Coverage at a Glance

Requirement What It Means Where to Find It
Prior Authorization Required before first dose Humana PA List
Genetic Testing 5q SMA confirmation mandatory Lab report with SMN1/SMN2 analysis
Specialist Prescriber Neurologist or neuromuscular specialist Medical necessity letter
Motor Function Assessment Baseline HFMSE, CHOP INTEND, or RULM Clinical documentation

Required Documentation for Approval

Genetic Confirmation (Mandatory)

Humana requires laboratory documentation of confirmed 5q SMA diagnosis showing:

  • Biallelic SMN1 gene mutations (homozygous deletion or compound heterozygous mutations)
  • SMN2 copy number assessment (typically 2-4 copies)
  • Lab report from a certified genetic testing facility

Clinical Assessment Documentation

Your neurologist must provide:

  • Baseline motor function evaluation using validated scales:
    • Hammersmith Functional Motor Scale Extended (HFMSE) for ambulatory patients
    • CHOP INTEND for non-sitter patients
    • Revised Upper Limb Module (RULM) when appropriate
  • Current clinical notes documenting SMA diagnosis and functional status
  • Patient weight for dosing calculations (0.25mg/kg for <20kg; 5mg for ≥20kg)

Treatment History (If Applicable)

  • Documentation of previous SMA treatments and responses
  • Reasons for switching from other therapies
  • Contraindications to alternative treatments

  2. Schedule Motor Function Assessment (Neurologist)
    • Complete baseline HFMSE, CHOP INTEND, or RULM scoring
    • Document current functional status and treatment goals
    • Timeline: Can be done at regular appointment
  3. Obtain Medical Necessity Letter (Neurologist)
    • Include genetic confirmation, functional assessment, and clinical rationale
    • Address any previous treatments and outcomes
    • Timeline: 1-2 business days
  4. Submit Prior Authorization (Neurologist's Office)
  5. Track Authorization Status (Patient/Clinic)
    • Humana must respond within 72 hours for standard requests
    • Check status via provider portal or member services

    • Request expedited review if medically urgent
    • Timeline: 72 hours for expedited appeals

Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn
Missing genetic confirmation Submit complete SMN1/SMN2 testing report from certified lab
Inadequate functional assessment Provide baseline motor function scores using validated scales (HFMSE/CHOP INTEND)
Non-specialist prescriber Transfer care to neurologist or obtain co-signature from neuromuscular specialist
Concurrent SMA therapy Discontinue other SMA drugs and document washout period
Insufficient medical necessity Strengthen prescriber letter with clinical rationale and treatment goals
Missing prior therapy documentation Provide records of previous treatments, failures, or contraindications
Tip: The most common reason for Spinraza denials is incomplete genetic testing documentation. Ensure your lab report clearly shows both SMN1 deletions and SMN2 copy number.

FAQ: Spinraza Coverage by Humana

How long does Humana prior authorization take for Spinraza? Humana must respond within 72 hours for standard requests and 24 hours for expedited requests. Most approvals with complete documentation are processed within 1-2 business days.

What if Spinraza is not on Humana's formulary? You can request a formulary exception through Humana's exception process. Your prescriber must demonstrate that covered alternatives would be less effective or cause adverse effects.

Can I get expedited approval for Spinraza? Yes, if your neurologist documents that standard processing would seriously jeopardize your health or ability to regain function. Expedited requests are decided within 72 hours.

Does step therapy apply to Spinraza in Texas? Humana may require documentation of previous SMA treatments, but true step therapy (trying cheaper alternatives first) is less common for rare disease medications when prescribed by specialists.

What happens if I'm already on Spinraza and switch to Humana? Humana has transition policies for new members already on specialty medications. Contact member services immediately to request a temporary supply while prior authorization is processed.

Can I appeal a Spinraza denial in Texas? Yes, you have 65 days to file an internal appeal with Humana, followed by independent external review through the Texas Department of Insurance if needed.

Do I need a neurologist to prescribe Spinraza? While not always explicitly required, Humana's approval is much more likely when prescribed by a neurologist or neuromuscular specialist who can provide detailed clinical documentation.

How much will Spinraza cost with Humana coverage? Out-of-pocket costs depend on your specific plan. Medicare Part B typically covers 80% after deductible, with supplemental insurance or manufacturer programs helping with remaining costs.
