Set Your Goal: What Approval Requires

Getting Lumizyme approved by Blue Cross Blue Shield of Illinois requires meeting specific clinical criteria and following their prior authorization process. Here's what you and your doctor need to accomplish together:

Coverage Requirements at a Glance

Requirement What It Means Where to Find It
Prior Authorization Must be approved before treatment BCBSIL Specialty Drug List
Confirmed Diagnosis Pompe disease with enzyme + genetic testing Medical records from specialist
Specialist Involvement Neurologist, cardiologist, or pulmonologist Provider network directory
Billing Code J0221 for alglucosidase alfa 10 mg BCBSIL PA Code List
Site of Care Approved infusion center Provider administered therapy rules

Your partnership with your physician is crucial because they'll need to submit the prior authorization request, write the medical necessity letter, and potentially participate in a peer-to-peer review if initially denied.

Note: Lumizyme costs approximately $993 per 50-mg vial according to Sanofi's wholesale acquisition cost, making thorough documentation essential for approval.

Prepare for Your Provider Visit

Before your appointment, organize your medical history and functional status to help your doctor build the strongest possible case.

Create Your Symptom Timeline Document when symptoms began, how they've progressed, and their impact on daily activities:

  • Muscle weakness patterns (proximal vs. distal)
  • Respiratory symptoms (shortness of breath, sleep issues)
  • Cardiac involvement (if applicable)
  • Mobility changes over time

List All Previous Treatments Your doctor needs to know what you've tried before Lumizyme:

  • Physical therapy duration and outcomes
  • Respiratory support devices used
  • Other medications attempted
  • Reasons for discontinuation (ineffective, side effects, contraindications)

Prepare Functional Impact Notes Be specific about how Pompe disease affects your life:

  • Activities you can no longer perform
  • Work or school limitations
  • Need for assistive devices
  • Quality of life changes

This information helps your doctor justify medical necessity and address potential step therapy requirements.

Build Your Evidence Kit

Work with your healthcare team to gather comprehensive documentation that supports your need for Lumizyme.

Essential Laboratory Evidence Your diagnosis must be confirmed with both:

  • Enzyme assay results showing GAA deficiency (typically <40% of normal activity)
  • Genetic testing identifying pathogenic GAA gene mutations
Clinician Corner: Most insurance plans require documented evidence of both biochemical GAA deficiency and molecular confirmation of pathogenic GAA variants prior to authorizing enzyme replacement therapy coverage.

Functional Assessment Documentation Request copies of recent assessments including:

  • 6-minute walk test results (measures ambulatory function)
  • Pulmonary function tests (FVC, MIP, MEP with percent predicted values)
  • Muscle strength assessments using MRC scale or quantitative measurements
  • Cardiac evaluations if applicable

Treatment History Summary Compile records showing:

  • Previous therapy attempts and outcomes
  • Contraindications to alternative treatments
  • Progressive decline despite supportive care
  • Specialist recommendations for enzyme replacement therapy

Structure the Medical Necessity Letter

The medical necessity letter is often the most critical component of your prior authorization request. Help your doctor include these key elements:

Required Components Checklist

  • Patient identification (name, DOB, insurance ID)
  • ICD-10 diagnosis code for Pompe disease
  • Detailed clinical history and current status
  • Laboratory confirmation (enzyme and genetic testing results)
  • Previous treatment history and failures
  • Clinical rationale for Lumizyme specifically
  • Planned dosing regimen (typically 20 mg/kg every 2 weeks)
  • Monitoring plan for safety and efficacy
  • Specialist involvement documentation

Sample Letter Structure

testing findings]. Current functional status shows [specific 
measurements from 6MWT, PFTs, muscle strength assessments].

[Specialist name and credentials] will monitor treatment with planned 
dosing of [amount] every two weeks. Monitoring protocols include

and specialist recommendations.

Respectfully requesting approval for this medically necessary therapy.

Support Your Doctor's Peer-to-Peer Review

If Blue Cross Blue Shield requests a peer-to-peer review, you can help your doctor prepare for this crucial conversation.

Offer Scheduling Flexibility Medical directors typically have limited availability windows. Let your doctor know you're flexible with timing to accommodate these calls, which often occur within 24-72 hours of the request.

Prepare a Concise Case Summary Help your doctor create a one-page summary including:

  • Key diagnostic findings
  • Functional decline measurements
  • Treatment failures and contraindications
  • Urgency factors (respiratory compromise, progressive weakness)

Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing denial letters, plan policies, and clinical notes to draft point-by-point rebuttals aligned to each plan's specific requirements.

Document Everything After Your Visit

Maintaining thorough records protects your appeal rights and tracks progress through the approval process.

Save These Documents

  • Prior authorization submission confirmation
  • All correspondence with Blue Cross Blue Shield
  • Provider portal messages and responses
  • Peer-to-peer review notes
  • Any denial letters or approval notifications

Use Patient Portal Messaging When following up with your doctor's office:

  • Reference specific dates and submission details
  • Ask for copies of all submitted documentation
  • Request updates on review timelines
  • Confirm receipt of any additional information requests

Practice Respectful Persistence

Insurance approvals often require follow-up, but maintaining professional relationships is essential.

Appropriate Follow-Up Cadence

  • Week 1-2: Allow normal processing time
  • Week 3: Gentle inquiry about status
  • Week 4+: More frequent contact if approaching treatment deadlines

Escalation Strategy If your doctor's office seems overwhelmed:

  1. Offer to help gather additional documentation
  2. Ask about engaging a patient advocate or case manager
  3. Consider involving specialty pharmacy support services
  4. Contact Blue Cross Blue Shield member services directly for status updates

Remember that your healthcare team wants to help you access necessary treatment, but they're managing multiple complex cases simultaneously.
