How to Use This Decision Tree

This guide helps you navigate Humana's prior authorization requirements for Emgality in Michigan. Start with the eligibility triage below, then follow your specific pathway. Each section includes actionable steps, required documents, and official forms with direct links.

Eligibility Triage: Do You Qualify?

Answer these questions to determine your approval likelihood:

  • Migraine diagnosis confirmed by neurologist or headache specialist
  • ≥4 migraine days per month (documented in headache diary)
  • Failed 2+ preventive medications at therapeutic doses for 3+ months each

❌ Not Yet Eligible if ANY apply:

  • No documented migraine diagnosis
  • <2 migraine days per month

If "Likely Eligible": Your Action Plan

Step 1: Gather Required Documentation

Before your prescriber submits the prior authorization:

  • Migraine diary: 3 months showing ≥4 migraine days/month with severity ratings
  • Prior medication records: Names, doses, duration, and specific reasons for discontinuation
  • Clinic notes: Neurological exam findings and migraine impact assessment
  • Insurance information: Humana member ID and current formulary tier

Step 2: Prescriber Submits Prior Authorization

Your doctor will submit through Humana's provider portal or fax with:

  • Medical necessity letter citing FDA labeling and migraine guidelines
  • ICD-10 diagnosis code (G43.909 for migraine, unspecified)
  • Documentation of step therapy failures
  • Proposed dosing: 240mg loading dose, then 120mg monthly

Timeline: Humana responds within 72 hours (standard) or 24 hours (expedited for urgent cases).

Step 3: Monitor and Follow Up

  • Check approval status via Humana member portal
  • If approved: Coordinate with specialty pharmacy for delivery
  • If denied: Proceed to appeals process (see section below)

If "Possibly Eligible": Tests and Tracking

Strengthen Your Case:

  1. Request neurology referral if diagnosed by primary care
  2. Start comprehensive migraine diary tracking frequency, severity, and triggers
  3. Complete adequate preventive trials (minimum 3 months each at therapeutic dose)
  4. Document functional impact with validated tools like MIDAS or HIT-6

Timeline to Reapply:

  • 3-6 months after completing additional preventive trials
  • 1-3 months for neurology consultation and specialized testing

If "Not Yet": Alternatives and Exceptions

  • Other CGRP inhibitors: Aimovig (erenumab), Ajovy (fremanezumab), or Qulipta (atogepant) may have different coverage criteria
  • Botox for chronic migraine: Often covered with fewer restrictions for ≥15 headache days/month
  • Generic preventives: Build your step therapy history with topiramate, propranolol, or amitriptyline

Exception Requests:

File for medical necessity exception if you have:

  • Contraindications to all required step therapy medications
  • Severe medication allergies or intolerances
  • Urgent clinical need due to migraine-related disability

If Denied: Michigan Appeals Process

Michigan offers robust appeal rights with specific timelines and forms.

Level 1: Internal Appeal with Humana

Deadline: 65 days from denial notice Process: Submit additional documentation addressing specific denial reasons Timeline: 7 days for Part D appeals, up to 30 days for Medicare Advantage

Level 2: Michigan DIFS External Review

Deadline: 127 days from Humana's final denial (longer than federal 120-day standard) Forms: DIFS Form FIS 0018 Cost: Free to consumers Timeline: 60 days standard, 72 hours expedited

Submit via:

  • Online at Michigan DIFS external review portal

From our advocates: We've seen Michigan DIFS external reviews succeed when patients include detailed migraine diaries showing functional impact alongside pharmacy records documenting step therapy failures. The key is demonstrating that Emgality meets medical necessity criteria that weren't properly considered in the initial denial.
