What Is The Difference Between The Standard Implementation Guide, Data Dictionary and External Code List (ECL)?
An NCPDP Standard Implementation Guide usually contains the data layout or format of transaction(s). It contains technical rules and guidance for the format. Additionally, it provides information about the transaction(s), including business rules, guidance for usage, matrices of usage, and examples.

An NCPDP Data Dictionary contains the field identifiers, format, values, descriptions, and reject codes for the data elements supported in the various NCPDP Standards. It is intended to go hand-in-hand with a standard and implementation guide.

An NCPDP External Code List (ECL) contains values, descriptions, and reject codes for a subset of the data elements supported in the current NCPDP Standards. It is intended to go hand-in-hand with the Data Dictionary and is a subset of that document. (Click here to view the ECL Process Overview)

Note: Older Standard versions consisted of a Standard document and an Implementation Guide document. The Standard document contained the technical rules, data layout and fomat while the Implementation Guide provided information on the transaction(s), guidance for usage, and examples.Over a period of time these two documents were combined into one Standard Implementation Guide for each standard.
