Prior Authorization and Step Therapy
To ensure that members receive the most appropriate and cost-effective drug therapy, some plans require that additional steps be taken before certain drugs are covered:
- Prior Authorization: Certain clinical criteria must be met before some drugs are covered. Your doctor should call our pharmacy help desk to request prior authorization for these drugs.
- Step Therapy: Requires that you have tried an alternative therapy first or that your doctor has clinically documented why you cannot take the alternate therapy. Step therapy may include select covered over-the-counter products.
