Custom Drug List

Refer to the Custom Drug List (PDF) when prescribing medications for members with three-tier or closed (managed) drug list plans. Under the closed (managed) drug list benefit design, drugs listed as tier three (non-preferred brand) are not covered unless we authorize them as medically necessary. 

You can also use the Custom Drug List Quick Guide (PDF) to find the medications within the most commonly prescribed therapeutic classes. 

Certain drugs on the list may also require prior authorization or step therapy

Drug list updates

The custom drug list is updated twice a year. Since a drug's status may change and new drugs may be added, we also publish a list of updates to keep you informed of those changes.

For the most recent drug list updates, including the custom drug list, read our Drug List Updates (PDF).

Drug list exclusions

The drugs on this list are not covered on the commercial Blue Cross Blue Shield drug lists. The preferred alternatives on this list have similar effectiveness, quality and safety, but at a fraction of the cost. For the most recent list of excluded drugs, read our Drug List Exclusions (PDF)
