 ;
 ; There are 3 types of charges/items:
 ; - ITEM: charge for an individual item:  specific item has one or more charge entries in 363.2
 ;   for the charge to be applied to the bill the specific item must be found on the bill
 ;
 ; - EVENT: charge for an event, not an item:  items are defined in 363.2
 ;   all charge items active on a date in the set define the charge for the event
 ;   the item does not need to be defined on the bill for the charge to be applied to the bill
 ;   the charge set on a date becomes the events charge, so effective date cuts across item and applies to event
 ;   all charge items with the same effective date are used to calculate the event charge for that date
 ;   each charge item effective date in the set overrides all previous entries in the set regardless of item
 ;
 ; - VA COST:  charge for an individual item but no entries in 363.2
 ;   instead the charge is calculated/obtained when it is needed from an interface with the source package
 ;
 ;
 ; Auto calculation and filing of a bills charges
 ;
 ; IBCRBC (BILL) - determine if charges can be calculated and which rates (RS/CS) should be used
 ;                 then find billable items/events, calculate and store the charges
 ;                 called anytime a bills charges need to be updated
 ;        
 ;                 IBCRBC1 (event) - gather billable items/events for each billable event type
 ;                                   then accumulate all charges for the bill for each billable event/item
 ;
 ;                                   IBCRCGx (event) - pull billable items/events from the bill
 ;                                   IBCRBC2 (BITMCHRG) - calculate charges for billable item/event
 ;
 ;                 IBCRBC3 (SORTCI) - sort accumulated charges into order to store on bill, combine if possible
 ;                 IBCRBC3 (ADDBCHRGS) -  store the sorted accumulated charges on the bill
 ;
 ;
 ; The Billable Event of the Charge Set is directly related to the Type of charge assigned
 ; to the charges calculated for that Charge Set.  So, Billable Event (363.1,.03) <-> Type (399,42,.1)

 ; Inpatient Bill Dates use follow rules:
 ; - admission date is counted as billable
 ; - the discharge date is not billable and is not counted
 ; 
 ; - if admission movement is found in the Patient Movement file then the dates of admission and discharge
 ;   will be used as the outside limits of the LOS, even if date range of the bill is longer   (LOS^IBCU64)
 ; 
 ; - a day is counted as billable to the bedsection the patient was in at the end of the day (ie. counted
 ;   in LOS of next movement after midnight)
 ; - if there is a movement on any given date that date is included in the LOS of the bedsection the patient
 ;   moved into (same as admission date)
 ; - if there is a movement on any given date that date is NOT included in the LOS of the bedsection the 
 ;   patient moved out of (same as discharge date)
 ; 
 ; - if the time frame of the bill is:
 ;   - either interim-first or interim-continuous the last date on the bill should be billed
 ;     - if the last date is counted it is added to the LOS of the bedsection the patient was in at the end
 ;       of the day
 ;   - either NOT interim-first or interim-continuous (final bills) the last date on the bill
 ;     should NOT be billed (i.e. this is considered the discharge date)
 ;
 ; - start with first bedsection after begin date, day is counted in the bedsection the patient is in at midnight
 ; - continuous: last bedsection counted is the bedsection the patient is in at midnight of the end date
 ; - final:last bedsection counted is the bedsection the patient is in at midnight of the day before the end date
