California's Independent Medical Review (IMR)

California offers one of the strongest patient protection systems in the country through its Independent Medical Review process. When Humana denies coverage for Dupixent, California residents have the right to an independent, binding review.

Why IMR is Powerful for Dupixent Cases:

  • Independent physicians specializing in your condition review the case
  • Reviewers evaluate medical necessity based on current standards of care
  • High success rate for specialty medications with strong clinical evidence
  • Humana must comply with IMR decisions

IMR Success Factors:

  • Complete medical records including all prior treatments
  • Current clinical guidelines supporting Dupixent use
  • Specialist recommendations and severity documentation
  • Evidence of functional impairment or quality of life impact

Scripts for Success

"Hello, I'm calling about prior authorization for Dupixent for [condition]. My member ID is [X]. Can you tell me the specific requirements for approval and whether step therapy applies to my plan? I'd also like to know the exact fax number for submissions and typical processing time."

FAQ

How long does Humana prior authorization take in California? Standard decisions within 72 hours, expedited within 24 hours for urgent cases. California law requires timely processing of authorization requests.

What if Dupixent is non-formulary on my Humana plan? You can request a formulary exception with medical necessity documentation. Your prescriber must demonstrate that all formulary alternatives are ineffective or contraindicated.

Can I request expedited review? Yes, if delay would seriously jeopardize your health. Mark requests as "urgent" and provide clinical justification for expedited processing.

Does step therapy apply if I failed treatments in another state? Yes, document all prior treatments regardless of where they occurred. Include pharmacy records, physician notes, and treatment outcomes from previous states.

What happens if my IMR is denied? IMR decisions are generally final and binding. You may only appeal based on clear evidence of procedural error, conflict of interest, or fraud within 30 days.

How much does Dupixent cost without insurance? List price is approximately $3,993 per carton (two injections), but manufacturer copay programs and patient assistance can significantly reduce costs.

From Our Advocates: We've seen Dupixent appeals succeed when patients include comprehensive photo documentation of their condition's severity alongside detailed treatment histories. One case involved a patient whose atopic dermatitis significantly improved after documenting failed responses to six different topical treatments over 18 months. The key was organizing the timeline clearly and including objective severity measures. While outcomes vary, thorough documentation consistently strengthens cases.

When facing a Dupixent denial from Humana in California, remember that you have strong appeal rights and multiple pathways to approval. The combination of Humana's relatively low denial rate (3.5%) and California's robust patient protection system creates favorable conditions for well-documented cases.

For complex cases requiring specialized appeal expertise, services like Counterforce Health can help identify specific denial reasons and craft targeted rebuttals using payer-specific workflows and evidence requirements.
