Set Your Goal: Understanding Humana's Requirements

Aldurazyme (laronidase) requires prior authorization under Humana's 2025 Medicare formularies for the treatment of Mucopolysaccharidosis Type I (MPS I). Success depends on partnering effectively with your healthcare provider to demonstrate medical necessity.

Coverage Requirements at a Glance

Requirement What It Means Documentation Needed
Confirmed MPS I Diagnosis Genetic or enzymatic testing required IDUA enzyme assay results, genetic testing
Specialist Involvement MPS I or lysosomal storage disease expert Letter from qualified specialist
Baseline Assessments Disease severity documentation 6-minute walk test, pulmonary function, echocardiogram
Monitoring Plan Safety protocol for IV infusions Detailed infusion monitoring protocol
Dosing Compliance FDA-approved 0.58 mg/kg weekly Weight-based calculation documentation

Preparing for Your Provider Visit

Come prepared with a comprehensive symptom timeline and treatment history to help your doctor build the strongest possible case.

Before Your Appointment

Document Your Symptom Timeline:

  • Age when symptoms first appeared
  • Specific manifestations (joint stiffness, breathing difficulties, heart problems, vision changes)
  • How symptoms have progressed or worsened over time
  • Impact on daily activities and quality of life

Treatment History Summary:

  • Previous therapies attempted (if any)
  • Results, side effects, or reasons for discontinuation
  • Current medications and their effectiveness
  • Any hospitalizations or surgeries related to MPS I
Tip: Bring a written summary—this helps ensure nothing important gets missed during your appointment and gives your provider documentation to reference.

Building Your Evidence Kit

Your provider will need comprehensive clinical evidence to support the prior authorization request.

Essential Laboratory Documentation

Diagnostic Confirmation:

Baseline Disease Assessments:

  • 6-minute walk test results to document functional capacity
  • Pulmonary function tests (especially forced vital capacity)
  • Echocardiogram showing cardiac involvement
  • Joint range of motion measurements
  • Audiometry and ophthalmologic exams

Clinical Guidelines and References

Your provider should reference established treatment guidelines in the medical necessity letter. Key resources include:

The Medical Necessity Letter Structure

A well-structured medical necessity letter follows this framework:

1. Patient and Diagnosis

  • Clear statement of MPS I diagnosis with subtype (Hurler, Hurler-Scheie, or Scheie)
  • Supporting laboratory evidence (enzyme activity, genetic results)
  • ICD-10 code: E76.01 (Hurler's syndrome) or E76.02 (Hurler-Scheie syndrome) or E76.03 (Scheie's syndrome)

2. Clinical Rationale

  • Current disease manifestations and severity
  • Baseline functional assessments demonstrating impairment
  • How Aldurazyme addresses the underlying pathophysiology

3. Treatment Plan and Monitoring

4. Risk of Delay

  • Progressive nature of MPS I without treatment
  • Irreversible organ damage if therapy is delayed
  • Impact on quality of life and functional decline
Clinician Corner: Include specific references to peer-reviewed literature and FDA labeling. Quantify functional impairments where possible (e.g., "6-minute walk distance of X meters, below 5th percentile for age").

Supporting Peer-to-Peer Reviews

If Humana requests a peer-to-peer review, help your provider prepare by:

Offering Scheduling Flexibility:

  • Provide multiple availability windows
  • Confirm contact information for the review call

Preparing a Concise Case Summary:

  • One-page bullet points covering diagnosis, severity, and treatment rationale
  • Key lab values and functional assessments readily available
  • Specific questions or concerns Humana raised in their initial review

Key Discussion Points:

  • Emphasize the lack of alternative treatments for MPS I
  • Highlight the progressive, debilitating nature without intervention
  • Reference published outcomes data for enzyme replacement therapy

After Your Visit: Documentation and Follow-up

What to Save

  • Copy of the prior authorization request submitted to Humana
  • Medical necessity letter from your provider
  • All supporting documentation (lab results, imaging, assessments)
  • Confirmation of submission (fax confirmation, portal receipt)

Portal Communication

Use your patient portal to:

  • Request copies of clinical notes from your visit
  • Ask for updates on the prior authorization status
  • Submit additional information if requested by Humana

Timeline Expectations

  • Standard prior authorization decisions: typically within 30 days
  • Expedited requests (if urgent): within 72 hours
  • Follow up if no response within expected timeframes

Appeals and Respectful Persistence

If Your Initial Request is Denied

Step 1: Internal Appeal with Humana

  • File within 65 days of the denial notice for Medicare Advantage
  • Submit additional clinical evidence addressing specific denial reasons
  • Request expedited review if clinically urgent

Step 2: Smart NC External Review If Humana's internal appeal is unsuccessful, North Carolina residents have strong external review rights through Smart NC.

FAQ

How long does Humana prior authorization take for Aldurazyme in North Carolina? Standard decisions typically take up to 30 days. Expedited requests for urgent medical situations must be decided within 72 hours.

What if Aldurazyme is non-formulary on my Humana plan? Non-formulary medications can still be covered through the prior authorization process if medical necessity is demonstrated. Focus on documenting why Aldurazyme is essential for treating your MPS I.

Can I request an expedited appeal if my condition is worsening? Yes. Both Humana internal appeals and North Carolina external reviews offer expedited timelines for urgent medical situations. Include a physician statement explaining why delay would jeopardize your health.

What counts as adequate specialist involvement? Humana typically requires involvement from a physician specializing in MPS I, lysosomal storage diseases, or related fields such as medical genetics or pediatric metabolism.

Do I need to try other treatments first (step therapy)? Step therapy requirements are uncommon for ultra-rare diseases like MPS I, as there are no alternative FDA-approved enzyme replacement therapies for this condition.

What if I've been stable on Aldurazyme but need reauthorization? Document continued clinical benefit through follow-up assessments (repeat 6-minute walk tests, pulmonary function, cardiac evaluations) and absence of significant adverse effects.
