FAQ: Your Top Questions Answered

How long does Aetna CVS Health prior authorization take in Michigan?

Over 95% of complete PA requests are approved within 24 hours when all required documentation is submitted. Incomplete requests may take 30-45 days.

What if Amvuttra is non-formulary on my plan?

You can request a formulary exception by demonstrating medical necessity and showing that formulary alternatives are inappropriate or have been tried and failed.

Can I request an expedited appeal if my condition is worsening?

Yes, Michigan allows expedited external appeals within 72 hours if your physician certifies that delay would seriously jeopardize your health.

Does step therapy apply if I haven't tried other TTR therapies?

Aetna may require documentation of why other TTR-targeting therapies (like tafamidis) are inappropriate rather than requiring you to fail them first, especially if there are medical contraindications.

What happens if my external review is denied?

You have 60 days to seek judicial review in Michigan circuit court, though this step is rarely necessary as external reviews have high overturn rates for medically necessary treatments.

How often do I need to renew my Amvuttra authorization?

Initial approvals are typically for 9 months, with 12-month renewals if you show improvement or stabilization in neuropathy measures, gait, nutritional status, or quality of life.

Can my doctor handle the appeal process for me?

Yes, your physician or another authorized representative can file appeals on your behalf with your written consent. This is often more effective as they can provide clinical context.

What if I move from Michigan to another state?

Your external review rights will change based on your new state's laws. Most states have similar processes, but timelines and procedures vary.
