What This Guide Covers

This comprehensive guide helps Pennsylvania patients and their healthcare providers navigate Aetna CVS Health's prior authorization process for Kesimpta (ofatumumab), a monthly self-injected treatment for relapsing forms of multiple sclerosis.

Whether you're newly diagnosed or switching from another MS therapy, this guide provides the specific forms, documentation requirements, and timelines you need to get coverage approved. We'll also cover Pennsylvania's powerful new external review program, which has successfully overturned 50% of insurance denials in its first year.

Before You Start: Verify Your Coverage

Check Your Plan Type and Formulary Status

Call CVS Caremark at 1-800-294-5979 (Monday-Friday, 8 AM-6 PM CST) with your Aetna member ID to verify:

  • Formulary tier (typically Tier 3-4 specialty)
  • Step therapy requirements (prior DMT trials needed)
  • Quantity limits (3 pens first month, 1 monthly thereafter)
  • Site of care restrictions (specialty pharmacy dispensing)
Pennsylvania Advantage: Fully insured Aetna members in Pennsylvania are exempt from step therapy requirements under state law, which can streamline your approval process.

Confirm Your MS Diagnosis Qualifies

Kesimpta is FDA-approved for relapsing forms of MS in adults, including:

  • Clinically isolated syndrome (CIS)
  • Relapsing-remitting MS (RRMS)
  • Active secondary progressive MS (SPMS)

Primary progressive MS is not covered. Your neurologist must confirm a relapsing phenotype with ICD-10 code G35.

Pennsylvania's External Review Advantage

Pennsylvania launched an Independent External Review program in January 2024 that has proven remarkably effective for overturning insurance denials.

How Pennsylvania's Process Works

Eligibility: After receiving your "Final Adverse Benefit Determination" from Aetna's internal appeal process, you have four months to request external review.

Success Rate: In 2024, 50.1% of external reviews were decided in favor of patients, resulting in coverage for previously denied treatments.

Timeline:

  • Submit request: Online at pa.gov/reviewmyclaim or call 1-877-881-6388
  • Eligibility confirmation: Within 5 business days
  • Independent review: Decision within 45 days (72 hours for expedited)
  • Final decision: Binding on the insurance company
From Our Advocates: We've seen Pennsylvania patients successfully overturn Kesimpta denials through external review by submitting comprehensive clinical records and emphasizing the drug's FDA approval for relapsing MS. The key is thorough documentation of disease activity and prior treatment failures.

Important Limitations

Pennsylvania's external review applies only to commercial insurance (not self-funded employer plans). Check with your employer's HR department to confirm your plan type.

Renewal and Re-authorization

When to Start Your Renewal

Begin the re-authorization process 60-90 days before your current approval expires. Aetna typically authorizes Kesimpta for 12-month periods.

Renewal Documentation

  • Updated neurologist letter documenting treatment response
  • Recent MRI showing disease stability or improvement
  • Medication adherence records (≥85% compliance)
  • Any new safety monitoring results

Evidence of Treatment Success:

  • Reduction in relapse rate compared to pre-treatment
