 COMMENT:	Starting in 2011, with version J of the NCH claim 
		layout, institutional claims can have up to 25 
		diagnosis codes (previously only 11 were acommodated), 
		and the non-institutional claims can have up to 12 
		diagnosis codes (previously only up to 8). 
 
		Effective with Version 'J', this field has been
 		expanded from 5 bytes to 7 bytes to accommodate
 		the future implementation of ICD-10.
 
		ICD-10 is not scheduled for implementation 
		until 10/2015.
