Birthday: July 25th - Enrollment Period
If you join during:
3 months before birthday month
3 months after birthday month
The later you enroll, the later your Medicare Parts A and B will start.Medicare Part D starts the month of your birthday, or the month after you enroll.
Age 65 and Older and Outside of Initial Enrollment Period
You can still join Medicare:
Special Enrollment Period for Parts A and B. This is for people who've been covered by insurance through a current job (or spouse's current job). You can enroll up to eight months after the job or the insurance ends.
Special Enrollment Period for Part D. This is for people who had prescription drug coverage through a current job (or a spouse's current job) and it was creditable coverage. You can enroll up to 63 days after the job or insurance ends.
General Enrollment Period. This occurs each year from January 1 to March 31. Your coverage starts July 1, and you may have to pay a late-enrollment penalty.
Under Age 65 and Receiving Social Security Disability Benefits
Social Security automatically enrolls you in Medicare Parts A and B.
Generally, this occurs on your 25th month of receiving Social Security disability payments.
Some individuals with disabilities don't have to wait as long, like those with End Stage Renal Disease (also called permanent kidney failure) or people with Amyotrophic Lateral Sclerosis (also called ALS or Lou Gehrig's Disease).
Medicare will let you know the effective date, and give you the option to defer Part B.
