Eligibility Triage: Do You Qualify?

Likely Eligible ✅

You probably qualify if you have all of these:

  • Confirmed MPS IVA diagnosis with documented reduced GALNS enzyme activity in blood/fibroblasts
  • Genetic confirmation showing pathogenic GALNS gene mutations
  • Baseline functional measures (6-minute walk test showing >30 meters walked)
  • Specialist prescriber (geneticist, metabolic specialist, or pediatric neurologist)
  • Age requirement met (typically 5+ years old, verify with current Cigna policy)

Possibly Eligible ⚠️

You might qualify but need additional testing if you have:

  • Clinical suspicion of MPS IVA but incomplete diagnostic workup
  • Family history of Morquio syndrome but no personal testing
  • Some symptoms (skeletal abnormalities, short stature, joint problems) but no enzyme testing
  • Previous testing that was inconclusive or outdated

Not Yet ❌

You'll need to address these first:

  • No confirmed diagnosis of MPS IVA

  • Unable to perform functional testing (too young or severe mobility limitations)
  • No specialist involvement

  • Request through specialized lab (Mayo Clinic, Greenwood Genetic Center)
  • Specify "MPS IVA/Morquio A syndrome suspected"
  • Results typically available in 2-3 business days

Genetic Testing:

  • Full GALNS gene sequencing
  • Include clinical information to support medical necessity
  • Insurance often covers when ordered by genetics specialist

Functional Assessment:

  • Schedule 6-minute walk test at specialist center
  • Document baseline before starting therapy discussions
  • Consider pulmonary function testing if respiratory symptoms present

Timeline for Re-application

  • 2-4 weeks: Complete diagnostic testing
  • 1-2 weeks: Specialist consultation and documentation
  • Submit PA: Once all requirements met

If "Not Yet": Alternative Options

Immediate Steps

Seek Specialist Consultation:

  • Find MPS specialist through National MPS Society provider directory
  • Request referral from primary care physician
  • Consider telehealth consultation if no local specialists

Explore Diagnostic Options:

  • Discuss enzyme testing with current physician
  • Research clinical trials through ClinicalTrials.gov
  • Connect with patient advocacy groups

Financial Planning:

  • Contact BioMarin's patient support program
  • Research foundation grants for rare diseases
  • Explore state Medicaid coverage if eligible

Exception Request Preparation

Even without full qualification, you may request coverage exceptions based on:

  • Severe clinical presentation
  • Lack of alternative treatments
  • Compelling clinical circumstances

If Denied: Pennsylvania Appeal Path

Pennsylvania's new external review system provides strong appeal options for Cigna denials.

Step 1: Internal Appeal (Required First)

Timeline: Must file within 180 days of denial

How to Submit:

  • Call Cigna member services number on your card
  • Submit written appeal through Cigna appeals portal
  • Include additional clinical documentation

Response Time: Cigna has up to 30 days for standard appeals, 72 hours for expedited

Step 2: Pennsylvania External Review

Eligibility: Available after completing Cigna's internal appeal process

How to Apply:

Success Rate: Approximately 50% of external reviews result in coverage approval

Timeline:

  • 15 days to submit additional documentation after assignment
  • 45 days for final decision
  • Expedited reviews decided within 72 hours for urgent cases
From our advocates: "We've seen multiple Pennsylvania Vimizim cases succeed at external review when the initial denial cited 'experimental' status, even though the drug has full FDA approval. The key was submitting comprehensive clinical guidelines and FDA labeling documents that clearly established medical necessity."

Peer-to-Peer Review Option

Before or during appeals, request a peer-to-peer discussion:

  • Ask your specialist to call Cigna's medical director
  • Prepare clinical rationale and guideline citations
  • Document the conversation for appeal records

Can I get expedited review for urgent cases? Yes, both Cigna internal appeals and Pennsylvania external reviews offer expedited timelines for urgent medical situations.
