Enrollment period changes in 2023

Initial Enrollment Period (IEP): The IEP is a seven-month period including the three months before, the month of, and the three months following your 65th birthday month. Beginning in 2023, coverage begins the first of the following month (but no earlier than the month you are Medicare-eligible). For example, if your 65th birthday is in April 2023:






General Enrollment Period (GEP): The GEP runs from January 1 through March 31 each year. In the past, your coverage would start on July 1 if you used the GEP. Starting in 2023, your coverage will start the first of the month after you enroll if you use the GEP.


Special Enrollment Periods (SEPs): SEPs are periods of time outside normal enrollment periods when you can enroll in Medicare or change your coverage. Beginning in 2023, new SEPs have been created for people who:

  • Lose Medicaid
  • Are in an area with a disaster or emergency
  • Are released from incarceration
  • Make an enrollment mistake based on misinformation from their employer
  • Experience other exceptional circumstances
