Before You Start: Plan Verification

  3. Medical vs. pharmacy benefit: Vimizim is usually covered under the medical benefit for infusion administration
  4. In-network status: Verify your prescribing specialist and infusion site are in Cigna's network
Tip: Call Cigna member services at the number on your insurance card to confirm these details before starting the authorization process.

Gather Required Documentation

Core Requirements for Cigna Vimizim Authorization

Based on Cigna's 2024 coverage policy, you'll need:

Requirement Documentation Needed Where to Obtain

Age requirement Documentation showing patient ≥5 years old Medical records
Baseline functional assessment 6-minute walk test results Treating physician, physical therapy

Diagnostic Confirmation Details

GALNS enzyme testing: Must show absent or markedly reduced N-acetylgalactosamine 6-sulfatase activity in cultured fibroblasts or leukocytes. Normal ranges vary by lab, but significant reduction typically means activity levels in the 0-7 range.

From our advocates: "We've seen Washington patients successfully overturn Vimizim denials by ensuring their metabolic specialist clearly documents baseline functional measurements and treatment goals. The key is having complete diagnostic confirmation upfront—either enzyme testing showing reduced GALNS activity or genetic confirmation of biallelic mutations. When families gather this documentation before submitting, approval rates improve significantly."
