TRICARE updates for 2018

As of January 1, 2018, TRICARE South and TRICARE North will merge to form TRICARE East. TRICARE North and TRICARE South are now TRICARE East so be mindful of the change when looking up Insurance Providers in SimplePractice


Claims with Dates of Service up to 12/31/2017 will have to be submitted to TRICARE South (TRSTH) or TRICARE North (38520) the way you've always done it. 

Important: Do not submit claims that include 2018 DOS to these two payers.


Claims with Dates of Service of 01/01/2018 and after will have to be submitted to TRICARE East (TREST). 

Note: TRICARE East (TREST) requires for you to submit an enrollment in order to file claims electronically.

Here's how you can submit your enrollment:

  1. Select a single client and assign TRICARE East (TREST) as their insurance company.Claims must now be submitted to TRICARE East or TREST for short
  2. Go to My Account > Settings > Insurance Providers > search for TREST > +Enroll. Make sure the information on that page is the information TRICARE has on file for you. 
  3. Our clearinghouse will submit the required paperwork to the payer on your behalf. We will email you when your enrollment has been completed or if there are any other steps needed from you in order to complete this process. 

Tip: Once you have submitted all of your claims for 2017 to both TRICARE South and TRICARE North, make sure you update your clients' profiles so that TRICARE East is entered as their new Insurance Company.
