Calls

Clinical Summary Points:

  • One-page summary of key clinical facts
  • Genetic testing results and implications
  • Previous treatment failures or limitations
  • Urgency factors (disease progression, complications)

Availability Windows:

  • Provide your doctor with flexible scheduling options
  • Ensure they have your contact information for urgent questions
  • Offer to be available during the call if appropriate

Supporting Documentation:

  • Recent photos showing disease progression
  • Quality of life impact statements
  • Family medical history if relevant

P2P Call Script for Providers

Suggest your doctor use this framework:

  1. Opening: "This patient has genetically confirmed HGPS with [specific mutation]"
  2. Medical necessity: "Zokinvy is the only FDA-approved therapy to reduce mortality risk"
  3. Urgency: "The condition is progressive and life-limiting without intervention"
  4. Documentation: "All FDA criteria are met with complete genetic and clinical confirmation"

After Your Visit: Next Steps

Respectful Persistence: Follow-Up Strategy

Maintaining appropriate follow-up without overwhelming your healthcare team requires a strategic approach.

Follow-Up Timeline

Week 1-2: Wait for initial decision (most electronic submissions decided within 1 business day)

Week 3: Contact doctor's office if no update received

Week 4: Request status update from Humana directly

Beyond 30 days: Consider escalation to appeals process

Escalation Scripts

For Doctor's Office: "Hi, I'm following up on my Zokinvy prior authorization submitted on [date]. Has Humana requested any additional information? I'm happy to provide anything needed."

For Humana: "I'm calling about prior authorization request #[number] for Zokinvy submitted on [date]. Can you provide a status update and expected timeline?"

When to Escalate Politely

Contact your doctor's office if:

  • No response after 5 business days
  • Humana requests additional information
  • You receive a denial notice
  • Timeline expectations aren't being met

Remember that persistence shows engagement in your care, but respect your healthcare team's workflow and priorities.

Are there financial assistance programs for Zokinvy? Yes, contact the manufacturer Eiger BioPharmaceuticals for patient assistance programs. The Progeria Research Foundation may also provide guidance on funding resources.

What if I move to Texas from another state? Your Humana coverage should transfer, but you may need to establish care with a new Texas provider familiar with HGPS management and Zokinvy prescribing.

How do I find HGPS specialists in Texas? The Progeria Research Foundation maintains a registry and can help identify Texas providers with HGPS experience. Over 140 doctors in Texas have documented progeria expertise.
