Renewal Triggers: When to Start Early

Standard Renewal Timeline

Aetna CVS Health typically approves Cystadane for 12-month periods, requiring renewal documentation before expiration. Start your renewal process 60-90 days early if you notice these triggers:

  • Current authorization expires within 3 months
  • Homocysteine levels have changed significantly
  • Dosing adjustments were made during the current approval period
  • You've switched from another insurer to Aetna CVS Health

Red Flag Situations Requiring Immediate Action

Contact your prescriber immediately if:

  • You receive a "discontinuation notice" from CVS Specialty Pharmacy
  • Your pharmacy indicates "prior authorization expired"
  • Aetna requests additional documentation mid-approval period
Tip: Set a calendar reminder 90 days before your current PA expires. Renewals submitted early rarely face processing delays.

Evidence Update Requirements

Core Lab Values (Required Within 6 Months)

Your renewal must include current laboratory evidence demonstrating ongoing medical necessity:

Primary Markers:

  • Total plasma homocysteine levels - the key efficacy indicator showing treatment response
  • Plasma methionine levels - should show appropriate increases as homocysteine converts to methionine
  • Methylmalonic acid (if relevant to your specific genetic defect)

Treatment Effectiveness Benchmarks:

Genetic Confirmation (From Initial Approval)

Your renewal should reference the original genetic testing that confirmed one of these homocystinuria types:

  • CBS deficiency (cystathionine beta-synthase)
  • MTHFR deficiency (beyond common variants like C677T)
  • Cobalamin metabolism defects (cblC, cblD, cblE, cblF, cblG, cblJ)
