Scripts for Peer-to-Peer Reviews

For the Prescribing Physician

When Cigna offers a peer-to-peer review, use this framework:

Opening Statement: "I'm calling regarding [Patient Name]'s prior authorization denial for Carbaglu. This patient has genetically confirmed NAGS deficiency with documented hyperammonemia requiring FDA-approved treatment."

Key Points to Cover:

  1. Diagnosis confirmation: "Genetic testing confirmed NAGS deficiency on [date] at [facility]"
  2. Clinical necessity: "Baseline ammonia was [level] micromol/L, indicating hyperammonemia"
  3. FDA indication: "Carbaglu is FDA-approved specifically for this condition"
  4. Treatment plan: "Patient is on protein-restricted diet with metabolic specialist oversight"
  5. Risk without treatment: "Untreated hyperammonemia poses significant neurological risks"

Closing: "I'm happy to provide additional documentation. What specific information would help expedite approval?"

FAQ

How long does Cigna prior authorization take for Carbaglu in New York?

Standard PA decisions are typically made within 5-15 business days. Expedited reviews (for urgent cases) are completed within 72 hours.

What if Carbaglu is non-formulary on my Cigna plan?

You can request a formulary exception by demonstrating medical necessity and that formulary alternatives are inappropriate or ineffective for your specific condition.

Can I request an expedited appeal in New York?

Yes, both Cigna internal appeals and New York external reviews offer expedited timelines (72 hours) when a physician certifies that waiting would seriously jeopardize your health.

Does step therapy apply to Carbaglu for NAGS deficiency?

Typically no, since Carbaglu is the FDA-approved first-line treatment for NAGS deficiency. However, some plans may require documentation that other ammonia-lowering treatments are inappropriate.

What happens if my external appeal is denied in New York?

New York's external review decision is binding on the insurer. If denied, you may need to explore alternative treatments, manufacturer assistance programs, or legal consultation.

How much does Carbaglu cost without insurance?

Cash prices can exceed $200 per 200mg tablet, with total monthly costs varying significantly based on weight-based dosing requirements.

Can my pediatrician submit the prior authorization?

While technically possible, Cigna requires the medication to be prescribed by or in consultation with a metabolic disease specialist, so specialist involvement is essential.

What documentation do I need for a successful appeal?

Key documents include genetic testing confirming NAGS deficiency, baseline and recent ammonia levels, metabolic specialist consultation notes, protein-restricted diet plan, and FDA approval documentation.
