Arizona Medicare Enrollment Date Calculator

Your Initial Enrollment Period is seven months long: the three months before the month you turn 65, your birthday month, and the three months after. The rules are federal, so they are the same in Arizona as everywhere else.

Signing up in the three months before your birthday month starts coverage on the 1st of your birthday month.

Medicare treats you as turning 65 in the previous month, so your whole enrollment window, and your earliest coverage date, move one month earlier.

It is the six months starting the month you are 65 or older and your Part B begins. During those six months a Medigap insurer cannot turn you down or charge you more because of your health.

Not always. If you or your spouse have job-based coverage from current work, you may be able to delay Part B without a penalty and sign up later during a Special Enrollment Period. The size of the employer matters, so check before you decide.

Your coverage starts on the 1st of the month after you sign up. Only enrolling in the three months before your birthday month gets you coverage on the 1st of that month, so if you want Medicare to begin right at 65 with no gap, apply early in your window. The calculator shows that earliest date for you.

If you already collect Social Security retirement benefits when you turn 65, you are usually enrolled in Part A and Part B automatically, and your Medicare card arrives in the mail. If you have not started Social Security, nothing happens on its own: you sign up yourself through Social Security, online at ssa.gov, by phone or at a local office.

You can usually sign up during the General Enrollment Period at the start of each year, but your coverage starts later and you may owe a Part B late penalty of 10% for each full 12 months you went without it. Unless you have job-based coverage from current work, it is far easier to sign up inside your seven-month window.

If you do not have other creditable drug coverage, usually yes. Going 63 days or more in a row without Part D or creditable coverage after your Initial Enrollment Period ends can add a penalty of 1% of the $38.99 national base premium for each full month you went without, for as long as you have Part D.

No. It is a free planning tool from Rise Up Benefits Group, an independent agency, and it is not connected with Medicare or Social Security. It applies the published federal enrollment rules to your birth date. Your official dates come from Social Security when you apply, and we are glad to check them with you.
