UnitedHealthcare's OptumRx requires prior authorization for Kanuma, covering both Wolman disease and cholesteryl ester disease presentations of LAL deficiency. The insurer follows a structured approval process with specific documentation requirements.

Source: UHC enzyme replacement therapy policy

2. Gather Clinical Evidence

Who: Healthcare team
What: Document hepatosplenomegaly, liver function abnormalities, lipid profiles, or disease symptoms
Where: Medical records, recent imaging, lab work
Timeline: Can be completed during routine visits

3. Submit Prior Authorization

Who: Prescribing physician or their staff
How: UnitedHealthcare Provider Portal or call 800-711-4555

Clinician Corner: Medical necessity letters should emphasize the lack of therapeutic alternatives for LAL deficiency. Include specific enzyme activity levels, genetic testing results, and quantified clinical improvements expected (liver function, lipid profiles). Reference the FDA label for dosing rationale and monitoring requirements.

Cost Breakdown and Assistance Options

Kanuma carries one of the highest price tags in specialty pharmacy, with annual costs ranging from $890,000 to $4.9 million depending on patient weight and dosing requirements. U.S. retail pricing averages approximately $998 per mL, making a typical 10 mL vial cost nearly $10,000.

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn Required Documentation
"Diagnosis not confirmed" Submit enzyme testing + genetic results LAL activity <0.5 nmol/hour/mg protein OR LIPA mutations
"Not medically necessary" Document clinical symptoms and disease progression Liver biopsy, imaging showing hepatosplenomegaly, abnormal lipids
"Dosing not appropriate" Align with FDA label by age/weight Prescription matching FDA-approved dosing guidelines
"Inadequate prior therapy documentation" Show supportive care trials Records of lipid-lowering therapy, dietary management attempts

The most effective appeals include peer-reviewed literature supporting enzyme replacement therapy as the only disease-modifying treatment for LAL deficiency, emphasizing the progressive nature of the condition without treatment.

Appeals Process in California

Internal Appeals with UnitedHealthcare

Eligibility: After internal appeal failure or 30-day non-response
Cost: Free to patients
Timeline: 45 days for standard IMR, 7 days for expedited
Success Rate: California IMRs have favorable overturn rates for medically necessary treatments

Required Documents:

  • Internal appeal denial letter
  • Complete medical records
  • Physician statement supporting medical necessity
  • Published literature on LAL deficiency treatment
From Our Advocates: We've seen several LAL deficiency cases succeed at IMR when internal appeals failed. The key was comprehensive documentation showing enzyme deficiency, progressive disease symptoms, and the lack of therapeutic alternatives. Independent reviewers often recognize the unique nature of rare disease treatments that may not fit standard coverage criteria.

Counterforce Health specializes in turning insurance denials into successful appeals by analyzing denial letters, identifying specific coverage criteria, and crafting evidence-based rebuttals. For complex rare disease cases like LAL deficiency, having expert support can significantly improve approval odds by ensuring all clinical and procedural requirements are properly addressed.

Pharmacy Options and Coordination

Specialty Pharmacy Requirements

UnitedHealthcare typically requires Kanuma to be dispensed through their specialty pharmacy network, primarily OptumRx specialty pharmacy services.

Delivery Options:

  • Mail order: Often preferred for ongoing therapy, may offer cost savings
  • Retail specialty: Available for immediate needs or patient preference
  • Provider administration: For clinic-based infusions

Coordination Tips:

  • Confirm specialty pharmacy enrollment before first shipment
  • Verify cold-chain handling requirements
  • Coordinate delivery timing with infusion appointments
  • Keep backup supply protocols in place

Prior Authorization Coordination

Work with your specialty pharmacy to ensure:

  • Authorization transfers properly from retail to specialty
  • Refill timing aligns with authorization periods
  • Any dosing changes trigger PA updates
  • Insurance changes are communicated promptly

Renewal and Long-Term Planning

Annual Authorization Renewal

UnitedHealthcare requires reauthorization every 12 months with documentation of:

  • Clinical response: Improved liver function tests (ALT, AST)
  • Lipid improvements: Reduced LDL cholesterol, triglycerides
  • Continued medical necessity: Ongoing enzyme deficiency
  • Dosing appropriateness: Weight-based adjustments as needed

Budget Planning Considerations

  • Plan year changes: Coverage criteria may be updated annually
  • Formulary shifts: Tier placement can affect costs
  • Copay assistance: Manufacturer programs typically renew annually
  • Maximum out-of-pocket: California's specialty drug cost caps provide some protection

FAQ

How long does UnitedHealthcare prior authorization take for Kanuma in California?
Standard requests: 72 hours. Urgent requests: 24 hours. If UnitedHealthcare doesn't respond within these timeframes, the request is automatically approved.

What if Kanuma is non-formulary on my plan?
You can request a formulary exception through the same prior authorization process. Emphasize that no therapeutic alternatives exist for LAL deficiency.

Can I request expedited appeal if my condition is worsening?
Yes, both UnitedHealthcare internal appeals and California IMR offer expedited processes for urgent medical situations.

Does step therapy apply to Kanuma?
Generally no, since there are no approved alternative enzyme replacement therapies for LAL deficiency. However, documentation of supportive care attempts may be required.

What happens if I move from another state to California?
Your UnitedHealthcare coverage should transfer, but you'll gain access to California's enhanced IMR process if appeals are needed.

How much will I pay out-of-pocket with commercial insurance?
With manufacturer copay assistance, eligible patients may pay $0. Without assistance, costs depend on your plan's specialty tier structure and annual maximums.

Can my doctor provide Kanuma in their office?
Yes, Kanuma can be administered in clinical settings. This may be covered under your medical benefit rather than pharmacy benefit, potentially affecting costs.

What if UnitedHealthcare requires step therapy despite no alternatives existing?
Document the lack of therapeutic alternatives and request an exception. If denied, this is strong grounds for appeal, especially in California's IMR process.
