Causes by organ system[edit | edit source] To obtain the coding for the table seen below, click here. You need to copy the table content from the edit box, and paste it into the edit box. You can then list the causes by organ system. List the causes, separated by a comma under the appropriate category where it says "No underlying causes". Erase "No underlying causes" if you are listing causes in that category. For an example of the causes by organ system table in a causes microchapter, click here.
