Why Coverage Myths Persist

Naglazyme (galsulfase) is a life-changing enzyme replacement therapy for MPS VI, but it's also one of the most expensive medications available—costing roughly $600,000 to $1.8 million annually depending on patient weight. This creates a perfect storm for misinformation about insurance coverage.

Many families hear conflicting advice from well-meaning friends, outdated online forums, or even healthcare staff who aren't familiar with UnitedHealthcare's specific requirements. The reality? Coverage decisions follow strict, documented criteria that have nothing to do with luck or "knowing the right person."

Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by identifying the specific denial basis and crafting point-by-point rebuttals aligned to each plan's own rules. Their platform helps patients, clinicians, and specialty pharmacies navigate these complex approval processes with the right documentation and evidence.

Myth vs. Fact: The Top 7 Misconceptions

Myth 1: "If my doctor prescribes Naglazyme, UnitedHealthcare has to cover it"

Fact: UnitedHealthcare requires prior authorization through OptumRx for all specialty medications, including Naglazyme. A prescription is just the starting point—you need documented proof of MPS VI diagnosis, failed alternatives (if any exist), and medical necessity.

Myth 2: "I can get Naglazyme at any hospital or clinic"

Fact: UnitedHealthcare's Site of Care policy steers infusions to home, ambulatory centers, or physician offices unless you meet specific criteria for hospital outpatient treatment (medical instability, high-risk reactions, severe access issues). The drug must also be sourced through designated specialty pharmacies.

Myth 3: "Step therapy means I have to try cheaper alternatives first"

Fact: Since Naglazyme is the only FDA-approved enzyme replacement therapy for MPS VI, traditional step therapy doesn't apply. However, UnitedHealthcare still requires documentation that supportive care alone is insufficient and that enzyme replacement therapy is medically necessary.

Myth 4: "If I'm denied once, there's nothing I can do"

Fact: Virginia law provides robust appeal rights. You have 180 days for UnitedHealthcare internal appeals and 120 days for external review through the Virginia State Corporation Commission Bureau of Insurance. Many denials are overturned with proper documentation.

Myth 5: "My plan type doesn't matter for coverage"

Fact: UnitedHealthcare's specialty pharmacy sourcing rules and Site of Care policies vary significantly between Commercial, Medicare Advantage, and Medicaid plans. They also have state-specific variations—some requirements don't apply to UHC West, UMR, or certain Virginia regulations.

Myth 6: "Genetic testing isn't necessary if enzyme levels are low"

Fact: While enzyme assay showing arylsulfatase B deficiency confirms the diagnosis, UnitedHealthcare's enzyme replacement therapy policy typically requires both biochemical and genetic confirmation of MPS VI for coverage approval.

Myth 7: "Once approved, I don't need to worry about reauthorization"

Fact: Naglazyme requires periodic reauthorization (typically every 6-12 months) with evidence of ongoing benefit through functional tests like 12-minute walk tests, stair climbing assessments, and urine GAG levels compared to baseline.

What Actually Influences UnitedHealthcare Approval

Understanding UnitedHealthcare's actual decision-making criteria removes the guesswork from the approval process:

Core Documentation Requirements

Requirement What UnitedHealthcare Needs Where to Get It
Confirmed MPS VI Diagnosis Enzyme assay showing ASB deficiency + genetic testing Metabolic specialist, reference lab
Baseline Functional Status 12-minute walk test, 3-minute stair climb test Physical therapy or clinic
Specialist Involvement Letter from metabolic/genetic specialist MPS specialist or pediatric geneticist
Medical Necessity Documentation Clinical rationale, treatment goals, monitoring plan Prescribing physician
Correct Coding HCPCS J1458, ICD-10 E76.29 Billing department

Site of Care Approval Factors

UnitedHealthcare approves hospital outpatient infusion only when patients meet specific criteria:

  • Medical instability requiring hospital-level monitoring
  • High risk for severe infusion reactions needing emergency response
  • Severe vascular access issues requiring specialized equipment
  • IgA deficiency with anti-IgA antibodies (for IVIG patients)
  • Remote geography with no ambulatory alternatives

