Prior authorization (PA) and step therapy (ST) encourage safe, cost-effective medication use by allowing coverage when certain conditions are met. A team of physicians and pharmacists develops and approves the clinical programs and criteria for medications that are appropriate for PA and ST by reviewing U.S. Food and Drug Administration (FDA) approved labeling, scientific literature and nationally recognized guidelines.
Prime Therapeutics, our pharmacy benefit manager, conducts all reviews of PA and ST requests from physicians for Blue Cross and Blue Shield of Illinois (BCBSIL) members with prescription drug coverage.
Physicians must complete and submit a request form for all PA and ST medications. Benefits will apply if the member meets specified criteria. If criteria are not met, the member may still choose to receive the medication and will be responsible for the full cost. The final decision regarding what medicines should be prescribed, regardless of benefit determination, is a decision between the patient and their physician.
Not all prescription drug benefit plans include the PA/ST program, and the drug categories may vary depending on the member’s plan. If there are questions regarding prescription benefit coverage, please call the phone number on the back of the member’s BCBSIL ID card.
