Set Your Goal: What Approval Requires

Getting Xenpozyme (olipudase alfa-rpcp) covered by Humana requires meeting specific medical necessity criteria for acid sphingomyelinase deficiency (ASMD). Your partnership with your healthcare provider is crucial—they'll need to document your diagnosis and create a compelling case for treatment.

Coverage Requirements at a Glance

Requirement What It Means Where to Find It
Confirmed ASMD diagnosis Genetic testing showing SMPD1 mutations OR enzyme activity <10% normal Lab reports from genetics clinic
Clinical documentation Evidence of organ involvement (spleen, liver, lungs) MRI, CT scans, pulmonary function tests
Prior authorization Pre-approval required before treatment Humana provider portal
Site of care May require in-network infusion center Check with Humana member services
Monitoring plan Detailed follow-up schedule for safety/efficacy Provider treatment plan

Your doctor will need to demonstrate that Xenpozyme is medically necessary for your specific case and that you meet Humana's coverage criteria.

Visit Preparation: Building Your Case

Before meeting with your specialist, gather information that strengthens your case for Xenpozyme coverage.

Symptom Timeline Documentation

Create a detailed record of your ASMD symptoms:

  • Onset and progression: When symptoms first appeared and how they've worsened
  • Functional impact: How symptoms affect daily activities, work, or school
  • Organ-specific issues: Breathing difficulties, abdominal pain, fatigue, bleeding/bruising
  • Growth concerns (for pediatric patients): Height/weight percentiles over time

Previous Treatments and Outcomes

Document all therapies you've tried:

  • Supportive care: Medications for symptoms (bronchodilators, lipid management)
  • Surgical interventions: Splenectomy, lung procedures
  • Outcomes: What helped, what didn't work, and any side effects experienced
  • Why alternatives aren't sufficient: Explain limitations of current treatments
Tip: Bring a written summary to your appointment. This helps ensure nothing is forgotten during the discussion.

Evidence Kit: Essential Documentation

Work with your healthcare team to compile comprehensive medical evidence supporting your need for Xenpozyme.

Required Laboratory Evidence

Your doctor will need:

  • Genetic testing results: SMPD1 gene sequencing showing pathogenic mutations
  • Enzyme activity assay: Acid sphingomyelinase activity in blood cells or fibroblasts
  • Baseline organ assessments: Liver function tests, complete blood count, lipid panel
  • Imaging studies: MRI or CT showing spleen/liver enlargement, chest imaging for lung involvement

Clinical Guidelines and References

Your provider should reference current treatment guidelines:

  • FDA prescribing information for Xenpozyme dosing and monitoring
  • ASMD clinical practice guidelines from specialty societies
  • Published clinical trial data (ASCEND studies) demonstrating efficacy
  • Peer-reviewed literature supporting enzyme replacement therapy in ASMD

Medical Necessity Letter Structure

A strong medical necessity letter is your primary tool for Humana approval. Work with your doctor to ensure all key elements are included.

Essential Components

Patient Information Section

  • Full name, date of birth, Humana member ID
  • ICD-10 diagnosis code: E75.24 (Niemann-Pick disease type B)
  • Treating physician credentials and specialty

Diagnosis Confirmation

  • Specific SMPD1 mutations identified or enzyme activity level
  • Clinical presentation consistent with ASMD type B or A/B
  • Exclusion of CNS involvement (if applicable)

Clinical Rationale

  • Current symptoms and organ involvement with quantifiable measures
  • Progressive nature of ASMD without treatment
  • Xenpozyme as the only FDA-approved therapy for non-CNS ASMD
  • Expected benefits based on clinical trial data

Treatment Plan

  • Weight-based dosing schedule per FDA labeling
  • Infusion site and frequency (every 2 weeks)
  • Monitoring plan: organ measurements, pulmonary function, laboratory tests
  • Safety monitoring for infusion reactions
Clinician Corner: Include specific measurements when possible—spleen volume multiples of normal, DLco percentage predicted, platelet counts. Quantifiable data strengthens the medical necessity argument.

Peer-to-Peer Call Support

If Humana requests a peer-to-peer review, help your doctor prepare for this crucial conversation.

Preparation Strategy

Offer Scheduling Flexibility

  • Provide multiple availability windows to your doctor's office
  • Understand that peer-to-peer calls often happen within 1-3 business days of request

Create a Case Summary Help your provider prepare a concise summary covering:

  • Diagnosis confirmation: Date of genetic testing, specific mutations
  • Disease progression: Timeline of symptom development and organ involvement
  • Treatment urgency: Risks of delaying enzyme replacement therapy
  • Monitoring plan: How response will be assessed and safety ensured

Key Talking Points for Your Provider

Your doctor should emphasize:

  • Xenpozyme is the only FDA-approved treatment for non-CNS ASMD
  • Progressive, life-threatening nature of untreated ASMD
  • Clinical trial evidence showing improvement in organ involvement
  • Established monitoring protocols for safety and efficacy assessment

From Our Advocates

A composite example: One ASMD patient in North Carolina initially received a denial for "insufficient genetic documentation" despite having enzyme testing. Working with their specialist, they ordered comprehensive SMPD1 sequencing, which revealed compound heterozygous mutations. The resubmission with complete genetic confirmation was approved within 10 days. This highlights the importance of meeting every specific criterion in payer policies.

FAQ

How long does Humana prior authorization take for Xenpozyme in North Carolina? Standard prior authorization decisions are made within 7 days for prescription drugs. Expedited reviews (for urgent medical needs) must be completed within 72 hours.

What if Xenpozyme is not on Humana's formulary? You can request a formulary exception by demonstrating medical necessity. Your doctor will need to show that formulary alternatives are inappropriate or ineffective for ASMD.

Can I request an expedited appeal if my health is declining? Yes. If waiting for a standard appeal could seriously jeopardize your health or ability to function, request expedited review. Your doctor must provide medical justification for the urgency.

Does step therapy apply to Xenpozyme? Step therapy typically doesn't apply since there are no FDA-approved alternatives for ASMD. However, Humana may require documentation of supportive care attempts.

What happens if my employer plan is self-funded? Self-funded plans aren't subject to North Carolina's external review process. Contact your HR department about the plan's appeal procedures or use federal external review options.

How much does Xenpozyme cost without insurance? The wholesale acquisition cost ranges from approximately $1,515 for a 4mg vial to $7,576 for a 20mg vial. Annual treatment costs can exceed $300,000, making insurance coverage essential.
