Understanding Your Prescription Drug Coverage 

Choosing a Blue Cross MedicareRx plan from Blue Cross and Blue Shield of Illinois is a smart move. We’ll make sure you have the right resources to help you understand your plan and learn how to get the most from it.

Is My Care Covered?

It’s easy to ask questions or voice concerns about Blue Cross MedicareRx coverage. If you have questions about what the plan covers, you can:

  • Read the Evidence of Coverage (EOC): This important document is in the Welcome Kit you will receive in the mail after you enroll. The EOC explains what is covered, what you pay as a member of the plan, and how to file a complaint if you are not satisfied with a decision or treatment. It is also available for download on the Plan Documents page.
  • Call Customer Service: After becoming a member, call the number listed on your member ID card to speak with a representative who can explain your plan benefits.

Medicare Organization/Coverage Determination, Appeals and Grievances

Blue Cross MedicareRx plans have processes in place to address Medicare coverage issues, complaints, and problems. If you have issues, complaints or problems with your Medicare plan or the care you receive, you have the right to file a complaint.

You can find more information on the Drug Coverage, Appeals and Grievances page. 

Prescription Drug Coverage

Drugs covered by Blue Cross MedicareRx plans are listed in formularies (drug lists). Each plan has its own drug list that includes generic and brand name drugs. The list also provides information about drug copays and limitations, such as prior authorization, quantity limit and step therapy.

Drug lists can change, most often in the beginning of each year. Normally, any changes in the drug list are reflected in the list at the beginning of each year.
