Plan Types & Coverage Differences

HMO vs PPO vs EPO Requirements

HMO Plans require a referral from your primary care provider before seeing an endocrinologist or metabolic specialist. Without this referral, you may face reduced coverage or full payment responsibility.

PPO and EPO Plans don't require referrals to specialists, allowing you to schedule directly with metabolic disease specialists. However, prior authorization remains mandatory for Carbaglu regardless of plan type.

Note: New Jersey has no state mandate exempting metabolic disorders from referral requirements, so your specific Cigna plan type determines these rules.

Formulary Status & Tier Placement

Carbaglu is classified as a Tier 4 Specialty Drug on Cigna's 2025 formulary. This placement means:

  • Higher copayments or coinsurance compared to generic medications
  • Mandatory prior authorization before coverage
  • Dispensing through specialty pharmacy networks only
  • Potential quantity limits based on FDA-approved dosing

Appeals Process in New Jersey

Internal Appeals Timeline

Level 1 Appeal: 180 days from denial date to file, 30 days for Cigna review

Level 2 Appeal: 60 days to file after Level 1 denial, 30 days for review

Expedited Appeals: 72 hours for urgent medical situations

External Review Through IHCAP

After exhausting internal appeals, New Jersey members can request an Independent Health Care Appeals Program (IHCAP) review within 4 months of final internal denial. This process:

  • Costs nothing to members (insurers pay review fees)
  • Provides binding decisions that Cigna must follow
  • Has approximately 50% success rate favoring consumers
  • Involves independent medical experts reviewing your case

To file an IHCAP appeal, contact 1-888-393-1062 or submit directly to Maximus Federal Services, the contracted review organization.

From our advocates: We've seen cases where initial Carbaglu denials were overturned at external review when families provided comprehensive genetic testing results alongside detailed specialist letters explaining why alternative therapies wouldn't be appropriate. The key was demonstrating that the denial contradicted established medical guidelines for NAGS deficiency management.

FAQ

How long does Cigna prior authorization take for Carbaglu in New Jersey? Standard reviews take up to 30 days, while urgent cases receive decisions within 72 hours. New Jersey law requires responses to prior authorization requests within 9 calendar days starting in 2025.

What if Carbaglu is denied as "not medically necessary"? Request a peer-to-peer review where your specialist can discuss the case directly with Cigna's medical director. Provide additional clinical literature supporting the diagnosis and treatment plan.

Can I get temporary coverage while appeals are pending? For urgent medical needs, request expedited review and ask your doctor about manufacturer patient assistance programs or emergency supplies while waiting for approval.

Does step therapy apply to Carbaglu for NAGS deficiency? No, Cigna's policy doesn't require trying alternative medications first for confirmed NAGS deficiency, as Carbaglu is the specific treatment for this condition.

What counts as a metabolic disease specialist for Cigna's requirements? Typically endocrinologists with metabolic specialization, geneticists, or physicians at metabolic treatment centers. Verify with Cigna that your specific provider meets their criteria.

How do I know if my genetic testing is sufficient for approval? The testing must specifically confirm NAGS deficiency through enzymatic assay, biochemical analysis, or genetic sequencing. General metabolic panels may not be sufficient.
