The list contains the ICD Codes used by the app.
You can type part of the code/name into the box to filter the list. Anything entered must be as it appears in the list for example: 'congenital' will return 22 results, 'congenital zika' returns a single result, and 'zika congenital' does not return anything.
If the code you want to use is not in the list (please check) then you can type in the code and name. The details will be saved for this list only (eg. not for other observations or cases, where you would have to add it again as needed).
