Plan Types & Coverage Implications

Your Aetna plan type affects referral requirements and network rules, but all Aetna plans require prior authorization for Lamzede.

Plan Type Referral Needed? Network Requirements Average Premium (Silver)
HMO Yes, from PCP In-network only $617/month
PPO No In/out-network (higher cost out) $880/month
EPO No In-network only $464/month
Important: Aetna is leaving North Carolina's ACA Marketplace in 2026, so if you have a Marketplace plan, you'll need to select a new insurer during open enrollment.

For HMO members, ensure your PCP provides a referral to an enzyme/metabolic specialist before starting the PA process. EPO and PPO members can work directly with specialists.

Formulary Status & Tier Placement

Lamzede (velmanase alfa) is covered on Aetna's formulary but requires precertification. The drug is billed under:

  • 2024: J3490, J3590, C9399 (transitional codes)
  • 2025: J0217 (new permanent code)

Lamzede is classified as a specialty medication, meaning it's typically subject to higher cost-sharing and must be obtained through designated specialty pharmacies.

Prior Authorization Requirements

Aetna's clinical policy requires specific documentation for Lamzede approval:

Initial Approval Criteria

✅ Prescriber: Must be a physician specializing in enzyme or metabolic disorders
✅ Diagnosis: Non-CNS manifestations of alpha-mannosidosis confirmed by:

  • Documented alpha-mannosidase enzyme deficiency in blood leukocytes or fibroblasts, OR
  • Genetic testing showing pathogenic MAN2B1 gene variant(s)

✅ Clinical Documentation: Medical records supporting the diagnosis

Reauthorization Requirements

For continued coverage, you must provide evidence of clinical benefit such as:

  • Improvement in 3-minute stair climb test (3MSCT)
  • Better performance on 6-minute walk test (6MWT)
  • Increased forced vital capacity (FVC)
  • Reduced serum/urine oligosaccharide levels

Specialty Pharmacy Setup

Lamzede must be obtained through CVS Specialty Pharmacy or another Aetna-approved specialty pharmacy. Here's the setup process:

  1. Prescriber submits PA: Include all clinical documentation
  2. PA approval: Usually within 24-48 hours for complete submissions
  3. Specialty pharmacy enrollment: CVS Specialty contacts patient to set up delivery
  4. Infusion coordination: Work with your treatment center for weekly IV infusions
Tip: Use electronic prior authorization (ePA) when possible—it's 2-3 times faster than manual submissions.

Lamzede costs approximately $1.46 million annually for a 70kg patient. Your out-of-pocket costs depend on your plan's:

  • Annual deductible
  • Specialty drug coinsurance (typically 20-40%)
  • Out-of-pocket maximum

Cost assistance options:

  • Manufacturer copay programs (check eligibility requirements)
  • Patient assistance foundations
  • State pharmaceutical assistance programs

Success Rates

To maximize success:

  • Submit comprehensive medical records
  • Include peer-reviewed literature supporting Lamzede use
  • Have your specialist write a detailed letter of medical necessity
From our advocates: In complex rare disease cases, we've seen external reviews succeed when providers submitted detailed functional assessments showing disease progression without treatment, combined with FDA labeling and clinical guidelines. The key is painting a complete clinical picture for the independent reviewer.

FAQ

How long does Aetna PA take for Lamzede in North Carolina?
Most decisions come within 24-48 hours for electronic submissions with complete documentation. Manual submissions may take up to 5-7 business days.

What if Lamzede is non-formulary on my plan?
Request a formulary exception by demonstrating medical necessity and that formulary alternatives are inappropriate for alpha-mannosidosis.

Can I request an expedited appeal?
Yes, if delay would seriously jeopardize your health. Aetna must decide urgent appeals within 72 hours.

Does step therapy apply to Lamzede?
Typically no, since Lamzede is the first FDA-approved treatment for alpha-mannosidosis. However, some plans may require documentation that supportive care alone is insufficient.

What happens if Smart NC external review is denied?
The external review decision is binding on Aetna. Further options may include legal consultation or seeking coverage through alternative programs.

Can I use manufacturer copay assistance with Aetna?
Check your plan's copay accumulator policy. Some plans don't count manufacturer assistance toward your deductible or out-of-pocket maximum.
