Medicare is the hospital and medical insurance program sponsored by the US Government. Once members of the IDB Group Medical Benefit Program become eligible members of Medicare Part B, coordination of benefits between both programs start to take effect. Medicare becomes the primary insurer and the IDB Group Medical Benefit Program the secondary insurer.  

Enrollment in Medicare Part B is mandatory for participants of the IDB Group Medical Insurance Program at age 65. The plan reimburses the cost of the Medicare Part B premium to eligible participants.  

P&A Group handles Medicare Part B reimbursements for enrolled participants and their eligible dependents on behalf of the IDB.
