General Notes

Line item units (UNITS) are retained as provided by the data source. No edit checks are performed on this data element during HCUP processing.

UNITS are contained in a line item charge detail file. There may be multiple observations in the file with the same revenue code for a discharge record. To identify the total charge and units of service to specific revenue centers, the line item charge (CHARGE) and unit detail (UNITS) for a discharge should be summarized by revenue code (REVCODE) and the HCUP variable KEY which uniquely identifies a discharge. KEY can also be used to merge the detail charge information onto the discharge record in the Core file.

In early 2010, the Kentucky Cabinet for Health and Family Services transitioned to a new data collection entity. During that transition, it was identified that the previous data vendor did not always obtain CPT and Revenue code information. As a result, there are more missing values in 2009 for line item CPTs, Revenue codes, units, charges, and service dates than in previous years.
