How to Get Mavenclad (Cladribine Tablets) Covered by Cigna in Michigan: Complete Prior Authorization and Appeals Guide

Quick Answer: Getting Mavenclad Covered by Cigna in Michigan

Cigna requires prior authorization for Mavenclad (cladribine tablets) with strict step therapy requirements - you must have failed two disease-modifying therapies (DMTs) or one high-efficacy agent like Ocrevus or Tysabri. Your neurologist submits the PA via Cigna's provider portal with documentation of MS diagnosis, prior therapy failures, and baseline lymphocyte counts. If denied, you have 180 days for internal appeals, then 127 days for Michigan's DIFS external review. Start today: Contact your neurologist to begin gathering prior therapy records and schedule baseline labs.

Common Denial Reasons & How to Fix Them

"Inadequate Prior Therapy Documentation"

Fix: Submit detailed pharmacy records or prescription history showing:

  • Exact medication names and dosages
  • Duration of each trial (minimum 3-6 months typically required)
  • Specific reasons for discontinuation with dates

"Step Therapy Not Met"

Fix: Document failures of required alternatives:

  • Two traditional DMTs (interferons, glatiramer acetate, oral agents)
  • OR one high-efficacy agent with clear rationale for discontinuation
  • Include allergy documentation or contraindication notes

"Not Medically Necessary"

Fix: Strengthen clinical justification with:

  • Recent MRI showing new or enhancing lesions
  • Documentation of clinical relapses despite treatment
  • Functional disability progression (EDSS scores)
  • Peer-reviewed literature supporting Mavenclad use

Appeals Process in Michigan

If Cigna denies your Mavenclad prior authorization, Michigan law provides strong patient protections through a two-tier system.

Internal Appeals (First Step)

Timeline: 180 days from denial date
Process: Submit written appeal to Cigna with additional evidence
Response time: 30 days (expedited: 72 hours with physician urgency letter)

Key strategies for internal appeals:

  • Request peer-to-peer review between your neurologist and Cigna's medical director
  • Submit additional clinical evidence not in original request
  • Include patient impact statement describing functional limitations

External Review Through Michigan DIFS

Timeline: 127 days after final internal denial
Process: Independent medical review by external experts
Response time: 60 days standard, 72 hours expedited

To file an external review:

  1. Complete Michigan's external review form online or by mail
