What This Guide Covers

This guide helps Virginia residents navigate Cigna's prior authorization process for Carbaglu (carglumic acid), a life-saving medication for rare metabolic disorders. Whether you're a patient with NAGS deficiency, a caregiver, or a healthcare provider, you'll find step-by-step instructions, required forms, and Virginia-specific appeal rights.

Carbaglu is FDA-approved for treating hyperammonemia in patients with N-acetylglutamate synthase (NAGS) deficiency and certain organic acidemias. With monthly costs exceeding $40,000, proper insurance coverage is essential for accessing this orphan drug.

Before You Start: Verify Your Coverage

Confirm Your Plan Type

First, determine if you have a Cigna commercial plan, Medicare Advantage, or employer-sponsored coverage. Each has different PA requirements and appeal processes. Check your insurance card for:

  • Member ID and group number
  • Whether it's an HMO, PPO, or EPO plan
  • Pharmacy benefit manager (likely Express Scripts/Accredo)

Verify Network Status

Ensure your prescribing physician is in-network with Cigna. Metabolic specialists and pediatric endocrinologists are typically required for Carbaglu prescriptions under Cigna's coverage policy.

Check Formulary Status

Carbaglu requires prior authorization across all Cigna plans. It's not listed on standard formularies but is covered for FDA-approved indications when medical necessity criteria are met.

Gather Required Documentation

Essential Clinical Evidence

Diagnostic Confirmation (Required)

  • Genetic testing results confirming NAGS deficiency
  • Biochemical analysis showing enzyme deficiency
  • Elevated plasma ammonia levels above normal range
  • ICD-10 code E72.2 (Disorders of urea cycle metabolism)

Specialist Documentation

  • Prescription from metabolic disease specialist
  • Consultation notes detailing diagnosis and treatment plan
  • Documentation of protein-restricted diet management
  • Treatment goals and monitoring plan

Laboratory Results

  • Baseline ammonia levels
  • Plasma glutamine levels
  • Citrulline concentrations
  • Complete metabolic panel

Supporting Materials

Include FDA prescribing information, relevant clinical studies, and any prior therapy documentation. For patients with organic acidemias, document acute hyperammonemia episodes and concurrent treatments.

Submit the Prior Authorization Request

Cigna Provider Portal Submission

Healthcare providers should submit PA requests through the Cigna provider portal or via Express Scripts if using specialty pharmacy services. The submission must include:

  1. Completed PA form with all required fields
  2. Clinical documentation supporting medical necessity
  3. Specialist consultation notes
  4. Laboratory results and diagnostic tests
  5. Treatment history and prior therapy failures (if applicable)

Specialty Pharmacy Coordination

Carbaglu is typically dispensed through Cigna's specialty pharmacy network (Express Scripts/Accredo). Coordinate with the specialty pharmacy to ensure they receive the approved PA before attempting to fill the prescription.

Tip: Submit requests early in the week to avoid weekend delays. Include a cover letter summarizing the medical necessity and referencing Cigna's own coverage criteria.

Follow-Up and Tracking

When to Call

Contact Cigna within 3-5 business days of submission to confirm receipt and obtain a reference number. For urgent cases, call daily to check status.

Sample Call Script

"I'm calling to check on a prior authorization request for Carbaglu submitted on [date] for patient [name], member ID [number]. This is for a rare metabolic disorder requiring urgent approval. Can you provide the status and reference number?"

Documentation

Keep detailed records of all communications, including dates, representative names, and reference numbers. This documentation becomes crucial if appeals are needed.

Understanding Cigna's Timeline

Standard Processing

  • Initial review: 5 business days for standard requests
  • Medical review: Additional 3-5 days if clinical evaluation needed
  • Total timeline: Typically 7-14 business days

Expedited Reviews

For urgent medical situations, request expedited review:

  • Cigna timeline: 24-72 hours for urgent requests
  • Qualification: Life-threatening hyperammonemia or acute metabolic crisis
  • Documentation: Physician attestation of urgency required

If More Information is Requested

Cigna may request additional documentation during review. Common requests include:

  • Genetic testing confirmation: Complete sequencing results
  • Specialist consultation: Detailed metabolic evaluation
  • Diet documentation: Protein restriction plan from dietitian
  • Treatment response: Evidence of ammonia level improvement

Respond promptly to these requests, as delays can result in automatic denials.

If Your Request is Denied

Common Denial Reasons

Denial Reason How to Address
Insufficient genetic confirmation Submit complete NAGS gene sequencing results
Missing specialist consultation Obtain evaluation from metabolic disease specialist
Incomplete laboratory data Provide baseline and follow-up ammonia levels
Off-label use Clarify FDA-approved indication with supporting documentation

Internal Appeal Process

File your internal appeal within 180 days of the denial notice. Include:

  1. Appeal letter addressing specific denial reasons
  2. Additional clinical evidence requested by medical reviewers
  3. Peer-reviewed literature supporting treatment necessity
  4. Specialist letter detailing medical necessity

Peer-to-Peer Review

Request a peer-to-peer consultation where your physician speaks directly with Cigna's medical director. This often resolves denials when clinical complexity isn't captured in written documentation.

Virginia External Review Process

If Cigna upholds the denial after internal appeals, Virginia residents have strong external review rights through the State Corporation Commission's Bureau of Insurance.

Submit Form 216-A (Request for External Review) within 120 days of your final denial notice. The form is available from the Virginia SCC Bureau of Insurance.

Timeline and Process

  • Expedited review: 72 hours for urgent cases
  • Cost: Free to Virginia residents
  • Decision: Binding on Cigna if overturned

From Our Advocates

We've seen many Carbaglu approvals succeed when families work closely with their metabolic specialist to document the complete clinical picture. One key insight: Cigna's medical reviewers respond well when the specialist's letter explicitly references the insurer's own coverage criteria and explains why this specific patient meets each requirement. Don't assume the reviewer understands rare metabolic disorders—spell out why Carbaglu is the only effective treatment option.
