How to Get Emgality Covered by Blue Cross Blue Shield of Michigan: Prior Authorization Forms, Appeal Process, and Timeline

Quick Answer: Getting Emgality Approved in Michigan

Blue Cross Blue Shield of Michigan (BCBSM) requires prior authorization for Emgality (galcanezumab) with specific medical criteria. You'll need documented failure of at least two traditional migraine preventives (typically topiramate and propranolol) plus a detailed migraine diary showing ≥15 headache days monthly. Submit requests via CoverMyMeds, fax to 1-866-601-4425, or call 1-800-437-3803. If denied, Michigan's DIFS external review process gives you 127 days to appeal with binding outcomes within 60 days (72 hours for urgent cases).

First step today: Contact your prescriber to document your migraine frequency and prior treatment failures, then initiate the PA request through your provider.

What This Guide Covers

This guide helps Michigan patients and their healthcare providers navigate Blue Cross Blue Shield of Michigan's prior authorization process for Emgality (galcanezumab-gnlm), a CGRP inhibitor used for migraine prevention. We'll walk through BCBSM's specific requirements, submission processes, and what to do if your initial request is denied.

Who this helps:

  • Patients with chronic migraines (≥15 headache days/month)
  • Those who've failed traditional preventive medications
  • Providers submitting PA requests for CGRP inhibitors
  • Anyone facing an Emgality denial from BCBSM

Based on a 2024 Michigan DIFS external review case, BCBSM has strict medical policy criteria that must be met for approval, even after patients have tried multiple other medications.

Check Your Plan Type

  • Commercial plans: Follow standard PA process

Confirm Emgality's Status

BCBSM typically places Emgality on a higher formulary tier requiring prior authorization. Check your specific plan's Clinical Drug List to confirm coverage status.

Clinician Corner: Medical Necessity Documentation

When submitting PA requests for Emgality, include:

Problem Statement

  • Chronic migraine diagnosis with ICD-10 code
  • Frequency and severity documentation
  • Impact on daily functioning

Prior Treatment History

  • Specific medications tried (topiramate, propranolol, etc.)
  • Doses, duration, and outcomes
  • Reasons for discontinuation

Clinical Rationale

  • Why Emgality is medically necessary
  • Expected outcomes and monitoring plan
  • References to FDA labeling or guidelines
From our advocates: We've seen the strongest approvals when providers include a detailed timeline showing exactly how long each prior medication was tried, the maximum tolerated dose, and specific reasons for failure. A simple statement like "failed topiramate due to cognitive side effects after 8 weeks at 100mg daily" carries much more weight than "topiramate ineffective."

FAQ

How long does BCBSM prior authorization take for Emgality? Standard review takes up to 15 business days. Expedited reviews for urgent cases are completed within 24-72 hours.

What if Emgality isn't on my formulary? You can request a formulary exception through the same PA process, providing medical necessity documentation and evidence of failed formulary alternatives.

Can I get an expedited appeal in Michigan? Yes, if delay would seriously harm your health. You'll need a physician letter documenting the urgency. DIFS expedited external reviews are decided within 72 hours.
