From Our Advocates

We've seen many Virginia families succeed by being proactive with documentation. One family gathered all their son's metabolic specialist reports, genetic testing, and functional assessments before the initial PA submission. When Aetna requested additional information, they had everything ready within 24 hours, avoiding treatment delays. The key was treating the PA process like building a legal case from day one.

FAQ

How long does Aetna CVS Health prior authorization take in Virginia? Standard PA decisions take 7-14 business days. Expedited reviews (when urgent medical need is documented) are decided within 72 hours.

What if Elaprase is non-formulary on my plan? Request a formulary exception by documenting medical necessity and lack of formulary alternatives. Since no other FDA-approved ERT exists for MPS II, this is often successful.

Can I request an expedited appeal if treatment is delayed? Yes, if your prescriber certifies that delay could seriously jeopardize your health. Aetna must decide expedited appeals within 72 hours.

Does step therapy apply if I've tried treatments outside Virginia? Prior treatment history from other states should be accepted. Provide complete medical records documenting previous therapies and outcomes.

What happens if I move from Virginia to another state? External review rights vary by state. Contact your new state's insurance department for specific appeal processes and deadlines.

How often do I need to renew prior authorization? Typically annually, but Aetna may require more frequent reviews. Continuation requires documentation of clinical response or disease stabilization.

Can family members help with appeals? Yes, but you'll need to complete an Authorized Representative form allowing them to act on your behalf with Aetna.

What if my employer plan is self-funded? Self-funded plans may opt into Virginia's external review process. If not, you may have federal external review rights through HHS.
