ET3 Model Data Submission Guide

The ET3 Model requires that Participants regularly submit data in addition to the Medicare claims information used as part of billing for ET3 Model interventions. NEMSIS standard electronic Patient Care Report (ePCR) data are an important and large component of ET3 Model data submissions.

NEMSIS standard ePCR data are a new quantitative data source for the ET3 Model and the Center for Medicare and Medicaid Innovation (CMMI) at the
Centers for Medicare and Medicaid Services (CMS). However, the data source is very familiar to participating EMS ambulance suppliers and providers, and their supporting software vendors.

Thus, the main goal of this guide is to familiarize Participants and their supporting vendors with the submission of NEMSIS standard ePCR data into ET3 Model systems and confirmation that the ET3 Model has correctly received that data.

The decision to revise the National EMS Data Standard is initiated by the need to update the standard to accurately reflect changes in EMS service and care. Abundant consideration is given to the consequences a revision has on clinicians, EMS agencies, States, Territories, and EMS Software Vendors.

Significant collaboration among many different stakeholder groups is required to warrant the need for a revision, and then to ensure the practicality and usefulness of the proposed changes. The process, on average, is a four-year cycle of collaboration and balloting potential revisions including proposal collection, review, posting, and implementation of a new data standard.

Information includes how decisions are made including the extensive collaboration that take place to fine-tune the data standard for completeness, efficiency, and ease of use for the field clinicians.

National Infectious Disease Elements/Values

In response to the 2020 COVID-19 epidemic, the NEMSIS TAC was directed to develop National Custom Elements and Values that would aid in the identification of potential COVID-19 infections and improve the characterization of the EMS response to potential infections.
A FAQ describing these Elements and Values can be found here: National Infectious Disease Elements/Values (updated 02/01/2021)

Software Recertification Required Before 2021

The end of the year is fast approaching, so please be advised that you may need to recertify your software to remain compliant on the V3.4.0 NEMSIS Standard. Our new policy requires recertification every two years and takes effect on January 1st, 2021. Keep in mind that if you serve customers in the State of California, they require annual recertification, and your recertification date maybe sooner.

You can find your certification date on the NEMSIS website Compliant Vendors page: Compliant Vendors

To avoid any delays in the certification process, please consider seeking recertification at your earliest convenience, since there will be limited appointments available in December due to the holiday season. If you are unsure of your need to recertify, please contact Laurel Baeder for verification.
