 ;
 ; there are two types of Charge Sets (363.1) that have Charge Item entries (363.2):
 ; 1 - ITEM: each item has an individual charge:  an item on the bill has corresponding charge item entries,
 ;     the item may have more than one Charge Item entry but they are specifically defined for that item
 ;     ex: an inpt bs, a CPT, or a drug
 ; 2 - EVENT: the charge is for an event not an item:  all charge items active on a date in the Set 
 ;     combine to give the charge for the item on the bill for that date
 ;     all items in the set define the event charge - the total charges for a set on a date is the event charge
 ;     the item does not have to match an item on the bill and is only relevant because it is then added
 ;     to the RC multiple of the bill as one of the bills charge lines
 ;     ex:  the charge for a bills opt visit date is the combined charge of all items active in the Set
 ;          on the visit date (this may be more than simply the Outpatient Visit Date bedsection charge if
 ;          there is another bedsection charge defined for that date)
 ;
CSITMS(CS) ; returns 1 (ITEM) if the CS requires a single billable item or 2 (EVENT) if all active items for date are used
