As we move out of the Annual Enrollment Period and into ROY (rest-of-year) Medicare enrollment period, it is important to make sure you are using the correct Special Election Period on the Medicare Enrollment Application. There is always a lot of confusion about which SEP Reason and Code to use on the application, and rightfully so since the wrong SEP code can get the application kicked back as incorrect.

Unfortunately, things did not get easier since the Centers for Medicare and Medicaid Services (CMS) have recently published numerous changes to election codes for Plan Year 2019. Yes, you read that correctly! Time to learn more SEP Codes. Luckily, we have already done some leg work reading through the various changes and have summed up the information for you as a cheat sheet.


Important Notes:

  1. If you are reading this before 1/17/2019, then it is important to note that not all codes updates will have taken place in the electronic applications and you will need to use SEP-OTH and indicate the “reason code” from below if you don’t see an applicable SEP on the list. 
  2. If you are an avid paper application user, then you will notice that not all SEPs are itemized. If you do not see an applicable SEP on the paper application, then you must use SEP-OTH and indicate ‘reason code’ as indicated below.
  3. Make sure you are using the correct code for Paper vs. Electronic application. They can differ.
