BCBS Illinois Policy Overview
Blue Cross Blue Shield of Illinois (BCBSIL) covers Rystiggo under both commercial and Medicaid lines, but prior authorization is mandatory for all plans. The drug uses billing code J2929 (injection, rozanolixizumab-noli, 1 mg) and must be obtained through designated specialty pharmacies.
Plan Types and Coverage
- Commercial HMO/PPO: Prior authorization required with full clinical documentation
- Medicare Advantage: Same PA requirements with additional CMS guidelines

All BCBS Illinois plans follow consistent criteria aligned with FDA labeling, but specific forms and submission processes may vary by line of business. Check your specific plan documents for formulary tier and any additional restrictions.
Medical Necessity Requirements
Coverage at a Glance
| Requirement | What It Means | Documentation Needed | Source |
|---|---|---|---|
| PA Required | Must get approval before filling | Complete PA form via provider portal | BCBSIL PA Code List |
| FDA Indication | Generalized myasthenia gravis only | ICD-10 code G70.00, clinical notes | FDA Label |
| Antibody Status | AChR or MuSK positive | Lab results from CLIA-certified lab | BCBSIL Clinical Criteria |
| Disease Severity | MGFA Class II-IV | MG-ADL score ≥5, neurological exam | Clinical Documentation Requirements |
| Prior Therapies | ≥2 failed standard treatments | Treatment history with dates/outcomes | Step Therapy Policy |
Core Eligibility Criteria
Diagnosis Requirements:
- Confirmed generalized myasthenia gravis with ICD-10 code G70.00
- Positive acetylcholine receptor (AChR) OR muscle-specific kinase (MuSK) antibodies
- MGFA Class II-IV severity rating
- MG-ADL (Activities of Daily Living) score of 5 or higher
Prescriber Requirements:
- Board-certified neurologist
- Clinical consultation notes supporting diagnosis
- Treatment rationale for choosing Rystiggo over alternatives
Step Therapy and Prior Treatment Documentation
BCBS Illinois requires documented failure, intolerance, or contraindication to at least two standard therapies before approving Rystiggo. This follows a logical treatment progression:
Required Prior Treatments
First-Line Therapies (must try at least one):
- Cholinesterase inhibitors (pyridostigmine/Mestinon)
- Corticosteroids (prednisone, methylprednisolone)
Second-Line Therapies (must try at least one):
- Immunosuppressants (azathioprine, mycophenolate, methotrexate)
- IVIG (intravenous immunoglobulin)
- Plasmapheresis/plasma exchange
Documentation Requirements for Each Failed Therapy
For every prior treatment, include:
- Drug name and dosing: Specific medication, dose, frequency
- Duration: How long the patient was on therapy
- Outcome: Lack of efficacy, intolerable side effects, or contraindication
- Clinical notes: Provider documentation of trial and failure/intolerance
- Dates: Start and stop dates for each therapy
Clinician Tip: Document specific reasons for treatment failure. "Patient experienced muscle weakness despite 3 months of pyridostigmine 60mg TID" is stronger than "failed pyridostigmine."
Medical Exception Pathways
If standard step therapy isn't appropriate, document:
- Contraindications: Medical reasons why first-line therapies can't be used
- Drug interactions: Specific medications that preclude standard treatments
- Comorbidities: Conditions that make typical therapies inappropriate
- Previous severe reactions: History of serious adverse events
Quantity Limits and Dosing Restrictions
BCBS Illinois strictly adheres to FDA-approved dosing for Rystiggo coverage.
Approved Dosing Parameters
- Dose: 10 mg/kg subcutaneous infusion
- Frequency: Once weekly for 6 consecutive weeks per treatment cycle
- Authorization period: Typically 16-26 weeks initially, then annual renewal
- Weight-based calculations: Pharmacy will verify dosing matches patient weight
Reauthorization Requirements
- Updated clinical assessment showing continued benefit
- MG-ADL scores demonstrating improvement or stabilization
- Provider attestation of ongoing medical necessity
- Documentation that patient remains antibody-positive
Note: Doses exceeding FDA parameters require exceptional medical justification and are rarely approved without compelling clinical evidence.
