What Affects Naglazyme Approval Timing

Several factors influence how quickly UnitedHealthcare approves Naglazyme (galsulfase) for MPS VI patients in North Carolina:

Benefit Structure Impact:

  • Medicare Part B: Subject to step therapy requirements as of 2025, adding 3-5 days for exception review
  • Commercial plans: Standard prior authorization through OptumRx with automated screening for complete submissions
  • Existing users: Those with documented use within 365 days are typically exempt from step therapy delays

Documentation Completeness: Complete submissions with enzyme assay results, genetic testing, and specialist notes can be approved within the standard 15-day window. Incomplete submissions trigger additional information requests, extending the timeline by 7-14 days.

Clinical Complexity: Cases requiring peer-to-peer physician review or site-of-care justification for hospital infusions add 5-10 business days to the standard timeline.

Pre-Submission Preparation (0-2 Days)

Essential Documentation Checklist

Diagnostic Requirements:

  • ✅ Enzyme assay results: Deficient N-acetylgalactosamine-4-sulfatase (arylsulfatase B) activity
  • ✅ Genetic testing report: Pathogenic ARSB gene mutations confirming MPS VI
  • ✅ ICD-10 diagnosis code: E76.29 (Other mucopolysaccharidosis)

Clinical Documentation:

  • ✅ Baseline functional assessments: 6-minute walk test, pulmonary function tests
  • ✅ Urinary GAG levels: Initial and monitoring results

Getting Help with Complex Cases

For patients facing repeated denials or complex coverage situations, specialized support is available. Counterforce Health helps patients, clinicians, and specialty pharmacies turn insurance denials into targeted, evidence-backed appeals by analyzing denial letters, plan policies, and clinical notes to identify specific denial reasons and draft point-by-point rebuttals aligned to each payer's own rules. Their platform pulls the right citations for medications—FDA labeling, peer-reviewed studies, and specialty guidelines—and weaves them into appeals with required clinical facts and operational details payers expect.

The system produces letters that meet procedural requirements for coverage determinations, redeterminations, and external review while tracking deadlines and required documentation. This can be particularly valuable for complex rare disease cases like MPS VI, where multiple clinical criteria must be precisely documented for approval.