Specialty Pharmacy Requirements

For most UnitedHealthcare Commercial plans, Naglazyme must be:

  • Dispensed through designated specialty pharmacies (often Optum Specialty Pharmacy)
  • Shipped to the administration site
  • Billed separately from administration services

Avoid These 5 Preventable Mistakes

1. Submitting Incomplete Prior Authorization Packets

The Error: Sending PA requests without all required documentation The Fix: Use UnitedHealthcare's provider portal or CoverMyMeds to ensure all fields are complete. Include enzyme assay, genetic testing, baseline functional tests, and specialist letter in one submission.

2. Ignoring Site of Care Requirements

The Error: Scheduling hospital infusion without SOC justification The Fix: Document medical necessity for hospital setting or arrange home/ambulatory infusion with specialty pharmacy coordination.

3. Missing Reauthorization Deadlines

The Error: Waiting until coverage expires to request renewal The Fix: Set calendar reminders 30 days before authorization expires. Prepare updated functional assessments and response documentation.

4. Using Wrong Appeal Channels

The Error: Filing complaints with the wrong agency or missing deadlines The Fix: Follow UnitedHealthcare's internal process first, then Virginia's external review through the State Corporation Commission within required timeframes.

5. Inadequate Medical Necessity Letters

The Error: Generic letters that don't address UnitedHealthcare's specific criteria The Fix: Include confirmed diagnosis, baseline function, treatment goals, lack of alternatives, and monitoring plan. Reference UnitedHealthcare's enzyme replacement therapy policy directly.

Your 3-Step Action Plan for Today

Step 1: Verify Your Coverage Details (30 minutes)

Call the member services number on your UnitedHealthcare ID card and ask:

  • "Is Naglazyme (HCPCS J1458) covered under my medical benefit?"
  • "Do I need prior authorization through OptumRx?"
  • "What specialty pharmacy requirements apply to my plan?"
  • "Is my plan subject to Site of Care policies?"

Step 2: Gather Required Documentation (1-2 weeks)

Contact your healthcare team to ensure you have:

  • Enzyme assay results showing arylsulfatase B deficiency
  • Genetic testing confirming ARSB mutations
  • Baseline 12-minute walk test and 3-minute stair climb test
  • Current weight and proposed dosing schedule
  • Comprehensive medical necessity letter from your specialist

Step 3: Submit Prior Authorization (Same day when ready)

Use UnitedHealthcare's provider portal or CoverMyMeds to submit your complete PA packet. Record the confirmation number and set follow-up reminders for 7 and 14 days to check status.

From Our Advocates: We've seen families succeed by treating the PA process like a research project. One family created a simple spreadsheet tracking all required documents, submission dates, and follow-up calls. This organized approach helped them catch a missing lab report that would have delayed approval by weeks. While every case is different, systematic preparation consistently improves outcomes.

Frequently Asked Questions

How long does UnitedHealthcare prior authorization take for Naglazyme in Virginia? Standard review takes up to 15 business days when all documentation is complete. Expedited review (when provider certifies urgency) typically takes 72 hours.

What if Naglazyme isn't on my UnitedHealthcare formulary? Naglazyme is typically covered under the medical benefit (not pharmacy formulary) and billed with HCPCS code J1458. Check your medical benefits, not prescription drug coverage.

Can I request an expedited appeal in Virginia? Yes, if your provider certifies that delay could seriously jeopardize your health or significantly reduce treatment effectiveness. Both UnitedHealthcare internal appeals and Virginia external reviews offer expedited options.

Does step therapy apply if I've tried treatments in another state? Documentation of prior therapies from any location should be included in your medical necessity letter. Since Naglazyme is the only ERT for MPS VI, traditional step therapy typically doesn't apply.

What happens if UnitedHealthcare requires home infusion but I need hospital monitoring? Document specific medical reasons requiring hospital-level care per UnitedHealthcare's Site of Care policy criteria. Include specialist letter explaining why alternative sites are unsafe or inappropriate.
