Type of Request



For the types of requests listed below, your prescriber MUST provide a statement supporting the request. Your prescriber can complete the “Supporting Information for an Exception Request or Prior Authorization” section of this form.







Do you need an expedited decision?

If you or your prescriber believe that waiting 72 hours for a standard decision could seriously harm your life, health, or ability to regain maximum function, you can ask for an expedited (fast) decision. If your prescriber indicates that waiting 72 hours could seriously harm your health, we’ll automatically give you a decision within 24 hours. If you don’t get your prescriber's support for an expedited request, we’ll decide if your case requires a fast decision. (You can’t ask for an expedited decision if you’re asking us to pay you back for a drug you already received.)

If you have a supporting statement from your prescriber, attach it to this request.
