  2. For Philadelphia chromosome-positive (Ph+) cases: Prior tyrosine kinase inhibitor trial (imatinib, dasatinib, nilotinib, or ponatinib)
  3. Salvage therapy attempts when clinically appropriate

Medical Exceptions

Step therapy can be overridden when:

  • Prior treatments are contraindicated due to medical conditions
  • Patient experienced severe intolerance to required therapies

  • Baseline liver function tests (AST, ALT, bilirubin, alkaline phosphatase)

CVS Specialty Pharmacy Requirements

  2. CVS Specialty contacts patient within 24-48 hours of approval

  4. Delivery coordination to approved infusion site

Site of Care Requirements

Besponsa administration is restricted to:

Home infusion is generally not permitted due to the drug's toxicity profile and monitoring requirements.

Appeals Process in California

California offers robust appeal rights through the Department of Managed Health Care (DMHC) with high success rates for specialty drug denials.

Internal Appeal (First Level)

  1. File grievance with Aetna within 180 days of denial
  2. Standard review: 30 days for determination
  3. Expedited review: 72 hours for urgent cases
  4. Required documents: Denial letter, medical records, physician support letter

Independent Medical Review (IMR)

If internal appeal fails, California residents can request IMR through DMHC:

  • Success rate: Approximately 73% of requests result in coverage approval
  • Timeline: 45 days for standard review, 7 days for expedited
  • Cost: No fee to patients
  • Process: Independent oncology experts review case
  • Binding decision: Aetna must comply with favorable IMR rulings
From our advocates: We've seen multiple Besponsa denials overturned at IMR when the clinical team provided comprehensive documentation of CD22 positivity, prior treatment failures, and a detailed hepatic monitoring plan. The key is demonstrating that standard treatments have been tried and that the patient meets FDA-approved criteria exactly.

Frequently Asked Questions

How long does Aetna prior authorization take for Besponsa in California? Standard determinations typically take 30-45 days, while expedited reviews for urgent cases are completed within 72 hours. CVS Specialty reports that over 95% of eligible prior authorizations are approved within 24 hours once complete documentation is submitted.

What if Besponsa is non-formulary on my Aetna plan? Non-formulary drugs can be covered through formulary exception requests. Your oncologist must demonstrate medical necessity and provide clinical justification for why formulary alternatives are inappropriate.

Can I request an expedited appeal if my condition is urgent? Yes. California law requires expedited appeals for urgent cases where delay could seriously jeopardize your health. Contact Aetna member services and specifically request expedited review.

Does step therapy apply if I've failed treatments outside California? Treatment history from any state counts toward step therapy requirements. Ensure your oncologist includes comprehensive records from all previous providers.

What happens if my Aetna appeal is denied? California residents can request Independent Medical Review through DMHC at no cost. IMR decisions are binding on Aetna and have a high success rate for medically appropriate requests.

How do I find an in-network oncologist for Besponsa treatment? Use Aetna's provider directory online or call member services. Ensure the provider has experience with acute leukemia and can perform IV chemotherapy administration.
