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 n 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 aslong as you have Part B coverage.

Special Enrollment Period

If you don’t sign up for Part B during your IEP, you cansign up without a late enrollment penalty during a SpecialEnrollment 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.
