What Drives Vimizim Costs

Vimizim (elosulfase alfa) is an enzyme replacement therapy for MPS IVA (Morquio A syndrome) that carries one of the highest price tags in medicine. The weight-based dosing of 2 mg/kg weekly means costs vary dramatically—from approximately $700,000 annually for a 25 kg patient to over $2.1 million for larger adults.

Key Cost Factors:

  • Specialty tier placement: UnitedHealthcare typically places Vimizim on the highest formulary tier, resulting in 20-40% coinsurance rather than fixed copays
  • Prior authorization requirements: Universal across all UnitedHealthcare plans, adding administrative hurdles
  • Site-of-care restrictions: Must be administered in approved healthcare settings, not at home
  • Quantity limits: Strict dosing protocols based on weight and FDA labeling
Note: Even with insurance coverage, patient responsibility can exceed $100,000-$400,000 annually without additional assistance programs.

Understanding Your UnitedHealthcare Benefits

Before starting Vimizim, investigate your specific benefit structure to understand potential costs and coverage limitations.

From Our Advocates: "We've seen families successfully layer multiple assistance programs—manufacturer copay cards, foundation grants, and hospital charity care—to reduce annual costs from $200K+ to under $5,000. The key is applying early and to multiple sources, as many programs have limited annual funding that gets allocated first-come, first-served."

Peer-to-Peer Review Request

"I'm Dr. [Name] requesting a peer-to-peer review for my patient [Name], member ID [number]. We received a denial for Vimizim for confirmed MPS IVA. This is the only FDA-approved treatment for this rare genetic condition. When can I speak with your medical director? This is time-sensitive as the patient needs weekly infusions."

FAQ

How long does UnitedHealthcare prior authorization take for Vimizim in Florida? Standard prior authorization decisions are made within 14 days, but urgent requests (when delay could jeopardize health) are processed within 72 hours. Submit through the provider portal for fastest processing.

What if Vimizim is non-formulary on my UnitedHealthcare plan? Request a formulary exception with medical necessity documentation. Since there are no alternative treatments for MPS IVA, exceptions are often approved when properly documented.

Can I get expedited appeals in Florida? Yes, if waiting for treatment could seriously jeopardize your health. Both internal and external appeals can be expedited, with decisions required within 72 hours.

Does step therapy apply to Vimizim? Unlikely, since Vimizim is the only FDA-approved enzyme replacement therapy for MPS IVA. However, UnitedHealthcare may require documentation that supportive care alone is insufficient.

What if I lose commercial insurance and switch to Medicare? You'll lose eligibility for BioMarin's copay assistance program but may qualify for Medicare Part D's catastrophic coverage and other foundation programs that accept government insurance beneficiaries.

How much does the BioMarin copay program cover? The program has an annual maximum that varies by year and isn't publicly disclosed. Contact BioMarin RareConnections at 1-866-906-6100 for current limits and eligibility.

Can I appeal based on cost alone? Appeals must be based on medical necessity, not just cost. However, you can request formulary exceptions or tier changes if less expensive alternatives aren't medically appropriate.

What happens if I miss an appeal deadline in Florida? You may lose the right to that level of appeal, but you can still request external review if you missed internal deadlines due to insurer error or extraordinary circumstances.
