Renewal Triggers

Your Carbaglu authorization doesn't automatically continue—Cigna requires periodic renewal to confirm ongoing medical necessity for NAGS deficiency treatment. Here's when to start preparing:

Signs You Should Start Early

  • Authorization expiration approaching: Check your myCigna portal or Accredo communications for your specific renewal date
  • Lab values changing: If recent plasma ammonia levels show variations, gather trending data
  • Dose adjustments: Any weight-based dosing changes require updated documentation
  • Provider transitions: New metabolic specialist requires credential verification with Cigna
Tip: Accredo proactively monitors renewal dates and sends reminders, but don't rely solely on this—set your own calendar alerts 30 days before expiration.

According to Cigna's specialty pharmacy guidance, most specialty drug authorizations require renewal every 6-12 months, with the specific timeline noted in your approval letter.

Evidence Update Requirements

Cigna's renewal criteria for Carbaglu focus on demonstrating continued therapeutic benefit through laboratory monitoring and clinical stability.

Required Laboratory Documentation

Plasma Ammonia Monitoring:

  • Recent ammonia levels (within 30-60 days of renewal request)
  • Trending data showing sustained control in normal range
  • Documentation of monitoring frequency (typically every 3 months for stable patients)

Supporting Labs:

  • Current weight for accurate dosing calculations
  • Liver function tests if clinically indicated
  • Nutritional status markers per specialist assessment

Clinical Response Documentation

Your metabolic specialist must document:

  • Therapeutic response: Reduction in hyperammonemic episodes
  • Functional improvement: Clinical stability and quality of life measures
  • Adherence confirmation: Patient compliance with prescribed regimen
  • Ongoing medical necessity: Why continued therapy remains essential

According to Cigna's carglumic acid policy, renewal requires "documented clinical benefit with normalization of plasma ammonia levels."

Building Your Renewal Packet

Must-Include Documents

Document Type Details Source
Provider Letter Medical necessity update from metabolic specialist Prescribing physician
Lab Results Recent plasma ammonia, weight, supporting labs Laboratory/clinic
Treatment Summary Response to therapy, adherence, clinical stability Medical records
Current Prescription Updated dosing if weight-based adjustments needed Prescriber

Letter of Medical Necessity Update Structure

Your specialist's renewal letter should address:

  1. Confirmed NAGS deficiency diagnosis (genetic/enzymatic testing results)
  2. Current clinical status and response to Carbaglu therapy
  3. Recent laboratory data demonstrating ammonia control
  4. Continued medical necessity for ongoing treatment
  5. Alternative therapy assessment (why other treatments remain inappropriate)
Clinician Corner: Include specific ammonia values with dates, reference ranges, and trending data. Cite the FDA prescribing information for dosing rationale and monitoring requirements.

When Coverage Lapses

If your authorization expires before renewal approval, you have several options:

Temporary Supply Options

Emergency Fill: Cigna may authorize a one-time 30-day supply while renewal is processed Accredo Bridge: Specialty pharmacy may provide temporary supply pending authorization Manufacturer Support: Contact Recordati Rare Diseases patient assistance programs

Escalation Steps

  1. Contact Accredo immediately to request emergency authorization
  2. Provider peer-to-peer review with Cigna medical director
  3. Expedited appeal if medical urgency exists
  4. External review through Washington's IRO process if internal appeals fail
Note: Never stop Carbaglu abruptly without medical supervision. Hyperammonemic crises can be life-threatening in NAGS deficiency.

Annual Formulary Changes

Washington insurers update formularies annually during open enrollment, potentially affecting your Carbaglu coverage.

What to Verify Each January

  • Formulary status: Confirm Carbaglu remains covered
  • Tier placement: Check if cost-sharing has changed
  • Prior authorization requirements: Verify if criteria have been modified
  • Quantity limits: Review any new restrictions on supply limits

Formulary Change Protections

If Cigna removes Carbaglu from formulary or increases restrictions:

  • 60-day advance notice required for affected members
  • Transition supply available while seeking alternatives
  • Formulary exception process to maintain current coverage
  • External review rights if exceptions are denied

According to Washington state insurance regulations, members have strong protections against mid-year formulary changes affecting ongoing specialty drug therapy.

FAQ

How long does Cigna take to process Carbaglu renewals in Washington? Typically 7-14 business days when complete documentation is provided through Accredo coordination. Expedited reviews available for urgent medical situations.

What if my ammonia levels are slightly elevated at renewal? Document the clinical context with your specialist. Trending data showing overall improvement and clinical stability are more important than single elevated values.

Can I request a longer authorization period? Most Cigna authorizations are limited to 12 months maximum. Some stable patients may receive shorter periods requiring more frequent renewal.

Does step therapy apply to Carbaglu renewals? For confirmed NAGS deficiency, step therapy typically doesn't apply as Carbaglu is the specific treatment for this rare condition. Document diagnosis clearly.

What if I change metabolic specialists during renewal? Ensure new provider is credentialed with Cigna and has access to complete medical records. May require additional documentation to establish continuity of care.

Are there manufacturer support programs for coverage gaps? Recordati Rare Diseases offers patient assistance programs. Contact their patient support services for eligibility and application information.
