Cigna's Coverage Policy for Elaprase

Cigna considers Elaprase (idursulfase) medically necessary for Hunter syndrome (Mucopolysaccharidosis II) when specific clinical criteria are met. The policy applies to all Cigna commercial plans, including HMO, PPO, and POS products in North Carolina.

Key Policy Points

  • FDA-approved indication: Enzyme replacement therapy for Hunter syndrome in pediatric and adult patients
  • Formulary status: Typically requires prior authorization on specialty tier
  • Administration: IV infusion only, managed through specialty pharmacy network
  • Renewal requirements: Clinical improvement documentation every 12 months
Note: Cigna's specialty drug policies are updated regularly. Always verify current criteria through your provider portal or by calling Cigna directly at the number on your insurance card.

Required Diagnostic Testing

Before Cigna will approve Elaprase, you must have definitive confirmation of Hunter syndrome through both enzymatic and genetic testing.

Essential Lab Requirements

Enzymatic Testing

  • Iduronate-2-sulfatase (I2S) enzyme activity measurement
  • Must show reduced or absent enzyme activity
  • Acceptable specimens: blood, dried blood spot, or leukocytes

Genetic Confirmation

  • Full IDS gene sequencing
  • Deletion/duplication analysis if needed
  • Must identify pathogenic or likely pathogenic variants

Supporting Tests (helpful but not required)

  • Urine glycosaminoglycans (GAGs) - elevated levels support diagnosis
  • Clinical imaging showing characteristic organ involvement
Tip: If you only have enzymatic testing, genetic confirmation is still required for insurance approval. Contact a genetics laboratory or your metabolic specialist to arrange IDS gene testing.

Frequently Asked Questions

How long does Cigna prior authorization take for Elaprase in North Carolina? Standard PA review takes 72 hours. Expedited requests are reviewed within 24 hours if urgent medical need is documented.

What if Elaprase is non-formulary on my Cigna plan? Submit a formulary exception request with your prescriber. Document why formulary alternatives are inappropriate for Hunter syndrome (there are no FDA-approved alternatives for MPS II).

Can I request an expedited appeal if my child needs Elaprase urgently? Yes. Both Cigna internal appeals and Smart NC external review offer expedited pathways for urgent medical situations where delay could harm the patient.

Does step therapy apply to Elaprase for Hunter syndrome? Generally no, since Elaprase is the only FDA-approved enzyme replacement therapy for MPS II. However, Cigna may require documentation of supportive care measures tried first.

What happens if I move from another state where I was already on Elaprase? Document your current treatment response and clinical stability. Continuing therapy typically has lower barriers than initiating treatment, but you'll still need PA approval in North Carolina.

How often do I need to renew prior authorization for Elaprase? Most Cigna plans require annual reauthorization with documentation of clinical response, including objective measures like organ size reduction or improved functional capacity.
