Important Update

Explanation of Payments (EOPs) have been regenerated for claim processing dates January 1, 2023, through December 6, 2023, to include corrected information and additional details to help aid in processing and posting prior payments received. The contents of these EOPs are associated with a prior payment and the EOP contents may contain updated information about the payments and claims.  The details can be matched to prior payments based upon the payment date included on the first summary page and/or a claim number within the details. 

These EOPs are located within Zelis and are available for your practice to review or abstract, based on practice preference.  We have included instructions on how to create an account with Zelis in the event you do not already have one. 

If you do not wish to view the EOP within Zelis, you may also view the most recent claim status, including EOP, on our Provider Portal.  The portal can be accessed via the following link:  HealthTrio connect - connect Login.  If you require help in registering for the provider portal, please follow the link to access training materials and the link to register: HealthTrio Provider Portal - Overview | Rise 360 (

If you have any questions specific to the EOP contents, please contact customer service at (855) 645-8448 or email or
