How to Use This Guide

This decision tree helps you determine whether you qualify for Cystadane (betaine anhydrous) coverage through Humana in Texas and provides your next steps based on your situation.

Start here: Answer the questions in the eligibility triage below. Each outcome leads to specific actions you can take today to move toward coverage approval.

Note: Cystadane requires prior authorization from Humana and typically costs $150-$300 per 180g bottle without insurance coverage.

Eligibility Triage: Do You Qualify?

Question 1: Do you have a confirmed diagnosis of homocystinuria?

Required documentation:

  • Genetic testing showing CBS, MTHFR, or cobalamin metabolism defects
  • Elevated plasma homocysteine (>50 µmol/L in newborns, >100 µmol/L in older individuals)
  • Elevated plasma methionine levels

✅ Yes → Continue to Question 2
❓ Unsure → Go to "Possibly Eligible"
❌ No → Go to "Not Yet"

Question 2: Have you tried vitamin B6, B12, and folate therapy?

Humana requires documentation of vitamin cofactor trials before approving Cystadane, as these are first-line treatments for many forms of homocystinuria.

✅ Yes, with inadequate response → Go to "Likely Eligible"
❓ Partial response or unclear → Go to "Possibly Eligible"
❌ No trial yet → Go to "Not Yet"

Question 3: Is your homocysteine still elevated despite vitamin therapy?

✅ Yes (>15 µmol/L despite treatment) → Go to "Likely Eligible"
❌ No or normalized → Coverage may be denied; discuss with your specialist

If "Likely Eligible" - Your Action Plan

You have the strongest case for Cystadane approval. Here's your step-by-step path:

Document Checklist

Gather these items before your doctor submits the prior authorization:

  • Genetic testing results (CBS, MTHFR, or cobalamin defect confirmation)
  • Recent plasma homocysteine levels (within 3 months)
  • Recent plasma methionine levels
  • Documentation of vitamin B6, B12, folate trials with doses and duration
  • Current homocysteine levels despite vitamin therapy
  • ICD-10 diagnosis code (E72.11 for homocystinuria)
  • Prescriber's medical necessity letter

Submission Process

  1. Your doctor submits PA request via Humana's provider portal or fax to 1-877-486-2621
  2. Standard processing time: 7 calendar days for Part D medications
  3. Expedited option: 72 hours if delay would jeopardize your health
  4. Follow up: Track status through Humana member portal
Clinician Corner: Your medical necessity letter should include: confirmed genetic diagnosis, specific enzyme defect, current homocysteine levels, previous vitamin therapy attempts with specific doses and durations, rationale for betaine therapy per FDA prescribing information, and proposed dosing plan.

If "Possibly Eligible" - Tests to Request

You may qualify but need additional documentation. Request these tests from your healthcare provider:

Missing Diagnostic Tests

  • Genetic panel: CBS gene sequencing (first-line), MTHFR if CBS negative
  • Biochemical confirmation: Plasma total homocysteine, methionine levels
  • Vitamin status: B12, folate, B6 levels to rule out deficiency

Timeline to Re-apply

  • Allow 2-4 weeks for genetic testing results
  • Recheck homocysteine 4-6 weeks after starting vitamin therapy
  • Submit PA request once you have complete documentation

When working with insurance appeals, having comprehensive clinical documentation is crucial. Counterforce Health specializes in turning insurance denials into targeted, evidence-backed appeals by analyzing denial letters and payer policies to craft point-by-point rebuttals with the right medical evidence and procedural requirements.

If "Not Yet" - Alternative Approaches

If you don't yet meet criteria, consider these options:

First-Line Treatments

  • High-dose vitamin B6 (pyridoxine): 100-500mg daily for B6-responsive forms
  • Vitamin B12 and folate supplementation: Address any deficiencies first
  • Low-methionine diet: Work with metabolic dietitian

Coverage Alternatives

  • Generic betaine anhydrous: May be less expensive than branded Cystadane
  • Compounded trimethylglycine (TMG): Chemically identical, potentially covered
  • Patient assistance programs: Contact Recordati Rare Diseases for support options

Prepare for Exception Request

If standard therapy fails, gather documentation for a formulary exception:

  • Treatment failure records with specific vitamin doses and durations
  • Progressive homocysteine levels despite optimal vitamin therapy
  • Specialist letter supporting medical necessity

If Denied - Your Appeal Options

Humana denials can be appealed through multiple levels in Texas:

Level 1: Internal Appeal (Redetermination)

  • Deadline: 65 days from denial notice
  • Humana's decision timeframe: 7 days (standard) or 72 hours (expedited)
  • Submit via: Humana member exceptions and appeals page
  • Required: Completed redetermination form, supporting clinical documentation

Level 2: Independent Review Entity (IRE)

  • Deadline: 60 days from Level 1 denial
  • Decision timeframe: 7 days (standard) or 72 hours (expedited)
  • Automatic: Humana forwards your case if they uphold the denial

Texas External Review (if applicable)

For certain plan types, Texas offers independent external review through the Texas Department of Insurance:

Tip: Request peer-to-peer review between your prescriber and Humana's medical director before formal appeals. This informal discussion often resolves coverage issues faster.
