SPECIAL MESSAGE FOR INDIVIDUAL APPLYING FOR PART B
This form is your application for Medicare Part B (Medical
Insurance). You can use this form to sign up for Part B:
• During your Initial Enrollment Period (IEP) when you’re
first eligible for Medicare
• During the General Enrollment Period (GEP) from
January 1 through March 31 of each year
• If you’re eligible for a Special Enrollment Period (SEP),
like if you’re covered under a group health plan (GHP)
based on current employment.

Initial Enrollment Period
Your IEP is the first chance you have to sign up for Part B.
It lasts for 7 months. It begins 3 months before the month
you reach 65, and it ends 3 months after you reach 65. If you
have Medicare due to disability, your IEP begins 3 months
before the 25th month of getting Social Security Disability
benefits, and it ends 3 months after the 25th month of
getting Social Security Disability benefits. To have Part B
coverage start the month you’re 65 (or the 25th month of
disability insurance benefits); you must sign up in the first 3
months of your IEP. If you sign up in any of the remaining 4
months, your Part B coverage will start later.

General Enrollment Period
If you don’t sign up for Part B during your IEP, you can sign
up during the GEP. The GEP runs from January 1 through
March 31 of each year. If you sign up during a GEP, your
Part B coverage begins July 1 of that year. You may have to
pay a late enrollment penalty if you sign up during the GEP.
The cost of your Part B premium will go up 10% for each
12-month period that you could have had Part B but didn’t
sign up. You may have to pay this late enrollment penalty as
long as you have Part B coverage.

Special Enrollment Period
If you don’t sign up for Part B during your IEP, you can
sign up without a late enrollment penalty during a Special
Enrollment Period (SEP). If you think that you may be eligible
for a SEP, please contact Social Security at 1-800-772-1213.
TTY users should call 1-800-325-0778 You can use a SEP when
your IEP has ended. The most common SEPs apply to the
working aged, disabled, and international volunteers.
Working Aged/Disabled
You have a SEP if you’re covered under a group health plan
(GHP) based on current employment. To use this SEP, you
must:
• Be 65 or older and currently employed
• Be the spouse of an employed person, and covered under
your spouse’s employer GHP based on his/her current
employment
• Be under 65 and disabled, and covered under a GHP
based on your own or your spouse’s current employment
• Be under 65 and disabled, and covered under a GHP
based on your own or your spouse’s current employment
You can sign up for Part B anytime while you have a GHP
coverage based on current employment or during the 8
months after either the coverage ends or the employment
ends, whichever happens first. If you sign up while you have
GHP coverage based on current employment, or, during the
first full month that you no longer have this coverage, your
Part B coverage will begin the first day of the month you
sign up. You can also choose to have your coverage begin
with any of the following 3 months. If you sign up during
any of the remaining 7 months of your SEP, your Part B
coverage will begin the month after you sign up.
NOTE: COBRA coverage or a retiree health plan is not
considered group health plan coverage based on current
employment.
International Volunteers
You have a SEP if you were volunteering outside of the
United States for at least 12 months for a tax-exempt
organization and had health insurance (through the
organization) that provided coverage for the duration of the
volunteer service.
