Medicare and Medicaid Enrollment

Medicare Parts A and B

There are specific timelines to follow when signing up for Medicare. When newly eligible for Medicare, there is a seven-month enrollment period. This period starts three months before turning 65 and ends three months after including birth month.

Part A is “free,” sign up for it anytime during or after the initial enrollment period. Anyone who has paid Medicare taxes (taken out of payroll checks) is eligible.

People who missed signing up for Parts A and B during the seven-month period won’t be able to sign up again until January 1st of each year. The General Enrollment period is January 1 to March 31 every year. Sign up during this time and coverage will kick on July 1.

***Social security or Railroad Retirement beneficiaries are exempt from these deadlines. People who qualify automatically get enrolled in Medicare Parts A and B. 

While Medicare Part A is “free,” Medicare Part B requires you to pay a monthly premium. Part B coverage is optional and there is a monthly premium. To decline Part B, follow the instructions on the back of your Medicare card.

If you want to sign up for Medicare you can apply at a Social Security office or online.

Medicare Advantage

Some people choose to enroll in a Medicare Advantage Plan.  This type of plan replaces Medicare Parts A and B and is purchased from a private company.  These types of plans are subject to high out of pocket exposure.

Part D

The prescription (Part D) portion of Medicare is not automatic. You have to elect to receive this coverage.  Those who fail to do so may be subject to late enrollment penalty.

Medicare Supplement (Medigap)

Choosing to get Medicare Supplement (Medigap) insurance when signing up for Medicare is another option. Typically these plans offer the most comprehensive coverage to Medicare.


Policyholders who don’t sign up for Medicare Parts B and D might have to pay a late fee for failing to meet Medicare deadlines.
