A practical preparation schedule

1

About 6 months before

Start learning the difference between Original Medicare and Medicare Advantage. Make a list of physicians, hospitals and prescriptions that matter to you.

2

About 3 months before

Your Initial Enrollment Period generally opens. Confirm whether you'll be automatically enrolled or need to actively sign up.

3

Before Medicare coverage begins

Decide how you want to receive Medicare benefits and consider prescription coverage and, if using Original Medicare, whether Medicare Supplement insurance fits your needs.

4

After Medicare begins

Confirm your coverage is active, update healthcare providers and pharmacies, and keep your Medicare and insurance documents organized.

Still working at 65?

This calculator shows the standard age-65 Initial Enrollment Period. If you or your spouse have qualifying health coverage based on current employment, different enrollment rules may apply.

Have an HSA?

Medicare enrollment can affect your eligibility to contribute to a Health Savings Account. If you're working past 65 and contributing to an HSA, review Medicare timing before enrolling.
