VAFHAPV1 ;ALB/RJS - INPATIENT PV1 SEGMENT ; 10/8/04 11:28am
 ;;5.3;Registration;**91,209,190,298,494,621**;Aug 13, 1993
 ;
 ;The DGBUILD entry point is call used internally by MAS software
 ;to build a PV1 Segment for deleted Admissions. The DGPMP
 ;variable, available from the DGPM Event Driver at the time of
 ;the deletion, makes it possible to construct a partial PV1 segment
 ;for the deleted record.
 ;
 ;06/29/00 ACS - Added sequence 21 (physical treating specialty - ward
 ;location) and sequence 39 (facility + suffix).
 ;
EN(DFN,VAFHDT,VAFSTR,IEN,ALTVISID,SETID,VAFDIAG) ;
 ;
 ;This Entry Point builds the HL7 PV1 segment for inpatients.
 ;
 ;DFN, VAFHDT, & VAFSTR are the required variables.
 ;
 ;            DFN = IEN of Patient File
 ;         VAFHDT = Date/Time of Patient Movement
 ;         VAFSTR = HL7 Fields Requested e.g. ",3,7,10"
 ;
 ;IEN, ALTVISID, SETID are the optional variables
 ;
 ;The optional variable IEN is used for Discharge movements
 ;because if only Date/Time is passed for a Discharge movement
 ;no useful information is returned by VADPT.
 ;
 ;The optional ALTVISID variable is used to pass in a "Alternate.
 ;Visit ID" this is a unique number that 
 ;identifies this Admission or episode of care
 ;
 ;The optional variable SETID can be used to differentiate 
 ;different sets of data, in messages that may contain multiple
 ;events or messages.
 ;
 ;VAFDIAG, is a passed as a dotted variable. The inpatient diagnosis
 ;is then returned in this variable.
