Relationship between Code Sets

You can establish a relationship between two code sets (ex: Subtype and ItemType) using the ItemCodeLike rule. You would then use one-character codes in the parent code set (ex: Subtype) and two-character codes in the related code set (ex: ItemType) where the first characters correspond to the codes in the parent code set.

For example, Permits might use the following codes in the Subtype code set.

sysadmin_22

And Permits might use the following corresponding codes in the ItemType code set.

sysadmin_23
