Type a diagnosis in the search window and make a selection. The diagnosis will be added to the list.
To arrive at a complete diagnosis, make selections from the top menus to narrow down the options. You can start anywhere (e.g., first selecting "right" under Laterality will cut your options almost in half).
When all diagnoses are bull's eyes, the final step is to update the coding documents. Scroll down to the Discharge Order box, click on the blue down arrow and select Update Coding Documents.
