I don't want to enroll in Medicare because I already have such great coverage under the SAG-AFTRA Health Plan and I can't afford the Medicare Part B premiums. Do I have to enroll in Medicare Parts A and B?

Yes. You are required to enroll in Medicare Parts A and B when Medicare is your primary coverage and the SAG-AFTRA Health Plan is secondary. If you fail to enroll in Medicare, the Plan's benefits are reduced by 80%. See the Medicare Parts A, B & D Notice for more information.
