What Affects Garadacimab Approval Timing

Several factors influence how quickly UnitedHealthcare approves Garadacimab (Andembry) for hereditary angioedema (HAE) prophylaxis in North Carolina:

Benefit Type: Garadacimab falls under the specialty pharmacy benefit managed by OptumRx, requiring prior authorization through their dedicated portal rather than standard medical benefits.

Complexity of Criteria: UnitedHealthcare mandates step therapy, meaning you must document trial and failure of preferred HAE prophylaxis medications like danazol, tranexamic acid, or berotralstat (Orladeyo) before approving Garadacimab.

Documentation Completeness: Missing clinical records, incomplete prior therapy documentation, or absent specialist prescriptions can delay approval by 3-7 additional business days while reviewers request supplemental information.

Note: Garadacimab does not require a REMS program, simplifying the approval process compared to other specialty medications that need additional safety training documentation.
