Beginning in 2006, please see REVCHGn for detailed charge information. CHGn is no longer included in KY SID.

Detailed charges (CHGn) are associated with identified revenue centers (REVCDn) and units of service (UNITn). For example, CHG1 applies to the revenue center in REVCD1 and the units of service specified in UNIT1. Kentucky reports detailed charges (CHGn) associated with standard UB-92 revenue codes stored in REVCDn. Kentucky does not collapse or redefine ranges of revenue codes.

In addition, prior to data year 2005, information on total charges (revenue center 001) was removed from the detailed charge arrays. (CHGn, REVCDn, and UNITn). Information on total charges is available in the HCUP variables TOTCHG and TOTCHG_X.

Detailed charges (CHG1-CHG33) are associated with the identified revenue centers (REVCD1-REVCD33), and units of service (UNIT1-UNIT3). For example, CHG1 applies to the revenue center in REVCD1 and the units of service specified in UNIT1. Revenue codes are available for accommodation and ancillary charges. Units are available for accommodation charges.

The charge detail provided by Massachusetts varies across years.

• Starting in 2007: Detailed charges (REVCHGn) are associated with the UB-92 revenue centers (REVCDn), and units of service (UNITn). For example, REVCHG1 applies to the revenue center in REVCD1 and the units of service are specified in UNIT1.



• Starting in 1999: Detailed charges (CHGn) are associated with the UB-92 revenue centers (REVCDn), and units of service (UNITn). For example, CHG1 applies to the revenue center in REVCD1 and the units of service are specified in UNIT1. Massachusetts provides 110 revenue codes, detail charges, and units, but not all revenue centers (REVCDn) have an associated charge (CHGn = .). During HCUP processing, the array of revenue codes, charges, and units are condensed so that only the revenue codes that have non-missing charges are retained. No information is lost.



• In 1998: Detailed charges (CHGn) are associated with the UB-92 revenue centers (REVCDn), and units of service (UNITn). For example, CHG1 applies to the revenue center in REVCD1 and the units of service are specified in UNIT1. Massachusetts provides 110 revenue codes, detail charges, and units, but not all revenue centers (REVCDn = .) have a charge (CHGn = .). The revenue codes are constant across records. For example, REVCD1 = 111 on all discharges even if there is no charge (CHG1 = .) for that revenue center.



• Prior to 1998: Revenue codes are not retained on the discharge record. The detailed charges and units are retained on the HCUP files in assigned positions. For example, CHG1 is always for UB-92 revenue code 111 "Routine Medical/Surgical." See the variable note for CHGn for more details.

Because of the timing of HCUP data processing for the 1999 NIS, the Massachusetts source file provided to HCUP was an interim file that included records that had failed edit checks. The percent of failed records is very small, ranging from 0.0% to 1.5% (with a mean of 0.4%) for most hospitals. A handful of hospitals had a large percent of failed records. Failed records have one or more of the following errors:

• Invalid diagnosis code *
• Invalid procedure code *
• Invalid or missing birth weight
• Invalid claim certificate number **
• Invalid or inconsistent UB-92 revenue code
• Invalid medical record or person number
• Invalid type of payer *
• Inconsistent primary and secondary payer
• Invalid physician identifier
• Invalid patient or employer ZIP Code. **

* These errors would have been handled during HCUP data processing.

** These data elements are not included in the HCUP data files.

Detailed charges (CHGn) are associated with the identified revenue centers (REVCDn) and units of service (UNITn). For example, CHG1 applies to the revenue center in REVCD1 and the units of service specified in UNIT1.

In the rare event that there were more revenue charges than could be retained in the array of revenue codes, charges, and units, Nevada set the revenue code to "9999", the charge to the sum of the remaining charges, and the units to the sum of the remaining units.

Beginning in 2002, detailed charges (CHGn) are associated with the identified revenue centers (REVCDn) and units of service (UNITn), and daily rates (RATEn). For example, CHG1 applies to the revenue center in REVCD1, the units of service specified in UNIT1, and the rate in RATE1. North Carolina reports detailed charges (CHGn) associated with standard UB-92 revenue codes stored in REVCDn.

In 2004, the revenue codes provided by the Partner organization were missing the leading zeros. For example, a value of 1 should be considered "0001" indicating total charges and a value of 450 should be considered 0450 for emergency room.

For 2002-2003 data, charge detail was incorrect for about 1% of the discharges. Some facilities in North Carolina reused their record identifiers across fiscal years (starting each October). This means that two distinct discharges share an identical state-supplied record identifier. The charge detail for the different discharges were erroneously combined because of the identical record identifiers. There is no way to determine which HCUP records have this problem.

Prior to 2002, North Carolina provided 10 detail charges.

Overview

Revenue codes (REVCDn) identify the revenue center for which the detailed charges (CHGn) apply in the number of units (UNITn) given. For example, CHG1 applies to the revenue center in REVCD1 and the units of service specified in UNIT1. Units are not required for all revenue sources; the unit's field may be coded as missing (.) or zero.

Caveats

For 2000-2004, if total charges are identified in the detail charges (REVCDn = "001"), the corresponding detail charge, unit, and revenue code are set to missing. Beginning with 2005, total charges are kept in the detailed charges.

Outpatient revenue codes (REVCDn = 500 or 509) are used when patient is admitted as an inpatient before midnight of the day following the date of service. Late discharges for medical necessity are to be shown under Discharge, Medically Necessary (REVCDn = 224), rather than under room charge. Hourly nursing charges are in addition to room and board for ICU and CCU. Other Drugs (REVCDn = 259) is a code for "Generic Take Home Drugs." Treatment or Observation Room revenue codes are used when the patient is held in an observation room and then subsequently admitted.

Invalid Revenue Codes

Revenue codes in 1988-1992 were kept as reported; no validity check was performed. In 1993-1994, invalid revenue codes (values less than 100, greater than 999, and alpha-numeric codes) were set to "A" (REVCDn = "A"). Starting in 1995, invalid codes were set to missing (REVCDn = " ").

Detailed charges (CHGn) are associated with identified revenue centers (REVCDn) and units of service (UNITn). For example, CHG1 applies to the revenue center in REVCD1 and the units of service specified in UNIT1. West Virginia reports detailed charges (CHGn) associated with standard UB-92 revenue codes stored in REVCDn. West Virginia does not collapse or redefine ranges of revenue codes.

The first 12 variables in each array (CHG1-CHG12, REVCD1-REVCD12, and UNIT1-UNIT12) are reserved for room and board services; the remaining variables are used for ancillary services.
