IBCRCI ;ALB/ARH - RATES: CALCULATION ITEM/EVENT COST FNCTNS ; 22-MAY-96
 ;;2.0;INTEGRATED BILLING;**52,106,245**;21-MAR-94
 ;;Per VHA Directive 10-93-142, this routine should not be modified
 ;
 ;       standard callable functions to get item charge/cost
 ;
 ; notice that each function works for all Charge Methods and both types of Sets (Item/Event)
 ; - if the Charge Set is based on event then the event charge will be calculated (item passed will not be used)
 ; - the charges are the unit charges so UNIT should only be defined (or not 1) if the Charge Method is Quantity
 ;
ITCHG(CS,ITEM,EVDT,MOD) ; returns total base unit charge for a specific charge set, item/event and date
 ; works for both types of Charge Set (Item and Event) and all Charge Methods
 ; does not factor in division, units or rate schedule adjustment
 ; if charges for the Set are based on event rather than item, will get active events, ITEM is not required/used
 ; Input:  CS = Charge Set ifn, ITEM = billable item pointer, MOD = cpt modifier
 ; Output: total item charge on EVDT ^ effective date of charge ^ total base charge

 ; units should be 1 or undefined unless the Charge Method of the rate is Quantity/Miles/Minutes/Hours
