Renewal Triggers: When to Start the Process

Most Humana plans require prior authorization renewal every 6-12 months for Rystiggo, with some starting at 3-month intervals for initial approvals. The exact timeline depends on your specific plan and initial authorization terms.

Start renewal preparation when:

  • You're 30-45 days before expiration (check your authorization letter for exact dates)
  • Your neurologist notices symptom changes requiring dose adjustments
  • You've experienced significant improvement that supports continued therapy
  • Annual formulary changes occur (typically January 1st)
Tip: Mark your calendar with the authorization end date minus 30 days. Humana's electronic prior authorization system aims for 1-business-day decisions when submitted electronically, but allow extra time for potential documentation requests.

Evidence Update: Documenting Treatment Response

Your renewal success depends on demonstrating clinically meaningful improvement from Rystiggo therapy. The gold standard is the MG-ADL (Myasthenia Gravis Activities of Daily Living) scale.

MG-ADL Score Documentation

What insurers want to see:

  • Baseline MG-ADL from before starting Rystiggo
  • Current MG-ADL showing improvement
  • ≥2-point reduction is considered clinically meaningful; ≥3-point reduction indicates robust response

MG-ADL tracking template:

Baseline (pre-Rystiggo): __/24
Current: __/24  
Change: -__ points
Date ranges: [start] to [current]

Additional Response Measures

Document these supporting measures:

  • QMG (Quantitative Myasthenia Gravis) scores if available (≥3-point improvement meaningful)
  • Steroid dose reductions (e.g., "Prednisone reduced from 20mg to 10mg daily")
  • Reduced rescue therapy (fewer IVIG treatments, hospitalizations)
  • Functional improvements (return to work, driving, social activities)
Note: VA criteria require MGFA class II-IV and MG-ADL ≥5 for approval. Document that you continue to meet these thresholds.

Renewal Packet: Required Documentation

Core Requirements

Medical necessity letter from neurologist including:

  • Current diagnosis (AChR+ or MuSK+ generalized myasthenia gravis)
  • Objective improvement data (MG-ADL, QMG scores)
  • Continued need for therapy
  • Safety monitoring results
  • Why alternative therapies remain inappropriate

Clinical documentation:

  • Recent neurology visit notes
  • MG-ADL assessments
  • Laboratory results (if monitoring required)
  • Hospitalization records (if applicable)

Humana-Specific Requirements

Check your plan's current requirements using Humana's Prior Authorization Lists:

  1. Medicare Advantage plans: Usually require medical benefit prior authorization
  2. Part D plans: May cover under pharmacy benefit with different criteria
  3. Employer plans: Often have plan-specific formulary requirements

Cycles must be spaced ≥63 days apart according to most policies, so document the timing since your last cycle.

Timeline: Submission and Decision Windows

Optimal Submission Timeline

45 days before expiration:

  • Schedule neurologist follow-up
  • Request updated MG-ADL assessment
  • Gather clinical response documentation

30 days before expiration:

  • Submit electronic prior authorization through Humana provider portal
  • Include all supporting documentation
  • Request expedited review if medically urgent

Decision timeframes:

  • Standard: Up to 14 days for Medicare Advantage
  • Expedited: 72 hours if delay would jeopardize health
  • Electronic submissions: Target 1 business day by 2026

If Additional Information is Requested

Humana may request:

  • Peer-to-peer review with medical director
  • Additional clinical documentation
  • Updated laboratory results
  • Clarification on dosing or administration

Respond within 48-72 hours to avoid delays.

If Coverage Lapses: Bridge Options

If your Rystiggo authorization expires before renewal approval, discuss these temporary bridge options with your neurologist:

Rescue Therapy Options

IVIG or plasmapheresis may be used if:

  • You experience significant symptom worsening
  • Risk of myasthenic crisis is present
  • Important: VA criteria require ≥1 month gap between IVIG/PLEX and starting new Rystiggo cycle

Background therapy optimization:

  • Increase pyridostigmine (if tolerated)
  • Temporarily increase corticosteroids
  • Optimize other immunosuppressants
Important: Never stop Rystiggo abruptly without neurologist guidance. The effect wanes gradually, and planning bridge therapy is essential for preventing crisis.

Emergency Coverage

For urgent situations:

  • Hospital coverage: Inpatient IVIG/PLEX typically covered for crisis
  • Emergency authorization: Request expedited appeal citing medical urgency
  • Temporary supply: Some plans provide transition coverage during appeals

Annual Changes: What to Re-verify

January 1st Formulary Updates

Check annually:

  • Tier placement (specialty tier restrictions may change)
  • Prior authorization requirements (criteria may become more restrictive)
  • Quantity limits (dosing restrictions)
  • Step therapy (required trial medications)

Use Humana's Medicare Drug List tool to verify current status.

Plan Design Changes

Verify these elements:

  • Deductible amounts (Part D deductible was $590 in 2025)
  • Coinsurance rates for specialty tier
  • Out-of-pocket maximum ($2,000 for Part D in 2025, $2,100 in 2026)
  • Provider network changes affecting infusion sites

FAQ

How long does Humana take to process Rystiggo renewals? Standard timeline is up to 14 days for Medicare Advantage, but electronic submissions often receive decisions within 1 business day. Submit 30 days early to avoid gaps.

What if my MG-ADL score hasn't improved enough? Document other measures of improvement: reduced hospitalizations, steroid dose reductions, return to activities. Include physician assessment of why continued therapy is medically necessary despite modest MG-ADL changes.

Can I request expedited renewal? Yes, if delay would jeopardize your health. Your neurologist must document medical urgency, such as risk of myasthenic crisis or respiratory compromise.

Does step therapy apply to renewals? Generally no, if you're already established on Rystiggo and responding well. However, verify this hasn't changed in your plan's annual updates.

What if Humana moves Rystiggo to a higher tier? You cannot request tier exceptions for specialty tier drugs. Focus on medical necessity appeals and consider manufacturer assistance programs or foundation grants for cost support.

How often can I get Rystiggo cycles? Most policies require ≥63 days between cycle starts (approximately 9 weeks total). Document clinical need if you require more frequent dosing.

What documentation convinces insurers most? Objective improvement measures (MG-ADL, QMG scores) combined with reduced healthcare utilization (fewer hospitalizations, IVIG treatments) and steroid-sparing effects provide the strongest evidence.

Can I appeal to Michigan if I have Medicare Advantage? Medicare Advantage appeals generally follow federal Medicare rules, but if you have secondary Michigan-regulated coverage or certain employer plans, Michigan DIFS external review may be available. Check your denial letter for applicable appeal rights.

When navigating Rystiggo renewals with Humana, success depends on proactive planning, comprehensive documentation, and understanding both Humana's requirements and Michigan's appeal rights. Counterforce Health's platform can help analyze your specific situation and craft targeted appeals when needed, turning complex insurance policies into actionable strategies.
