Formulary - drugs in the plan

Each Medicare prescription drug plan has a list of drugs it covers. This list is called a formulary. Access these drugs lists covered in our Medicare Advantage, and Medicare Prescription Drug Plans.

The Blue Shield of California formulary is developed and updated regularly by the Blue Shield Pharmacy and Therapeutics (P&T) Committee and meets all Medicare requirements for included and excluded drugs. The Blue Shield of California Formulary contains medications that have been reviewed and approved by the Food and Drug Administration (FDA).

The Blue Shield P&T Committee includes physicians and clinical pharmacists from our provider and pharmacy networks, and voting members are not employees of Blue Shield of California. To assist physicians in prescribing medically appropriate and cost-effective medications, the P&T Committee reviews medical literature, the FDA drug label, and national treatment guidelines to update the formulary and drug prior authorization criteria. All recommended changes to Blue Shield Medicare formularies and drug prior authorization criteria are first approved by the Centers for Medicare and Medicaid Services (CMS), which provides oversight of the Medicare program.

If your selected plan does not cover a specific drug, you can ask Blue Shield of California to make an exception to the rules that govern coverage. Visit Coverage determinations and exceptions page for more information
