FBAAVD4 ;AISC/CLT, Special routine for entering/inactivating/deleting NPI in file 161.2; ; 19 Sep 2006  12:31 PM
 ;;3.5;FEE BASIS;**98**;30-JAN-95;Build 54
 ;;Per VHA Directive 10-93-142, this routine should not be modified.
 ;
 ;This routine will ask for the NPI, check for proper format, check for duplicate entries
 ;check for proper format using the double-add-double formula.  If the NPI is being
 ;deleted it will check if it is being deleted because of a valid NPI being removed for some
 ;other reason.  If it is being deleted because of an erroneous entry it will be completely deleted.
 ; If it is a valid NPI being deleted because of a possible inappropriate usage it will be maintained
 ; in the history cross reference to preclude anyone from using this NPI again.
