Drug Lists for Group Members
Who is this for?

If you have a PPO or HMO health plan through your employer that includes prescription drug coverage, you can use these drug lists (also known as formularies) to see if your Blue Cross Blue Shield of Michigan plan covers a medication.
Employers with more than 50 full-time employees can choose the prescription drug coverage that goes with the health plans they provide. However, not all HMO and PPO plans share the same drug list, or formulary.
To see if a medication is covered, you'll need to know whether your Blue Cross plan uses Preferred, Clinical, Custom or Custom Select Drug Lists. You can find out by checking your prescription drug benefits by logging into your online account. From there, you'll be able to find out what's covered, how much a medication will cost and compare brand-name prescriptions with generics.
If you can't find your drug list, call the customer service number on the back of your member ID card for help.
Some additional resources can be used with most of our group plans. They're listed below under "Other helpful resources."
