Medicare Advantage Plans

Medicare Advantage plans offer all the coverage of Original Medicare — plus benefits not covered by Medicare or most Medicare Supplement insurance plans, including built-in prescription drug coverage and extra health and wellness options. Blue Cross and Blue Shield of Illinois (BCBSIL) offers both individual and group Medicare Advantage plans.

  • The Blue Cross Medicare Advantage (HMO)SM plan offers health coverage to members who reside in Cook, DuPage, Will and Kane counties.
  • The Blue Cross Medicare Advantage (PPO)SM plan offers health coverage to members who reside in  Cook, DuPage, Will and Kane counties.
  • For more details about our Medicare Advantage plans including names, network summary and geographic areas, see the Government Programs Networks and Benefit Products.

Our strong brand recognition and our historical relationship with Medicare makes BCBSIL an excellent choice for Medicare-eligible individuals. We maintain and monitor a network of participating providers including physicians, hospitals, skilled nursing facilities, ancillary providers and other health care providers through which members obtain covered services.

Medicare Group Plans

  • Our retiree group Medicare plans are Blue Cross Group Medicare Advantage (PPO)℠, Blue Cross Group Medicare Advantage Open Access (PPO)℠ and Blue Cross Group MedicareRx (PDP)℠.
  • Out-of-network providers: If you see Medicare members or accept Medicare assignment and are willing to bill BCBSIL, you may treat Blue Cross Group Medicare Advantage Open Access (PPO)SM as an out-of-network provider. Out-of-network providers will be paid the Medicare-allowed amount less any member cost-sharing. In-network providers will be paid at their contracted rate.
