Read Your Denial Letter

When Aetna CVS Health denies Ferriprox coverage, your denial letter contains critical information that determines your next steps. Look for these key details:

Denial reason codes typically include:

  • Prior authorization required
  • Not medically necessary
  • Experimental/investigational
  • Step therapy required (try Exjade or Desferal first)
  • Non-formulary medication

Appeal deadlines: You have 60 days from the denial date to file an internal appeal with Aetna. Mark this date immediately on your calendar.

Benefit type: Ferriprox may be covered under medical benefit (if administered in clinic) or pharmacy benefit (for home use). This affects which department handles your appeal.

Tip: If your denial letter mentions "CVS Caremark," your case is handled through the pharmacy benefit. If it references "Aetna medical management," it's under the medical benefit.

California Step Therapy Override Rights

California law provides strong protections against inappropriate step therapy requirements. Under AB 347 (2021), you can request exceptions when:

Automatic Override Conditions

  • Medical contraindication to required first-line drug
  • Previous trial and failure of step therapy drug
  • Documented intolerance or adverse reaction
  • Drug interaction with current medications

Timeline Requirements

  • Health plans must respond within 72 hours (24 hours urgent)
  • Automatic approval if plan fails to respond on time
  • Exception covers entire prescription duration including refills

Documentation Needed

  • Clinical notes detailing contraindication or prior failure
  • Laboratory evidence (e.g., ANC drop with previous chelator)
  • Physician attestation of medical necessity
Note: For iron chelation therapy, common step therapy requires trying Exjade (deferasirox) before Ferriprox. Document any GI intolerance, renal concerns, or drug interactions to support override requests.

When Appeals Fail: California IMR Process

California's Independent Medical Review offers a final pathway when Aetna denies coverage after internal appeals. The process is robust and patient-friendly:

Filing Requirements

  1. Complete internal appeal process first
  2. Submit IMR application within 6 months of final denial
  3. Include all medical records and physician statements
  4. No filing fee required

Timeline & Process

  • Standard IMR: 45 days maximum
  • Expedited IMR: 7 days (often 72 hours)
  • Independent physician reviewers evaluate medical necessity
  • Decision is binding on Aetna

How to Apply

  • Online: DMHC IMR portal
  • Phone: 888-466-2219

Frequently Asked Questions

How long does Aetna prior authorization take for Ferriprox in California? Standard PA decisions take up to 15 business days. Expedited requests for urgent medical situations are decided within 72 hours.

What if Ferriprox isn't on Aetna's formulary? Request a formulary exception by demonstrating medical necessity and providing clinical documentation. Non-formulary drugs can still be covered with proper justification.

Can I request an expedited appeal if I'm already on Ferriprox? Yes, if interrupting therapy could cause serious health consequences. Your physician must document the urgency and potential harm from treatment delay.

Does step therapy apply if I failed chelation therapy outside California? Previous treatment failures from any location count toward step therapy requirements. Ensure your new California physician documents the prior treatment history.

What happens if both Aetna appeal and California IMR deny coverage? Consider requesting a second opinion, exploring clinical trials, or working with patient advocacy organizations. Some patients successfully appeal again with additional clinical evidence.

How much does Ferriprox cost without insurance in California? Cash prices range from approximately $7,500-$8,000 monthly depending on dose and pharmacy. Manufacturer patient assistance programs can significantly reduce these costs.
