The derivedencounter_ed table reconciles all encounter and claim data sources into a unified list of “treat and release” ED visits for a person. Each ED visit is represented with one row. Multiple encounter or claim sources may be rolled into this single row based on a reconciliation algorithm.
See also:
- Galileo Encounter Reconciliation for a description of the algorithm used to derive encounters from claims, encounters, and authorizations based on primarycaresetting.
Usage
This table is useful to query or describe general patterns related to ED utilization. To trend ED visits over time, consider the utilizationperiod table. Columns related to ED visits in the utilizationperiod table are derived from this table.

|
| primarydxcode |
VARCHAR |
The code of the primary diagnosis of the derived encounter.
|
| primarydxccs |
VARCHAR |
The HCUP CCSR category name related to the primary diagnosis of the derived encounter.
|
| primarydxtermid |
INTEGER |
The termid of the primary diagnosis of the derived encounter. This is a reference to a HIEBus term that captures the coded diagnosis sent by the source system. This reference can be used to join to the Terminology Model to determine source details, mappings, and value sets.
|
| primaryprovideridentifier |
VARCHAR |
The identifier of the provider selected by the algorithm as the primary provider.

|
| primaryencounterid |
VARCHAR(38) GUID |
Reference to the source encounter. NULL if a related encounter is not available.
|
| primaryreferralid |
VARCHAR(38) GUID |
Reference to the source authorization. NULL if a related authorization is not available.
|
| primaryclaimdatasource |
VARCHAR |
Datasource of the source claim. NULL if a related claim is not available.
|
| primaryencounterdatasource |
VARCHAR |
Datasource of the source encounter. NULL if a related encounter is not available.
|
| primaryreferraldatasource |
VARCHAR |
Datasource of the source authorization. NULL if a related authorization is not available.
|
| isavoidable |
BOOLEAN |
True if the primary diagnosis is an Ambulatory Care Sensitive Condition.
