How to Use This Decision Tree

This guide helps patients and families navigate Spinraza coverage with Blue Cross Blue Shield plans in New Jersey, primarily Horizon Blue Cross Blue Shield. Answer each question honestly based on your current medical situation, then follow the specific action steps for your category.

Important: This applies to fully-insured commercial and NJ FamilyCare plans. Medicare Advantage and self-funded employer plans may have different requirements.

Eligibility Triage: Do You Qualify?

Diagnosis Requirements

✓ Do you have confirmed 5q spinal muscular atrophy (SMA)?

  • Genetic testing showing biallelic SMN1 gene mutations
  • SMA Type I, II, or III diagnosis from a neurologist
  • For Type II/III: symptom onset at ≥6 months of age

✓ Do you retain meaningful motor function?

  • Ability to manipulate objects, sit independently, or walk
  • NOT completely paralyzed or requiring permanent ventilation
  • Documented on standardized scales (CHOP INTEND, HFMSE, 6MWT)

Treatment History Check

✓ Are you treatment-naive for SMA therapies?

  • Have NOT received Zolgensma gene therapy
  • Are NOT currently taking Evrysdi (risdiplam)
  • No concurrent SMA disease-modifying treatments

Required Lab Work

✓ Do you have current lab results?

  • Platelet count within normal limits
  • Coagulation studies (PT/PTT)
  • Quantitative urine protein testing
  • All must be obtained before each dose

If "Likely Eligible" - Your Action Plan

Document Checklist

Medical Records Package:

  • Genetic test results confirming 5q SMA
  • Baseline motor function assessment (within 6 months)
  • Current lab work: platelets, coagulation, urine protein
  • Neurologist's clinical notes supporting medical necessity
  • Insurance card and member ID

Submission Process:

  1. Provider submits PA request via MagellanRx portal or phone: 1-800-424-4508
  2. Include all documentation - incomplete requests cause delays
  3. Track status through provider portal
  4. Expect decision within 5-7 business days
  5. If approved, schedule treatment with certified infusion center
Tip: Have your neurologist emphasize retained motor function and potential for benefit in the medical necessity letter. Include specific motor scale scores and comparison to natural disease progression.

Expected Timeline

  • PA submission to decision: 5-7 business days
  • Urgent/expedited requests: 24-48 hours (requires clinical urgency documentation)
  • First treatment scheduling: 1-2 weeks after approval

If "Possibly Eligible" - Tests You Need

Missing Genetic Confirmation?

Order SMN1 deletion/mutation analysis through:

  • Neurogenetics laboratories
  • Commercial labs (Quest, LabCorp) with SMA panels
  • Timeline: 2-3 weeks for results

Unclear Motor Function Status?

Schedule formal motor assessment:

  • CHOP INTEND for infants/non-sitters
  • HFMSE for children who can sit
  • 6-Minute Walk Test for ambulatory patients
  • Must be performed by trained evaluator

Lab Work Needed?

Order baseline studies:

  • Complete blood count with platelets
  • PT/PTT coagulation studies
  • Quantitative 24-hour urine protein or spot urine protein/creatinine ratio
  • Valid for 30 days before treatment

Re-apply timeline: 4-6 weeks once all documentation is complete.

If "Not Yet" - Alternative Paths

Step Therapy Requirements

Some Horizon BCBS plans may require trying Evrysdi (risdiplam) first. Document why oral therapy is inappropriate:

  • Swallowing difficulties
  • Feeding tube incompatibility
  • Prior Evrysdi failure or intolerance
  • Clinical urgency requiring immediate treatment

Advanced Disease Considerations

If you have significant motor function loss:

  • Document any retained voluntary movement
  • Emphasize potential to prevent further decline
  • Include caregiver quality-of-life considerations
  • Consider compassionate use arguments

Concurrent Therapy Issues

If you've had Zolgensma: Coverage is typically denied due to overlapping mechanisms. Prepare for:

  • Exception request based on incomplete response
  • Time gap between treatments (verify policy requirements)
  • Alternative funding through manufacturer programs

If Denied - Appeals Strategy

Internal Appeals (First Level)

Timeline: Must file within 180 days of denial letter Process:

  1. Submit written appeal to address on denial letter
  2. Include additional clinical documentation
  3. Request peer-to-peer review with plan's medical director
  4. Decision within 30 days (15 days for expedited)

External Review Through IHCAP

When to use: After exhausting internal appeals or if plan waives requirement Timeline: File within 4 months of final internal denial

IHCAP Process:

  1. Submit application to Maximus IHCAP portal
  2. Include required documents:
    • Final internal denial letter
    • Medical records supporting necessity
    • Signed authorization for records release
  3. Independent medical review by specialist physicians
  4. Decision within 45 days (expedited if urgent)
  5. No cost to patient - insurers pay all fees

From our advocates: We've seen families succeed with Spinraza appeals by focusing on the "retained motor function" requirement. One composite case involved a child whose initial denial cited "advanced disease," but the family's neurologist provided detailed HFMSE scores showing meaningful voluntary movement. The external review overturned the denial, emphasizing that any retained function could benefit from treatment. This illustrates the importance of thorough motor function documentation.
