Coverage Basics: Is Vimizim Covered by Humana?

Vimizim (elosulfase alfa) is covered by Humana across all plan types in Illinois, including Medicare Advantage, commercial plans, and Medicaid managed care. However, prior authorization is universally required due to the medication's high cost (approximately $700,000-$2.1 million annually) and specialized nature.

From our advocates: "We've seen the best outcomes when families work closely with their specialist's office to submit comprehensive documentation upfront. One family we worked with had their initial PA approved in just 8 days by including baseline functional assessments, detailed genetic testing results, and a thorough treatment plan. Taking time to gather complete documentation initially often prevents delays and denials later."
