How to Get Kanuma (Sebelipase Alfa) Covered by UnitedHealthcare in Texas: Complete Prior Authorization and Appeals Guide

Quick Answer: Getting Kanuma Approved by UnitedHealthcare in Texas

Kanuma (sebelipase alfa) requires prior authorization from UnitedHealthcare/OptumRx for lysosomal acid lipase deficiency (LAL-D). Success depends on: confirmed LAL-D diagnosis (enzyme assay or genetic testing), documented disease severity (elevated liver enzymes, dyslipidemia), and evidence that supportive therapies are insufficient. First step: Have your specialist submit the Texas Standard PA Request Form with complete diagnostic documentation. If denied: Request peer-to-peer review and file internal appeal within 180 days. Texas residents can access independent external review through TDI if internal appeals fail.

Step-by-Step: Fastest Path to Approval

1. Confirm Diagnosis and Gather Evidence

Who: Your specialist (hepatologist, geneticist, or metabolic specialist) Timeline: 1-2 weeks What to collect:

  • LAL enzyme activity assay showing <10% normal activity
  • LIPA genetic testing results (if available)
  • Recent liver function tests (ALT, AST, GGT)
  • Complete lipid panel
  • Liver imaging (ultrasound or MRI)

2. Document Disease Severity and Prior Treatments

Who: Your medical team Timeline: 1 week Required documentation:

  • Evidence of hepatic involvement (elevated transaminases, hepatomegaly)
  • Lipid abnormalities (elevated LDL-C, low HDL-C)
  • History of supportive treatments tried (statins, dietary modifications)
  • Growth charts (for pediatric patients)

3. Submit Texas Standard PA Request

Who: Prescribing specialist How: Texas Standard PA Form via UHC provider portal Timeline: Submit within 72 hours of gathering documentation Mark urgent if delay could jeopardize health

4. Follow Up on Decision

Timeline: 72 hours for standard requests, 24 hours for urgent Next steps: If approved, coordinate with specialty pharmacy. If denied, immediately request peer-to-peer review.

Required Documentation

Core Clinical Evidence

Diagnostic Confirmation

  • LAL enzyme assay: Must show markedly reduced activity (<5-10% of normal range)
  • Genetic testing: Pathogenic or likely pathogenic LIPA gene variants
  • Clinical phenotype: Compatible symptoms and lab findings

Disease Severity Markers

  • Liver involvement: ALT ≥1.5× upper limit of normal, hepatomegaly on imaging
  • Lipid abnormalities: Elevated LDL-C, triglycerides; reduced HDL-C
  • Growth/nutritional status: Especially important in pediatric cases

Medical Necessity Letter Checklist

Clinician Corner: Your medical necessity letter should address each of these points with specific patient data and citations to FDA labeling and UHC's own enzyme replacement policy.
  • Confirmed LAL-D diagnosis with specific test results
  • Evidence of active disease (elevated enzymes, lipid abnormalities)
  • Prior supportive treatments and their limitations
  • Why Kanuma is the only disease-modifying therapy available
  • Expected clinical benefits and monitoring plan
  • Dosing rationale consistent with FDA labeling

Common Denial Reasons & Solutions

Denial Reason How to Overturn Documentation Needed
"Insufficient diagnostic evidence" Submit complete enzyme assay and/or genetic testing Lab reports with reference ranges, genetic counselor interpretation
"Lack of medical necessity" Demonstrate disease severity and inadequate response to supportive care Serial liver function tests, lipid panels, imaging showing progression
"Missing specialist evaluation" Ensure PA submitted by appropriate subspecialist Metabolic specialist, hepatologist, or geneticist consultation notes
"Exceeds quantity limits" Provide weight-based dosing calculation per FDA label Patient weight, dose calculation, vial requirements
"Alternative treatments not tried" Document supportive care attempts and limitations Treatment history with statins, dietary modifications, outcomes

When to Escalate

Contact Texas regulators if:

  • UnitedHealthcare misses decision deadlines (72 hours standard, 24 hours urgent)
  • Appeal rights are not properly explained
  • External review access is denied or obstructed

Frequently Asked Questions

How long does UnitedHealthcare prior authorization take in Texas? Standard PA decisions are typically made within 72 hours of complete submission. Urgent requests marked by the prescriber are decided within 24 hours.

What if Kanuma is non-formulary on my plan? Kanuma is typically covered on UnitedHealthcare/OptumRx formularies as a specialty drug. If it appears non-formulary, request a formulary exception using the Texas Standard PA Form.

Can I request an expedited appeal? Yes. Both internal appeals and Texas external reviews can be expedited if delay would seriously jeopardize your health. Your prescriber must certify the urgency.

Does step therapy apply to Kanuma? No. UnitedHealthcare's policies recognize that Kanuma is the only FDA-approved enzyme replacement therapy for LAL-D, so no step therapy against another ERT is required. However, you may need to document that supportive treatments (statins, dietary modifications) are insufficient.

What happens if I move from another state to Texas? Texas residents have stronger external review rights than many states. If you had a denial in another state, you can request a new PA in Texas and potentially access the Texas IRO process if denied.

How often do I need reauthorization? Most UnitedHealthcare policies require reauthorization every 6-12 months, with evidence of clinical response (improved liver enzymes, lipid levels, or stabilized disease progression).
