If you are planning to keep the Anthem Blue Cross Plan sponsored by the Insurance and Benefits Trust (IBT) of PORAC as your supplemental coverage to Medicare, you don’t need to sign up for Part D with MediCare. However, to maintain your prescription coverage, you must complete the Anthem Blue Cross MedicareRx (PDP) form. You must also contact CalPERS to update your status to MediCare recipient. Please note that under no circumstance are you allowed to sign up with another Part D provider as it may lead to the cancellation of your health care coverage thru CalPERS!
