HL7 - MDM Message

MDM (Medical Document Management)

An MDM message can be created in relation to or independently of an order. There are 11 different MDM message trigger events. These events always include the status of the document and can also include the accompanying document itself:

MDM^T01 - Original Document Notification
MDM^T02 - Original Document Notification with Content
MDM^T03 - Document Status Change Notification
MDM^T04 - Document Status Change Notification with Content
MDM^T05 - Document Addendum Notification
MDM^T06 - Document Addendum Notification with Content
MDM^T07 - Document Edit Notification
MDM^T08 - Document Edit Notification with Content
MDM^T09 - Document Replacement Notification
MDM^T10 - Document Replacement Notification with Content
MDM^T11 - Document Cancel Notification

MDM messages are typically used by Radiology departments to communicate provider transcriptions, order information and document contents. These messages either update other healthcare systems to identify available reports in the transcription system and can also provide the documents contents. The most commonly used MDM message is the MDM-T02, similar to an HL7 ORU Result Message, notifying a system of the creation of a document and providing the document contents.

Segment	Description
MSH	Message Header. This segment is a mandatory part of an MDM message, and contains information about the message sender and receiver, the date and time that the message was created. This segment is required.
EVN	Event Type. Communicates the event that occurred in order for the message to be generated. This segment is a crucial part of the data flow, as it indicates where and when a message is sent based on the type of event. This is a required segment.
PID	Patient Identification. An MDM message is a patient-specific message type, and must be linked to a particular patient. Therefore, patient information such as the patient identifier, name, date of birth, etc. must be included in an MDM. This segment is required.
PV1	Patient Visit. Contains information about patient visit details such as servicing facility, attending doctor, and visit ID. This segment is required.
TXA	Document Notification. Communicates information specific to a transcribed document as a result of a status change. This segment does not include the document contents and is required.
{OBX}	Observation Segment. Contains the document contents. This segment is required and is often repeating segments in an MDM.
[ ] = optional, { } = repeating

Working With MDM Messages

Are you working with HL7 MDM messages? In order to successfully process these messages, it's important to understand the specific format that the sending and receiving facilities are expecting the MDM messages to adhere to. Discrepancies can occur due to the version of HL7, system input error, or even simply human error when the messages were created.
