Who Should Use This Guide
This guide helps patients, caregivers, and healthcare providers navigate Humana's prior authorization process for Ruconest (C1 esterase inhibitor [recombinant]) in North Carolina. You'll need this if:
- Your doctor prescribed Ruconest for hereditary angioedema (HAE) acute attacks
- Humana denied initial coverage or requires prior authorization
- You're preparing documentation for approval or appeal
- You need to understand North Carolina's external review process
Expected outcome: With complete documentation, most Ruconest approvals are granted within 7-15 business days. If denied, North Carolina's external review process has strong patient protections through Smart NC.
Member & Plan Basics
Verify Your Coverage
Before starting, confirm these details with Humana member services:
- Active coverage status and member ID
- Plan type (Medicare Advantage, commercial, Medicaid)
- Specialty drug benefits and formulary tier
- Deductible status and copay structure
- Prior authorization requirements (most Humana plans require PA for specialty drugs)
Tip: Humana's 2024 Medicare Prior Authorization List confirms Ruconest requires prior authorization. Check your specific plan's formulary for current requirements.
Plan-Specific Considerations
Medicare Advantage members have additional appeal rights under federal law, including expedited reviews for urgent situations. Commercial plan members follow standard prior authorization timelines but can access North Carolina's external review process if denied.