Required Diagnostic Evidence
Laboratory Requirements
- Antibody testing: Positive AChR or MuSK antibodies from CLIA-certified laboratory
- Test recency: Results typically must be within 12 months of PA request
- Lab report: Official laboratory documentation with reference ranges
Clinical Assessment Tools
- MGFA Classification: Must document Class II-IV severity
- MG-ADL Scale: Score of 5 or higher typically required
- Neurological examination: Detailed assessment of muscle weakness patterns
- Functional status: Documentation of how MG impacts daily activities
Supporting Diagnostics
While not always required, these can strengthen your case:
- Repetitive nerve stimulation studies showing decremental response
- Single-fiber EMG abnormalities
- Chest imaging (CT/MRI) to evaluate for thymoma
- Pulmonary function tests if respiratory involvement
Specialty Pharmacy Requirements
Rystiggo must be obtained through BCBS Illinois-designated specialty pharmacies and administered in appropriate clinical settings.
Distribution Requirements
- Specialty pharmacy only: Cannot be filled at retail pharmacies
- Prior authorization: Must be approved before specialty pharmacy will dispense
- Cold chain: Requires refrigerated storage and handling
- Site coordination: Specialty pharmacy coordinates delivery to infusion center
Administration Settings
- Initial doses: Typically administered in hospital or infusion center
- Provider supervision: Must be given by healthcare professionals
- Emergency preparedness: Facilities must be equipped to handle infusion reactions
- Patient monitoring: Vital signs and clinical observation during administration
Supporting Clinical Evidence
When building your medical necessity case, include evidence from these authoritative sources:
Primary Evidence Sources
- FDA prescribing information: Official indication and dosing guidelines
- Clinical trial data: RAISE and RAISE-XT study results showing efficacy
- Medical society guidelines: American Academy of Neurology recommendations
- Peer-reviewed literature: Published studies on FcRn inhibitors in MG
How to Cite Evidence Effectively
Include specific citations in your medical necessity letter:
- "Per FDA labeling, Rystiggo is indicated for generalized MG in AChR/MuSK-positive adults"
- "Clinical trials demonstrated significant improvement in MG-ADL scores"
- "AAN guidelines support FcRn inhibitors for refractory generalized MG"
From Our Advocates: We've seen faster approvals when providers include 2-3 specific citations from major neurology journals alongside the FDA indication. Keep citations recent (within 3-5 years) and directly relevant to the patient's clinical situation. This composite approach has helped streamline the review process in similar cases.
Sample Medical Necessity Narrative
Here's a template structure for your medical necessity letter:
Patient Background: "[Patient name] is a [age]-year-old with confirmed generalized myasthenia gravis, diagnosed [date] with positive [AChR/MuSK] antibodies ([specific titer/result]). Current MGFA Class [II/III/IV] with MG-ADL score of [number], demonstrating significant functional impairment."
Prior Treatment History: "Patient has failed adequate trials of [list treatments with dates and outcomes]. Specifically: [detailed failure documentation for each therapy, including dosing, duration, and reason for discontinuation]."
Clinical Rationale: "Rystiggo is FDA-approved for this exact indication and represents the appropriate next step given [patient-specific factors]. The FcRn inhibition mechanism addresses the underlying pathogenic IgG antibodies responsible for this patient's symptoms."
Treatment Goals: "Expected outcomes include improved MG-ADL scores, reduced disease exacerbations, and better functional capacity as demonstrated in clinical trials."

Common Denial Reasons and Solutions
| Denial Reason | How to Fix | Documentation Needed |
|---|---|---|
| Missing antibody results | Submit lab reports | CLIA-certified AChR/MuSK results |
| Insufficient prior therapies | Document additional failures | Treatment history with dates/outcomes |
| Wrong diagnosis code | Correct ICD-10 coding | Use G70.00 for generalized MG |
| Lack of severity documentation | Provide assessment scores | MG-ADL ≥5, MGFA Class II-IV |
| Non-neurologist prescriber | Transfer to specialist | Board-certified neurologist consultation |
| Quantity exceeds limits | Verify weight-based dosing | Patient weight, dose calculations |
When to Request Peer-to-Peer Review
If your initial appeal is denied, request a peer-to-peer consultation with the BCBS medical director. This allows your neurologist to discuss the case directly with the reviewing physician and often resolves complex clinical situations.
