How to Use This Decision Tree

This guide helps you determine if you qualify for Cystadane coverage through Aetna CVS Health and shows you the fastest path to approval in Ohio. Work through each section in order—the eligibility triage will direct you to the right next steps based on your specific situation.

What you'll need before starting:

  • Insurance card and member ID
  • Recent lab results (homocysteine, methionine levels)
  • Genetic test results (if available)
  • List of previous treatments tried
  • Contact information for your prescribing doctor

Eligibility Triage: Do You Qualify?

Likely Eligible ✅

You probably qualify for Cystadane coverage if you have:

  • Confirmed homocystinuria diagnosis with genetic testing showing pathogenic variants in CBS, MTHFR, or cobalamin metabolism genes
  • Elevated homocysteine levels (>50 µmol/L in neonates, >100 µmol/L in older patients)
  • Failed or cannot tolerate vitamin B6, B12, folate, or dietary restrictions
  • Specialist involvement (geneticist or metabolic specialist)

Next step: Go to the Document Checklist section.

Possibly Eligible ⚠️

You might qualify but need additional testing if you have:

  • Clinical symptoms of homocystinuria but incomplete genetic testing
  • Elevated homocysteine but unclear cause
  • Family history of homocystinuria but no personal testing
  • Some vitamin therapy trials but incomplete documentation

Next step: See Tests to Request section.

Not Yet ❌

You'll need more preparation if you have:

  • No genetic confirmation of homocystinuria
  • Haven't tried standard vitamin therapies
  • No specialist involvement or referral
  • Normal homocysteine levels without clear clinical indication

Next step: Review Alternative Options section.

If "Likely Eligible": Document Checklist

Required Documentation

Medical Records:

  • Genetic test report showing pathogenic CBS, MTHFR, or cobalamin variants
  • Lab results with elevated homocysteine (>50-100 µmol/L depending on age)
  • Elevated methionine levels (if CBS deficiency)
  • Specialist consultation notes (genetics/metabolism)

Treatment History:

  • Documentation of vitamin B6 trial and outcome
  • Documentation of vitamin B12 trial and outcome
  • Documentation of folate trial and outcome
  • Records of dietary restriction attempts (if applicable)
  • Any adverse reactions or contraindications to standard therapies

Prescription Details:

  • Prescription from qualified specialist
  • Dosing rationale based on weight/severity
  • Treatment goals and monitoring plan

Submission Path

  1. Provider submits via Aetna portal - Your doctor should use the Aetna precertification system at least 2 weeks before you need the medication.
  2. Include all documentation - Incomplete submissions cause delays. Aetna processes most complete requests within 24 hours.
  3. Track your request - Your doctor can check status through the provider portal or by calling Aetna's provider services line.

If "Possibly Eligible": Tests to Request

Genetic Testing Priority

First-line testing:

  • CBS gene sequencing - Gold standard for classic homocystinuria diagnosis
  • Plasma total homocysteine - Must be markedly elevated for insurance coverage
  • Plasma amino acids - Shows elevated methionine in CBS deficiency

Second-line if CBS negative:

  • MTHFR gene testing - Only covered if CBS testing is negative and clinical suspicion remains high
  • Vitamin B6 responsiveness testing - Helps determine treatment approach

Not typically covered:

  • Routine MTHFR testing for mild hyperhomocysteinemia
  • Cobalamin metabolism genes (MTR, MTRR, MMADHC) unless specific clinical indication

Timeline to Reapply

  • Genetic test results: 2-4 weeks
  • Specialist consultation: 1-3 weeks (may have longer wait times)
  • Prior authorization after testing: 24-72 hours with complete documentation

Request genetic testing through a metabolic specialist who can also provide the required medical necessity documentation for your eventual Cystadane prior authorization.

If "Not Yet": Alternative Options

Standard Therapy Requirements

Before Cystadane approval, insurers typically require documented trials of:

Vitamin Therapies:

  • Pyridoxine (Vitamin B6) - 100-500mg daily for 6-8 weeks
  • Cyanocobalamin (Vitamin B12) - high-dose supplementation
  • Folic acid - 5-10mg daily
  • Combination vitamin therapy

Dietary Management:

  • Methionine-restricted diet (for CBS deficiency)
  • Protein restriction as appropriate
  • Nutritionist consultation documentation

Preparing for Exception Requests

If standard therapies aren't appropriate due to:

  • Contraindications - Document medical reasons vitamins can't be used
  • Severe symptoms - Show urgent need for immediate Cystadane therapy
  • Previous failures - Include records from other providers/states

Work with a metabolic specialist to build a case for skipping step therapy requirements.

If Denied: Ohio Appeal Path

Internal Appeals with Aetna

FAQ

How long does Aetna CVS Health prior authorization take in Ohio? Most complete requests are processed within 24 hours. Incomplete documentation can cause delays of several days to weeks.

What if Cystadane is non-formulary on my plan? You can request a formulary exception with medical necessity documentation. Aetna must respond within 72 hours for standard requests.

Can I request an expedited appeal in Ohio? Yes, if delays would seriously jeopardize your health. Both Aetna internal appeals and Ohio external reviews offer expedited timelines (24-72 hours).

Does step therapy apply if I failed vitamins in another state? Yes, documented treatment failures from other providers/states should satisfy step therapy requirements. Include complete medical records.

What's the difference between CVS Caremark and CVS Specialty? CVS Caremark handles most prescriptions, while CVS Specialty manages specialty medications like Cystadane. Your prior authorization goes through the appropriate division automatically.

How much will Cystadane cost with Aetna coverage? Costs depend on your specific plan's specialty drug tier. Typical copays range from $50-500+ per month. Check your plan documents or call member services.

What if my doctor won't prescribe Cystadane? Seek consultation with a metabolic genetics specialist. Many primary care providers aren't familiar with rare disease treatments and may need specialist guidance.

Can I appeal directly to Ohio without going through Aetna first? No, you must complete Aetna's internal appeal process before requesting external review through Ohio Department of Insurance.

From our advocates: We've seen patients successfully overturn Cystadane denials by ensuring their genetic test results clearly show pathogenic variants and their medical necessity letters specifically address each denial reason mentioned in Aetna's policy. The key is matching your documentation exactly to the insurer's published criteria rather than providing generic medical information.

When Coverage Gets Complex

For patients dealing with repeated denials or complex insurance situations, specialized advocacy can make the difference.
