How to Get Spinraza (nusinersen) Covered by UnitedHealthcare in Michigan: Complete PA Guide and Appeals Process

Quick Answer: Getting Spinraza Covered by UnitedHealthcare in Michigan

UnitedHealthcare requires prior authorization (PA) for Spinraza (nusinersen) with strict genetic and clinical documentation. Submit genetic confirmation of 5q SMA, baseline motor function scores (HFMSE/RULM), and neurologist prescription through the UHC provider portal. If denied, you have 180 days for internal appeals, then 127 days for Michigan external review through DIFS. First step today: Contact your neurologist to gather genetic testing results and schedule baseline motor assessments while they submit the PA request.

Formulary Status & Tier Placement

Spinraza appears on Tier 2 of UnitedHealthcare formularies with prior authorization and specialty pharmacy requirements. This placement indicates coverage is available but requires clinical justification and utilization management.

Coverage Requirements Summary

Requirement Details Source
Prior Authorization Required for all plan types UHC Policy
Specialty Pharmacy Must use OptumRx specialty network UHC Formulary Guidelines
Genetic Testing 5q SMA confirmation mandatory UHC Clinical Policy
Prescriber Requirement SMA-expert neurologist UHC PA Criteria
Concurrent Therapy No other SMN-modifying drugs UHC Policy

Prior Authorization Requirements

UnitedHealthcare's PA criteria for Spinraza are comprehensive and strictly enforced. Understanding these requirements upfront dramatically improves approval chances.

Initial Therapy Requirements

Genetic Documentation

  • Confirmed diagnosis of 5q spinal muscular atrophy
  • Biallelic SMN1 gene deletion or mutation on chromosome 5q
  • Laboratory report from certified genetic testing facility

Clinical Requirements

  • Diagnosis confirmed by or in consultation with neurologist specializing in SMA
  • Baseline motor function assessment using validated scales:
    • HFMSE (Hammersmith Functional Motor Scale Expanded)
    • RULM (Revised Upper Limb Module)
    • CHOP INTEND (for infants)
    • HINE-2 (for young children)
  • Dosing per FDA-approved labeling
  • Initial authorization limited to 4 loading doses maximum

Continuation Therapy Requirements

For ongoing coverage, UnitedHealthcare requires documented clinical response from baseline using standardized assessments:

  • HINE-2: Net positive improvement in motor milestones
  • HFMSE: At least 3-point increase from baseline
  • RULM: At least 2-point increase from baseline
  • CHOP INTEND: At least 4-point increase from baseline

Specialty Pharmacy Network

Spinraza must be dispensed through UnitedHealthcare's specialty pharmacy network, primarily OptumRx specialty services. This ensures proper handling of the medication and required clinical monitoring.

Key Requirements

  • Prescription routed automatically to specialty pharmacy
  • Patient enrollment and education provided
  • Coordination with infusion center for intrathecal administration
  • Ongoing monitoring for platelet counts, coagulation studies, and urine protein
Tip: Your neurologist's office should coordinate specialty pharmacy enrollment, but you can call OptumRx directly at 800-310-6826 to verify status and delivery timing.

Cost-Share Dynamics

While we can't provide specific cost advice, understanding UnitedHealthcare's general coverage structure helps with planning:

Typical Structure

Appeals Playbook for Michigan

If UnitedHealthcare denies your Spinraza PA request, Michigan provides strong appeal rights under the Patient's Right to Independent Review Act.

Internal Appeals Process

Level 1: Reconsideration

  • Timeline: Submit within plan-specified period (typically 180 days for commercial plans)
  • Process: UHC reviews original decision with any new evidence
  • Duration: Standard review within 15 business days; expedited within 72 hours

Level 2: Formal Internal Appeal

  • Required if Level 1 unsuccessful
  • Include comprehensive medical documentation
  • Consider peer-to-peer review with medical director
  • Final internal decision triggers external review rights

External Review Through Michigan DIFS

After UnitedHealthcare's final internal denial, Michigan law provides independent review:

Standard External Review

  • Timeline: File within 127 days of final adverse determination
  • Process: Michigan Department of Insurance and Financial Services (DIFS) assigns Independent Review Organization (IRO)
  • Duration: Decision within 60 days (often faster)
  • Contact: DIFS at 877-999-6442

Expedited External Review

  • Timeline: 72 hours for decision
  • Requirement: Physician letter certifying delay would seriously jeopardize health
  • Trigger: Document how delayed Spinraza access risks motor function decline
From our advocates: We've seen Michigan external reviews succeed when families submit comprehensive motor function data showing disease progression alongside genetic confirmation. The key is demonstrating both medical necessity under the plan's own criteria and the urgency of treatment to prevent irreversible decline.

Common Denial Reasons & Solutions

Denial Reason Required Evidence Action Steps
Insufficient genetic documentation Complete 5q SMA genetic testing report Request full lab report from testing facility; ensure SMN1 deletion/mutation clearly documented
Missing baseline motor assessments HFMSE, RULM, CHOP INTEND, or HINE-2 scores Schedule evaluation with trained neurologist; document testing conditions and evaluator credentials
Non-specialist prescriber SMA expert neurologist prescription Obtain referral to neurologist with documented SMA expertise; include CV or credentials if helpful
Concurrent SMN therapy Documentation of no overlapping treatments Provide medication list; confirm no Evrysdi or Zolgensma use; document washout period if applicable
Step therapy not completed Trial/failure of Evrysdi or contraindication Document Evrysdi trial outcomes or medical contraindications; provide clinical rationale for Spinraza first-line
