How to Use This Decision Tree

This guide helps you navigate Cigna's prior authorization process for Cystadane (betaine anhydrous) in North Carolina. Work through each section based on your current situation—whether you're preparing your first request, facing a denial, or exploring alternatives.

Before you start, gather:

  • Insurance card and policy details
  • Complete diagnosis and lab results
  • List of previous treatments tried
  • Current prescriber information
  • Any denial letters or EOBs

Eligibility Triage: Do You Qualify?

Likely Eligible ✅

You probably qualify if you have:

  • Confirmed homocystinuria diagnosis with plasma total homocysteine >50 µmol/L (neonates) or >100 µmol/L (older patients)
  • Genetic confirmation via CBS, MTHFR, or cobalamin-related gene testing
  • Elevated methionine (200-1500 µmol/L in neonates; >50 µmol/L older patients) for CBS deficiency
  • Prescriber specialty: Metabolic geneticist or physician experienced in inborn errors of metabolism
  • Documentation of vitamin co-therapy (B6, B12, folate) as appropriate

Possibly Eligible ⚠️

You may qualify with additional documentation if you have:

  • Biochemical evidence but pending genetic confirmation
  • Family history of homocystinuria with consistent symptoms
  • Elevated homocysteine but incomplete workup
  • Previous treatment response to betaine or methionine restriction

Not Yet ❌

You'll need more preparation if:

  • Diagnosis is unclear or homocysteine levels are borderline
  • No specialist involvement yet
  • Vitamin deficiencies haven't been ruled out
  • Alternative treatments haven't been tried or documented

  • Urine homocysteine if available

Clinical Information:

  • Complete medical history and physical exam
  • Documentation of symptoms (thromboembolism, lens dislocation, developmental concerns)

If "Possibly Eligible": Tests to Request

Additional Testing Needed

Laboratory Studies:

  • Comprehensive metabolic panel
  • Vitamin B6, B12, and folate levels
  • Methylmalonic acid (to rule out B12 deficiency)
  • Complete plasma amino acid analysis

Genetic Testing:

  • CBS gene sequencing if not done
  • MTHFR variant analysis
  • Cobalamin pathway gene panel if indicated

Specialist Consultation:

  • Referral to metabolic geneticist
  • Ophthalmologic exam for lens dislocation
  • Cardiology evaluation if thromboembolism history

Timeline to Re-apply

  • Genetic testing results: 2-4 weeks typically
  • Specialist appointments: May require 4-8 weeks wait
  • Lab turnaround: 1-2 weeks for most studies

Track all results and resubmit PA request once documentation is complete.

If "Not Yet": Alternatives to Discuss

Immediate Options

Vitamin Therapy:

  • Vitamin B12 supplementation
  • Folate therapy
  • Combination approach with dietary modification

FAQ

How long does Cigna prior authorization take for Cystadane in North Carolina? Standard reviews complete within 1-3 business days. Expedited reviews for urgent cases process within 24-72 hours.

What if Cystadane is non-formulary on my Cigna plan? Request a formulary exception by having your prescriber certify that formulary alternatives are ineffective or contraindicated.

Can I request an expedited appeal if my PA is denied? Yes, if delay would jeopardize your health or cause severe symptoms. Your prescriber must certify the urgency in writing.

Does step therapy apply to rare disease medications like Cystadane? Cigna may require documentation that standard treatments (vitamins, diet) were tried first, but exceptions are available for medical contraindications.

What genetic testing does Cigna typically require? CBS gene sequencing for classic homocystinuria, MTHFR testing for suspected deficiency, or cobalamin pathway genes for B12-related forms.

How much does Cystadane cost without insurance? Typical cash price ranges $150-300 per 180g bottle, but manufacturer assistance programs may be available.

Who can prescribe Cystadane for the best approval chances? Metabolic geneticists or physicians experienced in inborn errors of metabolism have the highest approval rates with Cigna.

What happens if Smart NC external review denies my appeal? The external review decision is final for administrative appeals, though legal options may still be available.
