Prior Authorization

Your prescription drug program provides coverage for some drugs only if prescribed for certain uses, durations, and/or quantities. For this reason, some prescriptions must receive prior authorization before they can be covered under your benefit. Either your pharmacist may initiate the review process or you may be asked to request that your doctor initiate the review. It may be required at times for Express Scripts to contact your doctor to get necessary information to determine coverage eligibility. Following the review process, both the member and the physician will be notified as to the results of the review process. If your prescription is found not to be covered, you will be required to pay the full price of the prescription. An appeals process is available in the case of coverage denial.

Specialty Drugs

Specialty medications must be purchased through Accredo®, the specialty pharmacy at Express Scripts, or Duke Specialty Pharmacy to be eligible for coverage under the plan, unless they are medications which are intended for an immediate need. A list of covered specialty drugs as of January 2024 is available here (this listing is subject to change). New users of some specialty drugs will need their physicians to obtain prior authorization from Express Scripts before prescribing the drugs.
