From Our Advocates

We've seen many Elaprase approvals succeed when families work closely with their MPS specialist to document not just the diagnosis, but the specific functional improvements expected from treatment. One common oversight is failing to include baseline measurements that will be used to track treatment response—this documentation strengthens both initial requests and reauthorization appeals.

FAQ: Your Top Questions Answered

How long does UnitedHealthcare prior authorization take for Elaprase?
Standard requests typically process within 5-7 business days. Expedited requests are decided within 72 hours when medical urgency is documented.

What if Elaprase isn't on my plan's formulary?
Request a formulary exception with strong medical necessity documentation. Since no alternative ERT exists for MPS II, exceptions are often granted with proper clinical justification.

Can I request an expedited appeal in Texas?
Yes, if delays would jeopardize your health. Both UnitedHealthcare internal appeals and Texas external review offer expedited timelines for urgent cases.

Does step therapy apply to enzyme replacement therapies?
It may, depending on your specific plan. However, medical exceptions are commonly approved for rare disease treatments when alternatives are inappropriate or contraindicated.

What happens if I move to Texas from another state?
Your prior authorization may need to be resubmitted under Texas-specific plan requirements. Contact UnitedHealthcare to confirm coverage continuation.

How often do I need reauthorization for Elaprase?
Typically annually, with documentation of treatment response including objective measures like organ size reduction, improved endurance, or airway function.

Can I appeal to Texas Department of Insurance for all UnitedHealthcare plans?
No—ERISA self-funded employer plans, Medicare, and Medicaid follow federal appeal processes. State-regulated commercial plans are eligible for Texas external review.

What if my infusion center isn't in UnitedHealthcare's network?
Request a network adequacy exception if no in-network providers can safely administer Elaprase in your area. Document travel distance and specialized care requirements.
