Electronic Media Claims for new east region

Electronic Data Interface

Information and timeline for TRICARE provider applications for electronic claims submissions

Humana Military was awarded the new East Region contract for TRICARE with an effective date of January 1, 2018. Wisconsin Physicians Services (WPS) will be the new fiscal intermediary/claims processor for TRICARE in the new East Region. The new East Region is a merger of the existing TRICARE North and TRICARE South Regions, which includes the following states: Alabama, Arkansas, Connecticut, Delaware, the District of Columbia, Florida, Georgia, Illinois, Indiana, Iowa (Rock Island area), Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri (St. Louis area), New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Texas (excluding El Paso area), Vermont, Virginia, West Virginia and Wisconsin.

The transition of provider electronic claims processes, including electronic media claims (EMC), electronic funds transfers (EFT) and electronic remittance advice (ERA), to Wisconsin Physicians Service (WPS) for the new East Region, is underway to ensure all providers are ready for the start of healthcare delivery on or about January 1, 2018.

This page offers provider information on trading partner agreements, EDI/EMC applications and EFT/ERA processes for all providers submitting TRICARE claims electronically. Providers are expected to enroll anew for EMC, ERA, and EFT through WPS. Electronic interface with the current fiscal intermediary/claims processor will not transfer.

Jointly, Humana Military and WPS will make every effort to assist providers in a smooth transition of claims processing. The following is a full explanation of the provider registration process for EDI/EMC that will be made available starting April, 2017.

Alternate online claims entry portal

  • The Humana Military secured provider portal will also offer an online claims entry option that will allow TRICARE East providers to enter and submit claims. More information will be provided when the online option becomes available.
Please note: No LIVE claims submissions to WPS from current TRICARE providers are allowed until January 1, 2018. This early EDI/EMC campaign is to ensure providers are ready. 

EDI set-up with WPS

WPS requires that all electronic providers/groups sign, and have on file, a Trading Partner Claims Agreement (“Agreement”) prior to submission of electronic claims.

All providers that will submit EDI claims directly to WPS will need to complete a self-registration process that includes an initial registration and the necessary request forms and business agreement(s).

PC-Ace Pro32 software users

If you are currently using PC Ace software to submit your claims, you will need to upgrade to the current version of PC ACE. If you do not use PC ACE and would like to, please download our new WPS version.
