Although there is the functionality to bulk add (batch add) codes in EMIS Web, we would not recommend this for ethnicity. Using the batch add option would apply the same code and date of entry for all patients included in the search. 

For further information on the Ardens reports to identify patients with missing ethnicity codes, please see the following support article. 

If you require any further assistance on the process above, please contact Ardens support on: support-emis@ardens.org.uk
