Tennessee NEMSIS v3 Conversion

Table of Contents


 Implementation of custom requirements and elements for Tennessee begins.

 the NEMSIS v3 validation was enabled for all of Tennessee. EMS Services are presented with error messages when advancing charts, but are not required to complete all the errors at the time. 

 Enforcement of validation rules, requiring correction by crews if encountered, has been scheduled for Tuesday, October 1st, 2019. 


"Disabling v2" will not affect your charting except that you will no longer be subject to the older v2 validations.  You will not be switching charting applications.

Your Attention Is Required

Tennessee NEMSIS v3 Set-Up Deadline is Approaching

On September 24th, ahead of the October 1st enforcement date, emsCharts will be activating TN NEMSIS validation rules.

What does this mean?

  • Beginning September 24th, EMS crews will begin to see error messages when their documentation does not satisfy the new TN rules.
  • From September 24 until October 1st, validation locks will not be enabled and these error messages will not prevent charts from locking.

Use the time between September 24th and October 1st to do the following:

  • Educate your crew members on the error messages and how to satisfy the requirements. Beginning October 1st, unsatisfied errors WILL prevent the charts from locking.
  • Consider creating service level data validation rules to flag the errors within the chart before they cause a failure when the crew members attempt to lock.
  • If you have questions, please reach out before October 1 when the errors will be enforced and will prevent charts from locking.

Required Steps

  • Prepare configuration for NEMSIS v3.4.0 in emsCharts - see "emsCharts Configuration Requirements" below

emsCharts Configuration Requirements

In addition to the standard NEMSIS v3 mapping requirements (units, outcomes, categories, impressions, etc), the following are required:

  • Onset time

  • Received Time

  • Final Acuity

Verify that your Agency Number (State ID) is entered correctly in your Service Configuration under the Export tab, specifically in the General section.

Remember to map your code tables! As part of the TN conversion to NEMSIS v3.4.0, it is imperative for your Service to be properly configured for NEMSIS v3.4.0 in emsCharts. If you have not already, please go through the NEMSIS v3 Quick Start Guide for detailed information on setting up in NEMSIS v3
