How long does Aetna CVS Health renewal take? Standard renewals typically take 14-30 days. Expedited reviews with documented medical urgency receive decisions within 72 hours.

What if my specialist is no longer available? Aetna requires renewal requests from specialists familiar with HAE management. Transfer care to another qualified allergist/immunologist before your authorization expires.

Can I renew early if I'm traveling? Yes, submit renewal requests up to 90 days before expiration if you have documented travel or access concerns.

What happens if Haegarda becomes non-formulary? File a formulary exception request with clinical justification. If denied, use New York's external appeal process for independent review.
