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.


There may be multiple observations with the same revenue code for a discharge record in the Minnesota charge file. Minnesota provided the information on the date of service for each line item charge detail record with revenue code. The number of days from admission were calculated by subtracting the admission date from the service date. If the date was missing or an invalid date, the day of service is missing. The original service dates are not retained on the HCUP database.
