UnitedHealthcare Policy Overview

UnitedHealthcare covers Mepsevii (vestronidase alfa-vjbk) as a specialty medical benefit across commercial, Medicare Advantage, and Medicaid plans, but prior authorization is required for all plan types with no exceptions for urgent starts. The medication is processed through OptumRx for most commercial plans and requires specific documentation to establish medical necessity.

Coverage by Plan Type

Plan Type Portal Processing Time Special Notes
Commercial OptumRx Provider Portal 5-15 business days No step therapy typically required
Medicare Advantage UnitedHealthcare Provider Portal 5-15 business days (72-hour expedited available) May require additional Medicare forms
Medicaid State-specific portal Varies by state Additional state forms may apply
Note: Verify your specific plan details through the UnitedHealthcare member portal or by calling customer service at 1-800-711-4555, as benefit structures can vary.

Medical Necessity Requirements

Confirmed MPS VII Diagnosis

UnitedHealthcare requires definitive diagnosis confirmation through one of these methods:

  • β-glucuronidase enzyme assay showing activity below 10% of normal range
  • GUSB genetic testing identifying disease-causing mutations
  • Urinary GAG levels (supportive evidence if enzyme/genetic testing unavailable)

The diagnosis must be documented with ICD-10 code E76.29 (Mucopolysaccharidosis, unspecified).

Specialist Documentation

Coverage requires prescription by a metabolic specialist or geneticist who provides:

  • Consultation note confirming MPS VII diagnosis
  • Treatment goals and monitoring plan
  • Patient's current weight for weight-based dosing calculations
  • Documentation of multisystem involvement typical of MPS VII

Counterforce Health helps patients and clinicians compile the specific evidence UnitedHealthcare requires, turning complex medical documentation into targeted, policy-aligned appeals that address each coverage criterion systematically.
