Working with Your Doctor: Visit Preparation

Before your appointment, prepare a comprehensive overview of your LAL-D journey. Your doctor needs specific details to build a strong prior authorization case.

Bring This Documentation:

  • Complete symptom timeline (when symptoms started, how they've progressed)
  • All previous treatments attempted and their outcomes
  • Current medications and dosages
  • Recent lab results showing liver enzymes (ALT/AST) and lipid levels
  • Any hospitalizations or emergency visits related to LAL-D
  • Insurance card and policy information
Tip: Create a one-page summary of your medical history. This helps your doctor quickly understand your case and saves appointment time for discussing the prior authorization strategy.

Questions to Ask Your Doctor:

  • "What specific documentation does Aetna typically require for Kanuma approval?"
  • "Can you help me understand the weight-based dosing for my case?"
  • "What's your experience with Aetna prior authorizations for rare disease medications?"
  • "If we get denied, will you support a peer-to-peer review?"

Building Your Evidence Kit

Strong documentation significantly improves approval chances. Counterforce Health helps patients and clinicians turn insurance denials into targeted, evidence-backed appeals by identifying specific denial reasons and crafting point-by-point rebuttals aligned with each plan's own rules.

Essential Clinical Evidence:

  • LAL enzyme activity test results showing deficiency (typically <10% of normal)
  • Genetic testing confirming LIPA gene mutations
  • Liver function tests demonstrating hepatic abnormalities
  • Lipid panels showing elevated cholesterol/triglycerides
  • Imaging studies (ultrasound, CT) if showing hepatic changes

Treatment History Documentation:

  • Previous medications tried for lipid management
  • Dietary interventions attempted
  • Any adverse reactions to other treatments
  • Documentation of disease progression despite standard care

Supporting Literature: Your doctor should reference these in the medical necessity letter:

Medical Necessity Letter Essentials

A well-crafted medical necessity letter is crucial for approval. Here's what your doctor should include:

Required Components:

  1. Patient identification (name, DOB, insurance ID, ICD-10 codes)
  2. Clear LAL-D diagnosis with supporting test results
  3. Clinical rationale for Kanuma specifically
  4. Previous treatment failures or contraindications
  5. Weight-based dosing justification per FDA guidelines
  6. Risk of disease progression without treatment
  7. Supporting literature and guideline references

Sample Letter Structure:

[Patient Name] has confirmed LAL-D based on:
- LAL enzyme activity: [X]% of normal (reference: >20%)
- Genetic testing: [specific LIPA mutations]
- Clinical presentation: [hepatomegaly, elevated ALT/AST, dyslipidemia]

Standard lipid-lowering therapies have been inadequate because [specific reasons]. 
Sebelipase alfa at 1 mg/kg every 2 weeks is FDA-approved for this indication 
and represents the only enzyme replacement therapy for LAL-D.

Without treatment, [patient] faces risk of progressive liver disease and 
cardiovascular complications.
Clinician Corner: Include specific lab values, imaging findings, and cite the FDA label for dosing rationale. Reference published studies showing clinical benefit in LAL-D patients.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn
"Not medically necessary" Submit detailed clinical documentation showing LAL-D confirmation and disease severity
"Experimental/investigational" Cite FDA approval for LAL-D and include FDA label
"Step therapy required" Document inadequacy of standard lipid therapies for enzyme deficiency
"Non-formulary medication" Request formulary exception with medical necessity documentation
"Incorrect dosing" Provide weight-based calculation per FDA guidelines
"Site of care issues" Confirm infusion center meets Aetna network requirements

If You Receive a Denial: Don't panic. Many initial denials are overturned on appeal with proper documentation. Contact Counterforce Health for assistance turning your denial into a targeted appeal that addresses Aetna's specific concerns.

Frequently Asked Questions

How long does Aetna prior authorization take for Kanuma in Ohio? Standard reviews take 30-45 days. Expedited reviews (for urgent medical situations) are completed within 72 hours. Submit requests at least 2 weeks before needed treatment.

What if Kanuma isn't on my Aetna formulary? You can request a formulary exception with medical necessity documentation. Your doctor must demonstrate that formulary alternatives are inappropriate for LAL-D enzyme replacement.

Can I request an expedited appeal in Ohio? Yes, if delay would seriously jeopardize your health. Both Aetna and Ohio's external review process offer expedited timelines (72 hours) for urgent cases.

Does step therapy apply to rare disease medications? Aetna may require documentation that standard treatments are inappropriate. For LAL-D, enzyme replacement is first-line therapy, but you may need to document inadequacy of lipid-lowering medications.

What happens if Ohio external review upholds the denial? The IRO decision is binding on Aetna. However, you retain rights to seek other remedies, including regulatory complaints or legal action if appropriate.

How do I find LAL-D testing in Ohio? LabCorp offers LAL testing with locations throughout Ohio. Dried blood spot testing is the preferred method.

From Our Advocates A composite example: One Ohio family faced initial denial for their child's Kanuma therapy despite clear LAL-D diagnosis. By working with their pediatric metabolic specialist to document enzyme deficiency levels, genetic testing results, and progressive hepatic changes, they successfully appealed the decision within 60 days. The key was providing complete diagnostic documentation and citing FDA approval for pediatric LAL-D treatment.
