CDC provides documents to assist with implementing HL7 message mapping guides and sending case notifications to NNDSS.
| PHIN Messaging Specification for Case Notification v3.1 | This document has been updated to accommodate sending the Generic and disease-specific Message Mapping Guides (e.g., hepatitis, sexually transmitted diseases, congenital syphilis, pertussis, and mumps) and should be used with all new MMGs beginning in 2019 |
| Laboratory Template (5/11/2018) | This document includes the data elements for the “Laboratory Repeating Group” in the Message Mapping Guides. |
| Generic Data Elements that Define a Unique Case (7/7/2017) | Information for NNDSS reporting jurisdictions about which data elements in the Generic v2.0 MMG cannot change for a case because they are used to define a unique case in the CDC MVPS for HL7 case notifications |
| Methods for Conveying Unknown Values in Case Notification | Guidelines that address the methods for data transmission in HL7 messages when the information is collected in the surveillance system |
