Project Purpose

Overview

This page supports the HL7 Contract work for the C-CDA R2.1 Companion Guide Project. This project's goal is to produce a new C-CDA Companion Guide to support C-CDA R2.1 and to provide more context in assisting implementers. The purpose of the new Companion Guide is:

• Supplement the C-CDA R2.1 Implementation Guide to provide additional context to assist implementers and connect them to tools and resources
• Map the common clinical data set (CCDS) to the appropriate C-CDA locations
• Provide technical guidance for representing the 2015 Ed. CEHRT data requirements using the C-CDA Implementation Guide
• Include clinically-valid examples of C-CDA components necessary to meet 2015 Ed. CEHRT requirements
• Recommend an approach to implementations using the C-CDA IG to meet the needs of clinicians and achieve ONC Certification
