Set Your Goal: Understanding What Approval Requires

Getting Mepsevii covered by Blue Cross Blue Shield Michigan isn't just about filling out forms—it's about building a compelling medical case with your healthcare team. Your partnership with your prescribing physician is the cornerstone of success.

Coverage Requirements at a Glance

Requirement What It Means Where to Find It
Prior Authorization Pre-approval needed before coverage BCBSM PA List
Confirmed MPS VII Diagnosis Beta-glucuronidase deficiency + genetic testing Lab results, genetic counselor reports
Specialist Prescriber Metabolic disease or genetics specialist Provider credentials, referral documentation
FDA-Approved Dosing 4 mg/kg IV every 2 weeks FDA Prescribing Information
Medical Necessity Documentation Functional decline, quality of life impact Clinical notes, assessments, patient reports

Your role is to ensure your doctor has everything needed to make the strongest possible case for medical necessity.

Preparing for Your Provider Visit

Before meeting with your prescribing physician, organize your medical history to support the prior authorization request. This preparation saves time and ensures nothing important gets overlooked.

Create Your Symptom Timeline

Document your MPS VII progression:

  • When symptoms first appeared (joint stiffness, respiratory issues, hepatosplenomegaly)
  • How symptoms have worsened over time
  • Functional limitations that have developed (mobility, endurance, daily activities)
  • Impact on quality of life (school, work, social participation)

Compile Treatment History

List all therapies you've tried:

  • Supportive care measures (physical therapy, respiratory support, orthopedic interventions)
  • Symptom management medications and their effectiveness
  • Any adverse reactions or contraindications to other treatments
  • Hospitalizations or emergency visits related to MPS VII
Tip: Bring a one-page summary of your treatment history. This helps your doctor quickly understand what you've tried and why Mepsevii is the appropriate next step.

Building Your Evidence Kit

Your doctor needs comprehensive documentation to support the prior authorization. Help them gather these essential pieces:

Diagnostic Confirmation

  • Enzyme assay results showing beta-glucuronidase deficiency
  • Genetic testing confirming GUSB gene mutations
  • Specialist consultation notes from geneticist or metabolic disease expert

Functional Assessment Data

  • Pulmonary function tests showing respiratory decline
  • 6-minute walk test results demonstrating reduced endurance
  • Joint range of motion assessments
  • Imaging studies (X-rays, echocardiograms, MRIs) showing disease progression

Quality of Life Documentation

  • Patient-reported outcome measures (if your clinic uses standardized tools)
  • School or work performance records showing impact
  • Caregiver burden assessments if applicable

Counterforce Health helps patients and clinicians compile evidence-backed appeals by identifying the specific documentation payers require and organizing it into targeted, policy-aligned requests. Their platform streamlines the process of turning insurance denials into successful approvals.

Medical Necessity Letter Structure

Work with your doctor to ensure the medical necessity letter includes these key components:

Essential Elements Checklist

Patient Information & Diagnosis

  • Full demographics and insurance details
  • ICD-10 code E76.1 (Mucopolysaccharidosis VII)
  • Date of diagnosis and confirming specialist

Clinical Rationale

  • Progressive nature of MPS VII
  • Specific symptoms and functional decline documented
  • Why Mepsevii is medically necessary at this time
  • Expected benefits based on clinical evidence

Treatment History

  • Supportive care measures tried
  • Limitations of current symptom management
  • Why alternative approaches are insufficient

Dosing and Administration Plan

  • FDA-approved dosing: 4 mg/kg IV every 2 weeks
  • Site of care (infusion center, hospital outpatient)
  • Monitoring plan and safety considerations

Supporting References

Clinician Corner: The medical necessity letter should clearly connect the patient's documented decline with the need for enzyme replacement therapy. Avoid generic language—personalize the letter with specific examples of how MPS VII impacts this individual patient.

Supporting Your Doctor During Peer-to-Peer Review

If Blue Cross Blue Shield requests a peer-to-peer review, your doctor will speak directly with their medical director. You can help prepare for this conversation.

Offer Availability Windows

Let your doctor know when you're available for questions during the review process. Sometimes additional patient information is needed quickly.

Prepare a Concise Case Summary

Create a one-page summary for your doctor that includes:

  • Your current functional status
  • Most concerning symptoms
  • How MPS VII affects your daily life
  • Why you need treatment now rather than later

Key Points for Your Doctor to Emphasize

  • Progressive nature of MPS VII without treatment
  • Lack of alternative therapies for the underlying enzyme deficiency
  • FDA approval specifically for MPS VII
  • Individual patient factors that make treatment urgent

After Your Visit: Documentation and Follow-up

What to Save

  • Copy of the prior authorization submission
  • Medical necessity letter
  • All supporting documentation submitted
  • Confirmation of submission (reference numbers, dates)

Portal Communication

Use your patient portal to:

  • Ask for updates on the PA status
  • Submit additional information if requested
  • Clarify any questions from the insurance review

Timeline Tracking

  • Standard review: 5-7 business days
  • Expedited review: 24-48 hours (if urgent medical need)
  • Follow up: If no response within expected timeframe

Maintaining Respectful Persistence

Appropriate Contact Cadence

  • Week 1: Allow processing time
  • Week 2: Polite status inquiry if no response
  • Week 3+: More frequent follow-up if still pending

Escalation Steps

  1. Nurse or medical assistant for routine updates
  2. Provider directly if delays are concerning
  3. Practice manager if communication breaks down
  4. Appeals process if prior authorization is denied
From Our Advocates: We've seen families succeed by maintaining organized records and staying engaged without becoming adversarial. One family created a simple spreadsheet tracking all communications, which helped them identify exactly when to escalate and what information was still needed. This systematic approach led to approval after an initial denial.

Appeals Process for Michigan Patients

If your prior authorization is denied, Michigan law provides strong appeal rights.

Internal Appeal (Step 1)

  • Deadline: 60 days from denial notice
  • Process: Submit written appeal to BCBSM
  • Timeline: 30 days for preservice appeals, 60 days for post-service
  • Required: Original denial letter, updated medical records, physician statement

External Review (Step 2)

  • Deadline: 127 days from final internal denial
  • Process: File with Michigan DIFS
  • Timeline: 56 days standard, 72 hours expedited

When facing insurance denials, Counterforce Health analyzes the specific denial reasons and creates targeted rebuttals using the payer's own policy language, helping patients and doctors turn denials into approvals more effectively.
