You need to enroll in Medicare Parts A and B when you are retired and age 65 or older, or if you’re retired and certified medically disabled by the Social Security Administration (SSA) and become eligible for Medicare.
If you are currently working for a state agency or higher education institution that participates in the Texas Employees Group Benefits Program (GBP), you can delay your Part B enrollment. Your state health insurance remains primary to Medicare. Most active employees enroll in Medicare Part A because for most it is free. This will give you secondary hospitalization coverage to your state health insurance. If you decide to delay Part B, remember to contact the SSA no more than 90 days before you stop working to start the enrollment process. You will want your Part B to be effective the first of the month following your retirement date or last day of state employment.
Once you are retired and eligible for Medicare, you will want to enroll in Medicare Parts A and B. In most cases, if you are already receiving SSA benefits, you will be automatically enrolled in Medicare Parts A and B. The coverage will be effective the first day of the month you turn 65. The SSA will send you information in the mail. If you are not yet receiving SSA benefits, you will not be automatically enrolled. You will need to contact the SSA during your initial enrollment period and enroll in Medicare Parts A and B. You can enroll up to 90 days before your 65th birthday or after you have been certified disabled by the SSA for 24 month.
