20  Decisions about necessary data fields and subjects
 (1) If the Chief Executive Medicare is satisfied that it is reasonably necessary to match information for a permitted purpose, the Chief Executive Medicare must decide the following:
 (a) the data fields in a dataset containing the information that are necessary for the matching;
 (b) the data subjects (for example, individuals or classes of individuals) in a dataset containing the information that are necessary for the matching.
 (2) In making a decision mentioned in subsection (1), the Chief Executive Medicare must consider the following:
 (a) how the data fields and data subjects that are necessary for the matching can be minimised (for example, by validating existing data rather than seeking new data or by using predefined variables);
 (b) how the use of personal information can be minimised (for example, by using identifiers rather than personal information).
