List of all CCIs and their categories;

• click on any of those categories to see a list of the other pages in that category:
• add {{ICD10 category|category name}} to any ICD10 page in the same spot as the others that are already there.
• Suggestion while we are reviewing these: if you are going to review a bunch of them, an efficient way to to it is to open all in other tabs first and then work your way through them, closing the tabs as you finish with them; then edit this page, make no change, and save it to update the list and see if you got everything.
