Complete Checklist to Get Nourianz (istradefylline) Covered by Humana in Virginia: Forms, Appeals, and Approval Steps

Answer Box: Getting Nourianz Covered by Humana in Virginia

Nourianz (istradefylline) requires prior authorization from Humana for Parkinson's disease OFF episodes. The fastest path: 1) Confirm your doctor has documented failed trials of other adjunct therapies (amantadine, MAO-B inhibitors, or COMT inhibitors), 2) Submit PA request via Humana's provider portal with detailed OFF episode documentation, and 3) If denied, file internal appeal within 65 days. Virginia residents can pursue external review through federal Medicare appeals (not state review) if internal appeals fail.

From our advocates: We've seen many Nourianz approvals succeed when providers document specific OFF episode patterns—like "patient experiences 2-3 hour morning OFF periods daily despite optimized levodopa timing"—rather than general statements about motor fluctuations. This concrete detail helps reviewers understand the functional impact and medical necessity.
