Common Denial Reasons & How to Fix Them

Denial Reason How to Overturn
"Age criteria not met" Submit birth certificate showing patient under 24 months at proposed infusion date
"Genetic testing incomplete" Provide full SMN1 gene analysis report with bi-allelic mutations clearly documented
"Positive AAV9 antibodies" Request retest if borderline; consider alternative timing if levels may decrease
"No steroid protocol" Submit detailed prednisolone administration plan per FDA requirements
"Non-certified facility" Confirm treatment site is Novartis-certified; provide facility credentials
"Experimental/investigational" Cite FDA approval date (May 2019) and current prescribing information
From Our Advocates: In cases we've supported, the most successful appeals included both the genetic lab report and a detailed timeline showing disease progression. One family's neurologist included photos documenting motor function decline over 3 months, which helped demonstrate urgency for the external review panel.

When Standard Coverage Fails: External Review

Michigan's external review process through the Department of Insurance and Financial Services (DIFS) provides an independent medical review when Aetna denies coverage. This is particularly important for high-cost specialty medications like Zolgensma.

Key Advantages of Michigan's System:

  • Independent medical experts review the case
  • Decision is binding on Aetna
  • No cost to the patient
  • Expedited process available for urgent cases

What the External Reviewer Considers:

  • Medical necessity based on FDA-approved indications
  • Appropriateness of denial under your specific policy
  • Clinical evidence supporting treatment
  • Whether delay would cause harm

Counterforce Health specializes in helping patients navigate these complex appeal processes, turning insurance denials into targeted, evidence-backed appeals that align with both FDA requirements and payer-specific criteria.

FAQ: Michigan-Specific Questions

How long does Aetna prior authorization take in Michigan? Standard requests: 72 hours. Expedited requests: 24 hours. Michigan law requires adherence to these federal timelines.

What if Zolgensma isn't on Aetna's formulary? Request a formulary exception through the prior authorization process. Include medical necessity documentation and FDA approval information.

Can I get expedited review if my child is approaching age 2? Yes. The approaching age limit can qualify for expedited review. Your neurologist must provide documentation of urgency.

Does Michigan have step therapy protections? Michigan doesn't have specific step therapy override laws, but medical exceptions are available through Aetna's internal process and external review.

What's different about ERISA self-funded plans? Self-funded employer plans may not be subject to Michigan's external review process. Check your Summary Plan Description for appeal procedures.

How do I know if I have Healthy Michigan Medicaid vs. commercial Aetna? Check your insurance card. Healthy Michigan Plan cards will indicate Medicaid coverage and have different appeal rights including fair hearings.

What happens if DIFS external review denies coverage? The decision is typically final, though you may consult with an attorney about federal court options for ERISA plans.

Can I switch from Aetna to another insurer for better coverage? Only during open enrollment periods or qualifying life events. Pre-existing condition exclusions don't apply under the ACA.
