Column Information
Name Type Discontinued?

The line number of the medical history contact within the encounter. Each line of history is stored in enterprise reporting as its own record; a given patient may have multiple records (identified by line number) that reflect multiple lines of history.
2 DX_ID NUMERIC No
The unique ID of the diagnosis record associated with the medical history contact. Note: This is NOT the ICD9 diagnosis code. It is an internal identifier that is typically not visible to a user.
3 MEDICAL_HX_DATE VARCHAR No
The free-text date entered in clinical system’s Medical History window for the diagnosis. This field is free-text due to the imprecise nature of patient-provided historical information.
4 PAT_ENC_CSN_ID NUMERIC No
A unique serial number for this encounter. This number is unique across all patients and encounters in the system.
5 MED_HX_ANNOTATION VARCHAR No
This column contains the medical history annotation.
