Common Questions (FAQ)

How long does Aetna CVS Health PA take in North Carolina? Standard requests: 72 hours. Expedited requests: 24 hours. If Aetna doesn't respond within these timeframes, the request is automatically approved.

What if Orfadin is non-formulary on my plan? Request a formulary exception with medical necessity documentation. Emphasize FDA approval for HT-1 and lack of therapeutic alternatives.

Can I request an expedited appeal? Yes, if delays would seriously jeopardize your health or ability to regain function. Your physician must certify the urgent medical need.

Does step therapy apply to Orfadin? Some plans may require trial of generic nitisinone first. Document any failures, intolerances, or contraindications to generic formulations.

What happens if I move within North Carolina? Coverage should continue if you remain on the same Aetna plan. Notify CVS Specialty of address changes for shipping.

Can I appeal if I disagree with quantity limits? Yes, if your physician documents medical necessity for higher doses within FDA limits (maximum 2 mg/kg/day for HT-1).
