Why Michigan State Rules Matter

Michigan's insurance laws provide strong protections for patients seeking specialty medications like Trikafta. The state's Patient's Right to Independent Review Act ensures you have recourse when Humana denies coverage, while Michigan's prior authorization standards create automatic approval timelines that work in your favor.

Key Michigan advantages:

  • Automatic approval for specialty drug PA requests if Humana doesn't respond within 7 days (72 hours for urgent requests)
  • 127-day window to file external review with Michigan DIFS
  • 72-hour expedited external review for urgent medical needs
  • Strong continuity-of-care protections during plan transitions

These protections apply to most Humana plans in Michigan, though self-funded employer plans may have different rules under federal ERISA law.


Humana Prior Authorization Requirements

Trikafta typically requires prior authorization under Humana Medicare Advantage and Part D plans. While specific PA criteria aren't publicly detailed in Humana's formulary documents, industry standards for CFTR modulators generally require:

Coverage at a Glance

Requirement What It Means How to Document
CF diagnosis Confirmed cystic fibrosis ICD-10 code E84.x series
CFTR genotype ≥1 F508del or responsive mutation Genetic testing results
Age requirement ≥2 years (varies by mutation) Date of birth, medical records
Baseline labs Liver function tests ALT, AST, bilirubin within 30 days
Prior failures Step therapy documentation Chart notes of previous treatments

To verify current requirements: Call Humana Pharmacy at 1-866-488-5995 or use their provider PA search tool.


Step-by-Step: Fastest Path to Approval

1. Verify Coverage (Patient/Clinic)

  • Call Humana member services to confirm Trikafta's formulary status
  • Check if your plan requires step therapy through other CF medications
  • Timeline: Same day
  • Document: Insurance card, member ID

2. Gather Required Documentation (Clinic)

  • CFTR genetic testing results showing F508del or responsive mutation
  • Baseline liver function tests (ALT, AST, bilirubin)
  • Documentation of prior CF therapies tried and outcomes
  • Timeline: 1-3 days
  • Submit via: Humana provider portal or fax to PA department

3. Submit Prior Authorization (Prescriber)

  • Complete Humana's PA form with medical necessity justification
  • Include FDA labeling citations supporting use for patient's genotype
  • Timeline: 7 days for standard determination
  • Track via: Humana provider portal

4. Follow Up on Decision (Clinic/Patient)

  • Monitor for approval or denial notice
  • If no response within 7 days, coverage is automatically approved under Michigan law
  • Timeline: Automatic approval if no response by day 8
From our advocates: We've seen Michigan patients successfully appeal Trikafta denials by emphasizing the state's automatic approval rules when Humana missed their 7-day response deadline. Document your submission date and follow up promptly if you don't hear back within the required timeframe.

Michigan's Turnaround Standards

Michigan law establishes clear timelines that protect patients from delayed coverage decisions:

Standard Prior Authorization

  • 7 calendar days for non-urgent requests
  • Automatic approval if insurer doesn't respond within deadline
  • 60-day minimum validity period for approved PAs

Urgent/Expedited Requests

  • 72 hours for urgent medical needs
  • Automatic approval if no response within 72 hours
  • Requires physician documentation of urgency

Renewal Requirements


Step Therapy Protections

If Humana requires step therapy (trying other CF medications first), Michigan law provides several override pathways:

Medical Exception Criteria

You can bypass step therapy if:

  • Clinical stability: Switching would cause deterioration
  • Therapeutic failure: Previous required medications failed
  • Contraindications: Step therapy drugs are medically inappropriate

Documentation for Override

Your physician should document:

  • Specific clinical reasons why preferred medications won't work
  • Prior trial results with step therapy drugs
  • Risk of clinical deterioration with medication changes

Key phrase for appeals: "Patient is clinically stable on current regimen and switching to formulary alternatives would jeopardize therapeutic gains achieved."

Frequently Asked Questions

How long does Humana prior authorization take in Michigan? Humana has 7 calendar days for standard PA decisions and 72 hours for urgent requests. Under Michigan law, if they don't respond within these deadlines, your request is automatically approved.

What if Trikafta isn't on Humana's formulary? You can request a formulary exception through Humana's coverage determination process. Your physician must document why formulary alternatives would be less effective or cause adverse effects.

Can I request expedited review for Trikafta appeals? Yes, if delay would seriously jeopardize your health or ability to regain function. You'll need a physician letter documenting the medical urgency and potential harm from delayed treatment.

Does step therapy apply if I've been stable on Trikafta from another state? Michigan's continuity-of-care protections may allow you to continue current therapy during plan transitions. Document your clinical stability and prior authorization history from your previous plan.

What happens if Michigan DIFS overturns Humana's denial? The decision is binding. Humana must provide coverage as directed by the Independent Review Organization, and you'll receive written notice of the approval.

How much does Trikafta cost without insurance? The list price is approximately $26,000 per month (~$312,000 annually). Vertex offers patient assistance programs that can significantly reduce out-of-pocket costs for eligible patients.
